Abstract

이 발명은 입력되는 영상신호가 처리되어 표시되는 예를들어 텔레비젼, 비디오 테이프 레고더, 비디오 카메라와 같은 모든 영상처리 시스템에 관한것으로써, 입력되는 영상신호가 기록 및 재생되는 비디오 테이프 레코더에 있어서, 스위칭 제어수단(10),제1스위칭(20), 메모리 제어수단(30)와, 메모리(35),제2스위치(40)로 구성되어 재생모우드와 특정화면 표시모우드가 동시에 선택되는 경우 입력되는 영상신호가 그대로 화면에 디스플레이되고, 재생모우드만이 선택되는 경우 한 필드 또는 한 프레임분의 영상신호의 기록과 동시에 이미 저장된 영상신호가 화면에 디스플레이되며, 도한 재생모우드 및 특정화면 표시모우드가 선택되지 않는 경우 이미 기록된 영상신호가 화면에 디스플레이됨으로써, 기존의 무신호 입력시 한가시 색상으로 화면에 디스프레이되던 것이 다양한 화면으로 표시되고 각종 모우드가 실행되기 이전의 대기상태동안 디스플레이되는 노이즈 성분이 제거되어 깨끗한 화질을 구현할 수 있다.The present invention relates to all image processing systems such as televisions, video tape recorders, video cameras, in which the input video signal is processed and displayed, and in the video tape recorder in which the input video signal is recorded and reproduced, It is composed of the switching control means 10, the first switching 20, the memory control means 30, the memory 35, the second switch 40 is input when the playback mode and the specific screen display mode is selected at the same time When the video signal is displayed on the screen as it is and only the playback mode is selected, the video signal already stored is displayed on the screen at the same time as the recording of one field or one frame of video signal, and the playback mode and the specific screen display mode are not selected. If not, the recorded video signal is displayed on the screen. Is displayed in various screen to release and remove the noise component The mode is to be displayed during the previous idle state of the runs may implement a clear picture.
