Description

顔検出防止具Face detection prevention device
　本発明は顔検出防止具に関する。詳しくは、盗撮やカメラの写りこみによるプライバシー侵害を防止する顔検出防止具に関する。 The present invention relates to a face detection preventing device. More specifically, the present invention relates to a face detection prevention device for preventing privacy infringement due to voyeurism or camera reflection.
　カメラ付き携帯端末の普及、ソーシャル・ネットワーキング・サービス（ＳＮＳ）及び画像検索技術の進展により、無断で撮影・開示された写真を通じて、被撮影者がいつ・どこにいたかという情報が暴露されることになり、被撮影者のプライバシー保護が求められている。このため、盗撮やカメラの写り込みによるプライバシー侵害を防止する本質的な対策が求められている。 With the spread of mobile terminals with cameras, social networking service (SNS), and the development of image search technology, information on when and where the subject was photographed will be exposed through photographs taken and disclosed without permission. Therefore, the privacy protection of the photographed person is required. For this reason, essential measures to prevent privacy infringement due to voyeurism and camera reflection are required.
　従来手法として、顔面を物理的に隠すことで、他人のカメラへの写りこみを防ぐ手法、顔面に特殊なパターンを描き、顔認識を失敗させることで個人の同定を防ぐ手法があった。［非特許文献１，２参照］　他方、発明者達は、人の視覚には影響を与えずにデジタルカメラの撮影映像にノイズを付加する赤外線光源を映像表示装置に組み込むことで盗撮を防止する方法を提案した。［非特許文献３，４参照］ As a conventional method, there were a method of preventing the other person's camera from being reflected by physically hiding the face, and a method of preventing a person from being identified by drawing a special pattern on the face and failing the face recognition. [Refer to Non-Patent Documents 1 and 2] On the other hand, the inventors prevent voyeurism by incorporating an infrared light source in a video display device that adds noise to the video captured by a digital camera without affecting human vision. A method was proposed. [See Non-Patent Documents 3 and 4]
　しかしながら、上記いずれの従来手法も、顔面の隠ぺいや着色により顔面を変える必要があるため、物理空間における人対人のコミュニケーションに支障をきたすという問題があった。すなわち、自然なコミュニケーションとプライバシー保護を両立するような顔検出防止具を実現する必要があった。 However, any of the conventional methods described above has a problem in that it interferes with communication between people in the physical space because it is necessary to change the face by hiding or coloring the face. That is, it is necessary to realize a face detection preventing device that achieves both natural communication and privacy protection.
　本発明は、自然なコミュニケーションとプライバシー保護を両立するような顔検出防止具を実現することを目的とする。 The object of the present invention is to realize a face detection preventing device that achieves both natural communication and privacy protection.
　上記課題を解決するために、本発明の第１の態様における顔検出防止具は、例えば図１０に示すように、人物の顔に装着し、カメラで撮影された撮影画像の検出領域８（図２参照）における輝度の評価を通して、撮影画像の中から人物の顔を検出する顔判別器１１（図３参照）による検出領域８における輝度の評価を変更させる顔検出防止具において、人物の顔の特定領域に対向するように配置される部材３Ａ（図１０参照）と、部材３Ａを人物の顔に装着する装着部５Ａとを備え、部材３Ａは、特定領域としての、検出領域８において輝度が低く評価される人物の顔の位置に対向するように配置されて、輝度を高く変化させる高輝度化部材４Ａを有する、又は、特定領域としての、検出領域において輝度が高く評価される人物の顔の位置に対向するように配置されて、輝度を低く変化させる低輝度化部材を有する。 In order to solve the above-described problem, the face detection preventing device according to the first aspect of the present invention is attached to a human face and detected by a camera in a detection area 8 (see FIG. 10). In the face detection preventer that changes the evaluation of the luminance in the detection area 8 by the face discriminator 11 (see FIG. 3) that detects the human face from the captured image through the luminance evaluation in A member 3A (see FIG. 10) disposed so as to face the specific area and a mounting portion 5A for mounting the member 3A on the face of the person, the member 3A has a luminance in the detection area 8 as the specific area. The face of a person who is arranged so as to face the position of the face of the person who is evaluated to be low and has a high brightness member 4A which changes the brightness to be high, or whose brightness is highly evaluated in the detection area as a specific area Position of It disposed so as to face, with a low brightness member for varying low luminance.
　ここにおいて、顔検出防止具とは、盗撮や写り込みによる撮影画像がインターネット上に流出した時に、顔検出器（ソフトウェア）により人物の顔が検出されることを防止するために、人物が顔に装着するものをいうこととする。また、「人物の顔に装着する」には、顔に直接装着する他に、間接的に装着（直接装着するものに装着）するものを含むものとする。また、検出領域とは撮影画像中で顔の検出を行なおうとする領域である。また、検出領域の輝度の評価には、検出領域における輝度値の２次元分布に基づく評価（例えば、第１の領域の平均輝度値と第２の領域の平均輝度値の差分）も含まれる。また、装着部は、典型的には、眼鏡型やゴーグル型の場合はつるの部分、バイザー型の場合は頭部を取り巻く帯状部分（一部に切れ目があても良い）、シート状の場合は接着剤の部分、板状の場合は蝶番や嵌め込み部分等である。また、高輝度化部材としては、例えば赤外線反射フィルター、再帰反射ビーズやミラーを利用した部材等を使用できる。低輝度化部材としては、例えば赤外線吸収フィルター、ルーバーを利用した部材等を使用できる。また、顔判別器の性能によるが、人物の顔の特定領域として、輝度が低く評価される人物の顔の位置には、例えば眼の部分等が該当する。輝度が高く評価される人物の顔の位置には、例えば鼻筋の部分や両眼の間の部分等が該当する。また、人物の顔の特定領域に対向する位置とは、顔検出防止具を装着した時に、正面から見て、人物の顔の特定領域と重なり合う部材の部分をいうものとする。高輝度化部材又は低輝度化部材は、正面から見て、人物の顔の特定領域を覆うように配置されるのが理想的であるが、必ずしも全部を覆うように配置される必要はなく、顔判別器の判定を誤らせるのに十分であれば良い（例えば、反射率や顔判別器の性能に依存するが、反射率が十分高ければ７０％以上覆えば良い等である）。なお、本明細書で、部材について「眼を覆う部分」、「両眼を横切る」、「眼から離れた部分」又はこれらに準ずる表現が使用されるが、「眼に対向する（又は対応する）部分を覆う部分」、「両眼に対向する（又は対応する）部分を横切る」、「眼に対向する（又は対応する）部分から離れた部分」等を意味するものである。 Here, the face detection preventive tool refers to a person's face in order to prevent the face detector (software) from detecting a person's face when an image shot by voyeurism or reflection is leaked on the Internet. The thing to wear is said. Further, “wearing on a person's face” includes not only wearing directly on the face but also indirectly wearing (wearing on a person wearing directly). The detection area is an area where a face is to be detected in the captured image. The evaluation of the luminance of the detection area also includes evaluation based on the two-dimensional distribution of luminance values in the detection area (for example, the difference between the average luminance value of the first area and the average luminance value of the second area). In addition, the wearing part is typically a vine part in the case of glasses or goggles, a belt-like part that surrounds the head in the case of a visor type (parts may have cuts), and in the case of a sheet In the case of an adhesive part, in the case of a plate, it is a hinge or a fitting part. Further, as the high brightness member, for example, an infrared reflection filter, a member using retroreflective beads or a mirror, or the like can be used. As the brightness reducing member, for example, an infrared absorption filter, a member using a louver, or the like can be used. Further, depending on the performance of the face discriminator, for example, an eye part corresponds to the position of the face of the person whose luminance is evaluated as low as the specific area of the face of the person. The position of the face of a person whose brightness is highly evaluated corresponds to, for example, a nose portion or a portion between both eyes. Further, the position facing the specific area of the person's face refers to the part of the member that overlaps the specific area of the person's face when viewed from the front when the face detection preventive tool is worn. Ideally, the high brightness member or the low brightness member is arranged so as to cover a specific area of the face of the person when viewed from the front, but it is not necessarily arranged so as to cover the whole, It suffices if it is sufficient to mislead the face discriminator (for example, depending on the reflectivity and the performance of the face discriminator, 70% or more may be covered if the reflectivity is sufficiently high). In this specification, “a part covering the eyes”, “crossing both eyes”, “a part away from the eyes” or an equivalent expression is used for the member. ) "Part covering the part", "crossing the part facing (or corresponding) to both eyes", "part away from the part facing (or corresponding) to the eye", and the like.
　本態様のように構成すると、光源を使用することなく、人物の顔を検出する顔判別器の輝度の評価を変更させるので、自然なコミュニケーションとプライバシー保護を両立するような顔検出防止具を実現することができる。 When configured in this manner, the brightness evaluation of the face discriminator that detects a person's face is changed without using a light source, thus realizing a face detection prevention device that achieves both natural communication and privacy protection. can do.
　また、本発明の第２の態様における顔検出防止具は、第１の態様において、例えば図１０に示すように、部材３Ａは高輝度化部材として、緑色光を透過し、赤外線、赤色光、青色光、紫色光、紫外線のいずれかを反射する赤外線等反射部材を有する。 Further, in the face detection preventing device according to the second aspect of the present invention, in the first aspect, for example, as shown in FIG. 10, the member 3 </ b> A is a high brightness member that transmits green light, infrared light, red light, A reflection member such as an infrared ray that reflects blue light, purple light, or ultraviolet light is provided.
　ここにおいて、赤外線と紫外線は人間の眼に感知されず、カメラに感光するので、これらを用いるのが好ましい。しかし、人間の眼は緑色の光に感じる割合が約７０％で最も大きいので、緑色光を透過すればさほど違和感はない。したがって、赤色光、青色光、紫色光を反射させても良い。赤外線又は紫外線にこれらの光を追加すると、輝度を変化させる波長領域を広くし、変化量を大きくし、顔検出の防止効果を大きくできる。また、赤色光や紫色光のみを使用することも可能である。緑色光を透過し、赤外線等を反射するとは、入射する光のうち赤外線、赤色光、青色光、紫色光、紫外線のいずれかの全エネルギー量に対して反射するエネルギー量の割合が５０％以上、緑色光の全エネルギー量に対して透過するエネルギー量が５０％以上であることをいう。好ましくは、赤外線等を６０％以上反射し緑色光を６０％以上透過する。さらに好ましくは、赤外線等を８０％以上反射し緑色光を８０％以上透過する。 Here, it is preferable to use infrared rays and ultraviolet rays because they are not perceived by human eyes and are sensitive to the camera. However, the ratio of human eyes to green light is the largest at about 70%, so there is not much discomfort if green light is transmitted. Therefore, red light, blue light, and violet light may be reflected. When these lights are added to infrared rays or ultraviolet rays, the wavelength region in which the luminance is changed can be widened, the amount of change can be increased, and the effect of preventing face detection can be increased. It is also possible to use only red light or purple light. Transmitting green light and reflecting infrared rays means that the ratio of the amount of energy reflected to the total amount of any of infrared, red, blue, violet, and ultraviolet rays in incident light is 50% or more. The amount of energy transmitted through the total amount of green light is 50% or more. Preferably, 60% or more of infrared rays or the like is reflected, and 60% or more of green light is transmitted. More preferably, 80% or more of infrared rays are reflected and 80% or more of green light is transmitted.
　本態様のように構成すると、輝度の評価を変更させる部材として、赤外線等反射部材を使用することにより、装着者にあまり違和感を与えず、カメラへの感光量を増加させるので、効果的な顔検出防止ができる。 With this configuration, an effective face can be obtained by using a reflection member such as an infrared ray as a member for changing the evaluation of luminance, so that the wearer does not feel a sense of incongruity and the amount of exposure to the camera is increased. Detection can be prevented.
　また、本発明の第３の態様における顔検出防止具は、第２の態様において、例えば図３に示すように、顔判別器１１は、Ｈａａｒ－ｌｉｋｅ特徴量を用いて検出領域８における輝度を評価する複数の弱判別器から構成された強判別器１０ａ～１０Ｎを複数連結し、連結された複数の強判別器１０ａ～１０Ｎによる順次判定に基づいて、検出領域８に顔が有るか否かを判定することにより、人物の顔を検出するものであり、赤外線等反射部材は、Ｈａａｒ－ｌｉｋｅ特徴量で輝度が低く評価される矩形特徴に対応する人物の顔の位置に配置される赤外線等反射フィルターである。 In addition, in the face detection preventing device according to the third aspect of the present invention, in the second aspect, for example, as shown in FIG. 3, the face discriminator 11 uses the Haar-like feature value to increase the luminance in the detection region 8. Whether or not there is a face in the detection region 8 based on sequential determination by the plurality of strong discriminators 10a to 10N connected to each other by connecting a plurality of strong discriminators 10a to 10N composed of a plurality of weak discriminators to be evaluated. The infrared ray reflection member is an infrared ray arranged at the position of the human face corresponding to the rectangular feature whose luminance is evaluated to be low by the Haar-like feature amount. It is a reflection filter.
　ここにおいて、赤外線等反射フィルターは赤外線や赤色光を反射する材料で製作されたものでもよく、塗料を塗ることによって赤外線や赤色光を反射する特性を持たせてもよい。また、「矩形特徴に対応する人物の顔の位置」とは、撮影画像内の矩形特徴に重なる顔の部分に対応する実際の人物の顔の部分をいうものとする。
　本態様のように構成すると、顔検出器の大多数がＨａａｒ－ｌｉｋｅ特徴量を用いているので、大多数の撮影画像を盗撮から防止できる。 Here, the reflection filter such as infrared rays may be made of a material that reflects infrared rays or red light, and may have a characteristic of reflecting infrared rays or red light by applying a paint. In addition, the “position of the person's face corresponding to the rectangular feature” refers to an actual person's face corresponding to the portion of the face that overlaps the rectangular feature in the captured image.
According to this configuration, since the majority of face detectors use Haar-like features, the majority of captured images can be prevented from voyeurism.
　また、本発明の第４の態様における顔検出防止具は、第１の態様において、例えば図４１又は図４２に示すように、部材３Ａは高輝度化部材として、赤外線、赤色光、青色光、紫色光、紫外線のいずれかを再帰的に反射する又は広角に反射する微小反射体を視線を遮らない部分に散在させた赤外線等反射部材を有する。 Further, the face detection preventive tool according to the fourth aspect of the present invention is the first aspect, as shown in FIG. 41 or 42, for example, the member 3A is a high brightness member, and infrared, red light, blue light, It has a reflection member such as an infrared ray in which minute reflectors that reflect either violet light or ultraviolet light recursively or are reflected at a wide angle are scattered in portions that do not block the line of sight.
　ここにおいて、再帰的に反射する（光を入射方向に反射する）微小反射体として、例えば数μｍ～数ｍｍの再帰反射ビーズ等を使用できる。また、広角に反射する微小反射体として、例えば数μｍ～数ｍｍのミラーボール（半球状の反射体）等を使用できる。また、「視線を遮らない部分」とは、日常活動において視線を遮らない部分を意味し、顔検出防止具で眼の前に無い部分、すなわち、額の前、頬の前、鼻の前や、右眼の右斜め前側の部分、左眼の左斜め前側の部分等をいう。
　本態様のように構成すると、再帰反射により、顔判別器の検出を誤らせることができる。さらに微小反射体が視線を遮らない部分に有るので、装着者は顔検出防止具を通して装着前と同様な景色を見ることができる。 Here, as a micro-reflector that recursively reflects (reflects light in the incident direction), for example, a retroreflective bead of several μm to several mm can be used. Further, as a micro-reflector that reflects at a wide angle, for example, a mirror ball (hemispherical reflector) of several μm to several mm can be used. In addition, “a part that does not block the line of sight” means a part that does not block the line of sight in daily activities, and is a part that is not in front of the eyes with a face detection prevention device, that is, in front of the forehead, in front of the cheek, in front of the nose or , A portion on the right oblique front side of the right eye, a portion on the left oblique front side of the left eye, etc.
If comprised like this aspect, the detection of a face discriminator can be made erroneous by retroreflection. Furthermore, since the minute reflector is in a portion that does not block the line of sight, the wearer can see the same scenery as before wearing through the face detection prevention tool.
　また、本発明の第５の態様における顔検出防止具は、第１の態様において、例えば図１８に示すように、部材は低輝度化部材４Ｂ０として、緑色光を透過し、赤外線、赤色光、青色光、紫色光、紫外線のいずれかを吸収する赤外線等吸収部材を有する。 Further, the face detection preventing device according to the fifth aspect of the present invention is the first aspect, as shown in FIG. 18, for example, as shown in FIG. It has an absorbing member such as an infrared ray that absorbs blue light, purple light, or ultraviolet light.
　ここにおいて、赤外線と紫外線を用いるのが好ましい。しかし、赤色光、青色光、紫色光を吸収させても良い。赤外線又は紫外線にこれらの光を追加すると、輝度を変化させる波長領域を広くし、変化量を大きくし、顔検出の防止効果を大きくできる。また、赤色光や紫色光のみを使用することも可能である。緑色光を透過し、赤外線等を吸収するとは、入射する光のうち赤外線、赤色光、青色光、紫色光、紫外線のいずれかの全エネルギー量に対して吸収するエネルギー量の割合が５０％以上、緑色光の全エネルギー量に対して透過するエネルギー量が５０％以上であることをいう。好ましくは、赤外線等を６０％以上吸収し緑色光を６０％以上透過する。さらに好ましくは、赤外線等を８０％以上吸収し緑色光を８０％以上透過する。
　本態様のように構成すると、輝度の評価を変更させる部材として、赤外線等吸収部材を使用することにより、人物にあまり違和感を与えず、カメラへの感光量を減少させるので、効果的な顔検出防止ができる。 Here, it is preferable to use infrared rays and ultraviolet rays. However, red light, blue light, and violet light may be absorbed. When these lights are added to infrared rays or ultraviolet rays, the wavelength region in which the luminance is changed can be widened, the amount of change can be increased, and the effect of preventing face detection can be increased. It is also possible to use only red light or purple light. Transmitting green light and absorbing infrared light means that the ratio of the amount of energy absorbed to the total energy amount of any of infrared light, red light, blue light, violet light, and ultraviolet light is 50% or more. The amount of energy transmitted through the total amount of green light is 50% or more. Preferably, 60% or more of infrared rays or the like is absorbed, and 60% or more of green light is transmitted. More preferably, it absorbs 80% or more of infrared light and transmits 80% or more of green light.
