Abstract
본 발명은 감시용 카메라 시스템에 관한 것으로서, 특정 장소의 피사체를 촬상하여, 영상 신호로 출력하는 카메라부(10)와, 상기 카메리부(10)로부터의 영상 신호를 기록 가능한 신호로 처리하는 신호처리부(20)와, 상기 카메라부(10)로부터의 영상 신호를 디지털화하여 프레임단위로 저장하는 저장 회로(40)와; 상기 저장 회로(30)에 저장된 영상 신호 값과 소정의 기준 영상 값과 변화량을 검출하여 검출된 변화량이 소정의 임계 값이상일 때에 녹화 제어신호를 출력하는 변화량 검출부(50)와; 녹화 제어 신호의 인가시에 구동하여 상기 신호 처리부(20)로부터 처리된 영상 신호를 비디오 테이프에 기록하는 데크부(30)를 구비한다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a surveillance camera system, comprising: a camera unit (10) for capturing a subject in a specific place and outputting the video signal as a video signal; and a signal for processing the video signal from the camera unit (10) as a recordable signal. A processing circuit 20 and a storage circuit 40 for digitizing and storing image signals from the camera unit 10 frame by frame; A change amount detector (50) for detecting a video signal value stored in the storage circuit (30), a predetermined reference video value, and a change amount and outputting a recording control signal when the detected change amount is equal to or greater than a predetermined threshold value; And a deck unit 30 for driving the recording control signal to record the video signal processed by the signal processing unit 20 on a video tape.
따라서, 본 발명은 감시하고자 하는 장소에서 피사체의 변동이 발생된 경우에만 녹화 모드로 구동하게 되어 재생시 화면의 선명도를 유지할 수 있고 장시간 기록도 가능한 효과가 있다.Therefore, the present invention operates in the recording mode only when the subject changes in the place to be monitored, so that the sharpness of the screen can be maintained during reproduction and recording can be performed for a long time.
