〔産業上の利用分野〕
本発明は防犯や異常発見等の目的で設置される監視カメ
ラを使用した監視装置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a monitoring device using a monitoring camera installed for the purpose of crime prevention, abnormality detection, etc.
監視カメラはスーパーマーケット、銀行などの店舗やマ
ンションなどにおける防犯監視用として、また無人工場
における機械の異常発見や安全監視用としてなど、さま
ざまな分野で使用されている。Surveillance cameras are used in a variety of fields, including for crime prevention monitoring in stores such as supermarkets and banks, and condominiums, and for detecting abnormalities in machinery and monitoring safety in unmanned factories.
しかし、上記監視カメラは、１台のカメラでカバーでき
る視野には限度がある。そのため、より広い視野をカバ
ーするためには広角レンズを取りつけるとか、複数台の
カメラを設置するなどして対応しなければならない。し
かし、広角レンズは高価であり、さらに複数台のカメラ
を設置すれば、さらにコスト高になることは明らかであ
る。However, the above-mentioned surveillance cameras have a limited field of view that can be covered by one camera. Therefore, in order to cover a wider field of view, it is necessary to take measures such as attaching a wide-angle lens or installing multiple cameras. However, wide-angle lenses are expensive, and it is clear that installing multiple cameras will further increase the cost.
また、店舗等に取り付ける防犯用の監視カメラは、防犯
効果を上げる反面で、客には常に監視されているという
プライバシー侵害の脅迫感を与えることになり、この脅
迫感が店に入り難＜＜シ、客を遠ざけてしまうという欠
点がある。In addition, although security cameras installed in stores etc. improve crime prevention, they also give customers the feeling of being constantly watched and threatening to invade their privacy, and this feeling of threat makes it difficult to enter the store. However, it has the disadvantage of alienating customers.
本発明の目的は、上述した従来の監視カメラが有する欠
点を解消し、簡単な機構を組み合わせるだけで広角な視
野を得ることができ、また店舗等に使用するときは監視
カメラの設置を気付かれないようにする監視装置を提供
することにある。The purpose of the present invention is to eliminate the drawbacks of the conventional surveillance cameras mentioned above, to obtain a wide-angle field of view by simply combining simple mechanisms, and to prevent the installation of surveillance cameras from being noticed when used in stores etc. The objective is to provide a monitoring device that prevents
上記目的を達成する本発明の監視装置は、凸面鏡または
凸面鏡機能をもつフレネルミラーに監視カメラを対向さ
せて設け、前記凸面鏡またはフレネルミラーに写る像を
前記監視カメラで監視する構成にしたことを特徴とする
ものである。The monitoring device of the present invention that achieves the above object is characterized in that a surveillance camera is provided facing a convex mirror or a Fresnel mirror having a convex mirror function, and an image reflected on the convex mirror or Fresnel mirror is monitored by the surveillance camera. That is.
以下、本発明を図に示す実施例によって説明する。 Hereinafter, the present invention will be explained with reference to embodiments shown in the drawings.
第１図は本発明の監視装置の一例を概略的に示すもので
ある。FIG. 1 schematically shows an example of a monitoring device according to the present invention.
ｌは店舗等を構成する室であり、２はこの室１を囲んで
いる壁である。この壁２には凸面鏡３が取りつけられ、
店舗内を広角に写しだすようにしている。また、壁２に
は監視カメラ４が覆板２ａの陰に隠れるようにして取り
付けられ、しかも上記凸面鏡３を臨むようになっている
。1 is a room constituting a store, etc., and 2 is a wall surrounding this room 1. A convex mirror 3 is attached to this wall 2,
The interior of the store is shown at a wide angle. Further, a surveillance camera 4 is mounted on the wall 2 so as to be hidden behind the cover plate 2a, and facing the convex mirror 3.
上記監視カメラ４は、凸面鏡３に写しだされる像を撮影
するようになっており、その撮影された像は、別室５に
設置されたモニターテレビ６に映し出されるか、或いは
ビデオデツキ７で記録されるようになっている。The surveillance camera 4 is configured to photograph the image reflected on the convex mirror 3, and the photographed image is either displayed on a monitor television 6 installed in a separate room 5 or recorded on a video deck 7. It has become so.