With this configuration, effective face detection is achieved by using an infrared absorbing member or the like as a member for changing the evaluation of luminance, thereby reducing the amount of exposure to the camera without causing a sense of incongruity to the person. It can be prevented.
　また、本発明の第６の態様における顔検出防止具は、第５の態様において、例えば図３に示すように、顔判別器１１は、Ｈａａｒ－ｌｉｋｅ特徴量を用いて検出領域８における輝度を評価する複数の弱判別器から構成された強判別器１０ａ～１０Ｎを複数連結し、連結された複数の強判別器１０ａ～１０Ｎによる順次判定に基づいて、検出領域に顔が有るか否かを判定することにより、人物の顔を検出するものであり、赤外線等吸収部材は、Ｈａａｒ－ｌｉｋｅ特徴量で輝度が高く評価される矩形特徴に対応する人物の顔の位置に配置される赤外線等吸収フィルターである。 In addition, in the face detection preventing tool according to the sixth aspect of the present invention, in the fifth aspect, as shown in FIG. 3, for example, the face discriminator 11 uses the Haar-like feature value to increase the luminance in the detection region 8. A plurality of strong classifiers 10a to 10N composed of a plurality of weak classifiers to be evaluated are connected, and whether or not there is a face in the detection region is determined based on sequential determination by the connected plurality of strong classifiers 10a to 10N. The person's face is detected by the determination, and the infrared ray absorbing member is an infrared ray absorbing member arranged at the position of the person's face corresponding to the rectangular feature whose luminance is highly evaluated by the Haar-like feature amount. It is a filter.
　ここにおいて、赤外線等吸収フィルターは赤外線や赤色光を吸収する材料で製作されたものでもよく、塗料を塗ることによって赤外線や赤色光を吸収する特性を持たせてもよい。
　本態様のように構成すると、顔検出器の大多数がＨａａｒ－ｌｉｋｅ特徴量を用いているので、大多数の撮影画像を盗撮から防止できる。 Here, the infrared filter or the like may be made of a material that absorbs infrared light or red light, or may have a characteristic of absorbing infrared light or red light by applying a paint.
According to this configuration, since the majority of face detectors use Haar-like features, the majority of captured images can be prevented from voyeurism.
　また、本発明の第７の態様における顔検出防止具は、第１の態様において、例えば図３７に示すように、部材３Ａは低輝度化部材として、赤外線、赤色光、青色光、紫色光、紫外線のいずれかを吸収する表面に垂直な方向に幅を有する線状吸収体を表面に平行な方向に一様な間隔で並べた赤外線等吸収部材を有する。 Further, the face detection preventive tool according to the seventh aspect of the present invention is the first aspect, as shown in FIG. 37, for example, as shown in FIG. 37, the member 3A is a member for reducing the brightness, such as infrared light, red light, blue light, purple light, It has an infrared-absorbing member in which linear absorbers having a width in a direction perpendicular to the surface that absorbs any ultraviolet light are arranged at a uniform interval in a direction parallel to the surface.
　ここにおいて、線状吸収体として例えば０．１～数ｍｍの間隔に並べられたルーバーを使用できる。ルーバーは例えば携帯端末の表示部に使用されて、画面を正面から見ることができるが、見る角度を斜めにしていくにつれて見えにくくなり、所定角度（例えば６０度）を越えると見えなくなる。また、線状吸収体の方向は部材の表面に平行な方向であれば任意の方向で良い。

［顔検出の概要］
　顔検出は、顔を理解するための顔画像処理技術として、最も重要で基礎的な技術であり、顔認識の前処理として用いられている。顔検出の中で最も良く知られた手法は、ＶｉｏｌａとＪｏｎｅｓによって２００１年発表されたアルゴリズムである［Ｐ．Ｖｉｏｌａ　ａｎｄ　Ｍ．Ｊｏｎｅｓ，“Ｒｏｂｕｓｔ　Ｒｅａｌ－Ｔｉｍｅ　Ｆａｃｅ　Ｄｅｔｅｃｔｉｏｎ，”Ｉｎｔｅｒｎａｔｉｏｎａｌ　Ｊｏｕｒｎａｌ　ｏｆ　Ｃｏｍｐｕｔｅｒ　Ｖｉｓｉｏｎ，（ＩＪＣＶ），Ｖｏｌ．５７，Ｎｏ．２，ｐｐ．１３４－１５７，２００４年　参照］。Ｖｉｏｌａらが提案した顔検出手法（Ｖｉｏｌａ－Ｊｏｎｅｓ法）は、Ｈａａｒ－ｌｉｋｅ特徴量、積分画像法、判別器のカスケード構成という３つの主要な概念から構成されたアルゴリズムで、高い精度と高速な検出処理を実現している。現在大多数の顔検出手法はこのＶｉｏｌａ－Ｊｏｎｅｓ法を使用している。以降に、Ｈａａｒ－ｌｉｋｅ特徴量と判別器のＣａｓｃａｄｅ構成について概説する。 [Overview of face detection]
Face detection is the most important and basic technique as a face image processing technique for understanding the face, and is used as preprocessing for face recognition. The best known method of face detection is the algorithm published in 2001 by Viola and Jones [P. Viola and M.M. Jones, “Robust Real-Time Face Detection,” International Journal of Computer Vision, (IJCV), Vol. 57, no. 2, pp. 134-157, 2004]. The face detection method (Viola-Jones method) proposed by Viola et al. Is an algorithm composed of three main concepts: Haar-like features, integral image method, and cascade configuration of discriminators, with high accuracy and high speed detection. Processing is realized. The majority of face detection methods currently use the Viola-Jones method. In the following, an outline of the Haar-like feature quantity and the Cascade configuration of the discriminator is described.
［Ｈａａｒ－ｌｉｋｅ特徴量］
　図１にＨａａｒ－ｌｉｋｅ特徴の例を示す。図１（ａ）～図１（ｇ）に複数のＨａａｒ－ｌｉｋｅ特徴の基本パターン（矩形特徴）９ａ～９ｇが定義されている。Ｈａａｒ－ｌｉｋｅ特徴の基本パターン９ａ～９ｇは、それぞれ、第１の領域（一方向の斜線で示された領域）ｒ１とそれに隣接する第２の領域（交差する二方向の斜線で示された領域）ｒ２で構成される。Ｈａａｒ－ｌｉｋｅ特徴量は、画像における特徴量であり、次式（１）のように、第１の領域ｒ１の平均輝度ｓ（ｒ１）と第２の領域ｒ２の平均輝度ｓ（ｒ２）の差をとることで得られる。Ｈａａｒ－ｌｉｋｅ特徴量は、第１の領域の輝度が第２の領域の輝度に比して相対的に高ければ正（＋）に、相対的に低ければ負（－）になる。

　ｈ（ｒ１，ｒ２）＝ｓ（ｒ１）－ｓ（ｒ２）・・・・（１）
[Haar-like feature value]
FIG. 1 shows an example of the Haar-like feature. In FIG. 1A to FIG. 1G, a plurality of basic patterns (rectangular features) 9a to 9g of Haar-like features are defined. The Haar-like feature basic patterns 9a to 9g are respectively composed of a first region (region indicated by diagonal lines in one direction) r1 and a second region adjacent thereto (regions indicated by diagonal lines in two intersecting directions). ) R2. The Haar-like feature amount is a feature amount in the image, and a difference between the average luminance s (r1) of the first region r1 and the average luminance s (r2) of the second region r2 as in the following equation (1). It is obtained by taking The Haar-like feature amount is positive (+) if the luminance of the first region is relatively higher than the luminance of the second region, and is negative (-) if the luminance is relatively low.

h (r1, r2) = s (r1) −s (r2) (1)
　図２に、検出領域と矩形特徴との関係を示す。検出領域８とは撮影画像の任意の場所から切り出した領域で、判別器を用いて人物の顔があるか否かが判別される領域である。図２（ａ）の検出領域８では図１（ｄ）の矩形特徴９ｄが人物の両眼の位置に配置され、図２（ｂ）の検出領域では図１（ｇ）の矩形特長９ｇが人物の左眼及びその左上部分の位置に配置されている。 Fig. 2 shows the relationship between the detection area and the rectangular feature. The detection area 8 is an area cut out from an arbitrary place in the photographed image, and is an area where it is determined whether or not there is a human face using a discriminator. In the detection area 8 of FIG. 2A, the rectangular feature 9d of FIG. 1D is arranged at the position of both eyes of the person, and in the detection area of FIG. 2B, the rectangular feature 9g of FIG. The left eye and the upper left part thereof are arranged.
　検出領域８における各基本パターン（矩形特徴）９ａ～９ｇの位置と大きさを変化させることで、１つの検出領域８に対して、多数の矩形特徴９ａ～９ｇが用いられる。個々の矩形特徴９ａ～９ｇは、それぞれの特徴から得られるＨａａｒ－ｌｉｋｅ特徴量と閾値との比較により、この特徴に適しているか適していないかを判別する弱判別器を構成する。弱判別器は、自己の矩形特徴について撮影画像における顔上に置かれた位置とＨａａｒ－ｌｉｋｅ特徴量との関係を学習したデータベースを参照して判別する。顔検出は、各検出領域８に対して、異なる矩形特徴９ａ～９ｇを持つ複数の弱判別器から構成された強判別器１０ａ～１０Ｎを複数縦列に連結し（Ｃａｓｃａｄｅ）、連結された複数の強判別器１０ａ～１０Ｎによる順次判定に基づいて、当該領域が“顔”か“非顔”であるか（すなわち、当該領域に顔が有るかないか）判定する。 A large number of rectangular features 9a to 9g are used for one detection region 8 by changing the positions and sizes of the basic patterns (rectangular features) 9a to 9g in the detection region 8. Each of the rectangular features 9a to 9g constitutes a weak discriminator that discriminates whether or not the feature is suitable for this feature by comparing the Haar-like feature amount obtained from each feature with a threshold value. The weak discriminator discriminates its own rectangular feature by referring to a database in which the relationship between the position placed on the face in the captured image and the Haar-like feature quantity is learned. In face detection, strong discriminators 10a to 10N composed of a plurality of weak discriminators having different rectangular features 9a to 9g are connected in a plurality of columns (Cascade) for each detection region 8, and a plurality of connected Based on the sequential determination by the strong discriminators 10a to 10N, it is determined whether the area is “face” or “non-face” (that is, whether the area has a face).
［判別器の構成］
　図３に強判別器１０ａ～１０Ｎの連結構成（Ｃａｓｃａｄｅ）を示す。撮影画像における各検出領域８に対して、初段（最上位）の強判別器１０ａから順に“顔・非顔”の判別を行い、検出領域が強判別器１０ａで“非顔”と判別された場合は、以降の判別処理は行われずに、この検出領域８に対する処理を終了する。検出領域８が強判別器１０ａで“顔”と判別された場合には、次段の強判別器１０ｂに処理が引き継がれる。次々に後段（下位）に引き継がれて、全ての強判別器１０ａ～１０Ｎで“顔”と判定された場合、この検出領域８内に“顔候補”が含まれると判定し処理を終了する。顔検出は、撮影画像における検出領域８の位置をずらしながら、異なるサイズの検出領域８についても実行される。全ての検出領域８について顔検出が終了した後、“顔候補”が含まれると判定された検出領域８内に、“顔候補”が含まれると判定された（異なるサイズの）検出領域８がＭ個（例えば３個以上）ある場合、当該領域に顔があると判定し、全ての処理を終了する。 [Configuration of classifier]
FIG. 3 shows a connection configuration (Cascade) of the strong discriminators 10a to 10N. For each detection area 8 in the photographed image, “face / non-face” is determined in order from the first (top) strong discriminator 10a, and the detection area is determined as “non-face” by the strong discriminator 10a. In this case, the subsequent determination process is not performed, and the process for the detection area 8 is terminated. When the detection area 8 is determined to be “face” by the strong discriminator 10a, the processing is taken over by the next strong discriminator 10b. When succeeding one after another (lower order) and all the strong discriminators 10a to 10N determine “faces”, it is determined that “face candidates” are included in this detection area 8, and the process is terminated. Face detection is also performed for detection areas 8 of different sizes while shifting the position of the detection area 8 in the captured image. After the face detection is completed for all the detection areas 8, the detection areas 8 that are determined to include “face candidates” (of different sizes) are included in the detection areas 8 that are determined to include “face candidates”. When there are M (for example, three or more), it is determined that there is a face in the area, and all the processes are ended.
　また、強判別器１０ａ～１０Ｎを構成する弱判別器の数を、最上位の強判別器１０ａでは最も少なく、下位の強判別器に進むに従って多くすることで、各検出領域８における“非顔”の判別を高速に行うことができる。Ｈａａｒ－ｌｉｋｅ特徴９ａ～９ｇに基づく多数の矩形特徴から顔検出に有効な矩形特徴の選択や、強判別器１０ａ～１０Ｎ内の弱識別器の構成および強識別器の連結順序は、多数の顔画像と非顔画像を学習データとして用いた強化学習（Ｂｏｏｓｔｉｎｇ）により事前に決定する。 In addition, the number of weak classifiers constituting the strong classifiers 10a to 10N is the smallest in the strongest classifier 10a at the highest level, and is increased as the strong classifier in the lower level is advanced. "" Can be determined at high speed. Selection of a rectangular feature effective for face detection from a large number of rectangular features based on the Haar-like features 9a to 9g, the configuration of weak classifiers in the strong classifiers 10a to 10N, and the connection order of the strong classifiers can It is determined in advance by reinforcement learning (Boosting) using an image and a non-face image as learning data.
［顔検出防止］
　顔検出を防止するためには、顔検出の縦列連結構成において、強判別器１０ａ～１０Ｎのいずれかに“非顔”と判別させれば良い。すなわち、強判別器１０ａ～１０Ｎを構成する弱判別器において、顔画像に付加されたノイズがＨａａｒ－ｌｉｋｅ特徴量９ａ～９ｇを大きく変化させることで、弱判別器に誤判別を起こさせれば良い。そこで、強化学習（Ｂｏｏｓｔｉｎｇ）により選択された顔検出に有効な矩形特徴９ａ～９ｇを解析することで、顔面のどの部分を変更するのが適切か検討した。 [Face detection prevention]
In order to prevent face detection, any one of the strong discriminators 10a to 10N may be determined to be “non-face” in the face detection cascade connection configuration. That is, in the weak classifiers constituting the strong classifiers 10a to 10N, the noise added to the face image greatly changes the Haar-like feature quantities 9a to 9g, thereby causing the weak classifier to misclassify. . Therefore, by analyzing the rectangular features 9a to 9g effective for face detection selected by reinforcement learning (Boosting), it was examined which part of the face should be changed appropriately.
　具体的には、５０００枚の顔画像と３０００枚の非顔画像を用いた学習データに基づいて選択した矩形特徴９ａ～９ｇを、第１の領域ｒ１内の数値を＋１、第２の領域ｒ２内の数値を－１として、検出領域８上に足し合わせることで、検出領域８上に大きい値をとる正値・負値を持つ部分領域を示し、顔面内の輝度値変更による顔検出の影響が大きい箇所を特定した。 Specifically, the rectangular features 9a to 9g selected based on the learning data using 5000 face images and 3000 non-face images are set to a numerical value in the first area r1 of +1 and the second area r2. By subtracting -1 from the detection area 8 and adding it to the detection area 8, the detection area 8 shows a partial area having a positive or negative value, and the influence of face detection by changing the luminance value in the face Identified the location where is large.
［輝度値変更位置の検討］
　図４は，顔検出に成功した検出領域８に上述の部分領域を重ね合わせたものである。図４中の第１の重ね合わせ領域（一方向の斜線で示された領域）Ｒ１は絶対値が大きい正値を持つ部分領域（相対的に輝度が高い領域）、第２の重ね合わせ領域（交差する二方向の斜線で示された領域）Ｒ２は絶対値が大きい負値を持つ部分領域（相対的に輝度が低い領域）を示している。具体的には、部分領域の正値・負値が－１から１の範囲にあるように規格化し、最大値から最大値－Δの範囲にある正値の部分領域を第１の重合わせ領域Ｒ１，最小値から最小値＋Δの範囲にある負値の部分領域を第２の重ね合わせ領域Ｒ２で示している。図に示すように、第１の重合わせ領域Ｒ１は鼻筋および口の周辺に、第２の重ね合わせ領域Ｒ２は眼の周辺に集中しており、Δを大きくしていくと領域の面積が増えていくのが分かる。この分析結果にゴーグル状のウェアラブルデバイスに組み込み可能な領域を組み合わせて検討した結果、顔検出の影響が大きい位置が眼の周辺および鼻筋周辺であることが導かれた。 [Examination of brightness value change position]
FIG. 4 shows the above-described partial area superimposed on the detection area 8 in which face detection is successful. In FIG. 4, a first overlapping region (region indicated by diagonal lines in one direction) R1 is a partial region having a positive value having a large absolute value (region having relatively high luminance), and a second overlapping region ( R2 indicates a partial region (region with relatively low luminance) having a large absolute value and a negative value. Specifically, normalization is performed so that the positive / negative values of the partial area are in the range of −1 to 1, and the positive partial area in the range of the maximum value to the maximum value −Δ is the first overlapping area. A negative partial region in the range from R1, minimum value to minimum value + Δ is indicated by a second overlapping region R2. As shown in the figure, the first overlapping region R1 is concentrated around the nose and the mouth, and the second overlapping region R2 is concentrated around the eye. As Δ increases, the area of the region increases. I can see it going. As a result of combining this analysis result with a region that can be incorporated into a goggle-like wearable device, it was found that the position where the influence of face detection is large is around the eye and the nose.
