Claims (2)
- 영상신호로부터 분리된 동기신호를 입력받아 수직리셋신호와 수평리셋신호를 동기신호발생부로 출력하는 트리거보드의 리셋신호제어장치에 있어서, 상기 장치가 상기 동기신호발생부로부터 출력된 색부반송파의 위상과 영상신호로부터 분리된 색부반송파의 위상을 비교하는 위상비교부와, 상기 위상비교부로부터 위상일치신호가 입력되면 내부 카운터로 입력되는 영상신호로부터 분리된 수직동기신호를 업카운팅하여 일정값으로 카운팅될때마다 리셋신호발생부로 리셋출력신호를 출력하는 카운터부와, 상기 위상비교부로부터 위상일치신호가 입력되기전에는 매 필드신호의 입력시마다 수직동기리셋신호를 출력하고, 상기 위상비교부로부터 위상일치신호가 입력되면 상기 카운터부로부터 리셋출력신호가 입력될 때마다 수직동기리셋신호를 출력하는 리셋신호발생부를 구비함을 특징으로 하는 트리거보드의 리셋신호제어장치.
- 제1항에 있어서, 상기 카운터부가 동일한 위상이 반복되는 필드의 2~4배마다 리셋출력신호를 출력하도록 동작함을 특징으로 하는 트리거보드의 리셋신호제어장치.
