【０００２】
【従来の技術】
従来、監視カメラ設置時の配線工事に係わる手間や時間、費用を削減するための方法が各種提案されている（例えば、特許文献１を参照）。図８は、従来の監視カメラの概略構成を示す模式図である。図８に示すように、カメラ部８１で撮影した画像データがアンテナ部８２から無線で伝送される構成となっており、このため画像伝送用の配線及び工事が不要となる。一方、監視カメラの動作電源は、ＡＣ電源用プラグ８３をＡＣコンセントに接続することによって得る構成となっている。
【０００３】
【特許文献１】
特開平６−３２６８９９号公報（第３−４頁、図２）
【０００４】
【発明が解決しようとする課題】
しかしながら、上記従来の監視カメラでは、画像データの伝送用配線は不要であるが、カメラ本体の設置及び電源供給用配線、ＡＣコンセントの設置工事等はやはり必要であり、結局これらの工事を行わなければならないという問題があった。このため、特に既存の建造物へ監視カメラを後付けする場合や、仮設、移設を行う場合などにおいて、工事期間中は工事場所周辺が使用できず、また設置工事に伴う騒音や粉塵が発生し、さらに工事業者が出入りするため個人のプライバシー保護や企業秘密等のセキュリティ確保のために何らかの対策が必要であるなど、設置に係わる煩雑な問題が多数あった。
【０００５】
そこで、本発明は、上記課題に鑑みてなされたものであり、電源供給用の配線工事が不要で、しかも新たに設置スペースを確保することなく容易に設置が行える監視カメラを提供することを目的とする。
【０００６】

【０００７】
上記構成によれば、監視カメラを、既存の照明装置の管球用または電球用ソケットにそのまま取り付けられるため、電源供給用の配線工事が不要で、既存の建造物への後付けや仮設、移設が容易に行える。また、監視カメラ用の特別な設置スペースを必要としないため、設置場所の美観を損なうことがない。更に、照明装置は通常、部屋の入口や中央部など複数の箇所にあるため、撮像に効果的な設置場所を任意に選択できる。
【０００８】
また、請求項２に記載の監視カメラは、請求項１に記載の監視カメラにおいて、前記口金部から給電される管球または電球からなる照明手段を更に備えることを特徴とする。
【０００９】

また、請求項５に記載の監視カメラは、請求項１乃至４のいずれかに記載の監視カメラにおいて、前記撮像手段は、撮像対象領域を自在に変更するための駆動手段を有することを特徴とする。
【００１５】
上記構成によれば、撮像領域が固定されず、移動自在であるため、撮像可能範囲が広がり、被写体の動きに追従した撮像などが可能となる。また、撮像領域の調整を自動化することにより、広範囲の領域を監視することができる。更に、レンズ系を駆動して望遠や広角の撮影を行うことにより、被写体を鮮鋭に捉えることが可能である。
【００１６】
【発明の実施の形態】
以下、本発明に係わる監視カメラの好ましい実施の形態について、図面を用いて詳細に説明する。尚、実施の形態を説明するための全図において、同一機能を有するものは同一符号を付与し、説明は繰り返さないこととする。
【００１７】
［実施の形態１］
図１は、本発明の実施の形態１における監視カメラの外観を示す斜視図である。本実施の形態における監視カメラ１００は、主に、口金部１１、カメラ部１２、などで構成される。
【００１８】
図１に示すように、監視カメラ１００の口金部１１は、例えばＧ１３口金など、既存の管球用の口金規格に適合した形状となっている。口金部１１は管球用ソケットに装着可能で、既存の蛍光灯設置スペースにそのまま設置できる形状、サイズとなっている。また、カメラ部１２は、口金部１１を介して供給される照明用の電源を利用して撮影動作を行う。撮影された画像データは、口金部１１を介して接続する電力線を通じて外部へ伝送される。
【００１９】
次に、監視カメラ１００の内部構成について説明する。図２は、本発明の実施の形態１における監視カメラ１００の、カメラ部１２の内部構成を示すブロック図である。
【００２０】
カメラ部１２は、主に、電源回路部２１、撮像部２２、画像圧縮部２３、電力線モデム２４で構成される。電源回路部２１は、照明用電源ライン（電力線２５）からの交流電源を直流に変換する。撮像部２２は、被写体の画像を撮影するための撮像素子で、画像圧縮部２３は、撮像部２２で生成した画像データを公知の方式で伝送用に圧縮する。また、電力線モデム２４は、画像圧縮部２３で圧縮した画像データを、電力線２５を通じて外部へ伝送するモデムで、これも公知のモデムを用いてかまわない。
【００２１】
尚、カメラ部１２は、撮像部２２を駆動するためのステッピングモータやギア装置（いずれも図示省略）を有し、遠隔の操作者によりカメラの光軸が前後左右に走査可能となっている。また、撮像部２２のレンズ系にも駆動装置（図示省略）を有し、同様に、遠隔の操作者により望遠、広角の撮像が可能となっている。尚、撮像領域は周期的に自動で走査するように設定してもかまわない。更に、被写体に応じて焦点を自動的に調整する自動焦点（ＡＦ）機能を搭載してもよい。
【００２２】
次に、上記構成の監視カメラ１００の動作について説明する。図３は、本発明の実施の形態１における監視カメラ１００を用いた監視システムの構成を示す模式図である。監視システムは、主に、監視カメラ１００、管球用ソケット３１、電力線２５、ＡＣコンセント３２、受信装置３３、などで構成される。
【００２３】