　図５にＨａａｒ－ｌｉｋｅ特徴の加算結果を示す。図５（ａ）にポジティブなＨａａｒ－ｌｉｋｅ特徴の加算結果（正値を持つ部分領域のＨａａｒ－ｌｉｋｅ特徴量を加算して、絶対値が大きい領域（最大値～最大値－Δ）を抽出した図）を、図５（ｂ）にネガティブなＨａａｒ－ｌｉｋｅ特徴の加算結果（負値を持つ部分領域のＨａａｒ－ｌｉｋｅ特徴量を加算して、絶対値が大きい領域（最小値～最小値＋Δ）を抽出した図）を示す。指定されたステージ（強判別器の段数）までに評価される全てのＨａａｒ－ｌｉｋｅ特徴の分布を画像にプロットした。５０％グレーを中心とし、ポジティブな特徴を＋１、ネガティブな特徴を－１として加算した。 Fig. 5 shows the addition result of the Haar-like feature. Fig. 5 (a) shows the result of adding positive Haar-like features (adding Haar-like features for partial regions with positive values to extract regions with a large absolute value (maximum value-maximum value -Δ)) Fig. 5 (b) shows the result of addition of negative Haar-like features (addition of Haar-like features of partial regions having negative values to obtain a region having a large absolute value (minimum value to minimum value + Δ)) The figure which extracted). The distribution of all Haar-like features evaluated up to the specified stage (number of strong classifier stages) was plotted on the image. Centering on 50% gray, the positive features were added as +1 and the negative features were added as -1.
　図６にポジティブなＨａａｒ－ｌｉｋｅ特徴とネガティブなＨａａｒ－ｌｉｋｅ特徴との重ね合わせ結果を示す。取りうる最大値に対する表示比率をΔとし、それを閾値としてフィルタリングをした結果を、元画像に重ね合わせて表示した。ここでは、Δ＝１．０００の場合を示しており、全ての特徴（全ての正値又は負値を取るＨａａｒ－ｌｉｋｅ特徴）が表示されている。 FIG. 6 shows the result of superposition of the positive Haar-like feature and the negative Haar-like feature. The display ratio with respect to the maximum value that can be taken is Δ, and the result of filtering using that as a threshold is displayed superimposed on the original image. Here, the case of Δ = 1.000 is shown, and all features (Haar-like features that take all positive values or negative values) are displayed.
　図７にステージ数が１の時の特徴分布を示す。ステージ１は、１つ目の強判別器に含まれるＨａａｒ－ｌｉｋｅ特徴について重ねたものである。これらの特徴はおおざっぱな特徴が多く、速く判別を行なうのに適している。Δ値が大きい程、多くの特徴が重なり合っているため、輝度値変更により顔の特徴を破壊し易くなる。第２の重ね合わせ領域Ｒ２は、顔の輝度値が低い特徴を有する箇所であり、明るくすることで、特徴を破壊する。また、第１の重ね合わせ領域Ｒ１は、顔の輝度値が高い特徴を有する箇所であり、暗くすることで、特徴を破壊する。図７（ａ）はΔ＝０．４００、図７（ｂ）はΔ＝０．６００、図７（ｃ）はΔ＝０．８００、図７（ｄ）はΔ＝１．０００である。Δが大きくなるにつれて特徴の占める面積が増加している。図７（ｂ）～（ｄ）で、眼を覆う部分が第２の重ね合わせ領域Ｒ２になっており、図７（ｃ）～（ｄ）で眼の下側が第１の重ね合わせ領域Ｒ１になっており、図７（ｄ）で両眼の間に第１の重ね合わせ領域Ｒ１がある。 Fig. 7 shows the feature distribution when the number of stages is one. Stage 1 is an overlay of the Haar-like features included in the first strong classifier. These features have many rough features and are suitable for quick discrimination. As the Δ value is larger, many features are overlapped. Therefore, it becomes easier to destroy the facial features by changing the luminance value. The second overlapping region R2 is a portion having a feature with a low brightness value of the face, and destroys the feature by making it brighter. The first overlapping region R1 is a portion having a feature with a high face luminance value, and the feature is destroyed by darkening. 7 (a) is Δ = 0.400, FIG. 7 (b) is Δ = 0.600, FIG. 7 (c) is Δ = 0.800, and FIG. 7 (d) is Δ = 1.000. As Δ increases, the area occupied by the features increases. 7 (b) to (d), the portion covering the eye is the second overlapping region R2, and in FIGS. 7 (c) to (d), the lower side of the eye is the first overlapping region R1. In FIG. 7D, there is a first overlapping region R1 between both eyes.
　図８にステージ数が５の時の特徴分布を示す。ステージ５は、５つ目までの強判別器に含まれるＨａａｒ－ｌｉｋｅ特徴について重ねたものである。細かな特徴が含まれるようになっている。図８（ａ）はΔ＝０．８２５、図８（ｂ）はΔ＝０．８５０、図８（ｃ）はΔ＝０．８７５、図８（ｄ）はΔ＝０．９００である。Δが大きくなるにつれて特徴の占める面積が増加している。図８（ｃ）～（ｄ）で、眼を覆う部分が第２の重ね合わせ領域Ｒ２になっており、図８（ｃ）～（ｄ）で眼の下側が第１の重ね合わせ領域Ｒ１になっており、図８（ｄ）で両眼の間に第１の重ね合わせ領域Ｒ１がある。 Fig. 8 shows the feature distribution when the number of stages is five. Stage 5 is an overlay of Haar-like features included in up to five strong classifiers. Detailed features are included. 8A is Δ = 0.825, FIG. 8B is Δ = 0.850, FIG. 8C is Δ = 0.875, and FIG. 8D is Δ = 0.900. As Δ increases, the area occupied by the features increases. In FIGS. 8C to 8D, the portion covering the eye is the second overlapping region R2, and in FIGS. 8C to 8D, the lower side of the eye is the first overlapping region R1. In FIG. 8D, there is a first overlapping region R1 between both eyes.
　図９にステージ数が９の時の特徴分布を示す。ステージ９は、９つ目までの強判別器に含まれるＨａａｒ－ｌｉｋｅ特徴について重ねたものである。一層細かな特徴が含まれるようになっている。図９（ａ）はΔ＝０．８６０、図９（ｂ）はΔ＝０．８８０、図９（ｃ）はΔ＝０．８９０、図９（ｄ）はΔ＝０．９００である。Δが大きくなるにつれて特徴の占める面積が増加している。図９（ｂ）～（ｄ）で、眼を覆う部分が第２の重ね合わせ領域Ｒ２になっており、図９（ｄ）で眼の下側が第１の重ね合わせ領域Ｒ１になっており、図９（ｄ）で両眼の間に第１の重ね合わせ領域Ｒ１がある。 Fig. 9 shows the feature distribution when the number of stages is nine. Stage 9 is an overlay of Haar-like features included in up to nine strong classifiers. More detailed features are included. 9A shows Δ = 0.860, FIG. 9B shows Δ = 0.880, FIG. 9C shows Δ = 0.890, and FIG. 9D shows Δ = 0.900. As Δ increases, the area occupied by the features increases. In FIGS. 9B to 9D, the portion covering the eye is the second overlapping region R2, and in FIG. 9D, the lower side of the eye is the first overlapping region R1, In FIG. 9D, there is a first overlapping region R1 between both eyes.
　以上により、眼を覆う部分が輝度値が低く評価される部分になっており、眼の下側及び両眼の間が輝度値が高く評価される部分になっていることが解る。 From the above, it can be seen that the portion covering the eye is a portion where the luminance value is evaluated low, and the lower side of the eye and between the eyes are portions where the luminance value is evaluated high.
　実施例１に、眼鏡型の顔検出防止具であって、眼鏡レンズ全体が赤外線反射フィルターとして機能する例を示す。　 Example 1 shows an example of a spectacle-type face detection prevention device in which the entire spectacle lens functions as an infrared reflection filter. *
　図１０に実施例１における顔検出防止具１Ａ１の斜視図を示す。眼鏡型であり、部材としての眼鏡レンズ部３Ａを高輝度化部材としての赤外線反射フィルターとする例である。顔検出防止具１Ａ１は、可視光を透過し赤外線を反射する赤外線反射フィルター４Ａで構成された眼鏡レンズ部３Ａ、眼鏡レンズ部３Ａを人物の眼前に支持するフレーム部２Ａ、フレーム部２Ａを人物の顔に装着する装着部５Ａ（眼鏡のつる部に該当する）で構成される。眼鏡レンズ部３Ａは透明板（全部又は一部が半透明のものを含む）、例えばガラス又はプラスチックで構成される。装着部５Ａを人物の耳にかけることにより顔検出防止具１Ａ１が人物の顔に装着される。装着すると、眼鏡レンズ部３Ａは人物の顔の特定領域に対向するように配置される。ここで、人物の顔の特定領域に対向する位置とは、顔検出防止具を装着した時に、正面から見て、人物の顔の特定領域に重なる部材の部分である。正面から見て、人物の顔の特定領域を覆うように配置されるのが理想的であるが、必ずしも全部を覆うように配置される必要はなく、顔判別器の判定を誤らせるのに十分であれば良い（例えば、反射率や顔判別器の性能に依存するが、反射率が高ければ７０％以上覆えば良い等である）。本実施例では、特定領域が眼の場合であるが、部材としての眼鏡レンズ部３Ａは眼を覆うように人物の眼前に配置するものとする。 FIG. 10 is a perspective view of the face detection preventing tool 1A1 according to the first embodiment. It is an example of an eyeglass type, and the spectacle lens part 3A as a member is an infrared reflection filter as a high brightness member. The face detection preventive tool 1A1 includes a spectacle lens unit 3A composed of an infrared reflection filter 4A that transmits visible light and reflects infrared rays, a frame unit 2A that supports the spectacle lens unit 3A in front of a person's eyes, and a frame unit 2A It is composed of a mounting portion 5A (corresponding to a vine portion of glasses) that is mounted on the face. The spectacle lens unit 3A is made of a transparent plate (including all or a part of which is translucent), for example, glass or plastic. The face detection preventive tool 1A1 is attached to the face of the person by putting the attachment portion 5A on the person's ear. When worn, the spectacle lens unit 3A is arranged to face a specific area of the person's face. Here, the position facing the specific area of the person's face is a portion of a member that overlaps the specific area of the person's face when viewed from the front when the face detection prevention tool is worn. Ideally, it should be placed so as to cover a specific area of the person's face when viewed from the front, but it does not necessarily have to be placed so as to cover the whole area. (For example, it depends on the reflectance and the performance of the face discriminator, but if the reflectance is high, it is sufficient to cover 70% or more). In this embodiment, the specific region is the eye, but the spectacle lens unit 3A as a member is arranged in front of the human eye so as to cover the eye.
　人物が素顔でいる場合には、撮影画像において眼の部分は顔判別器により輝度が低く評価される。しかし、人物が顔検出防止具１Ａ１を装着すると、眼の部分が赤外線反射フィルター４Ａで覆われる。この状態で、赤外線反射フィルター４Ａは可視光を透過するので、人物は当該フィルターを通じて景色を見ることができる。他方で、眼鏡レンズ部３Ａが当該赤外線反射フィルター４Ａで構成された顔検出防止具１Ａ１を装着した人物が盗撮された場合、眼鏡レンズ部３Ａから赤外線が盗撮者のカメラに向かって反射される。カメラは赤外線に感光するので、撮影画像では人物の眼を覆う部分の輝度が高くなる。その結果、撮影画像がインターネット上に流出した場合でも、顔判別器は人物の顔を検出できなくなるという効果を奏する。又、光源を使用しないので、自然なコミュニケーションができる。
　以上により、自然なコミュニケーションとプライバシー保護を両立するような顔検出防止具を実現することができる。この効果は、以下の実施例についても同様にいえる。重複を避けるため、以下の実施例については説明を省略する。 When the person is a natural face, the brightness of the eye portion in the captured image is evaluated to be low by the face discriminator. However, when a person wears the face detection preventing tool 1A1, the eye portion is covered with the infrared reflection filter 4A. In this state, the infrared reflection filter 4A transmits visible light, so that a person can see the scenery through the filter. On the other hand, when a person wearing the face detection preventing tool 1A1 in which the spectacle lens unit 3A is configured by the infrared reflection filter 4A is voyeurized, infrared rays are reflected from the spectacle lens unit 3A toward the camera of the voyeur. Since the camera is sensitive to infrared rays, the brightness of the portion of the captured image that covers the human eye increases. As a result, the face discriminator has an effect that the face of the person cannot be detected even when the photographed image flows out on the Internet. Moreover, since no light source is used, natural communication is possible.
As described above, it is possible to realize a face detection preventing tool that achieves both natural communication and privacy protection. This effect can be similarly applied to the following embodiments. In order to avoid duplication, description of the following embodiments is omitted.
　眼鏡レンズ部３Ａに、赤外線反射フィルター４Ａの代わりに、赤色光反射フィルターを用いた場合でも、カメラは赤色光に感光して、顔判別器１１は人物の顔を検出できなくなるという効果を奏する。赤外線及び赤色光反射フィルターを用いた場合には、赤外線反射フィルターと赤色光反射フィルターの効果が加算されるので、より人の顔を検出し難くなる。
　このように、反射光として、赤外線の他に、赤色光、青色光、紫色光、紫外線を使用できる。ここで多種の光を用いる場合について触れる。赤外線と紫外線は人間の眼に感知されず、カメラに感光するので、これらを用いるのが好ましい。しかし、人間の眼は緑色の光に感じる割合が約７０％で最も大きいので、緑色光を透過すればさほど違和感はない。緑色光を透過し、赤外線等を反射する場合、入射する光のうち赤外線、赤色光、青色光、紫色光、紫外線のいずれかの全エネルギー量に対して反射するエネルギー量の割合が５０％以上、緑色光の全エネルギー量に対して透過するエネルギー量が５０％以上であれば良い。赤外線等を６０％以上反射し緑色光を６０％以上透過するのが好ましい。赤外線等を８０％以上反射し緑色光を８０％以上透過するのがさらに好ましい。また、可視光全体に対する緑色光の透過の割合が所定の値以上、例えば７５％以上が好ましく、８０％以上とするのがさらに好ましい。
　これらのことは、以下の実施例の赤外線反射フィルターについても同様にいえる。重複を避けるため、以下の実施例の赤外線反射フィルターについては説明を省略する。 Even when a red light reflection filter is used instead of the infrared reflection filter 4A for the spectacle lens unit 3A, the camera is sensitive to red light, and the face discriminator 11 cannot detect a human face. When the infrared and red light reflection filters are used, the effects of the infrared reflection filter and the red light reflection filter are added, so that it is more difficult to detect a human face.
As described above, red light, blue light, purple light, and ultraviolet light can be used as reflected light in addition to infrared light. Here, the case where various types of light are used will be described. Since infrared rays and ultraviolet rays are not perceived by human eyes but are sensitive to the camera, it is preferable to use them. However, the ratio of human eyes to green light is the largest at about 70%, so there is not much discomfort if green light is transmitted. When green light is transmitted and infrared light is reflected, the ratio of the amount of energy reflected to the total amount of any of infrared light, red light, blue light, violet light, and ultraviolet light is 50% or more. The amount of energy transmitted with respect to the total amount of green light may be 50% or more. It is preferable to reflect 60% or more of infrared rays and transmit 60% or more of green light. More preferably, 80% or more of infrared light is reflected and 80% or more of green light is transmitted. Further, the ratio of the transmission of green light to the entire visible light is preferably a predetermined value or more, for example, 75% or more, and more preferably 80% or more.
The same applies to the infrared reflective filters of the following examples. In order to avoid duplication, description is abbreviate | omitted about the infrared reflective filter of a following example.
　実施例２に、ゴーグル型の顔検出防止具であって、ゴーグル板全体が赤外線反射フィルターとして機能する例を示す。 Example 2 shows an example of a goggle-type face detection prevention device in which the entire goggle plate functions as an infrared reflection filter.
　図１１に実施例２における顔検出防止具１Ｂ１の斜視図を示す。ゴーグル型であり、部材としてのゴーグル板３Ｂ全体を高輝度化部材としての赤外線反射フィルター４Ｂとする例である。顔検出防止具１Ｂ１は、可視光を透過し赤外線を反射する赤外線反射フィルター４Ｂで構成されたゴーグル板３Ｂ、ゴーグル板３Ｂを人物の顔前に支持する支持部２Ｂ、支持部２Ｂを人物の顔に装着する装着部５Ｂ（眼鏡のつる部に該当する）で構成される。ゴーグル板３Ｂは透明板（全部又は一部が半透明のものを含む）、例えばガラス又はプラスチックで構成される。装着部５Ｂを人物の耳にかけることにより顔検出防止具１Ｂ１が人物の顔に装着される。装着すると、ゴーグル板３Ｂは人物の眼を覆うように人物の眼前に配置される。装着すると、ゴーグル板３Ｂは人物の顔の特定領域に対向するように人物の眼前に配置される。ここで、人物の顔の特定領域に対向する位置とは、顔検出防止具を装着した時に、正面から見て、人物の顔の特定領域に重なる部材の部分である。正面から見て、人物の顔の特定領域を覆うように配置されるのが理想的であるが、必ずしも全部を覆うように配置される必要はなく、顔判別器の判定を誤らせるのに十分であれば良い（例えば、反射率や顔判別器の性能に依存するが、反射率が高ければ７０％以上覆えば良い等である）。本実施例では、特定領域が眼の場合であるが、部材としてのゴーグル板３Ｂは眼を覆うように人物の眼前に配置するものとする。 FIG. 11 is a perspective view of the face detection preventing tool 1B1 according to the second embodiment. This is an example of the goggle type, and the entire goggle plate 3B as a member is an infrared reflection filter 4B as a high brightness member. The face detection preventive tool 1B1 includes a goggle plate 3B composed of an infrared reflection filter 4B that transmits visible light and reflects infrared rays, a support unit 2B that supports the goggle plate 3B in front of the person's face, and the support unit 2B that supports the person's face. It is comprised by the mounting part 5B (it corresponds to the vine part of spectacles) with which it mounts | wears. The goggle plate 3B is made of a transparent plate (including all or part of a translucent plate), for example, glass or plastic. The face detection preventing tool 1B1 is attached to the person's face by putting the attachment part 5B on the person's ear. When worn, the goggle board 3B is placed in front of the person's eyes so as to cover the person's eyes. When worn, the goggle board 3B is placed in front of the person's eyes so as to face a specific area of the person's face. Here, the position facing the specific area of the person's face is a portion of a member that overlaps the specific area of the person's face when viewed from the front when the face detection prevention tool is worn. Ideally, it should be placed so as to cover a specific area of the person's face when viewed from the front, but it does not necessarily have to be placed so as to cover the whole area. (For example, it depends on the reflectance and the performance of the face discriminator, but if the reflectance is high, it is sufficient to cover 70% or more). In this embodiment, the specific area is the eye, but the goggle plate 3B as a member is arranged in front of the person's eyes so as to cover the eyes.
