Abstract
본 발명은 VCR의 재생 장치에 관한 것으로, 통상의 VCR에 있어서, 비디오 헤드로부터 입력된 아날로그 신호를 디지탈 신호로 변환하는 A/D 컨버터(10)와; 상기 디지탈 신호를 저장하는 프레임 메모리(20) , 상기 프레임 메모리(20)의 디지탈 신호를 입력받아 아날로그 신호로 변환하여 영상처리 회로로 출력하는 D/A 컨버터(30); 상기 프레임 메모리(20)의 리드 및 라이트 동작을 제어하여 스틸 조작시에 라이트 동작을 멈춘 채 프레임 메모리(20)에 저장된 최종 프레임의 영상 신호만을 반복하여 리드하도록 제어하는 제어부(40)로 구성되어 있으며, 상기와 같이 구성된 본 발명의 장치는 헤드로부터 영상 신호를 읽어, 영상처리를 하기 전에 메모리에 한번 저장하였다가 출력함으로써, 스틸 재생시 최종 저장된 프레임만을 반복 재생하여 원하는 화면을 흔들림 없이 정확하게 재생할 수 있다는 데 그 이점이 있다.The present invention relates to a playback device of a VCR, comprising: an A / D converter (10) for converting an analog signal input from a video head into a digital signal; A frame memory 20 for storing the digital signal, a D / A converter 30 for receiving a digital signal of the frame memory 20, converting the digital signal into an analog signal, and outputting the analog signal to an image processing circuit; The controller 40 is configured to control read and write operations of the frame memory 20 to repeatedly read only the image signal of the last frame stored in the frame memory 20 while stopping the write operation during the still operation. The apparatus of the present invention configured as described above reads a video signal from a head, stores it once in a memory before outputting the image, and outputs the same, thereby reproducing only the last stored frame during still playback to accurately reproduce a desired screen without shaking. There is an advantage to having it.
