Description
本発明は、アクションカメラ等の小型カメラ装置に関する。 The present invention relates to a small camera device such as an action camera.
従来、カメラレンズの周囲に複数のＬＥＤが均等に配置された小型カメラ装置が知られている（例えば、特許文献１、２参照）。 Conventionally, a small camera device in which a plurality of LEDs are evenly arranged around a camera lens is known (see, for example, Patent Documents 1 and 2).
このように、カメラレンズの周囲に均等にＬＥＤを配置することで、撮影対象に対して、均一に光を照射できるため、暗い場所での撮影であっても、全体に均一な照度の画像を得ることができる。 By arranging the LEDs evenly around the camera lens in this way, it is possible to uniformly irradiate the subject to be photographed, so that an image with uniform illuminance can be obtained even when shooting in a dark place. Obtainable.
しかし、特許文献１、２に開示された小型カメラ装置を、眼鏡等の被装着部材に装着した場合には、小型カメラ装置と被装着部材とが隣接する。その状態でＬＥＤを照射すると、被装着部材で光が反射して、被装着部材に近い側の画像において照度が高まってしまうという問題があった。 However, when the small camera device disclosed in Patent Documents 1 and 2 is attached to an attached member such as eyeglasses, the small camera device and the attached member are adjacent to each other. When the LED is irradiated in that state, there is a problem that the light is reflected by the mounted member and the illuminance increases in the image on the side close to the mounted member.
本発明はかかる点に鑑みてなされたものであり、その目的は、被装着部材での照明用ＬＥＤ光の反射の影響を抑制し、高品質の画像が得られるカメラ装置を提供することにある。 The present invention has been made in view of the above points, and an object of the present invention is to provide a camera device capable of obtaining a high-quality image by suppressing the influence of reflection of LED light for illumination on a mounted member. ..
上記の目的を達成するため、この発明では、カメラレンズの周囲に複数の照明用ＬＥＤを均等に配置するカメラ装置の側面に被装着部材に対する装着部を設け、装着部とカメラレンズとの間にＬＥＤを配置しない領域を設けるようにした。 In order to achieve the above object, in the present invention, a mounting portion for the mounted member is provided on the side surface of the camera device in which a plurality of lighting LEDs are evenly arranged around the camera lens, and between the mounting portion and the camera lens. An area where the LED is not arranged is provided.
具体的には、本発明のカメラ装置は、カメラレンズの周囲に複数のＬＥＤを配置するカメラ装置であって、被装着部材に対して前記カメラ装置を装着するための装着部は、前記ＬＥＤ及び前記カメラレンズが装着される筐体の外周面の一部であり、前記装着部と前記カメラレンズとの間に、前記ＬＥＤが配置されない第１の領域が設けられ、前記ＬＥＤは、前記カメラ装置の前方に光を出射し、前記カメラ装置が前記被装着部材に装着された場合、前記装着部は、前記被装着部材の表面に接しており、前記複数のＬＥＤの配置間隔が、前記装着部と前記カメラレンズとの間の領域よりも当該領域以外の領域で狭くなっていることを特徴とする。 Specifically, the camera device of the present invention is a camera device in which a plurality of LEDs are arranged around a camera lens, and the mounting portion for mounting the camera device on a mounted member is the LED and the mounting portion. It is a part of the outer peripheral surface of the housing in which the camera lens is mounted, and a first region in which the LED is not arranged is provided between the mounting portion and the camera lens, and the LED is the camera device. When the camera device is mounted on the mounted member by emitting light in front of the mounted member, the mounted portion is in contact with the surface of the mounted member, and the arrangement interval of the plurality of LEDs is set to the mounting portion. It is characterized in that it is narrower in a region other than the region between the camera lens and the camera lens .
この構成によれば、被装着部材とカメラレンズとの間にＬＥＤが配置されないため、カメラレンズ近傍の被装着部材での光の反射を抑制でき、被装着部材に近い側の画像において照度の高まりに起因する画像の悪化を防止できる。また、撮影対象に対して、均一に光を照射できるため、暗い場所での撮影であっても、全体に均一な照度の画像を得ることができる。 According to this configuration, since the LED is not arranged between the mounted member and the camera lens, the reflection of light on the mounted member near the camera lens can be suppressed, and the illuminance increases in the image on the side close to the mounted member. It is possible to prevent deterioration of the image due to the above. Further, since the imaged object can be uniformly irradiated with light, it is possible to obtain an image having uniform illuminance as a whole even when the image is taken in a dark place.
筐体は、略円筒形状または多角柱形状であるのが好ましい。装着部は、筐体の外周面に設けられた平坦面または曲面であるのが好ましい。 The housing preferably has a substantially cylindrical shape or a polygonal prism shape. The mounting portion is preferably a flat surface or a curved surface provided on the outer peripheral surface of the housing .