　人物が素顔でいる場合には、撮影画像において眼の部分は顔判別器１１により輝度が低く評価される。しかし、人物が顔検出防止具１Ｂ１を装着すると、眼の部分が赤外線反射フィルター４Ｂで覆われる。この状態で、赤外線反射フィルター４Ｂは可視光を透過するので、人物は当該フィルターを通じて景色を見ることができる。他方で、ゴーグル板３Ｂが当該赤外線反射フィルター４Ｂで構成された顔検出防止具１Ｂ１を装着した人物が盗撮された場合、ゴーグル板３Ｂから赤外線が盗撮者のカメラに向かって反射される。カメラは赤外線に感光するので、撮影画像では人物の眼を覆う部分の輝度が高くなる。その結果、撮影画像がインターネット上に漏れ出た場合でも、顔判別器は人物の顔を検出できなくなるという効果を奏する。又、光源を使用しないので、自然なコミュニケーションができる。 When the person has a natural face, the face discriminator 11 evaluates the luminance of the eye portion to be low. However, when a person wears the face detection preventing tool 1B1, the eye portion is covered with the infrared reflection filter 4B. In this state, since the infrared reflection filter 4B transmits visible light, the person can see the scenery through the filter. On the other hand, when a person wearing the face detection preventing tool 1B1 having the goggle plate 3B composed of the infrared reflection filter 4B is voyeurized, infrared rays are reflected from the goggle plate 3B toward the camera of the voyeur. Since the camera is sensitive to infrared rays, the brightness of the portion of the captured image that covers the human eye increases. As a result, even if the captured image leaks on the Internet, the face discriminator has an effect that it cannot detect the face of the person. Moreover, since no light source is used, natural communication is possible.
　実施例３に、眼鏡型の顔検出防止具であって、眼鏡レンズの眼を覆う部分が赤外線反射フィルターとして機能する例を示す。ここでは、実施例１と異なる点を主として説明する。 Example 3 shows an example of a spectacle-type face detection prevention device in which a portion of an eyeglass lens covering the eye functions as an infrared reflection filter. Here, differences from the first embodiment will be mainly described.
　図１２に実施例３における顔検出防止具１Ａ２の斜視図を示す。実施例１では眼鏡レンズ部３Ａ全体が赤外線反射フィルターを構成するが、本実施例では部材としての眼鏡レンズ部３Ａの眼を覆う部分が赤外線反射フィルター４Ａを構成する。すなわち、眼鏡レンズ部３Ａの眼から離れた部分に透明のガラス又は透明のプラスチックで構成される部分３Ｇが存在する。
　この場合でも、顔検出防止具１Ａ２を装着すると、眼の部分は眼鏡レンズ部３Ａの赤外線反射フィルター４Ａを構成する領域で覆われるので、撮影画像において眼を覆う部分が顔判別器１１により輝度が高く評価される。その結果、撮影画像がインターネット上に流出した場合でも、顔判別器は人物の顔を検出できなくなるという効果を奏する。又、光源を使用しないので、自然なコミュニケーションができる。 FIG. 12 is a perspective view of the face detection preventing tool 1A2 according to the third embodiment. In Example 1, the spectacle lens unit 3A as a whole constitutes an infrared reflection filter, but in this example, a portion covering the eye of the spectacle lens unit 3A as a member constitutes an infrared reflection filter 4A. That is, there is a portion 3G made of transparent glass or transparent plastic in a portion away from the eye of the spectacle lens portion 3A.
Even in this case, when the face detection preventive tool 1A2 is attached, the eye part is covered with the region constituting the infrared reflection filter 4A of the spectacle lens unit 3A, so that the part that covers the eye in the photographed image has a luminance by the face discriminator 11. Highly appreciated. As a result, the face discriminator has an effect that the face of the person cannot be detected even when the photographed image flows out on the Internet. Moreover, since no light source is used, natural communication is possible.
　実施例４に、ゴーグル型の顔検出防止具であって、ゴーグルの眼を覆う部分が赤外線反射フィルターとして機能する例を示す。ここでは、実施例２と異なる点を主として説明する。 Example 4 shows an example of a goggle-type face detection prevention device in which a part of the goggles covering the eyes functions as an infrared reflection filter. Here, differences from the second embodiment will be mainly described.
　図１３に実施例４における顔検出防止具１Ｂ２の斜視図を示す。実施例２ではゴーグル板３Ｂ全体が赤外線反射フィルター４Ｂを構成するが、本実施例では部材としてのゴーグル板３Ｂのうちの眼を覆う部分が赤外線反射フィルター４Ｂを構成する。すなわち、ゴーグル板３Ｂの眼から離れた部分に透明のガラス又は透明のプラスチックで構成される部分３Ｇが存在する。
　この場合でも、顔検出防止具１Ｂ２を装着すると、眼の部分は眼鏡レンズ部３Ａの赤外線反射フィルター４Ｂを構成する領域で覆われるので、撮影画像において眼を覆う部分が顔判別器１１により輝度が高く評価される。その結果、撮影画像がインターネット上に流出した場合でも、顔判別器は人物の顔を検出できなくなるという効果を奏する。又、光源を使用しないので、自然なコミュニケーションができる。 FIG. 13 is a perspective view of the face detection preventing tool 1B2 according to the fourth embodiment. In the second embodiment, the entire goggle plate 3B constitutes the infrared reflection filter 4B. In this embodiment, the portion of the goggle plate 3B as a member that covers the eyes constitutes the infrared reflection filter 4B. That is, a part 3G made of transparent glass or transparent plastic exists in a part of the goggle plate 3B away from the eyes.
Even in this case, when the face detection preventing tool 1B2 is attached, the eye part is covered with the region constituting the infrared reflection filter 4B of the spectacle lens unit 3A. Highly appreciated. As a result, the face discriminator has an effect that the face of the person cannot be detected even when the photographed image flows out on the Internet. Moreover, since no light source is used, natural communication is possible.
　実施例５に、眼鏡型の顔検出防止具であって、赤外線反射フィルターの機能が眼鏡レンズ部の眼の中心部を覆う部分で最も強く、眼から遠い部分で０になるように徐々に変化する例を示す。ここでは、実施例３と異なる点を主として説明する。 Example 5 is a spectacle-type face detection preventing device according to Example 5, in which the function of the infrared reflection filter is the strongest in the part covering the center of the eye of the spectacle lens part and gradually changes to 0 in the part far from the eye. An example is shown. Here, differences from the third embodiment will be mainly described.
　図１４に実施例５における顔検出防止具１Ａ３の斜視図を示す。実施例３では眼鏡レンズ部３Ａの眼を覆う部分が赤外線反射フィルター４Ａを構成し、眼鏡レンズ部３Ａには赤外線反射フィルター４Ａの機能を有する部分と有さない部分との境界で反射率が急激に変化するが、本実施例では反射率が赤外線反射フィルター４Ａの機能を有する部分である眼の中心部から有さない部分に徐々に変化する。
　この場合でも、顔検出防止具１Ａ３を装着すると、眼の中心部は、部材としての眼鏡レンズ部３Ａのうちの赤外線反射フィルター４Ａの機能が比較的大きい領域で覆われるので、撮影画像において眼の中心部は顔判別器１１により輝度が高く評価される。その結果、撮影画像がインターネット上に流出した場合でも、顔判別器は人物の顔を検出できなくなるという効果を奏する。 FIG. 14 is a perspective view of the face detection preventing tool 1A3 according to the fifth embodiment. In Example 3, the portion of the spectacle lens portion 3A covering the eye constitutes the infrared reflection filter 4A, and the spectacle lens portion 3A has a sharp reflectance at the boundary between the portion having the function of the infrared reflection filter 4A and the portion not having it. However, in this embodiment, the reflectance gradually changes from the central part of the eye, which is the part having the function of the infrared reflection filter 4A, to the part not having the function.
Even in this case, when the face detection preventing tool 1A3 is attached, the center of the eye is covered with a region where the function of the infrared reflection filter 4A in the spectacle lens unit 3A as a member is relatively large. The central part is highly evaluated by the face discriminator 11. As a result, the face discriminator has an effect that the face of the person cannot be detected even when the photographed image flows out on the Internet.
　実施例６に、ゴーグル型の顔検出防止具であって、赤外線反射フィルターの機能がゴーグル板の眼を覆う部分で最も強く、遠方部分で０になるように徐々に変化する例を示す。ここでは、実施例４と異なる点を主として説明する。 Example 6 shows an example of a goggle-type face detection preventive device in which the function of the infrared reflection filter is the strongest in the part covering the eyes of the goggle plate and gradually changes to 0 in the far part. Here, differences from the fourth embodiment will be mainly described.
　図１５に実施例６における顔検出防止具１Ｂ３の斜視図を示す。実施例４ではゴーグル板３Ｂの眼を覆う部分が赤外線反射フィルター４Ｂを構成し、ゴーグル板３Ｂには赤外線反射フィルター４Ｂの機能を有する部分と有さない部分との間で反射率が急激に変化するが、本実施例では反射率が赤外線反射フィルター４Ｂの機能を有する部分である眼の中心部から有さない部分に徐々に変化する。
　この場合でも、顔検出防止具１Ｂ３を装着すると、眼の中心部は部材としてのゴーグル板３Ｂのうちの赤外線反射フィルター４Ｂの機能が比較的大きい領域で覆われるので、撮影画像において眼の中心部は顔判別器１１により輝度が高く評価される。その結果、撮影画像がインターネット上に流出した場合でも、顔判別器は人物の顔を検出できなくなるという効果を奏する。 FIG. 15 is a perspective view of the face detection preventing tool 1B3 according to the sixth embodiment. In Example 4, the part of the goggle plate 3B covering the eyes constitutes the infrared reflection filter 4B, and the reflectance changes rapidly between the part having the function of the infrared reflection filter 4B and the part having no function of the goggle plate 3B. However, in this embodiment, the reflectance gradually changes from the central part of the eye, which is the part having the function of the infrared reflection filter 4B, to the part not having the function.
Even in this case, when the face detection preventing tool 1B3 is mounted, the center of the eye is covered with a region having a relatively large function of the infrared reflection filter 4B of the goggle plate 3B as a member. Is highly evaluated by the face discriminator 11. As a result, the face discriminator has an effect that the face of the person cannot be detected even when the photographed image flows out on the Internet.
　実施例７に、眼鏡型の顔検出防止具であって、赤外線反射フィルターが眼鏡レンズ部にモザイク状に配置されている例を示す。ここでは、実施例１と異なる点を主として説明する。 Example 7 shows an example of a spectacle-type face detection prevention device in which infrared reflection filters are arranged in a mosaic pattern on the spectacle lens unit. Here, differences from the first embodiment will be mainly described.
　図１６に実施例７における顔検出防止具１Ａ４の斜視図を示す。実施例１では眼鏡レンズ部３Ａ全体が赤外線反射フィルター４Ａを構成するが、本実施例では赤外線反射フィルター４Ａが部材としての眼鏡レンズ部３Ａにモザイク状に配置されている。眼鏡レンズ部３Ａにモザイク状に配置されているので、モザイク部分が眼を完全に覆うとは限らないが、モザイク片の数が多いので眼の多くの部分を覆う（例えば７０％以上を覆う）。撮影画像においてモザイク片で覆われた眼の部分が顔判別器１１により輝度が高く評価される。モザイク片は多数存在するので、輝度が高く評価される部分が多く、積算されると大きな値になり、その結果、撮影画像がインターネット上に流出した場合でも、顔判別器は人物の顔を検出できなくなるという効果を奏する。 FIG. 16 shows a perspective view of the face detection preventing tool 1A4 according to the seventh embodiment. In Example 1, the spectacle lens unit 3A as a whole constitutes the infrared reflection filter 4A. In this example, the infrared reflection filter 4A is arranged in a mosaic pattern on the spectacle lens unit 3A as a member. Since the eyeglass lens unit 3A is arranged in a mosaic shape, the mosaic part does not necessarily completely cover the eyes, but covers many parts of the eye (for example, covers 70% or more) because the number of mosaic pieces is large. . The portion of the eye covered with the mosaic piece in the captured image is highly evaluated by the face discriminator 11. Since there are many mosaic pieces, there are many parts that are highly evaluated for brightness, and when integrated, the value becomes large, and as a result, the face discriminator detects the face of a person even if the shot image leaks onto the Internet There is an effect that it becomes impossible.
　実施例８に、ゴーグル型の顔検出防止具であって、赤外線反射フィルターがゴーグル板にモザイク状に配置されている例を示す。ここでは、実施例２と異なる点を主として説明する。 Example 8 shows an example of a goggle-type face detection prevention device in which infrared reflection filters are arranged in a mosaic on a goggle plate. Here, differences from the second embodiment will be mainly described.
　図１７に実施例８における顔検出防止具１Ｂ４の斜視図を示す。実施例２ではゴーグル板３Ｂ全体が赤外線反射フィルター４Ｂを構成するが、本実施例では赤外線反射フィルター４Ｂが部材としてのゴーグル板３Ｂにモザイク状に配置されている。ゴーグル板３Ｂにモザイク状に配置されているので、モザイク部分が眼を完全に覆うとは限らないが、モザイク片の数が多いので眼の多くの部分を覆う（例えば７０％以上を覆う）。撮影画像においてモザイク片で覆われた眼の部分が顔判別器１１により輝度が高く評価される。モザイク片は多数存在するので、輝度が高く評価される部分が多く、積算されると大きな値になり、その結果、撮影画像がインターネット上に流出した場合でも、顔判別器は人物の顔を検出できなくなるという効果を奏する。 FIG. 17 shows a perspective view of the face detection preventing tool 1B4 according to the eighth embodiment. In the second embodiment, the entire goggle plate 3B constitutes the infrared reflection filter 4B. In this embodiment, the infrared reflection filter 4B is arranged in a mosaic pattern on the goggle plate 3B as a member. Since the goggle plate 3B is arranged in a mosaic shape, the mosaic portion does not necessarily completely cover the eye, but covers many portions of the eye (for example, covers 70% or more) because the number of mosaic pieces is large. The portion of the eye covered with the mosaic piece in the captured image is highly evaluated by the face discriminator 11. Since there are many mosaic pieces, there are many parts that are highly evaluated for brightness, and when integrated, the value becomes large, and as a result, the face discriminator detects the face of a person even if the shot image leaks onto the Internet There is an effect that it becomes impossible.
　実施例９に、ゴーグル型の顔検出防止具であって、ゴーグル全体が赤外線吸収フィルターとして機能する例を示す。ここでは、実施例２と異なる点を主として説明する。 Example 9 shows an example of a goggle-type face detection prevention device in which the entire goggle functions as an infrared absorption filter. Here, differences from the second embodiment will be mainly described.
　図１８に実施例９における顔検出防止具１Ｂ５の斜視図を示す。実施例２ではゴーグル板３Ｂ全体が赤外線反射フィルター４Ｂを構成するが、本実施例ではゴーグル板３Ｂ全体が赤外線吸収フィルター４Ｂ０を構成する。
　この場合、顔検出防止具１Ｂ５を装着すると、鼻筋の大部分が部材としてのゴーグル板３Ｂの赤外線吸収フィルター４Ｂ０を構成する領域で覆われるので、カメラにおける赤外線の感光が弱まり、撮影画像において鼻筋の部分は顔判別器１１により輝度が低く評価される。鼻筋の全部が覆われるのが理想的であるが、大部分（７０％以上）が覆われれば良い。その結果、撮影画像がインターネット上に流出した場合でも、顔判別器は人物の顔を検出できなくなるという効果を奏する。 FIG. 18 is a perspective view of the face detection preventing tool 1B5 according to the ninth embodiment. In the second embodiment, the entire goggle plate 3B constitutes the infrared reflection filter 4B. In the present embodiment, the entire goggles plate 3B constitutes the infrared absorption filter 4B0.
In this case, when the face detection preventive tool 1B5 is mounted, most of the nose muscles are covered with the region constituting the infrared absorption filter 4B0 of the goggle plate 3B as a member. The brightness of the portion is evaluated to be low by the face discriminator 11. Ideally, the entire nose is covered, but the majority (70% or more) should be covered. As a result, the face discriminator has an effect that the face of the person cannot be detected even when the photographed image flows out on the Internet.
