Abstract
본 발명은 영상처리기기에 있어서 색동기신호 안정화 방법 및 그에 적합한 회로에 관한 것으로, 특히 복합동기신호를 입력하여 상기 복합동기신호로부터 수평공기신호를 분리하는 수평동기분리부; 상기 복합 동기신호로부터 분리된 수평동기신호와 위상이 동기된 색동기신호를 출력하는 위상제어루프; 및 NTSC 다지털성분 영상신호로부터 생성된 아날로그성분 영상신호에 상기 위상제어루프에서 출력된 색동기신호를 합성하여 아날로그 복합영상신호를 출력하는 NTSC 인코딩부를 포함한다. 따라서, 본 발명은 복합동기신호에서 수평동기시호를 분리하여 수평동기신호와 색동기시호의 주파수를 이용해서 수평동기신호에 색동기신호의 위상을 동기시킴으로써, 색동기신호의 위상을 일정하게 유지하는 효과가 있다.The present invention relates to a color synchronization signal stabilization method and a suitable circuit in the image processing device, and in particular, a horizontal synchronous separation unit for inputting a composite synchronous signal to separate the horizontal air signal from the composite synchronous signal; A phase control loop for outputting a color synchronization signal whose phase is synchronized with the horizontal synchronization signal separated from the complex synchronization signal; And an NTSC encoding unit for synthesizing the color synchronizing signal output from the phase control loop to the analog component video signal generated from the NTSC digital component video signal and outputting the analog composite video signal. Accordingly, the present invention separates the horizontal synchronization signal from the composite synchronization signal and synchronizes the phase of the color synchronization signal to the horizontal synchronization signal using the frequency of the horizontal synchronization signal and the color synchronization signal, thereby keeping the phase of the color synchronization signal constant. It works.
