【産業上の利用分野】[Industrial applications]

本考案は、TVカメラ等及び例えば屋外で使用されるTVカメラ等を保護のた め収納するカメラ用ハウジングに関し、詳しくはカメラレンズの前方に平面状の 表面を持つ平板状光学要素を有するカメラ及びカメラ用ハウジングに関する。 The present invention relates to a camera housing for housing a TV camera or the like and, for example, a TV camera used outdoors, for protection, and more specifically, a camera having a flat optical element having a flat surface in front of a camera lens, The present invention relates to a camera housing.

【0002】[0002]

【従来の技術】[Prior Art]

カメラは一般にレンズ(系)を有しておりこの後方に生じる結像をフイルムに 記録したり、光電素子により画像に対応する電気信号に変換している。 レンズ系の前方には、レンズ系に入射する光を所望の特性にするため、或いは レンズの保護のために光学フイルタや平板ガラス(保護ガラス)等の平面状の表 面を持つ光学素子(以下、平板状光学要素と記述する)を配置して用いることも 多い。 A camera generally has a lens (system), and an image formed behind the lens is recorded on a film or converted into an electric signal corresponding to an image by a photoelectric element. In front of the lens system, an optical element having a flat surface such as an optical filter or flat glass (protective glass) (hereinafter referred to as an optical element) for making the light incident on the lens system have desired characteristics or for protecting the lens. , And described as a flat optical element).

【0003】 また、カメラを或いはカメラと上記平板状光学要素を合わせて、外界からの保 護のためカメラ用のハウジング或いはケースに収納して用いる場合も多い。例え ば、TVカメラを屋外に設置して長期にわたり監視用に用いるためや、水中撮影 に使うためには相応のカメラ用ハウジング(以下、ケースも含めて総称する)に 収納して使用している。この様なカメラ用ハウジングはほぼ密閉構造を取る場合 が多く、従ってやはり外部から光を入射させるために外囲器の一部に平面状の表 面を持つ平板状光学要素を設けるなければならない。この場合は単に素通しのガ ラス板で足りるが、他の機能を兼ねて前述した光学フイルタや水滴の付着を防ぐ ためのデフロスタが用いられる場合もある。In addition, the camera or the camera and the above-mentioned flat plate-shaped optical element are often combined and used in a housing or a case for the camera for protection from the outside. For example, when a TV camera is installed outdoors and used for long-term monitoring, or for underwater photography, it is housed in a corresponding camera housing (generally referred to as the case below). .. In many cases, such a camera housing has a substantially hermetically sealed structure. Therefore, in order to allow light to enter from the outside, a flat plate-shaped optical element having a flat surface must be provided in a part of the envelope. In this case, a plain glass plate is sufficient, but there are also cases where the above-mentioned optical filter and the defroster for preventing the adhesion of water droplets are used together with other functions.

【0004】 例えば、交通用画像処理装置の撮像部には上述したようなTVカメラ及びカメ ラ用ハウジングが使用されている。この装置は図2及び図3に示すように、道路 上方約6mに設置された撮像部即ち、カメラハウジング7と中に収納されたTV カメラ4を使用して道路を撮影し、その画像から交通用画像処理装置8において 走行車両9を検知したりこの車両のナンバープレートの登録番号を認識したりし ている。なお、10は夜間にも対応するための照明装置である。 車両検知や認識車両番号等の情報は、中央の処理装置へと伝送され例えば旅行 時間算定に利用され、また、通行者の便宜のため中央より推定旅行時間等の情報 が観測点の表示器11に伝送され表示される。For example, the TV camera and the camera housing as described above are used in the image pickup unit of the traffic image processing apparatus. As shown in FIG. 2 and FIG. 3, this device uses a camera housing 7 and a TV camera 4 housed inside the image pickup section installed about 6 m above the road to photograph the road, and the image is used to display traffic. The image processing device 8 detects the traveling vehicle 9 and recognizes the registration number of the license plate of this vehicle. In addition, 10 is an illuminating device for dealing with night time. Information such as vehicle detection and recognized vehicle number is transmitted to a central processing unit and used, for example, for travel time calculation. For convenience of passers-by, information such as estimated travel time from the center is displayed at the observation point display 11 Will be transmitted and displayed.