　ゴーグル板３Ｂに、赤外線吸収フィルター４Ｂ０の代わりに、赤色光吸収フィルターを用いた場合でも、カメラにおける赤色光の感光が弱まるので、顔判別器１１は人物の顔を検出できなくなるという効果を奏する。赤外線吸収フィルター及び赤色光吸収フィルターを用いた場合には、赤外線吸収フィルターと赤色光吸収フィルターの効果が加算されるので、より人の顔を検出し難くなる。このことは、以下の実施例の赤外線吸収フィルターについても同様にいえる。重複を避けるため、以下の実施例の赤外線吸収フィルターについては説明を省略する。 Even when a red light absorption filter is used instead of the infrared absorption filter 4B0 for the goggle plate 3B, the sensitivity of the red light in the camera is weakened, so that the face discriminator 11 has an effect that the face of the person cannot be detected. When the infrared absorption filter and the red light absorption filter are used, the effects of the infrared absorption filter and the red light absorption filter are added, so that it is more difficult to detect a human face. The same applies to the infrared absorption filters of the following examples. In order to avoid duplication, description of the infrared absorption filters of the following examples is omitted.
　実施例１０に、ゴーグル型の顔検出防止具であって、ゴーグルの鼻筋を覆う部分（上半分でも良い）が赤外線吸収フィルターとして機能する例を示す。ここでは、実施例９と異なる点を主として説明する。 Example 10 shows an example of a goggle-type face detection prevention device in which a part (or upper half of the goggle) covering the nose muscles functions as an infrared absorption filter. Here, differences from the ninth embodiment will be mainly described.
　図１９に実施例１０における顔検出防止具１Ｂ６の斜視図を示す。実施例９ではゴーグル板３Ｂ全体が赤外線吸収フィルター４Ｂ０を構成するが、本実施例ではゴーグル板３Ｂの鼻筋を覆う部分が赤外線反射フィルター４Ｂ０を構成する。すなわち、ゴーグル板３Ｂの鼻から離れた部分に透明のガラス又は透明のプラスチックで構成される部分３Ｇが存在する。
　この場合でも、顔検出防止具１Ｂ６を装着すると、鼻筋の大部分が部材としてのゴーグル板３Ｂの赤外線吸収フィルター４Ｂ０を構成する領域で覆われるので、カメラにおける赤外線の感光が弱まり、撮影画像において鼻筋の部分は顔判別器１１により輝度が低く評価される。鼻筋の全部が覆われるのが理想的であるが、大部分（７０％以上）が覆われれば良い。その結果、撮影画像がインターネット上に流出した場合でも、顔判別器は人物の顔を検出できなくなるという効果を奏する。 FIG. 19 is a perspective view of the face detection preventing tool 1B6 according to the tenth embodiment. In the ninth embodiment, the entire goggle plate 3B constitutes the infrared absorption filter 4B0. In this embodiment, the portion of the goggle plate 3B that covers the nose muscles constitutes the infrared reflection filter 4B0. That is, a part 3G made of transparent glass or transparent plastic exists in a part away from the nose of the goggle plate 3B.
Even in this case, when the face detection preventing device 1B6 is worn, most of the nose muscles are covered with the region constituting the infrared absorption filter 4B0 of the goggle plate 3B as a member. The portion is evaluated with low brightness by the face discriminator 11. Ideally, the entire nose is covered, but the majority (70% or more) should be covered. As a result, the face discriminator has an effect that the face of the person cannot be detected even when the photographed image flows out on the Internet.
　実施例１１に、眼鏡型の顔検出防止具であって、眼鏡レンズ部に赤外線反射フィルターと赤外線吸収フィルターとを共に用いる例を示す。ここでは、実施例１と異なる点を主として説明する。 Example 11 shows an example of a spectacle-type face detection prevention device that uses both an infrared reflection filter and an infrared absorption filter for the spectacle lens unit. Here, differences from the first embodiment will be mainly described.
　図２０に実施例１１における顔検出防止具１Ａ７の斜視図を示す。実施例１では眼鏡レンズ部３Ａ全体が赤外線反射フィルター４Ａを構成するが、本実施例では部材としての眼鏡レンズ部３Ａの両眼を覆う部分が赤外線反射フィルター４Ａ１を構成し、その下側の部分が赤外線吸収フィルター４Ａ２を構成する。特徴分布に関する図によれば（図７（ｄ）、図８（ｄ）、図９（ｄ）　参照）、眼を覆う部分は輝度値が低い特徴を持つ箇所、その下側の部分及び両目の間の部分が輝度値が高い（明るい）特徴を持つ部分になっている。したがって、眼鏡レンズ部３Ａの眼を覆う部分に対応する位置に赤外線反射フィルター４Ａ１を、その下側の部分に対応する位置に赤外線吸収フィルター４Ａ２を配置すれば、実施例１に比して、一層顔判別器１１の判別を困難にすることになる。その結果、撮影画像がインターネット上に流出した場合でも、顔判別器は人物の顔を検出できなくなるという効果を奏する。 FIG. 20 shows a perspective view of the face detection preventive tool 1A7 in the eleventh embodiment. In the first embodiment, the entire spectacle lens portion 3A constitutes the infrared reflection filter 4A. In this embodiment, the portion covering both eyes of the spectacle lens portion 3A as a member constitutes the infrared reflection filter 4A1, and the lower portion thereof. Constitutes the infrared absorption filter 4A2. According to the feature distribution diagrams (see FIGS. 7 (d), 8 (d), and 9 (d)), the portion covering the eye has a feature with a low luminance value, its lower portion, and both eyes The part in between is a part having a high (bright) luminance value. Therefore, if the infrared reflection filter 4A1 is disposed at a position corresponding to the portion covering the eye of the spectacle lens unit 3A, and the infrared absorption filter 4A2 is disposed at a position corresponding to the lower portion thereof, compared with the first embodiment. This makes it difficult for the face discriminator 11 to discriminate. As a result, the face discriminator has an effect that the face of the person cannot be detected even when the photographed image flows out on the Internet.
　実施例１２に、ゴーグル型の顔検出防止具であって、赤外線反射フィルターと赤外線吸収フィルターとを共に用いる例を示す。ここでは、実施例２及び実施例９と異なる点を主として説明する。 Example 12 is an example of a goggle-type face detection prevention device that uses both an infrared reflection filter and an infrared absorption filter. Here, differences from the second embodiment and the ninth embodiment will be mainly described.
　図２１に実施例１２における顔検出防止具１Ｂ７の斜視図を示す。実施例２ではゴーグル板３Ｂ全体が赤外線反射フィルター４Ｂを構成し、実施例９ではゴーグル板３Ｂ全体が赤外線吸収フィルター４Ｂ０を構成するが、本実施例では部材としてのゴーグル板３Ｂの眼を覆う部分が赤外線反射フィルター４Ｂ１を構成し、その下側の部分及び両眼の間の部分が赤外線吸収フィルター４Ｂ２を構成する。前述の特徴分布に関する図に対応して、ゴーグル板３Ｂの眼を覆う部分に対応する位置に赤外線反射フィルター４Ｂ１を、その下側の部分及び両眼の間の部分に対応する位置に赤外線吸収フィルター４Ｂ２を配置すれば、実施例１に比して、一層顔判別器１１の判別を困難にすることになる。その結果、撮影画像がインターネット上に流出した場合でも、顔判別器は人物の顔を検出できなくなるという効果を奏する。 FIG. 21 shows a perspective view of the face detection preventing tool 1B7 in the twelfth embodiment. In Example 2, the entire goggle plate 3B constitutes the infrared reflection filter 4B, and in Example 9, the entire goggle plate 3B constitutes the infrared absorption filter 4B0, but in this example, the portion of the goggle plate 3B as a member that covers the eyes Constitutes the infrared reflection filter 4B1, and the lower part and the part between the eyes constitute the infrared absorption filter 4B2. Corresponding to the figure relating to the feature distribution described above, the infrared reflection filter 4B1 is disposed at a position corresponding to the portion covering the eye of the goggle plate 3B, and the infrared absorption filter is disposed at a position corresponding to the lower portion and the portion between both eyes. If 4B2 is arranged, the discrimination of the face discriminator 11 becomes more difficult as compared with the first embodiment. As a result, the face discriminator has an effect that the face of the person cannot be detected even when the photographed image flows out on the Internet.
　実施例１３に、眼鏡型の顔検出防止具であって、眼鏡レンズ部に反射率の異なる２種の赤外線反射フィルターを用いる例を示す。ここでは、実施例３と異なる点を主として説明する。 Example 13 shows an example of a spectacle-type face detection preventing device using two types of infrared reflection filters having different reflectivities in the spectacle lens unit. Here, differences from the third embodiment will be mainly described.
　図２２に実施例１３における顔検出防止具１Ａ８の斜視図を示す。実施例３（図１２参照）では眼鏡レンズ部３Ａの眼を覆う部分が赤外線反射フィルター４Ａを構成し、眼鏡レンズ部３Ａには赤外線反射フィルターの機能を有する部分４Ａと有さない部分３Ｇがあるが、本実施例では部材としての眼鏡レンズ部３Ａは、赤外線反射フィルターの機能を強く有する部分４Ａ３、有さない部分３Ｇ及び中間の部分４Ａ４を有する。すなわち、赤外線反射フィルターの反射率が２レベルある。本実施例では眼鏡レンズ部３Ａの眼を覆う部分が反射機能の高い赤外線反射フィルター４Ａ３を、その両眼の間に近い部分が反射機能の低い赤外線反射フィルター４Ａ４を構成し、これらの下側の部分が透明部分３Ｇを構成している。前述の特徴分布に関する図によれば、眼を覆う部分は輝度値が低い特徴を持つ箇所、その両眼の間に近い部分が輝度値が少し低い特徴を持つ箇所（低い特徴を持つ部分と高い特徴を持つ部分が重なっている）、これらの下側の部分は輝度値が高い（明るい）特徴を持つ部分になっている。したがって、眼鏡レンズ部３Ａの眼を覆う部分に対応する位置に反射機能の高い赤外線反射フィルター４Ａ３を、その両眼の間に近い部分に対応する位置に反射機能の低い赤外線反射フィルター４Ａ４を、これらの下側の部分に対応する位置に透明部分３Ｇを配置すれば、実施例１１に比して幾分劣るものの、顔判別器１１の判別を困難にすることになる。その結果、撮影画像がインターネット上に流出した場合でも、顔判別器は人物の顔を検出できなくなるという効果を奏する。 FIG. 22 is a perspective view of the face detection preventing tool 1A8 according to the thirteenth embodiment. In Example 3 (see FIG. 12), the portion of the spectacle lens portion 3A that covers the eyes constitutes the infrared reflection filter 4A, and the spectacle lens portion 3A has a portion 4A that has the function of an infrared reflection filter and a portion 3G that does not have it. However, in this embodiment, the spectacle lens portion 3A as a member has a portion 4A3 having a strong function of an infrared reflection filter, a portion 3G not having it, and an intermediate portion 4A4. That is, the reflectance of the infrared reflection filter is two levels. In the present embodiment, the portion of the eyeglass lens portion 3A covering the eye constitutes an infrared reflection filter 4A3 having a high reflection function, and the portion between both eyes constitutes an infrared reflection filter 4A4 having a low reflection function. The portion constitutes a transparent portion 3G. According to the above feature distribution diagram, the part covering the eye has a feature with a low luminance value, and the part between the eyes has a feature with a little low luminance value (a part with a low feature and a high value). The parts having features overlap), and the lower part thereof has a high brightness value (bright). Accordingly, the infrared reflection filter 4A3 having a high reflection function is provided at a position corresponding to a portion covering the eye of the spectacle lens unit 3A, and the infrared reflection filter 4A4 having a low reflection function is provided at a position corresponding to a portion close to both eyes. If the transparent portion 3G is arranged at a position corresponding to the lower portion of the image, it is difficult to discriminate the face discriminator 11 although it is somewhat inferior to the eleventh embodiment. As a result, the face discriminator has an effect that the face of the person cannot be detected even when the photographed image flows out on the Internet.
　実施例１４に、ゴーグル型の顔検出防止具であって、反射率の異なる２種の赤外線反射フィルターを用いる例を示す。ここでは、実施例４と異なる点を主として説明する。 Example 14 shows an example in which two types of infrared reflection filters that are goggles-type face detection preventing devices having different reflectivities are used. Here, differences from the fourth embodiment will be mainly described.
　図２３に実施例１４における顔検出防止具１Ｂ８の斜視図を示す。実施例４（図１３参照）ではゴーグル板３Ｂの眼を覆う部分が赤外線反射フィルター４Ｂを構成し、ゴーグル板３Ｂには赤外線反射フィルターの機能を有する部分４Ｂと有さない部分３Ｇがあるが、本実施例では部材としてのゴーグル板３Ｂは赤外線反射フィルターの機能を強く有する部分４Ｂ３、有さない部分３Ｇ及び中間の部分４Ｂ４を有する。すなわち、赤外線反射フィルターの反射率が２レベルある。本実施例ではゴーグル板３Ｂの眼を覆う部分が反射機能の高い赤外線反射フィルター４Ｂ３を、その両眼の間に近い部分が反射機能の低い赤外線反射フィルター４Ｂ４構成し、これらの下側の部分が透明部分３Ｇを構成している。前述の特徴分布に関する図に対応して、ゴーグル板３Ｂの眼を覆う部分に対応する位置に反射機能の高い赤外線反射フィルター４Ｂ３を、その両眼の間に近い部分に対応する位置に反射機能の低い赤外線反射フィルター４Ｂ４を、これらの下側の部分に対応する位置に透明部分３Ｇを配置すれば、実施例１２に比して幾分劣るものの、顔判別器１１の判別を困難にすることになる。その結果、撮影画像がインターネット上に流出した場合でも、顔判別器は人物の顔を検出できなくなるという効果を奏する。 FIG. 23 is a perspective view of the face detection preventing tool 1B8 according to the fourteenth embodiment. In Example 4 (see FIG. 13), the portion of the goggle plate 3B that covers the eyes constitutes the infrared reflection filter 4B, and the goggle plate 3B has a portion 4B that has the function of the infrared reflection filter and a portion 3G that does not have it. In this embodiment, the goggle plate 3B as a member has a portion 4B3 having a strong function of an infrared reflection filter, a portion 3G not having it, and an intermediate portion 4B4. That is, the reflectance of the infrared reflection filter is two levels. In the present embodiment, the portion of the goggle plate 3B covering the eyes constitutes the infrared reflection filter 4B3 having a high reflection function, the portion close to both eyes constitutes the infrared reflection filter 4B4 having a low reflection function, and the lower portion thereof is formed. The transparent portion 3G is configured. Corresponding to the figure relating to the feature distribution described above, the infrared reflection filter 4B3 having a high reflection function is provided at a position corresponding to the portion covering the eyes of the goggle plate 3B, and the reflection function is provided at a position corresponding to a portion between the eyes. If the low infrared reflection filter 4B4 is provided with the transparent portion 3G at a position corresponding to the lower portion of the filter, it is difficult to discriminate the face discriminator 11 although it is somewhat inferior to the twelfth embodiment. Become. As a result, the face discriminator has an effect that the face of the person cannot be detected even when the photographed image flows out on the Internet.
　実施例１５に、眼鏡型の顔検出防止具であって、眼鏡レンズ部に特徴分布に応じてコンピュータで赤外線反射フィルターと赤外線吸収フィルターとを自動配置する例を示す。ここでは、実施例１１と異なる点を主として説明する。 Example 15 shows an example of a spectacle-type face detection prevention device in which an infrared reflection filter and an infrared absorption filter are automatically arranged on a spectacle lens unit by a computer according to a feature distribution. Here, differences from the eleventh embodiment will be mainly described.
　図２４に実施例１５における顔検出防止具１Ａ９の斜視図を示す。実施例１１（図２０参照）では眼鏡レンズ部３Ａの眼を覆う部分が赤外線反射フィルター４Ａ１を構成し、その下側の部分が赤外線吸収フィルター４Ａ２を構成しているが、本実施例では部材としての眼鏡レンズ部３Ａに赤外線反射フィルター４Ａ１を構成する部分と赤外線吸収フィルター４Ａ２を構成する部分をコンピュータで自動的に配置する。 FIG. 24 is a perspective view of the face detection preventing tool 1A9 according to the fifteenth embodiment. In Example 11 (see FIG. 20), the part covering the eye of the spectacle lens part 3A constitutes the infrared reflection filter 4A1, and the lower part constitutes the infrared absorption filter 4A2, but in this example, as a member A portion constituting the infrared reflection filter 4A1 and a portion constituting the infrared absorption filter 4A2 are automatically arranged in the eyeglass lens portion 3A by a computer.
　人物の顔を検出する顔判別器１１を用いて、検出領域８において輝度が低く評価される人物の顔の位置、及び、検出領域８において輝度が高く評価される人物の顔の位置を求め、コンピュータの記憶部に記憶する。そして、コンピュータを用いて、記憶部から、検出領域において輝度が低く評価される人物の顔の位置を読み出して、眼鏡レンズ部３Ａ上に、高輝度化部材としての赤外線反射フィルター４Ａ１を配置し、輝度が高く評価される人物の顔の位置を読み出して低輝度化部材としての赤外線吸収フィルター４Ａ２を配置する。赤外線反射フィルター４Ａ１及び赤外線吸収フィルター４Ａ２が配置されない部分は透明部分３Ｇとなる。
　輝度が低く評価される人物の顔の位置に赤外線反射フィルター４Ａ１を、輝度が高く評価される人物の顔の位置に赤外線吸収フィルター４Ａ２を配置することにより、両者共に顔判別器１１の判別を困難にする方向に変化するので、その結果、撮影画像がインターネット上に流出した場合でも、顔判別器は人物の顔を検出できなくなるという効果を奏する。 Using the face discriminator 11 that detects the face of a person, the position of the face of the person whose luminance is evaluated to be low in the detection area 8 and the position of the face of the person whose brightness is evaluated to be high in the detection area 8 are determined. It memorize | stores in the memory | storage part of a computer. Then, using a computer, the position of the face of the person whose luminance is evaluated to be low in the detection area is read from the storage unit, and the infrared reflection filter 4A1 as a high luminance member is disposed on the spectacle lens unit 3A. The position of the face of the person whose luminance is highly evaluated is read out, and an infrared absorption filter 4A2 is arranged as a low luminance reducing member. A portion where the infrared reflection filter 4A1 and the infrared absorption filter 4A2 are not arranged becomes a transparent portion 3G.