監視カメラ１００を管球用ソケット３１に装着すると、カメラ部１２の撮像部２２、画像圧縮部２３及び電力線モデム２４へ電力が供給され、撮像動作が開始される。撮像部２２が撮影した被監視エリア３５の被写体３６の映像信号は、画像圧縮部２３へ送られ、Ａ／Ｄ変換後、画像圧縮符号化方式の一つであるＭＰＥＧ−４方式などで圧縮される。圧縮された画像データは電力線モデム２４へ送られ、変調された信号が電力線２５へ送出される。
【００２４】
一方、送出された信号は、画像監視ルーム３７へ伝送される。監視カメラ１００の操作を行う場合、操作者はこの画像監視ルーム３７から遠隔で操作を行う。受信装置３３のＡＣプラグ３４を画像監視ルーム３７に既設のＡＣコンセント３２へ接続することにより、監視カメラ１００と受信装置３３とが電力線２５を介して接続される。図４は、受信装置３３の内部構成を示すブロック図である。受信装置３３は、主に、受信部４１、画像モニタ４２で構成される。受信部４１は、更に、電力線モデム４３、画像伸張部４４を有する。
【００２５】
受信部４１の電力線モデム４３は、受信信号を復調して画像伸張部４４へ出力する。画像伸張部４４は、画像データを公知の方法で伸張した後、Ｄ／Ａ変換等を行い、映像信号を出力する。画像モニタ４２は、出力された映像信号に基づいて画像表示を行う。
【００２６】
以上のように、本発明の実施の形態１における監視カメラ１００によれば、既存の管球用ソケット３１にカメラ本体を装着するだけで撮像並びに画像データの送信が行えるので、煩雑な電源供給用配線や画像伝送用配線が不要となる。また、設置作業が簡単なため、既存の建造物への後付けや仮設、移設が容易に行える。また、監視カメラ１００の電源のオン、オフは、監視カメラを装着したソケットに係わるスイッチを利用できる。
【００２７】
［実施の形態２］
図５は、本発明の実施の形態２における監視カメラの外観を示す斜視図である。本実施の形態における監視カメラ２００は、主に、口金部５１、カメラ部５２、などで構成される。
【００２８】
図５に示すように、本実施の形態の監視カメラ２００は、前述の実施の形態１の監視カメラ１００と比較して、口金部５１が管球用ではなく、捻じ込み式の電球用の形状となっている。口金部５１は、例えばＥ１７口金などであり、電球用ソケットに装着可能で、既存の電球設置スペースにそのまま設置できる形状、サイズとなっている。
【００２９】
尚、カメラ部５２の内部構成は、実施の形態１の監視カメラ１００のそれと同様であるので、説明を省略する。また、本実施の形態の監視カメラ２００の動作についても、実施の形態１の監視カメラ１００のそれと同様であるので、説明を省略する。
【００３０】
以上のように、本発明の実施の形態２における監視カメラ２００によれば、既存の電球用ソケットにカメラ本体を装着するだけで撮像並びに画像データの送信が行えるので、煩雑な電源供給用配線や画像伝送用配線が不要となる。また、設置作業が簡単なため、既存の建造物への後付けや仮設、移設が容易に行える。また、監視カメラ２００の電源のオン、オフは、監視カメラを装着したソケットに係わるスイッチを利用できる。
【００３１】
［実施の形態３］
図６は、本発明の実施の形態３における監視カメラの外観を示す斜視図である。本実施の形態における監視カメラ３００は、主に、管球部６１、口金部６２、カメラ部６３、などで構成される。
【００３２】
図６に示すように、本実施の形態の監視カメラ３００は、前述の実施の形態１の監視カメラ１００と比較して、管球部６１が付加された構成となっている。管球部６１とカメラ部６３とは着脱可能で、管球部６１が消耗した場合に取り替えることができる。図７は、本発明の実施の形態３における監視カメラ３００の、管球部６１を脱着した状態を示す斜視図である。管球部６１の口金部７１は、Ｇ１３口金などの既存規格に適合した形状で、対向するカメラ部６３は、それに接続可能なＧ１３口金用ソケット７２で構成することが好ましい。口金部６２から管球部６１への電源供給は、カメラ部６３の内部に設けた電源用配線７３、ソケット７２及び口金部７１を介して行われる。
【００３３】
尚、カメラ部６３の内部構成は、実施の形態１の監視カメラ１００のそれと同様であるので、説明を省略する。また、本実施の形態の監視カメラ３００の動作についても、実施の形態１の監視カメラ１００のそれと同様であるので、説明を省略する。
【００３４】
以上のように、本発明の実施の形態３における監視カメラ３００によれば、管球部６１を有するため、実施の形態１の監視カメラ１００と比較して、撮影対象領域を適切な明るさに保つことが可能で、周辺部が暗いような場合でも鮮明な画像を得ることができる。
【００３５】
尚、上記の実施の形態では画像モニタ４２を用いたが、これは画像データ蓄積装置であっても構わない。また、同様に、上記の実施の形態では電力線モデム４３を用いたが、これは無線モデムであっても構わない。
【００３６】
また、上記の実施の形態では、管球即ち蛍光灯と同形状の口金や、白熱球などの電球と同形状の口金を有する監視カメラについて説明したが、その他にも、片口金蛍光灯などと同形状の口金を有する監視カメラとし、そのソケットに装着可能にしても本発明の主旨が同様に実現されることは言うまでもない。
【００３７】
【発明の効果】
以上のように、本発明によれば、監視カメラを既存の照明装置の管球用または電球用ソケットにそのまま取り付けられるため、電源供給用の配線工事が不要で、かつ設置作業が簡単なため、既存の建造物への後付けや仮設、移設が容易に行える。また、新たな設置スペースを必要としないため、設置場所における美観が損なわれず、従ってカメラの存在が目立ちにくい。そのため、防犯用途に使用する場合などにおいて好適である。
