본 고안은 비디오 카메라의 무인감시회로에 관한 것으로, 더욱 상세하게는 비디오 카메라의 영상출력을 픽쳐 인 픽쳐(picture in picture)방식으로 브이티알에 녹화하여 감시요원이 부재시에도 감시기능을 수행할 수 있도록 한 비디오 카메라의 무인감시회로에 관한 것이다.The present invention relates to an unmanned surveillance circuit of a video camera. More specifically, the video output of the video camera is recorded in a VTI in a picture in picture manner so that the surveillance personnel can perform a surveillance function even when they are not present. It relates to an unmanned surveillance circuit of a video camera.
종래의 비디오 카메라를 이용한 감시장치는 감시요원이 항상 감시모니터를 주시하고 있어야 하며, 감시요원이 부재시에는 감시기능을 수행하지 못하고 또한, 비디오 카메라를 항시 켜놓으므로써 전력의 낭비와 비디오 카메라의 수명이 단축되는 문제점이 있었다.Surveillance devices using conventional video cameras should always be watched by the surveillance personnel. In the absence of the surveillance personnel, the surveillance functions cannot be performed. There was a problem that is shortened.
본 고안은 이와 같은 문제점을 해결하기 위해 안출된 것으로, 브이티알의 녹화모우드에서 초인종의 출력을 감지한 후 비디오 카메라를 작동시켜 이 비디오 카메라의 영상출력을 일정시간동안 픽쳐 인 픽쳐 방식으로 녹화시키도록 고안된 것을 특징으로 한다.The present invention was devised to solve such a problem. After detecting the doorbell's output in VTI's recording mode, the video camera is operated to record the video output of the video camera for a certain time in a picture-in-picture manner. It is characterized by the design.
이하, 본 고안의 실시예를 첨부도면에 의해 상세히 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
초인종 출력(BS)이 입력되면 제어출력단자(C1)(C2)를 통해 비디오 카메라 제어회로와 픽쳐 인 픽쳐 제어신호를 출력하는 마이콤(20)과, 이 마이콤(20)의 비디오 카메라 제어신호에 의해 전원이 "온"되어 작동하는 비디오 카메라(10)와, 상기 마이콤(20)의 픽쳐 인 픽쳐 제어신호에 의해 상기 비디오 카메라(10)의 영상출력과 고주파신호(RF)를 픽쳐 인 픽쳐 방식으로 합성하는 픽쳐 인 픽쳐 제어회로(30)와, 이 픽쳐 인 픽쳐 제어회로(30)의 출력을 처리하는 통상의 영상신호처리부(40)와 영상신호를 녹화하는 녹화부(50)로 구성된다.When the doorbell output BS is input, the microcomputer 20 outputs a video camera control circuit and a picture-in-picture control signal through the control output terminals C1 and C2, and by the video camera control signal of the microcomputer 20. The video output of the video camera 10 and the high frequency signal RF are synthesized in a picture-in-picture manner by the video camera 10 operating with the power "on" and the picture-in-picture control signal of the microcomputer 20. A picture-in-picture control circuit 30, a normal video signal processing unit 40 for processing the output of the picture-in-picture control circuit 30, and a recording unit 50 for recording video signals.
다음에는 상기와 같은 구성으로 된 본 고안 실시예의 작용을 첨부된 제 2 도의 기능흐름도에 따라 설명한다.Next, the operation of the embodiment of the present invention having the configuration as described above will be described according to the functional flow chart of FIG.
녹화모우드에서 마이콤(20)은 초인종 출력(BS)의 유무를 체크하고(101), 초인종 출력(BS)이 있으며 마이콤(20)의 제어출력단자(C1)(C2)를 통해 비디오 카메라 제어신호와 픽쳐 인 픽쳐 제어신호를 출력하여 비디오 카메라(10)와 픽쳐 인 픽쳐 제어회로(30)에 인가한다.In the recording mode, the microcomputer 20 checks for the presence of the doorbell output BS (101), and the doorbell output BS has a video camera control signal through the control output terminals C1 and C2 of the microcomputer 20. A picture-in-picture control signal is output and applied to the video camera 10 and the picture-in-picture control circuit 30.
이에 따라 비디오 카메라(10)의 전원이 "온"되어 작동하게 되며(102), 동시에 픽쳐 인 픽쳐 제어회로(30)가 동작하게 된다.Accordingly, the power of the video camera 10 is “on” to operate 102, and at the same time the picture-in-picture control circuit 30 operates.
상기와 같이 작동된 비디오 카메라(10)의 영상출력(VO)은 픽쳐 인 픽쳐 제어회로(30)의 일측 입력에 인가되고(103,) 타측 입력에는 고주파신호(RF)가 입력되어, 두 신호가 합성된 픽쳐 인 칙쳐 제어회로(30)의 출력이 통상의 영상신호처리부(40)를 통해 녹화부(50)에서 픽쳐 인 픽쳐 방식으로 녹화된다.The video output VO of the video camera 10 operated as described above is applied to one input of the picture-in-picture control circuit 30 (103,) and the high frequency signal RF is input to the other input, so that both signals are input. The output of the synthesized picture index control circuit 30 is recorded in a picture-in-picture manner by the recording unit 50 through the normal video signal processing unit 40.
한편, 마이콤(20)에서는 초인종 출력(BS)이 마이콤(20)에 입력되는 시간으로부터 임의로 설정된 시간(t)이 경과되었는지를 체크하여(104) 설정된 시간(t)이 경과하면 픽쳐 인 픽쳐 제어회로(30)를 "오프"시키고(105), 비디오 카메라(10)의 전원을 "오프"시키게 된다(106).On the other hand, the microcomputer 20 checks whether the time t output is arbitrarily set from the time when the doorbell output BS is input to the microcomputer 20 (104), and when the set time t elapses, the picture-in-picture control circuit 30 is “off” 105 and the power of video camera 10 is “off” 106.
이상과 같이 본 고안은, 브이티알의 녹화모우드에서 초인종의 출력을 감지한 후 비디오 카메라를 동작시켜 이 비디오 카메라의 영상출력을 픽쳐 인 픽쳐 방식으로 설정된 일정시간동안 녹화시킴으로서 감시요원이 없어도 초인종 출력에 의해 자동으로 비디오 카메라의 영상출력이 녹화되고, 또한 초인종 출력후의 일정시간동안만 비디오 카메라가 "온"됨에 따라 전력의 낭비를 방지하고 비디오 카메라의 수명의 단축을 방지하는 효과가 있다.As described above, the present invention detects the doorbell's output in VTI's recording mode and operates the video camera to record the video output of the video camera for a certain time set by the picture-in-picture method. As a result, the video output of the video camera is automatically recorded, and the video camera is "on" only for a certain time after the doorbell output, thereby preventing waste of power and shortening the life of the video camera.