By disposing the infrared reflection filter 4A1 at the position of the face of the person whose luminance is evaluated to be low and the infrared absorption filter 4A2 at the position of the face of the person who evaluates the brightness as high, it is difficult for the face discriminator 11 to discriminate both. As a result, the face discriminator cannot detect the face of the person even if the photographed image flows out on the Internet.
　図２５に実施例１５における顔検出防止具１Ａ９の製造方法を示す。図２５における「及び（／又は）」との表現は、本実施例では「及び」で良いが、変形例として「又は」が適用できるパターンもあり得るので、かかる表現にした。
　まず、顔検出防止具１Ａ９の部材３Ａを形成するための原料と透明基板を準備する。部材３Ａは、人物の顔に装着されて、カメラで撮影された撮影画像の検出領域８の輝度の評価を通して、撮影画像の中から人物の顔を検出する顔判別器１１の輝度の評価を変更させる顔検出防止具１Ａ９の部材３Ａで、人物の顔の特定領域に対向するように配置される部材である。部材のうち、特定領域としての、検出領域８において輝度が低く評価される人物の顔の位置に配置され、輝度を高く変化させる高輝度化部材の原料、及び（／又は）、特定領域としての、検出領域８において輝度が高く評価される人物の顔の位置に配置され、輝度を低く変化させる低輝度化部材の原料、及び原料を搭載するための透明基板を準備する（Ｓ００１）。原料として例えば塗料を用いる。 FIG. 25 shows a method for manufacturing the face detection preventing tool 1A9 according to the fifteenth embodiment. The expression “and (or)” in FIG. 25 may be “and” in the present embodiment, but there is a pattern to which “or” can be applied as a modified example, so this expression is used.
First, a raw material and a transparent substrate for forming the member 3A of the face detection preventing tool 1A9 are prepared. The member 3A is attached to a person's face and changes the evaluation of the brightness of the face discriminator 11 that detects the person's face from the photographed image through the evaluation of the brightness of the detection area 8 of the photographed image taken by the camera. The member 3A of the face detection preventive tool 1A9 to be arranged is a member arranged to face a specific region of the person's face. Among the members, the raw material of the high-brightness member that is arranged at the position of the face of the person whose luminance is evaluated to be low in the detection region 8 as the specific region and changes the luminance high, and / or the specific region In the detection area 8, a raw material for a low-brightness reducing member that is arranged at the position of the face of the person whose luminance is highly evaluated and changes the luminance low, and a transparent substrate for mounting the raw material are prepared (S001). For example, a paint is used as the raw material.
　次に、顔検出防止具を未着用の撮影画像について、顔判別器１１を用いて輝度が低く及び（／又は）輝度が高く評価される人物の顔の位置を求めて記憶する。すなわち、カメラで撮影された撮影画像の検出領域８の輝度の評価を通して、撮影画像の中から人物の顔を検出する顔判別器１１であって、検出領域８に対して異なる矩形特徴９ａ～９ｇを有し、Ｈａａｒ－ｌｉｋｅ特徴量を用いて検出領域８の輝度を評価する複数の弱判別器から構成された強判別器１０ａ～１０Ｎを複数連結して構成された顔判別器１１を使用する（図３参照）。顔判別器１１は連結された複数の強判別器１０ａ～１０Ｎによる順次判定に基づいて、検出領域８に顔があるか否かを判定することにより、人物の顔を検出する。かかる顔判別器１１を用いて、特定領域としての、検出領域８において輝度が低く評価される人物の顔の位置、及び（／又は）、特定領域としての、検出領域８において輝度が高く評価される人物の顔の位置を求め、コンピュータの記憶部に記憶する（Ｓ００２）。 Next, with respect to a photographed image in which the face detection prevention tool is not worn, the face discriminator 11 is used to determine and store the position of the face of the person whose luminance is evaluated to be low and / or high. That is, a face discriminator 11 that detects the face of a person from a photographed image through evaluation of the brightness of the detection area 8 of the photographed image taken by the camera, and has different rectangular features 9a to 9g with respect to the detection region 8. And a face discriminator 11 constituted by connecting a plurality of strong discriminators 10a to 10N composed of a plurality of weak discriminators that evaluate the luminance of the detection region 8 using the Haar-like feature quantity. (See FIG. 3). The face discriminator 11 detects the face of a person by determining whether or not there is a face in the detection area 8 based on sequential determination by the plurality of strong discriminators 10a to 10N connected. Using such a face discriminator 11, the position of the face of the person whose luminance is evaluated to be low in the detection area 8 as the specific area and / or the luminance is highly evaluated in the detection area 8 as the specific area. The position of the person's face is obtained and stored in the storage unit of the computer (S002).
　次に、コンピュータを用いて、記憶部から、検出領域８において輝度が低く評価される人物の顔の位置を読み出し、透明基板上の当該位置に対応する部分に高輝度化部材の原料を搭載し、及び、検出領域８において輝度が高く評価される人物の顔の位置を読み出し、透明基板上の当該位置に対応する部分に低輝度化部材の原料を搭載する（Ｓ００３）。本実施例での透明基板は眼鏡レンズ状である。
　次に、透明基板に高輝度化部材の原料及び低輝度化部材の原料を固着させる（Ｓ００４）。 Next, using a computer, the position of the face of the person whose luminance is evaluated to be low in the detection area 8 is read from the storage unit, and the raw material for the high brightness member is mounted on the portion corresponding to the position on the transparent substrate. Then, the position of the face of the person whose luminance is highly evaluated in the detection region 8 is read, and the raw material for the low luminance member is mounted on the portion corresponding to the position on the transparent substrate (S003). In this embodiment, the transparent substrate has a spectacle lens shape.
Next, the raw material for the brightness enhancement member and the raw material for the brightness reduction member are fixed to the transparent substrate (S004).
　例えば原料として塗料を用いる場合には、固着は乾燥により行われる。また、赤外線及び紫外線については透明な反射塗料及び吸収塗料が市販されているので、原料として、これらの塗料を使用し、輝度が低く又は高く評価される所定箇所に塗布すれば良い。また、特定波長の光を反射するには、例えば、多層膜の積層構造とすることが知られているので、原料としてこれらの多層フィルムを使用し、所定箇所に多層フィルムを貼り付けても良い。また、高輝度化部材としてのフィルム及び低輝度化部材としてのフィルムを用い、透明基板上の所定箇所に貼り付けても良い。この場合、フィルムは貼り付け前は原料であり、貼り付け後は部材となる。 For example, when a paint is used as a raw material, fixing is performed by drying. Moreover, since transparent reflective paints and absorbing paints are commercially available for infrared rays and ultraviolet rays, these paints may be used as raw materials and applied to predetermined places where the luminance is low or highly evaluated. Moreover, in order to reflect light of a specific wavelength, for example, it is known to have a multilayer structure of multilayer films. Therefore, these multilayer films may be used as raw materials, and the multilayer films may be attached to predetermined positions. . Moreover, you may affix on the predetermined location on a transparent substrate, using the film as a brightness enhancement member, and the film as a brightness reduction member. In this case, the film is a raw material before being attached and becomes a member after being attached.
　また、プラスチックレンズの染色では、染色液に浸漬する方法が一般的である。レンズ全部を浸漬すると、一様な色彩のレンズが得られる。部分的に浸漬すると部分的に染色されたレンズが得られる。染色液から徐々に引き上げると色彩の濃度が徐々に変化するレンズが得られる。気相転写法（昇華性染料インクを転写紙に印刷し、染料を昇華させてレンズ面に蒸着する）でレンズ面に染料を蒸着した後にレーザー照射した場合にも一様な染色レンズが得られる。ガラスの染色は、塩化コバルト、二酸化セレン、二酸化クロム等の着色剤をガラス原料に混ぜて焼成する方法が一般的である。
　そこで、これらの技術を用いれば、一様な色彩の眼鏡レンズやゴーグル板を得られる。２種（反射と吸収、２種の反射率、２種の吸収率等）にするには、プラスチックを染色面以外をマスク（例えばメタルマスクを使用する）して、マスクパターンを変えて２回浸漬を行なえば良い。徐々に色彩濃度を変えるには、マスク時間を変えて浸漬を行なえば良い。また、ガラス板やプラスチック板に染色塗料を塗布して又は染色されたプラスチックシートを貼り付けて２種にしても良い。 In dyeing plastic lenses, a method of immersing in a dyeing solution is common. When all the lenses are immersed, a lens with uniform color is obtained. Partial immersion gives a partially dyed lens. When it is gradually lifted from the staining solution, a lens in which the color density gradually changes can be obtained. Uniform dyed lenses can be obtained even when laser irradiation is performed after vapor deposition of dye on the lens surface by vapor phase transfer method (printing sublimation dye ink on transfer paper, sublimating the dye and vapor deposition on the lens surface) . Generally, glass is dyed by mixing a colorant such as cobalt chloride, selenium dioxide, chromium dioxide or the like with a glass raw material and baking it.
Therefore, using these techniques, it is possible to obtain spectacle lenses and goggles with uniform colors. To make two types (reflection and absorption, two types of reflectance, two types of absorption rate, etc.), mask the plastic other than the stained surface (for example, use a metal mask) and change the mask pattern twice. What is necessary is just to immerse. In order to gradually change the color density, immersion may be performed while changing the mask time. Moreover, it is also possible to apply a dyeing paint to a glass plate or a plastic plate or attach a dyed plastic sheet to make two types.
　これにより、コンピュータを使用することにより、検出領域８において輝度が低く評価される人物の顔の位置に高輝度化部材を配置し、輝度が高く評価される人物の顔の位置に低輝度化部材を自動的に配置するので、高輝度化部材及び低輝度化部材の配置が適切な顔検出防止具を製造することができる。 Accordingly, by using the computer, the high brightness member is arranged at the position of the face of the person whose brightness is evaluated to be low in the detection region 8, and the low brightness member is placed at the position of the face of the person whose brightness is highly evaluated. Are automatically arranged, and thus a face detection preventing device in which the high luminance member and the low luminance member are appropriately arranged can be manufactured.
　実施例１６に、ゴーグル型の顔検出防止具であって、特徴分布に応じてコンピュータで赤外線反射フィルターと赤外線吸収フィルターとを自動配置する例を示す。ここでは、実施例１２と異なる点を主として説明する。 Example 16 is an example of a goggle-type face detection prevention device in which an infrared reflection filter and an infrared absorption filter are automatically arranged by a computer in accordance with a feature distribution. Here, differences from the twelfth embodiment will be mainly described.
　図２６に実施例１６における顔検出防止具１Ｂ９の斜視図を示す。実施例１２（図２１参照）ではゴーグル板３Ｂの眼を覆う部分が赤外線反射フィルター４Ｂ１を構成し、その下側の部分が赤外線吸収フィルター４Ｂ２を構成しているが、本実施例では部材としてのゴーグル板３Ｂに赤外線反射フィルター４Ｂ１を構成する部分と赤外線吸収フィルター４Ｂ２を構成する部分をコンピュータで自動的に配置する。 FIG. 26 is a perspective view of the face detection preventing tool 1B9 according to the sixteenth embodiment. In Example 12 (see FIG. 21), the part of the goggle plate 3B that covers the eye constitutes the infrared reflection filter 4B1, and the lower part constitutes the infrared absorption filter 4B2. A part constituting the infrared reflection filter 4B1 and a part constituting the infrared absorption filter 4B2 are automatically arranged on the goggle plate 3B by a computer.
　人物の顔を検出する顔判別器１１を用いて、顔検出防止具を未着用の撮影画像について、検出領域８において輝度が低く評価される人物の顔の位置、及び、検出領域８において輝度が高く評価される人物の顔の位置を求め、コンピュータの記憶部に記憶する。そして、コンピュータを用いて、記憶部から、検出領域において輝度が低く評価される人物の顔の位置を読み出して、ゴーグル板３Ｂ上に、高輝度化部材としての赤外線反射フィルター４Ｂ１を配置し、輝度が高く評価される人物の顔の位置を読み出して低輝度化部材としての赤外線吸収フィルター４Ｂ２を配置する。赤外線反射フィルター４Ｂ１及び赤外線吸収フィルター４Ｂ２が配置されない部分は透明部分３Ｇとなる。顔検出防止具１Ｂ９の製造方法は実施例１５の透明基板が眼鏡レンズ状であったものがゴーグル板状に変わる他は、実施例１５と同様である。
　輝度が低く評価される人物の顔の位置に赤外線反射フィルター４Ｂ１を、輝度が高く評価される人物の顔の位置に赤外線吸収フィルター４Ｂ２を配置し、両者共に顔判別器１１の判別を困難にする方向に作用するので、その結果、撮影画像がインターネット上に流出した場合でも、顔判別器は人物の顔を検出できなくなるという効果を奏する。 Using a face discriminator 11 that detects the face of a person, the position of the person's face whose luminance is evaluated to be low in the detection area 8 and the luminance in the detection area 8 of the photographed image without wearing the face detection prevention tool. The position of the face of the person who is highly evaluated is obtained and stored in the storage unit of the computer. Then, using a computer, the position of the face of the person whose luminance is evaluated to be low in the detection area is read out from the storage unit, and the infrared reflection filter 4B1 as a high luminance member is arranged on the goggle plate 3B. The position of the face of a person who is highly evaluated is read out, and an infrared absorption filter 4B2 is disposed as a low brightness member. A portion where the infrared reflection filter 4B1 and the infrared absorption filter 4B2 are not arranged becomes a transparent portion 3G. The manufacturing method of the face detection preventing tool 1B9 is the same as that of Example 15 except that the transparent substrate of Example 15 is in the shape of a spectacle lens and changes to a goggle plate shape.
An infrared reflection filter 4B1 is arranged at the position of the face of the person who is evaluated to have low brightness, and an infrared absorption filter 4B2 is arranged at the position of the face of the person who is evaluated to have high brightness, both of which make it difficult for the face discriminator 11 to discriminate. As a result, the face discriminator cannot detect the face of the person even when the photographed image flows out on the Internet.

　この場合でも、顔検出防止具１Ａ１６を装着すると、眼の部分はルーバーガラス板４Ａ１６で覆われるので、斜め方向から撮影された撮影画像において眼の部分は顔判別器１１により輝度が低く評価される。詳しくは、斜めから撮影した撮影画像に黒い平行線が入ることにより顔判別器１１が顔を認識できなくなる。その結果、斜め方向から撮影された撮影画像がインターネット上に流出した場合でも、顔判別器１１は人物の顔を検出できなくなるという効果を奏する。 FIG. 37 is a perspective view of the face detection preventing tool 1A16 according to the twenty-seventh embodiment. In the first embodiment, the entire spectacle lens portion 3A constitutes the infrared reflection filter 4A. In the present embodiment, the entire spectacle lens portion 3A is composed of the louver glass plate 4A16. On the louver glass plate 4A16, linear solar absorbers (having a width h in the thickness direction) are repeatedly arranged in the horizontal direction at intervals d. For example, the interval d is set to 0.1 to several mm. Thereby, what is beyond the louver glass plate 4A16 can be seen through from the front, but it cannot be seen from the oblique direction. As the inclination increases, the portion that cannot be seen increases and becomes invisible at a predetermined angle θ, for example, 60 degrees or more. It is represented by tan θ = dn / h (n: the refractive index of the glass plate). For example, a carbon ribbon can be used as the solar absorber.
Here, the face detection preventing tool 1B16 is a spectacle type, and the spectacle lens unit 3A as a member has a louver glass plate 4A16. A plastic plate may be used instead of the glass plate. The direction of the linear absorber may be any direction as long as it is parallel to the surface of the louver glass plate 4A16 as a member.
Even in this case, when the face detection preventing tool 1A16 is attached, the eye part is covered with the louver glass plate 4A16, so that the brightness of the eye part is evaluated by the face discriminator 11 in a captured image taken from an oblique direction. . Specifically, the face discriminator 11 cannot recognize the face when black parallel lines are included in a photographed image photographed obliquely. As a result, the face discriminator 11 has an effect that the face of the person cannot be detected even when a photographed image photographed from an oblique direction flows out on the Internet.
　実施例２８に、ゴーグル型の顔検出防止具であって、ゴーグル全体に太陽光吸収ルーバーガラスが用いられている例を示す。実施例２と異なる点を主として説明する。 Example 28 is an example of a goggle-type face detection prevention device in which sunlight absorbing louver glass is used for the entire goggle. Differences from the second embodiment will be mainly described.
　図３８に実施例２８における顔検出防止具１Ｂ１６の斜視図を示す。実施例２ではゴーグル板３Ｂ全体が赤外線反射フィルター４Ｂを構成するが、本実施例ではゴーグル板３Ｂ全体がルーバーガラス板４Ｂ１６から成る。ルーバーガラス板４Ｂ１６を使用すると、真正面からはルーバールーバーガラス板４Ｂ１６の向こうにあるものが透けてみえるが斜め方向からは見えなくなる。傾斜が大きくなるにつれて見えない部分が増え、所定の角度、例えば６０度以上では全く見えなくなる。
　ここに、顔検出防止具１Ｂ１６はゴーグル型で、部材としてのゴーグル板３Ｂはルーバーガラス板４Ｂ１６を有する。なお、ガラス板に代えてプラスチック板を用いても良い。また、線状吸収体の方向は部材としてのルーバーガラス板４Ｂ１６の表面に平行な方向であれば任意の方向で良い。
　この場合でも、顔検出防止具１Ｂ１６を装着すると、眼の部分はルーバーガラス板４Ｂ１６で覆われるので、斜め方向から撮影された撮影画像において眼の部分は顔判別器１１により輝度が低く評価される。詳しくは、斜めから撮影した撮影画像に黒い平行線が入ることにより顔判別器１１が顔を認識できなくなる。その結果、斜め方向から撮影された撮影画像がインターネット上に流出した場合でも、顔判別器１１は人物の顔を検出できなくなるという効果を奏する。 FIG. 38 is a perspective view of the face detection preventing tool 1B16 according to the twenty-eighth embodiment. In the second embodiment, the entire goggle plate 3B constitutes the infrared reflection filter 4B. In the present embodiment, the entire goggles plate 3B is composed of the louver glass plate 4B16. When the louver glass plate 4B16 is used, what is beyond the louver louver glass plate 4B16 can be seen from the front, but it cannot be seen from an oblique direction. As the inclination increases, the portion that cannot be seen increases and becomes invisible at a predetermined angle, for example, 60 degrees or more.