上記監視装置によると、監視カメラ４は従来装置のよう
に店舗内を直接撮影するようにせず、凸面鏡３に写った
像を間接的に撮影するようにしている。この凸面鏡３に
写る像は、凸面鏡の像であるので、第１図に示すように
極めて広角な角度αにわたる範囲を写している。したが
って、監視カメラ４は、高価な広角レンズ等を使用しな
くても、それ以上に広角にわたる像を映し出すことがで
きる。According to the above-mentioned surveillance device, the surveillance camera 4 does not directly photograph the inside of the store as in conventional devices, but indirectly photographs the image reflected on the convex mirror 3. Since the image reflected on this convex mirror 3 is an image of a convex mirror, it reflects an extremely wide range of angle α as shown in FIG. Therefore, the surveillance camera 4 can project an image over a wider angle without using an expensive wide-angle lens or the like.
一方、店舗内にいる人の目Ｅに見える凸面鏡３内の像は
、それが凸面鏡の像であるため小さくなって見え、監視
カメラ４の存在をほとんど気付くことができないように
なっている。このように人の目Ｅに気付かれないように
するには、上記監視カメラ４が設置されている部分を覆
板２ａで隠すとか、あるいはその設置部分の照明を暗く
するようにすれば、−層効果的にすることができる。On the other hand, the image in the convex mirror 3 that is visible to the eyes E of people in the store appears small because it is an image of a convex mirror, so that the presence of the surveillance camera 4 can hardly be noticed. In order to prevent this from being noticed by people's eyes, the part where the surveillance camera 4 is installed can be hidden with a cover plate 2a, or the lighting of the installed part can be darkened. Can be layered effectively.
また、上述した監視装置において、第２図のように、凸
面鏡３を軸８を中心に左右に回転駆動するように設置す
れば、１台の監視カメラ４によって監視できる範囲を、
さらに広くすることが可能になる。In addition, in the above-mentioned monitoring device, if the convex mirror 3 is installed so as to rotate left and right around the shaft 8 as shown in FIG. 2, the range that can be monitored by one monitoring camera 4 can be
It is possible to make it even wider.
また、本発明における凸面鏡には、球面の一部を直接使
用するものに限らず、第３図に示すように、多数の環状
の傾斜鏡面３ ａ ＋ ’−’＋ ３ ａを、軸Ｃを
中心に同心状に配置して構成された所謂フレネルミラー

３° も凸面鏡と同じ機能を有しているため、広角に像
を写しだすことができる。Furthermore, the convex mirror of the present invention is not limited to one in which a part of the spherical surface is directly used, but as shown in FIG. A so-called Fresnel mirror 3' arranged concentrically at the center may also be used. This Fresnel mirror 3° also has the same function as a convex mirror, so it can project an image over a wide angle.
本発明の監視装置は、上述した店舗内の防犯監視用に限
らず、マンションなどにおける防犯用や無人工場におけ
る機械の異常や安全監視用、広告塔の照明の異常監視用
など色々な用途に適用することができる。The monitoring device of the present invention is applicable not only to the above-mentioned crime prevention monitoring in stores, but also to various uses such as crime prevention in condominiums, abnormality and safety monitoring of machinery in unmanned factories, and abnormality monitoring of lighting of advertising towers. can do.

広角な視野を得ることができる。As described above, the monitoring device according to the present invention is configured such that a monitoring camera is provided facing a convex mirror or a Fresnel mirror having a convex mirror function, and the image reflected on the convex mirror or Fresnel mirror is monitored by the monitoring camera. An extremely wide field of view can be obtained with a simple mechanism that only requires a Fresnel mirror.
また、店舗等に防犯監視用として使用するときは、監視
カメラの設置を気付かれないようにすることができる。Furthermore, when used for crime prevention monitoring in a store or the like, the installation of the surveillance camera can be done without being noticed.