この構成によれば、カメラ装置の位置が安定する。 According to this arrangement, the position of the camera device is stabilized.
第１の領域は、カメラ装置の前方から見て、カメラレンズの中心と装着部の端部とを結ぶ線と、装着部とで囲まれる領域に略等しい、のが好ましい。 It is preferable that the first region is substantially equal to the region surrounded by the line connecting the center of the camera lens and the end portion of the mounting portion and the mounting portion when viewed from the front of the camera device.
この構成によれば、カメラレンズ近傍の被装着部材での光の反射を確実に抑制できる。 According to this configuration, it is possible to reliably suppress the reflection of light on the mounted member near the camera lens.
第１の領域を除き、複数のＬＥＤがカメラレンズの周囲に均等に配置されているのが好ましい。 Except for the first region, it is preferable that the plurality of LEDs are evenly arranged around the camera lens.
この構成によれば、撮影対象に対して、均一に光を照射できるため、暗い場所での撮影であっても、全体に均一な照度の画像を得ることができる。 According to this configuration, it is possible to uniformly irradiate the imaged object with light, so that an image having uniform illuminance can be obtained even in a dark place.
以上説明したように、本発明によると、カメラレンズ近傍に配置されたＬＥＤからの光が被装着部材で反射されるのを抑制でき、高品質の画像が得られる。 As described above, according to the present invention, it is possible to suppress the light from the LED arranged near the camera lens from being reflected by the mounted member, and a high-quality image can be obtained.

（ＬＥＤと被装着部材との配置関係）
図６に示すように、眼鏡１００のフレーム１００ａの表面に、カメラ装置１０が装着されている。フレーム１００ａの側面と、カメラ装置１０の装着部である平坦面１１ａとが接しており、平坦面１１ａ近傍を除いて、照明部１３の枠体１３ａにＬＥＤ１３ｂが配置されている。
(Arrangement relationship between LED and mounted member)
As shown in FIG. 6, the camera device 10 is mounted on the surface of the frame 100a of the eyeglasses 100. The side surface of the frame 100a is in contact with the flat surface 11a which is the mounting portion of the camera device 10, and the LED 13b is arranged on the frame 13a of the lighting unit 13 except for the vicinity of the flat surface 11a.
ＬＥＤ１３ｂは、撮影対象を照明し、良好な画像を取得するために設けられており、上述したように、ケーブル３０及びフレキシブル配線１６を介して、ＬＥＤ１３ｂに電力が供給される。 The LED 13b is provided to illuminate the object to be photographed and acquire a good image, and as described above, power is supplied to the LED 13b via the cable 30 and the flexible wiring 16.
ＬＥＤ１３ｂは、枠体１３ａの内周方向に７つ配置されており、個々の間隔は略一定である。つまり、接触面近傍を除いて、ＬＥＤ１３ｂは、均等に配置されている。 Seven LEDs 13b are arranged in the inner peripheral direction of the frame body 13a, and the intervals between the LEDs 13b are substantially constant. That is, the LEDs 13b are evenly arranged except in the vicinity of the contact surface.
枠体１３ａの中央部は開口しており、その後方にカメラレンズ１４ａが配置されている。 The central portion of the frame body 13a is open, and the camera lens 14a is arranged behind the opening.
ここで、被装着部材であるフレーム１００ａの表面でＬＥＤ光が反射したときの影響について説明する。 Here, the influence when the LED light is reflected on the surface of the frame 100a which is the mounted member will be described.
図７は、被装着部材でのＬＥＤ出射光の反射の影響を説明する模式図である。 FIG. 7 is a schematic view illustrating the influence of the reflection of the LED emitted light on the mounted member.
平坦面１１ａから離れた位置にあるＬＥＤ１３ｂ（以下、ＬＥＤ１という）から出射された光は、ＬＥＤ１の放射角の範囲で、連続的な照度分布をもって照射面に到達する。 The light emitted from the LED 13b (hereinafter referred to as LED1) located at a position away from the flat surface 11a reaches the irradiation surface with a continuous illuminance distribution within the range of the radiation angle of the LED1.
しかし、平坦面１１ａ近傍の位置するＬＥＤ１３ｂ（以下、ＬＥＤ２という）から出射された光は、一部がそのまま照射面に到達するが、一部はフレーム１００ａ表面で反射され、向きを変えて照射面に到達する。 However, a part of the light emitted from the LED 13b (hereinafter referred to as LED2) located near the flat surface 11a reaches the irradiation surface as it is, but a part of the light is reflected by the surface of the frame 100a and changes its direction to change the direction of the irradiation surface. To reach.
その結果、照射面上では、反射光の影響を受けて、一部の領域で照度が不連続に高まってしまう。 As a result, the illuminance on the irradiated surface is discontinuously increased in a part of the area due to the influence of the reflected light.