Here, the face detection preventing tool 1B16 is a goggle type, and the goggle plate 3B as a member has a louver glass plate 4B16. A plastic plate may be used instead of the glass plate. The direction of the linear absorber may be any direction as long as it is parallel to the surface of the louver glass plate 4B16 as a member.
Even in this case, when the face detection preventing tool 1B16 is attached, the eye part is covered with the louver glass plate 4B16, so that the brightness of the eye part is evaluated by the face discriminator 11 in a photographed image taken from an oblique direction. . Specifically, the face discriminator 11 cannot recognize the face when black parallel lines are included in a photographed image photographed obliquely. As a result, the face discriminator 11 has an effect that the face of the person cannot be detected even when a photographed image photographed from an oblique direction flows out on the Internet.
　実施例２９に、シート状の顔検出防止具であって、眼鏡の少なくとも眼を覆う部分に太陽光を吸収するルーバーシートが貼られた例を示す。ここでは、実施例２７と異なる点を主として説明する。 Example 29 shows an example of a sheet-like face detection prevention device in which a louver sheet that absorbs sunlight is attached to at least a portion of eyeglasses covering the eyes. Here, differences from the embodiment 27 will be mainly described.
　図３９に実施例２９における顔検出防止具１Ａ１７が眼鏡レンズ６Ａに貼られた状態の斜視図を示す。実施例２７では眼鏡レンズ部６Ａ全体に太陽光を吸収するルーバーガラス板４Ａ１６が用いられるが、本実施例では眼鏡レンズ６Ａの眼を覆う部分に太陽光を吸収するルーバーシート４Ａ１７が貼られる。
　ここに、顔検出防止具１Ａ１７は部材としてのルーバーシート４Ａ１７、及び装着部としてのシート裏面の接着剤層５Ａ１０を有する。なお、ルーバーシート４Ａ１７は典型的にはプラスチック製フィルムである。
　この場合でも、眼鏡に顔検出防止具１Ａ１７を装着すると、眼は太陽光を吸収するルーバーシート４Ａ１７で覆われるので、斜め方向から撮影された撮影画像において眼の部分は顔判別器１１により輝度が低く評価される。詳しくは、斜めから撮影した撮影画像に暗い平行線が入ることにより顔判別器１１が顔を認識できなくなる。その結果、斜め方向から撮影された撮影画像がインターネット上に流出した場合でも、顔判別器は人物の顔を検出できなくなるという効果を奏する。 FIG. 39 is a perspective view showing a state where the face detection preventing tool 1A17 in Example 29 is attached to the spectacle lens 6A. In Example 27, a louver glass plate 4A16 that absorbs sunlight is used for the entire spectacle lens portion 6A. In this example, a louver sheet 4A17 that absorbs sunlight is attached to a portion of the spectacle lens 6A that covers the eyes.
Here, the face detection preventing tool 1A17 has a louver sheet 4A17 as a member and an adhesive layer 5A10 on the back surface of the sheet as a mounting portion. The louver sheet 4A17 is typically a plastic film.
Even in this case, when the face detection preventive tool 1A17 is attached to the glasses, the eyes are covered with the louver sheet 4A17 that absorbs sunlight. Rated low. Specifically, the face discriminator 11 cannot recognize the face when dark parallel lines enter a photographed image photographed from an oblique direction. As a result, there is an effect that the face discriminator cannot detect a person's face even when a photographed image photographed from an oblique direction flows out on the Internet.
　実施例３０に、ゴーグルに着脱可能な顔検出防止具であって、ゴーグルの少なくとも眼を覆う位置に太陽光吸収ルーバーシートが貼られた例を示す。ここでは、実施例２８と異なる点を主として説明する。 Example 30 is an example of a face detection preventing tool that can be attached to and detached from goggles, and a solar-absorbing louver sheet is pasted at a position that covers at least the eyes of the goggles. Here, differences from the embodiment 28 will be mainly described.
　図４０に実施例３０における顔検出防止具１Ｂ１７がゴーグル板７Ｂに貼られた状態の斜視図を示す。実施例２８ではゴーグル板３Ｂ全体に太陽光を吸収するルーバーガラス４Ｂ１６が用いられるが、本実施例ではゴーグル板７Ｂの眼を覆う位置に太陽光を吸収するルーバーシート４Ｂ１７が貼られる。
　ここに、顔検出防止具１Ｂ１７は部材としてのルーバーシート４Ｂ１７、及び装着部としてのシート裏面の接着剤層５Ｂ１０を有する。なお、ルーバーシート４Ｂ１７は通常プラスチック製フィルムである。
　この場合でも、ゴーグル７に顔検出防止具１Ｂ１７を装着すると、眼は太陽光を吸収するルーバーシート４Ｂ１７で覆われるので、斜め方向から撮影された撮影画像において眼の部分は顔判別器１１により輝度が低く評価される。詳しくは、斜めから撮影した撮影画像に暗い平行線が入ることにより顔判別器１１が顔を認識できなくなる。その結果、斜め方向から撮影された撮影画像がインターネット上に流出した場合でも、顔判別器は人物の顔を検出できなくなるという効果を奏する。 FIG. 40 is a perspective view showing a state in which the face detection preventing tool 1B17 in the embodiment 30 is stuck on the goggle plate 7B. In Example 28, louver glass 4B16 that absorbs sunlight is used for the entire goggle plate 3B, but in this example, a louver sheet 4B17 that absorbs sunlight is attached to a position covering the eyes of the goggle plate 7B.
Here, the face detection preventing tool 1B17 has a louver sheet 4B17 as a member and an adhesive layer 5B10 on the back of the sheet as a mounting portion. The louver sheet 4B17 is usually a plastic film.
Even in this case, when the face detection preventive tool 1B17 is attached to the goggles 7, the eyes are covered with the louver sheet 4B17 that absorbs sunlight. Is rated low. Specifically, the face discriminator 11 cannot recognize the face when dark parallel lines enter a photographed image photographed from an oblique direction. As a result, there is an effect that the face discriminator cannot detect a person's face even when a photographed image photographed from an oblique direction flows out on the Internet.
　実施例３１に、ゴーグル型の顔検出防止具であって、ゴーグルの眼を覆う位置以外の部分に再帰反射用ビーズが用いられている例を示す。実施例２と異なる点を主として説明する。 Example 31 shows an example of a goggle-type face detection prevention device in which retroreflective beads are used in portions other than the position covering the eyes of the goggles. Differences from the second embodiment will be mainly described.
　図４１に実施例３１における顔検出防止具１Ｂ１８の斜視図を示す。実施例２ではゴーグル板３Ｂ全体が赤外線反射フィルター４Ｂを構成するが、本実施例ではゴーグル板３Ｂの眼を覆う位置以外の部分に再帰反射用ビーズ（又は乱反射用凹凸）を取り付ける。
　顔検出防止具１Ｂ１８は部材としての再帰反射用ビーズを取り付けた領域４Ｂ１８を有する。再帰反射ビーズ径は例えば数μｍ～数ｍｍとする。再帰反射用ビーズを取り付けた領域４Ｂ１８は、例えば、ゴーグル板３Ｂの中に再帰反射用ビーズを散りばめて埋め込んでも良く、再帰反射用ビーズが散りばめられた再帰反射シートをゴーグル板３Ｂの表面に貼っても良く、塗料に混ぜて塗布し固着しても良い。 FIG. 41 is a perspective view of the face detection preventing tool 1B18 according to the 31st embodiment. In Example 2, the entire goggle plate 3B constitutes the infrared reflection filter 4B. In this example, retroreflective beads (or irregular reflection irregularities) are attached to portions other than the position covering the eye of the goggle plate 3B.
The face detection preventing tool 1B18 has a region 4B18 to which retroreflective beads as members are attached. The diameter of the retroreflective beads is, for example, several μm to several mm. The region 4B18 to which the retroreflective beads are attached may be embedded, for example, with retroreflective beads scattered in the goggle plate 3B, or a retroreflective sheet on which the retroreflective beads are scattered is pasted on the surface of the goggle plate 3B. Alternatively, it may be mixed with paint and applied and fixed.
　再帰反射用ビーズは光を入射方向に反射する。また、カメラのフラッシュを使用すると強い光がカメラの方向に返ってくる。これにより、再帰反射用ビーズがある位置では、輝度が高く評価されて、顔の輝度が正しく認識されない。再帰反射用ビーズが多数使用されると顔の輝度が正しく認識されない部分が多くなり、積算されると撮影画像において顔判別器１１により輝度が高く評価される箇所が多くなる。その結果、撮影画像がインターネット上に流出した場合でも、顔判別器は人物の顔を検出できなくなるという効果を奏する。なお、眼の部分には再帰反射用ビーズは配置されない（透明領域３Ｇで覆われる）ので、顔検出防止具１Ｂ１８を装着した人物は装着しない場合と同様の景色を見ることができる。 ∙ Retroreflective beads reflect light in the incident direction. In addition, when the camera flash is used, strong light returns to the camera. Thereby, at the position where the retroreflective beads are present, the luminance is highly evaluated, and the luminance of the face is not correctly recognized. When a large number of retroreflective beads are used, there are many portions where the brightness of the face is not correctly recognized, and when the beads are integrated, there are many places where the brightness is highly evaluated by the face discriminator 11 in the photographed image. As a result, the face discriminator has an effect that the face of the person cannot be detected even when the photographed image flows out on the Internet. Since the retroreflective beads are not disposed in the eye portion (covered with the transparent region 3G), the person wearing the face detection preventing tool 1B18 can see the same scenery as when not wearing it.
　実施例３２に、ゴーグル型の顔検出防止具であって、ゴーグルの眼を覆う位置以外の部分にミラーボール状ビーズが用いられている例を示す。実施例２と異なる点を主として説明する。 Example 32 shows an example of a goggle-type face detection prevention device in which mirror ball-shaped beads are used in portions other than the position covering the eyes of the goggles. Differences from the second embodiment will be mainly described.
　図４２に実施例３２における顔検出防止具１Ｂ１９の斜視図を示す。実施例２（図１１参照）ではゴーグル板３Ｂ全体が赤外線反射フィルター４Ｂを構成するが、本実施例ではゴーグル板３Ｂの眼を覆う部分以外の部分に微小なミラーボール状ビーズ（微小半球状ビーズ）が散りばめられている。
　顔検出防止具１Ｂ１９は部材としての微小なミラーボール用ビーズを取り付けた領域４Ｂ１９を有する。ミラーボール用ビーズの直径は例えば数μｍ～数ｍｍとする。微小なミラーボール用ビーズを取り付けた領域４Ｂ１９は、例えば、ゴーグル板３Ｂの中に微小なミラーボール用ビーズを散りばめて埋め込んでも良く、微小なミラーボール用ビーズが散りばめられたシートをゴーグル板３Ｂの表面に貼っても良く、塗料に混ぜて塗布し固着しても良い。 FIG. 42 is a perspective view of the face detection preventing tool 1B19 according to the thirty-second embodiment. In Example 2 (see FIG. 11), the entire goggle plate 3B constitutes the infrared reflection filter 4B. In this example, however, minute mirror ball beads (micro hemispherical beads) are formed on portions other than the portion covering the eyes of the goggle plate 3B. ) Are scattered.
The face detection preventing tool 1B19 has a region 4B19 to which minute mirror ball beads as members are attached. The diameter of the mirror ball beads is, for example, several μm to several mm. In the region 4B19 to which the minute mirror ball beads are attached, for example, the minute mirror ball beads may be embedded in the goggle plate 3B, or a sheet on which the minute mirror ball beads are dispersed is placed on the goggle plate 3B. It may be affixed to the surface, or may be mixed with a paint and applied and fixed.
　半球状ビーズは光を半球表面から広角に反射する。したがって、半球状ビーズがある位置では、輝度が高く評価されて、顔の輝度が正しく認識されない。半球状ビーズが多数使用されると顔の輝度が正しく認識されない部分が多くなり、積算されると撮影画像において顔判別器１１により輝度が高く評価される箇所が多くなる。その結果、撮影画像がインターネット上に流出した場合でも、顔判別器は人物の顔を検出できなくなるという効果を奏する。なお、眼の部分には半球状ビーズは配置されない（透明領域３Ｇで覆われる）ので、顔検出防止具１Ｂ１９を装着した人物は装着しない場合と同様の景色を見ることができる。 Hemispherical beads reflect light from the surface of the hemisphere at a wide angle. Therefore, at a position where hemispherical beads are present, the luminance is highly evaluated, and the luminance of the face is not correctly recognized. When a large number of hemispherical beads are used, there are many portions where the luminance of the face is not correctly recognized. When the hemispherical beads are integrated, there are many places where the luminance is highly evaluated by the face discriminator 11 in the photographed image. As a result, the face discriminator has an effect that the face of the person cannot be detected even when the photographed image flows out on the Internet. Since the hemispherical beads are not arranged in the eye part (covered with the transparent region 3G), a person wearing the face detection preventing tool 1B19 can see the same scenery as when not wearing it.
　実施例３３に、ゴーグル型の顔検出防止具であって、ゴーグルに多数の赤外線反射フィルター及び赤外線吸収フィルターが散りばめられている例を示す。ここでは実施例２と異なる点を主として説明する。 Example 33 shows an example of a goggle-type face detection preventing device in which a large number of infrared reflection filters and infrared absorption filters are scattered in the goggles. Here, differences from the second embodiment will be mainly described.
　図４３に実施例３３における顔検出防止具１Ｂ２０の斜視図を示す。実施例２ではゴーグル板３Ｂ全体が赤外線反射フィルター４Ｂを構成するが、本実施例ではゴーグル板３Ｂに多数の赤外線反射フィルター４Ａ２及び赤外線吸収フィルター４Ｂ２が散りばめられている。
　顔検出防止具１Ｂ２０は、部材としてのゴーグル板３Ｂと、装着部としてのつる５Ｂを有する。
　赤外線反射フィルター４Ａ２がある部分は、顔判別器１１により輝度が高く評価され、赤外線吸収フィルター４Ｂ２がある部分は、顔判別器１１により輝度が低く評価される。これにより、顔の輝度が正しく認識されない。赤外線反射フィルター４Ａ２及び赤外線吸収フィルター４Ｂ２が多数使用されると顔の輝度が正しく認識されない部分が多くなり、積算されると撮影画像において顔判別器１１により輝度が高く又は低く評価される箇所が多くなる。その結果、撮影画像がインターネット上に流出した場合でも、顔判別器は人物の顔を検出できなくなるという効果を奏する。赤外線反射フィルター４Ａ２及び赤外線吸収フィルター４Ｂ２が配置されない領域は透明領域３Ｇである。なお、赤外線反射フィルター４Ａ２及び赤外線吸収フィルター４Ｂ２を眼を覆う位置を除いて散りばめても、多数あれば効果を奏する。 FIG. 43 is a perspective view of the face detection preventing tool 1B20 in the embodiment 33. In the second embodiment, the entire goggle plate 3B constitutes the infrared reflection filter 4B. In this embodiment, a large number of infrared reflection filters 4A2 and infrared absorption filters 4B2 are scattered on the goggles plate 3B.
The face detection preventing tool 1B20 includes a goggle plate 3B as a member and a temple 5B as a mounting portion.
The portion having the infrared reflection filter 4A2 is evaluated to have high luminance by the face discriminator 11, and the portion having the infrared absorption filter 4B2 is evaluated to have low luminance by the face discriminator 11. As a result, the brightness of the face is not correctly recognized. When a large number of infrared reflection filters 4A2 and infrared absorption filters 4B2 are used, there are many portions where the brightness of the face is not correctly recognized, and when integrated, there are many places where the brightness is evaluated high or low by the face discriminator 11 in the photographed image. Become. As a result, the face discriminator has an effect that the face of the person cannot be detected even when the photographed image flows out on the Internet. A region where the infrared reflection filter 4A2 and the infrared absorption filter 4B2 are not disposed is a transparent region 3G. Even if the infrared reflection filter 4A2 and the infrared absorption filter 4B2 are scattered except for the position covering the eyes, the effect is obtained if there are many.
　実施例３４に、眼鏡型の顔検出防止具であって、眼鏡レンズ部の眼を横切る部分の下半分が赤外線反射フィルターとして機能する例を示す。 Example 34 shows an example of a spectacle-type face detection preventing device, in which the lower half of the spectacle lens section that crosses the eye functions as an infrared reflection filter.
　図４４に実施例３４における顔検出防止具１Ａ２１の斜視図を示す。実施例１では眼鏡レンズ部３Ａ全体が赤外線反射フィルター４Ａを構成するが、本実施例では眼鏡レンズ部３Ａの眼を横切る部分の下半分に赤外線反射フィルター４Ａが存在する。顔検出防止具１Ａ２１は、部材としての眼鏡レンズ部３Ａと、装着部としてのつる５Ａを有する。
　この場合には、顔検出防止具１Ａ２１を装着すると、赤外線反射フィルター４Ａの境界が眼を横切る。上側の赤外線反射フィルター４Ａがない部分３Ｇは透明で、顔判別器１１により装着前と同様の輝度に評価されるが、下側の赤外線反射フィルター４Ａがある部分は、顔判別器１１により輝度が高く評価される。境界が眼の下端に該当する場合でも、眼の直下の輝度の低い部分の輝度が高く評価される。その結果、輝度の評価が変化することにより、撮影画像がインターネット上に流出した場合でも、顔判別器は人物の顔を検出できなくなるという効果を奏する。
　なお、変形例として眉を覆う位置にフレーム２Ａ（特にメタル製）を設けると、眉を覆う部分もフレーム２Ａによる光反射により顔判別器１１により輝度が高く評価され、顔判別器１１による人物の顔の検出をより困難にする。 FIG. 44 is a perspective view of the face detection preventing tool 1A21 according to the 34th embodiment. In the first embodiment, the entire spectacle lens portion 3A constitutes the infrared reflection filter 4A, but in this embodiment, the infrared reflection filter 4A exists in the lower half of the portion of the spectacle lens portion 3A that crosses the eye. The face detection preventing tool 1A21 has a spectacle lens part 3A as a member and a temple 5A as a mounting part.