【0005】 この用途では、外界からの機械的保護及び雨滴や霧に依らず良好な画像を得る ためTVカメラ4は、図4に示すように、カメラハウジング7に収納して設置さ れる。また、上述装置は照明光が車両運転者が眩しくなく又夜間等にも機能して 好都合であるため入射する近赤外線に対応する画像を用いるように設計されてお り、例示のTVカメラ4は可視光線をカットするための可視光カットフイルタ2 をカメラ主要部1(変換部1a及びレンズ部1b)の前方に支持部3に固定し配 置している。1cは周波数フイルタを介して映像信号を取り出しす信号線である 。以上のカメラ部分は、図示を省略した適宜にカメラハウジング7の筐体5に固 定されている。In this application, the TV camera 4 is installed by being housed in a camera housing 7 as shown in FIG. 4 in order to obtain a good image regardless of mechanical protection from the outside and raindrops or fog. Further, the above-described device is designed to use an image corresponding to the incident near-infrared light because the illumination light is convenient for the vehicle driver not to be dazzled and functioning at night and the like. A visible light cut filter 2 for cutting visible light is fixed to a supporting portion 3 in front of the camera main portion 1 (converting portion 1a and lens portion 1b). Reference numeral 1c is a signal line for taking out a video signal via the frequency filter. The above-mentioned camera portion is fixed to the housing 5 of the camera housing 7 as appropriate, which is not shown.

【0006】 また、カメラハウジング7の前面即ちTVカメラ4の入射側には、外部の被写 体からの光線が透過するように透明なデフロスタ6が配設されている。デフロス タ6は、保護ガラスの役目と同時に表面に薄く被着された抵抗膜に通電して発熱 させ表面に水滴等を付着させない。このように、カメラハウジング7は筐体5及 びデフロスタ6により略密閉構造となっており、内部のTVカメラ4等を外部か ら保護している。A transparent defroster 6 is disposed on the front surface of the camera housing 7, that is, on the incident side of the TV camera 4, so that light rays from an external object can be transmitted. The defroster 6 functions as a protective glass and at the same time, energizes the resistive film thinly applied to the surface to generate heat and prevent water droplets or the like from adhering to the surface. Thus, the camera housing 7 has a substantially hermetically sealed structure by the housing 5 and the defroster 6, and protects the internal TV camera 4 and the like from the outside.

【0007】 以上のような構成の従来のカメラ(TVカメラ)4及びこれ用のカメラ用ハウ ジング7では、夫々がカメラ主要部1の前方に位置し外部からの光が通過する平 面状の表面を持つ平板状光学要素(可視光カットフイルタ2、デフロスタ6)を 備えており、しかも、カメラ主要部1の光軸と平板状光学要素(2,6)の軸と が一致して配置されていた。換言すると、平板状光学要素2,6の配置は、この 平板状光学要素2及び6の表面平面(2a、2b及び6a、6b)と該カメラ主 要部1の光軸に垂直な仮想平面S1とが平行となる配置であった。In the conventional camera (TV camera) 4 and the camera housing 7 for the conventional camera (TV camera) having the above-described structure, each is located in front of the camera main body 1 and has a flat surface through which light from the outside passes. It is equipped with a flat optical element (visible light cut filter 2, defroster 6) having a surface, and the optical axis of the camera main part 1 and the flat optical element (2, 6) are aligned with each other. Was there. In other words, the flat optical elements 2 and 6 are arranged in such a manner that the flat optical elements 2 and 6 have a surface plane (2a, 2b and 6a, 6b) and a virtual plane S1 perpendicular to the optical axis of the camera main part 1. The arrangement was parallel to.

