Abstract
본 발명은 영상신호에 포함된 최초 수직동기신호를 검출하고 이 검출된 동기신호에 일치시켜 영상신호를 처리하도록 한 최초 수직동기신호 검출장치에 관한 것으로, 이를 해결하기 위하여 안테나로부터 수신되는 복합영상신호를 영상신호와 동기신호로 분리하는 동기신호 분리부, 이 분리된 신호중 영상신호를 디지탈신호로 변환하는 A/D 변환부, 이 디지탈신호를 저장하는 필드 메모리 및 기본 클럭 및 어드레스 데이터를 제공하는 장치를 구비한 디지탈 영상처리 장치에 있어서: 동기신호 분리부로부터 분리되는 수직동기신호중 최초의 수직동기신호가 검출되면, 이 검출된 시점을 근거로 상기 A/D 변환부에 의해 변환된 디지탈신호가 필드 메모리에 저장되도록 소정의 제어신호를 인가하는 최초 수직동기 검출부로 이루어진다.The present invention relates to a first vertical synchronous signal detecting apparatus for detecting an initial vertical synchronous signal included in a video signal and processing the video signal by matching the detected synchronous signal. To solve this problem, a composite video signal received from an antenna is provided. A synchronizing signal separating unit for dividing the video signal into a synchronizing signal, an A / D converter for converting the video signal into a digital signal among the separated signals, a field memory for storing the digital signal, and an apparatus for providing basic clock and address data A digital image processing apparatus having: a digital signal converted by the A / D converter based on the detected time point when a first vertical synchronous signal is detected among the vertical synchronous signals separated from the synchronous signal separator; It consists of an initial vertical synchronization detector for applying a predetermined control signal to be stored in the memory.
