The master CPU 207 includes a face detection unit 2071 that detects the presence or absence of a face in the video imaged by the camera 101.

このようなシステムにおいて、以下、動作の説明を行う。尚、玄関子機からの一般的な呼び出し及び居室親機の応答動作の説明は本発明の要部ではないので省略し、夜間時に夜間撮像用照明の照度を徐々に上げる動作の説明を行う。
来訪者が呼出ボタン103を押下すると、来訪者の撮像するためにカメラ101が起動し、撮像した映像信号を変調部102に送信する。映像信号を受信した変調部102は映像信号を変調映像信号に変調すると共に、子機I/F111、親機I/F209を経由して復調部202に送信する。復調部202は変調映像信号を映像信号に復調し、モニタ201にて来訪者の映像を表示することができる。
また呼出ボタン103が押下されたとき、夜間判断部108が駆動し玄関周辺の照度を測定し、照度が一定値以下であった場合には、子機CPU107から低照度信号を、子機I/F111、親機I/F209を経由して親機CPU207に送信する。その後、顔検知部2071はカメラ101から送信されてきた映像に顔があるか検知動作を開始する。このとき、顔検知部2071で顔検知を行った結果、夜間時等で来訪者の顔が検知できない場合、親機CPU207から漸増供給制御信号を、親機I/F209、子機I/F111、子機CPU107を経由して夜間照明電源制御部110に送信される。すると、夜間照明電源制御部110が夜間撮像用照明109に漸増給電をすることで、照度を徐々に上げることが出来る。
The operation of such a system will be described below. A general call from the entrance unit and a description of the response operation of the room master unit are not the main part of the present invention, and thus will be omitted, and an operation of gradually increasing the illuminance of the night imaging illumination at night will be described.
When the visitor presses the call button 103, the camera 101 is activated to image the visitor, and the captured video signal is transmitted to the modulation unit 102. The modulation unit 102 that has received the video signal modulates the video signal into a modulated video signal and transmits the modulated video signal to the demodulation unit 202 via the slave unit I / F 111 and the master unit I / F 209. The demodulator 202 can demodulate the modulated video signal into a video signal and display a visitor's video on the monitor 201.
When the call button 103 is pressed, the night judgment unit 108 is driven to measure the illuminance around the entrance. If the illuminance is below a certain value, the slave CPU 107 sends a low illuminance signal to the slave I / O. F111 is transmitted to the master CPU 207 via the master I / F 209. Thereafter, the face detection unit 2071 starts detecting whether there is a face in the video transmitted from the camera 101. At this time, as a result of performing face detection by the face detection unit 2071, if a visitor's face cannot be detected at night or the like, a gradual increase supply control signal is sent from the parent device CPU 207 to the parent device I / F 209, the child device I / F 111, It is transmitted to the night illumination power supply control unit 110 via the slave CPU 107. Then, the illuminance can be gradually increased by the night illumination power supply control unit 110 gradually increasing the power supply to the night imaging illumination 109.

夜間撮像用照明109の照度が徐々に上がってくると、顔検知部2071によって来訪者の顔の検知が可能となる。すると、親機CPU207から漸増給電停止信号が親機I/F209、子機I/F111を経由し、夜間照明電源調整部110の電源調整無効部1071に送信される。その後、電源調整無効部1071は夜間照明電源制御部110の漸増給電制御を停止させて、徐々に上がっていた夜間撮像用照明109の照度を一定に保つことができる。この動作によって、来訪者の顔が認識できる程度の照度で来訪者を照らすことができるため、来訪者の不快感を低減させることができる。 When the illuminance of the night imaging illumination 109 gradually increases, the face detection unit 2071 can detect the visitor's face. Then, the incremental power supply stop signal is transmitted from the master CPU 207 to the power adjustment invalidation unit 1071 of the night illumination power supply adjustment unit 110 via the master unit I / F 209 and the slave unit I / F 111. Thereafter, the power adjustment invalidation unit 1071 can stop the gradually increasing power supply control of the night illumination power supply control unit 110, and can keep the illuminance of the night imaging illumination 109 that has been gradually increased constant. This operation makes it possible to illuminate the visitor with an illuminance that allows the face of the visitor to be recognized, thereby reducing the discomfort of the visitor.

また、威嚇ボタン203の押下や、センサカメラ3のセンサ検出があった場合には、親機CPU207から漸増給電無効信号が親機I/F209、子機I/F111を経由し、夜間照明電源調整部110に送信される。夜間撮像用照明109は、電源調整無効部1071によって夜間照明電源制御部110の漸増給電制御が無効となり、突然、夜間撮像用照明109が点灯させることができる。この動作によって、不審者等に威嚇を行うことができる。また、夜間照明電源調整部110は居室親機2によって調整することができる。 When the threatening button 203 is pressed or the sensor of the sensor camera 3 is detected, a power supply invalid signal is gradually increased from the master unit CPU 207 via the master unit I / F 209 and the slave unit I / F 111 to adjust the night illumination power supply. Is transmitted to the unit 110. The night imaging illumination 109 can be turned on suddenly by the power adjustment invalidating unit 1071 with the gradually increasing power supply control of the night illumination power source control unit 110 being invalidated. This operation can threaten a suspicious person or the like. Further, the night illumination power supply adjustment unit 110 can be adjusted by the room master unit 2.