【考案が解決しようとする課題】[Problems to be solved by the device]

上述構成の従来のカメラ4あるいはカメラ用ハウジング7では、平板状光学要 素2及び6の表面平面(2a、2b及び6a、6b)による反射光レンズ系1b に入射し、この結果、撮像面に擬似像(フレア)を結像する光学現象、いわゆる フレア現象が発生している。フレアが発生しても通常は、直接画像に比べて格段 に輝度が低く背景に比べて目立たない場合が多く、用途によっては問題としなく て良い場合もある。然しながら、上述した交通用に用いる場合等の一定状況下で は、このフレアの存在は無視できず、大問題となる。 In the conventional camera 4 or the camera housing 7 having the above-described configuration, the light is incident on the reflected light lens system 1b formed by the surface planes (2a, 2b and 6a, 6b) of the flat optical elements 2 and 6, and as a result, the image pickup surface The so-called flare phenomenon occurs, which is an optical phenomenon that forms a pseudo image (flare). Even if flare occurs, it is usually much lower in brightness than the direct image and less noticeable than the background, and depending on the application, it may not be a problem. However, under certain circumstances such as when used for transportation as described above, the existence of this flare cannot be ignored and becomes a serious problem.

【0009】 即ち、交通用画像処理に使用した場合には、夜間にはヘッドライトを点灯した 車両の前景を撮像し得られた画像からナンバー識別等のデリケートな処理をおこ なわなければならない。この場合には、従来のカメラ或いはカメラハウジングが 使用されていると、図5に一例を模式的に示すように、得られる画像の識別すべ きナンバープレート部Pに重なって(位置が一致して)ヘッドライトLにより生 じるフレアL′が生じて、登録番号数字の識別はおろかナンバープレート部Pの 抽出さえできない自体が生じ、問題であった。That is, when used for traffic image processing, it is necessary to perform delicate processing such as number identification from an image obtained by capturing an image of a foreground of a vehicle with a headlight turned on at night. In this case, if a conventional camera or camera housing is used, as shown schematically in FIG. The flare L'generated by the headlight L causes a problem that the registration number and the number cannot be identified and even the license plate P cannot be extracted.

【0010】 なお、この交通用画像処理装置の例に限らずこのフレアの問題は、撮像範囲或 いは撮影範囲に他の部分と比べて極端に輝度の高い部分が存在する場合には同様 な不都合を生じる。例えば、直射日光下で画面に水面の波による反射光がカメラ に入射する場合等、一般のカメラ(写真機)に於いても日常的に不具合が生じ得 る。The problem of flare is not limited to the example of the traffic image processing apparatus, and the same problem occurs when there is a portion having extremely high brightness in the image capturing range or the image capturing range as compared with other portions. It causes inconvenience. For example, even when a camera receives reflected light from a water surface on the screen under direct sunlight, a general camera (photographer) may have a daily problem.

【0011】 本考案は、このような状況に鑑みてなされたもので、フレアの発生の一因であ る平板状光学要素をカメラ主要部の前に配置していながら、フレアの発生を防止 したカメラ或いはカメラハウジングを提供することを目的とするものである。The present invention has been made in view of such a situation, and prevents the occurrence of flare while arranging the flat plate-shaped optical element, which is a cause of the occurrence of flare, in front of the main part of the camera. It is an object to provide a camera or a camera housing.