In this case, when the face detection preventing tool 1A21 is worn, the boundary of the infrared reflection filter 4A crosses the eye. The portion 3G without the upper infrared reflection filter 4A is transparent and is evaluated by the face discriminator 11 to have the same luminance as before the attachment, but the portion with the lower infrared reflection filter 4A has the luminance by the face discriminator 11. Highly appreciated. Even when the boundary corresponds to the lower end of the eye, the luminance of the low luminance portion immediately below the eye is highly evaluated. As a result, the brightness evaluation changes, so that the face discriminator cannot detect the face of a person even when a photographed image flows on the Internet.
If a frame 2A (particularly made of metal) is provided at a position covering the eyebrows as a modified example, the brightness of the portion covering the eyebrows is also highly evaluated by the face discriminator 11 due to light reflection by the frame 2A. Make face detection more difficult.
　実施例３５に、ゴーグル型の顔検出防止具であって、ゴーグル板の眼を横切る部分の下半分が赤外線反射フィルターとして機能する例を示す。 Example 35 shows an example of a goggle-type face detection prevention device in which the lower half of the goggle plate that crosses the eye functions as an infrared reflection filter.
　図４５に実施例３５における顔検出防止具１Ｂ２１の斜視図を示す。実施例２ではゴーグル板３Ｂ全体が赤外線反射フィルター４Ｂを構成するが、本実施例ではゴーグル板３Ｂの眼を横切る部分の下半分に赤外線反射フィルター４Ｂが存在する。顔検出防止具１Ｂ２１は、部材としてのゴーグル板３Ｂと、装着部としてのつる５Ｂを有する。
　この場合には、顔検出防止具１Ｂ２１を装着すると、赤外線反射フィルター４Ｂの境界が眼を横切る。上側の赤外線反射フィルター４Ｂがない部分３Ｇは透明で、顔判別器１１により装着前と同様の輝度に評価され、下側の赤外線反射フィルター４Ｂがある部分は、顔判別器１１により輝度が高く評価される。その結果、撮影画像がインターネット上に流出した場合でも、顔判別器は人物の顔を検出できなくなるという効果を奏する。
なお、変形例として上側の赤外線反射フィルター４Ｂがない部分３Ｇの上側で眉を覆う位置にさらに赤外線反射フィルターを設けると、眉を覆う部分も顔判別器１１により輝度が高く評価され、顔判別器１１による人物の顔の検出をより困難にする。 FIG. 45 is a perspective view of the face detection preventing tool 1B21 according to the 35th embodiment. In the second embodiment, the entire goggle plate 3B constitutes the infrared reflection filter 4B, but in this embodiment, the infrared reflection filter 4B is present in the lower half of the portion of the goggle plate 3B that crosses the eye. The face detection preventing tool 1B21 includes a goggle plate 3B as a member and a temple 5B as a mounting portion.
In this case, when the face detection preventing tool 1B21 is worn, the boundary of the infrared reflection filter 4B crosses the eye. The portion 3G without the upper infrared reflection filter 4B is transparent, and is evaluated by the face discriminator 11 to have the same luminance as before mounting, and the portion having the lower infrared reflection filter 4B is evaluated by the face discriminator 11 to have high luminance. Is done. As a result, the face discriminator has an effect that the face of the person cannot be detected even when the photographed image flows out on the Internet.
As a modified example, when an infrared reflection filter is further provided at a position covering the eyebrows above the portion 3G where the upper infrared reflection filter 4B is not provided, the brightness of the portion covering the eyebrows is also highly evaluated by the face discriminator 11, and the face discriminator. 11 makes the detection of a human face more difficult.
　実施例３６に、眼鏡型の顔検出防止具であって、眼鏡レンズ部全体が紫外線反射フィルターとして機能する例を示す。ここでは実施例１と異なる点を主として説明する。 Example 36 shows an example of a spectacle-type face detection prevention device in which the entire spectacle lens unit functions as an ultraviolet reflection filter. Here, differences from the first embodiment will be mainly described.
　図４６に実施例３６における顔検出防止具１Ａ２２の斜視図を示す。実施例１では眼鏡レンズ部３Ａ全体が赤外線反射フィルター４Ａを構成するが、本実施例では眼鏡レンズ部３Ａ全体が紫外線反射フィルター４Ａ２２を構成する。紫外線も人物には感知されないがカメラには感光されるので、赤外線の場合と同様に、紫外線反射フィルター４Ａ２２が配置された部分は顔判別器１１により輝度が高く評価される。
　この場合、顔検出防止具１Ａ２２を装着すると、眼の周辺が紫外線反射フィルター４Ａ２２で覆われるので、撮影画像において眼を覆う部分は顔判別器１１により輝度が高く評価される。その結果、撮影画像がインターネット上に流出した場合でも、顔判別器は人物の顔を検出できなくなるという効果を奏する。又、光源を使用しないので、自然なコミュニケーションができる。 FIG. 46 is a perspective view of the face detection preventing tool 1A22 according to the 36th embodiment. In Example 1, the entire spectacle lens unit 3A constitutes the infrared reflection filter 4A, but in this example, the entire spectacle lens unit 3A constitutes the ultraviolet reflection filter 4A22. Since the ultraviolet rays are not perceived by the person but are exposed to the camera, the face discriminator 11 highly evaluates the luminance of the portion where the ultraviolet reflection filter 4A22 is arranged as in the case of the infrared rays.
In this case, when the face detection preventive tool 1A22 is attached, the periphery of the eye is covered with the ultraviolet reflection filter 4A22, so that the brightness of the portion covering the eye in the photographed image is highly evaluated by the face discriminator 11. As a result, the face discriminator has an effect that the face of the person cannot be detected even when the photographed image flows out on the Internet. Moreover, since no light source is used, natural communication is possible.
　眼鏡レンズ部３Ａに、紫外線反射フィルター４Ａ２２の代わりに、青色光反射フィルター及び／又は紫色光反射フィルターを用いた場合でも、カメラは青色光及び／又は紫色光に感光して、顔判別器１１は人物の顔を検出できなくなるという効果を奏する。紫外線反射フィルターと青色光及び／又は紫色光反射フィルターを用いた場合には、紫外線反射フィルターと青色光及び／又は紫色光反射フィルターの効果が加算されるので、より人の顔を検出し難くなる。このことは、以下の実施例の紫外線反射フィルターについても同様にいえる。重複を避けるため、以下の実施例の紫外線反射フィルターについては説明を省略する。 Even when a blue light reflection filter and / or a purple light reflection filter is used for the spectacle lens unit 3A instead of the ultraviolet reflection filter 4A22, the camera is sensitive to blue light and / or purple light, and the face discriminator 11 The effect is that the human face cannot be detected. When an ultraviolet reflection filter and a blue light and / or purple light reflection filter are used, the effects of the ultraviolet reflection filter and the blue light and / or purple light reflection filter are added, making it more difficult to detect a human face. . The same applies to the ultraviolet reflection filters of the following examples. In order to avoid duplication, description of the ultraviolet reflection filters of the following examples is omitted.
　実施例３７に、ゴーグル型の顔検出防止具であって、ゴーグル全体が紫外線反射フィルターとして機能する例を示す。ここでは実施例２と異なる点を主として説明する。 Example 37 shows an example of a goggle-type face detection prevention device in which the entire goggle functions as an ultraviolet reflection filter. Here, differences from the second embodiment will be mainly described.
　図４７に実施例３７における顔検出防止具１Ｂ２２の斜視図を示す。実施例２ではゴーグル板３Ｂ全体が赤外線反射フィルター４Ｂを構成するが、本実施例ではゴーグル板３Ｂ全体が紫外線反射フィルター４Ｂ２２を構成する。紫外線も人物には感知されないがカメラには感光されるので、赤外線の場合と同様に、紫外線反射フィルター４Ｂ２２が配置された部分は顔判別器１１により輝度が高く評価される。
　この場合、顔検出防止具１Ｂ２２を装着すると、眼の周辺が紫外線反射フィルター４Ｂ２２で覆われるので、撮影画像において眼を覆う部分は顔判別器１１により輝度が高く評価される。その結果、撮影画像がインターネット上に流出した場合でも、顔判別器１１は人物の顔を検出できなくなるという効果を奏する。 FIG. 47 is a perspective view of the face detection preventing tool 1B22 according to the thirty-seventh embodiment. In the second embodiment, the entire goggle plate 3B constitutes the infrared reflection filter 4B. In the present embodiment, the entire goggles plate 3B constitutes the ultraviolet reflection filter 4B22. Since the ultraviolet rays are not perceived by the person but the camera is sensitized, the face discriminator 11 evaluates the luminance of the portion where the ultraviolet reflection filter 4B22 is arranged as in the case of the infrared rays.
In this case, when the face detection preventing tool 1B22 is attached, the periphery of the eye is covered with the ultraviolet reflection filter 4B22, and thus the face discriminator 11 evaluates the luminance of the portion covering the eye to be high. As a result, the face discriminator 11 has an effect that the face of the person cannot be detected even when the photographed image flows out on the Internet.
　実施例３８に、眼鏡型の顔検出防止具であって、眼鏡レンズ部の眼を覆う部分が紫外線反射フィルターとして機能する例を示す。ここでは実施例３６と異なる点を主として説明する。 Example 38 shows an example of a spectacle-type face detection prevention device in which a portion of the spectacle lens portion covering the eye functions as an ultraviolet reflection filter. Here, differences from the embodiment 36 will be mainly described.
　図４８に実施例３８における顔検出防止具１Ａ２３の斜視図を示す。実施例３６（図４６参照）では眼鏡レンズ部３Ａ全体が紫外線反射フィルター４Ａ２２を構成するが、本実施例では眼鏡レンズ部３Ａの眼を覆う部分が紫外線反射フィルター４Ａ２２を構成する。すなわち、眼鏡レンズ部３Ａの眼から離れた部分に透明のガラス又は透明のプラスチックで構成される部分３Ｇが存在する。
　この場合でも、顔検出防止具１Ａ２３を装着すると、眼の部分は眼鏡レンズ部３Ａの紫外線反射フィルター４Ａ２２を構成する領域で覆われるので、撮影画像において眼の部分は顔判別器１１により輝度が高く評価される。その結果、撮影画像がインターネット上に流出した場合でも、顔判別器は人物の顔を検出できなくなるという効果を奏する。 FIG. 48 is a perspective view of the face detection preventing tool 1A23 in the embodiment 38. In Example 36 (see FIG. 46), the entire spectacle lens unit 3A constitutes the ultraviolet reflection filter 4A22. In this example, the portion of the spectacle lens unit 3A that covers the eyes constitutes the ultraviolet reflection filter 4A22. That is, there is a portion 3G made of transparent glass or transparent plastic in a portion away from the eye of the spectacle lens portion 3A.
Even in this case, when the face detection preventive tool 1A23 is mounted, the eye part is covered with the region constituting the ultraviolet reflection filter 4A22 of the spectacle lens unit 3A, so that the eye part has a high luminance by the face discriminator 11 in the photographed image. Be evaluated. As a result, the face discriminator has an effect that the face of the person cannot be detected even when the photographed image flows out on the Internet.
　実施例３９に、ゴーグル型の顔検出防止具であって、ゴーグルの眼を覆う部分が紫外線反射フィルターとして機能する例を示す。ここでは実施例３７と異なる点を主として説明する。 Example 39 shows an example of a goggle-type face detection preventive device in which a part of the goggles covering the eyes functions as an ultraviolet reflection filter. Here, differences from Example 37 will be mainly described.

　この場合でも、顔検出防止具１Ｂ２３を装着すると、眼の部分はゴーグル板３Ｂの紫外線反射フィルター４Ｂ２２を構成する領域で覆われるので、撮影画像において眼の部分は顔判別器１１により輝度が高く評価される。その結果、撮影画像がインターネット上に流出した場合でも、顔判別器は人物の顔を検出できなくなるという効果を奏する。 FIG. 49 is a perspective view of the face detection preventing tool 1B23 according to the 39th embodiment. In Example 37 (see FIG. 47), the entire goggle plate 3B constitutes the ultraviolet reflection filter 4B22. In this example, the portion of the goggle plate 3B that covers the eyes constitutes the ultraviolet reflection filter 4B22. That is, a part 3G made of transparent glass or transparent plastic exists in a part of the goggle plate 3B away from the eyes.
Even in this case, when the face detection preventive tool 1B23 is mounted, the eye part is covered with the region constituting the ultraviolet reflection filter 4B22 of the goggle plate 3B. Is done. As a result, the face discriminator has an effect that the face of the person cannot be detected even when the photographed image flows out on the Internet.
　実施例４０に、バイザー型の顔検出防止具であって、顔の上半分を覆う部分が赤外線反射フィルターとして機能する例を示す。ここでは実施例２と異なる点を主として説明する。 Example 40 shows an example of a visor-type face detection prevention device in which a portion covering the upper half of the face functions as an infrared reflection filter. Here, differences from the second embodiment will be mainly described.
　図５０に実施例４０における顔検出防止具１Ｃ２４の斜視図を示す。実施例２ではゴーグル板３Ｂ全体が赤外線反射フィルター４Ｂを構成するが、本実施例では顔の斜め前に突き出し、正面から見て顔の上半分を覆う、部材としてのバイザー板３Ｃが赤外線反射フィルター４Ｃ１を構成する。また、頭を取り巻く帯状部分５Ｃが装着部を構成する。
　ここにおいて、ゴーグル型及びバイザー型は、両者共に人物の顔に対向するように配置される部材が、連続する１枚の透明板（全部又は一部が半透明のものを含む）、例えばガラス板又はプラスチック板で構成される（バイザー型はプラスチック板で構成される）ものをいうものとする。また、装着時にゴーグル型は、人物の顔に接触して装着されるものをいい、バイザー型は頭部に接触するが、顔から離れて装着されるものをいうものとする。また、ゴーグル型は透明板と顔の間の空間が密閉されないものも含むものとする。
　この場合でも、顔検出防止具１Ｃ２４を装着すると、顔の上半分は赤外線反射フィルター４Ｃ１を構成する領域で覆われるので、撮影画像において眼の部分は顔判別器により輝度が高く評価される。その結果、撮影画像がインターネット上に流出した場合でも、顔判別器は人物の顔を検出できなくなるという効果を奏する。 FIG. 50 is a perspective view of the face detection preventing tool 1C24 according to the fortieth embodiment. In the second embodiment, the entire goggle plate 3B constitutes the infrared reflection filter 4B. In this embodiment, the visor plate 3C as a member protrudes diagonally forward of the face and covers the upper half of the face when viewed from the front. 4C1 is configured. Further, the belt-like portion 5C surrounding the head constitutes the mounting portion.
Here, in the goggle type and the visor type, a transparent plate (including all or a part of which is partially translucent), for example, a glass plate, is a member arranged so as to face both faces of a person. Or it shall consist of a plastic board (a visor type | mold is comprised with a plastic board). In addition, the goggle type when worn is in contact with a person's face, and the visor type is in contact with the head but worn away from the face. Further, the goggle type includes those in which the space between the transparent plate and the face is not sealed.
Even in this case, when the face detection preventing tool 1C24 is attached, the upper half of the face is covered with the region constituting the infrared reflection filter 4C1, and thus the eye part in the photographed image is highly evaluated by the face discriminator. As a result, the face discriminator has an effect that the face of the person cannot be detected even when the photographed image flows out on the Internet.
　実施例４１に、バイザー型の顔検出防止具であって、眼を覆う部分が赤外線反射フィルターとして機能する例を示す。ここでは実施例４０と異なる点を主として説明する。 Example 41 shows an example of a visor-type face detection prevention device in which the portion covering the eyes functions as an infrared reflection filter. Here, differences from the embodiment 40 will be mainly described.
　図５１に実施例４１における顔検出防止具１Ｃ２５の斜視図を示す。実施例４０ではゴーグル板３Ｃ全体が赤外線反射フィルター４Ｃ１を構成するが、本実施例では部材としてのバイザー板３Ｃは顔の斜め前に突き出し、正面から見て顔の上半分を覆うが、バイザー板３Ｃのうち、眼を覆う部分が赤外線反射フィルター４Ｃ２を構成する。また、頭を取り巻く帯状部分５Ｃが装着部を構成する。
　この場合でも、顔検出防止具１Ｃ２５を装着すると、眼は赤外線反射フィルター４Ｃ２を構成する領域で覆われるので、撮影画像において眼の部分は顔判別器１１により輝度が高く評価される。その結果、撮影画像がインターネット上に流出した場合でも、顔判別器は人物の顔を検出できなくなるという効果を奏する。 FIG. 51 is a perspective view of the face detection preventing tool 1C25 in the embodiment 41. In the embodiment 40, the entire goggle plate 3C constitutes the infrared reflection filter 4C1, but in this embodiment, the visor plate 3C as a member protrudes diagonally forward of the face and covers the upper half of the face when viewed from the front. The part which covers eyes among 3C comprises the infrared reflective filter 4C2. Further, the belt-like portion 5C surrounding the head constitutes the mounting portion.
Even in this case, when the face detection preventive tool 1C25 is attached, the eye is covered with the region constituting the infrared reflection filter 4C2, and therefore, the luminance of the eye portion in the photographed image is highly evaluated by the face discriminator 11. As a result, the face discriminator has an effect that the face of the person cannot be detected even when the photographed image flows out on the Internet.