筐体１１に装着される全てのＬＥＤ１３ｂからの出射光を合成した場合も、反射光の影響で、部分的に照度が高まってしまい、撮影画像にハレーション等を起こしたりする。 Even when the light emitted from all the LEDs 13b mounted on the housing 11 is combined, the illuminance is partially increased due to the influence of the reflected light, which causes halation or the like in the captured image.
そこで、本実施の形態に示すように、カメラ装置１０の装着部である平坦面１１ａ近傍を除いてＬＥＤ１３ｂを配置することで、フレーム１００ａ表面で反射光が発生するのを抑制できる。 Therefore, as shown in the present embodiment, by arranging the LED 13b except for the vicinity of the flat surface 11a, which is the mounting portion of the camera device 10, it is possible to suppress the generation of reflected light on the surface of the frame 100a.
特に、図６に示す、カメラレンズ１４ａの中心と平坦面１１ａの端部とを結ぶ仮想線である破線と、平坦面１１ａとで囲まれる三角形の領域Ａに、ＬＥＤ１３ｂが配置されないようにすると、フレーム１００ａ表面での反射光の発生を確実に抑制できる。 In particular, if the LED 13b is not arranged in the triangular region A surrounded by the broken line, which is a virtual line connecting the center of the camera lens 14a and the end of the flat surface 11a, and the flat surface 11a shown in FIG. The generation of reflected light on the surface of the frame 100a can be reliably suppressed.
なお、図示しないが、フレーム１００ａに対するカメラ装置１０の装着部が、平坦面１１ａではなく曲面であるときは、カメラ装置１０の前方から見て、カメラレンズ１４ａの中心と曲面の端部とを結ぶ仮想線と、曲面とで囲まれる領域が、上記の領域Ａに対応する。 Although not shown, when the mounting portion of the camera device 10 with respect to the frame 100a is a curved surface instead of the flat surface 11a, the center of the camera lens 14a and the end of the curved surface are connected when viewed from the front of the camera device 10. The area surrounded by the virtual line and the curved surface corresponds to the above area A.
また、ＬＥＤ１３ｂが配置されない領域は、領域Ａに略等しくてもよい。例えば、反射光の影響が実用上影響を与えない範囲で、ＬＥＤ１３ｂの一部分が領域Ａにあってもよい。 Further, the area where the LED 13b is not arranged may be substantially equal to the area A. For example, a part of the LED 13b may be in the region A as long as the influence of the reflected light does not have a practical effect.
以上、説明したように、本実施の形態によれば、カメラ装置１０の装着部とフレーム１００ａとの接触面近傍にＬＥＤ１３ｂを配置しない構成であるため、ＬＥＤ１３ｂからの光が、フレーム１００ａの表面で反射して、カメラレンズ１４ａに入射する量を大幅に低減できる。 As described above, according to the present embodiment, since the LED 13b is not arranged near the contact surface between the mounting portion of the camera device 10 and the frame 100a, the light from the LED 13b is emitted from the surface of the frame 100a. The amount of reflection that is incident on the camera lens 14a can be significantly reduced.
従って、被装着部材であるフレーム１００ａに近い側の画像において、照度の高まりに起因する画像の悪化を防止でき、高品質の画像を得ることができる。 Therefore, in the image on the side close to the frame 100a, which is the mounted member, deterioration of the image due to the increase in illuminance can be prevented, and a high quality image can be obtained.
また、カメラ装置１０の円筒状の筐体１１に平坦面１１ａが設けられているため、カメラ装置１０が転がるのを防止する治具等を別途、準備することなく、カメラ装置１０の検査、例えば、重力方向の検査も容易に行うことができる。 Further, since the flat surface 11a is provided on the cylindrical housing 11 of the camera device 10 , inspection of the camera device 10 , for example, without separately preparing a jig or the like for preventing the camera device 10 from rolling, for example. , The inspection in the direction of gravity can be easily performed.
また、フレーム１００ａの装着面に対して、カメラ装置１０の装着部である平坦面１１ａが接するようにすることで、機器や器具への装着も容易となるとともに、カメラ装置１０の位置が安定する。 Further, by making the flat surface 11a, which is the mounting portion of the camera device 10, in contact with the mounting surface of the frame 100a, it is easy to mount the camera device 10 on a device or an instrument, and the position of the camera device 10 is stabilized. ..
また、接触面近傍を除いて、ＬＥＤ１３ｂが均等に配置されていることにより、撮影対象に対して、均一に光を照射できるため、暗い場所での撮影であっても、全体に均一な照度の画像を得ることができる。 Further, since the LEDs 13b are evenly arranged except in the vicinity of the contact surface, it is possible to uniformly irradiate the imaged object with light, so that even when photographing in a dark place, the illuminance is uniform throughout. You can get an image.