【0016】 TVカメラ4Aは可視光線をカットするための可視光カットフイルタ2をカメ ラ主要部1(変換部1a及びレンズ部1b)の前方に支持部3Aに固定し配置し ている。この平板状光学要素である可視光カットフイルタ2は、実施例ではカメ ラ主要部1の光学軸に対して傾けて前記支持部3Aに固定されている。即ち、平 板状光学要素2は、平板状光学要素2の表面平面2a及び2bが共に該カメラ主 要部1の光軸に垂直な仮想平面S1に対して所定角度(例えば5度程度)を成す ように支持部3Aに保持されている。これにより可視光カットフイルタ2の各表 面平面での反射光により発生するフレアは画像内に結像することが無い。The TV camera 4A has a visible light cut filter 2 for cutting visible light, which is fixed to the support portion 3A in front of the camera main portion 1 (the conversion portion 1a and the lens portion 1b). In the embodiment, the visible light cut filter 2 which is the flat optical element is fixed to the support portion 3A while being inclined with respect to the optical axis of the camera main portion 1. That is, in the flat plate optical element 2, both the surface planes 2a and 2b of the flat plate optical element 2 form a predetermined angle (for example, about 5 degrees) with respect to the virtual plane S1 perpendicular to the optical axis of the camera main part 1. It is held by the supporting portion 3A. As a result, the flare generated by the reflected light on each surface of the visible light cut filter 2 does not form an image in the image.

The defroster 6, which is a flat optical element, constitutes the front surface of the camera housing 7A, is located on the incident side of the TV camera 4A, and transmits light rays from an external subject. In the present embodiment, the defroster 6 is fixed to the housing 5A while being tilted with respect to the optical axis of the camera 4A and thus the camera main body 1. That is, the flat optical element 6 has a predetermined angle (for example, about 5 degrees) with respect to the virtual plane S1 which is perpendicular to the optical axis of the camera main part 1 such that the surface planes 6a and 6b of the flat optical element 6 are both. It is fixed to make. As a result, the flare generated by the reflected light on each surface plane of the defroster 6 does not form an image in the image of the camera.

【0018】 以上のような構成の図示した撮像部においては、TVカメラ4A及びカメラ用 ハウジング7A夫々で使用している、カメラ主要部1の前方に位置し外部からの 光が通過する平面状の表面を持つ夫々の平板状光学要素(夫々可視光カットフイ ルタ2、デフロスタ6)が、平板状光学要素2及び6の表面平面(2a、2b及 び6a、6b)と該カメラ主要部1の光軸に垂直な仮想平面S1とが平行となら ないように所定角度で配置されているため、入射光がデフロスタ6及び可視光カ ットフイルタ2を順に通過しても有害なフレアのない所望の画像が得られる。従 って、夜間にヘッドライトを点灯した車両のナンバー識別等の確実に行える。In the illustrated image pickup unit having the above-described configuration, a planar shape is used which is used in each of the TV camera 4A and the camera housing 7A and which is located in front of the camera main unit 1 and through which light from the outside passes. Each flat optical element having a surface (visible light cut filter 2, defroster 6) has a surface plane (2a, 2b and 6a, 6b) of the flat optical elements 2 and 6 and the light of the camera main part 1. Since the incident light is arranged at a predetermined angle so as not to be parallel to the virtual plane S1 perpendicular to the axis, even if the incident light passes through the defroster 6 and the visible light cut filter 2 in order, a desired image without harmful flare is obtained. can get. Therefore, it is possible to reliably identify the number of the vehicle whose headlight is turned on at night.

【0019】 なお以上説明した本願各考案は上述実施例に限らず、一般の写真機(カメラ) におけるフイルタや、カメラを収納して撮影に供する例えば水中ケースにも適用 することができ、高輝度の被写体が含まれる撮影時に有害なフレアの発生を防ぐ ことができる。The inventions described above are not limited to the above-described embodiments, but can be applied to a filter in a general camera (camera) or an underwater case in which a camera is housed for photographing, and a high brightness is obtained. It is possible to prevent harmful flare from occurring when shooting subjects that include the subject.

【0020】 又、通常は上述したような各平板状光学要素はその2つの表面平面が平行であ ることが多いが、平行でないものについては各々の表面平面が、共に前述したカ メラの仮想平面S1と平行にならないような傾きに配置する。Further, usually, in each of the flat plate-shaped optical elements as described above, the two surface planes thereof are often parallel to each other. It is arranged so as not to be parallel to the plane S1.
