Abstract

촬상시에 각 컷을 대표하는 정지화 데이터를 어드레스 정보와 함께 자동적으로 기록한다.
카메라부(1)로 부터의 비디오신호 SV를 동화 데이터로서 동화기록부(2)에 공급한다. 동화기록부(2)에서는 비디오신호 SV를 동화데이터로서 동화기록부(2)에 공급한다. 동화기록부(2)에서는 비디오신호 SV에 타임코드를 부가하여 기록한다.
카메라부(1)로부터의 비디오신호 SV를 프레임 메모리(4) 및 (5)의 직렬 회로에 공급한다. 각 프레임마다에 메모리(4), (5)에서 비디오신호를 독출하여 비교연산부(6)에 공급한다. 비교연산부(6)에서는 1프레임의 시간차를 가지는 비디오신호를 비교연산(상관판정)하는 것에서 신변화를 검출하고 그 신변화 검출 정보를 콘트롤러(3)에 공급한다. 신 변화시에는 컨트롤러(3)의 제어에 의거해서 메모리(5)에서 1프레임분의 비디오신호를 독출하고 정지화 데이터로서 정지화기록부(7)에 공급하여 기록한다. 이때 그 1프레임분의 비디오신호가 동화기록부(2)에서 기록될때에 부여되는 타임코드를 함께 기록한다.
