Claims (3)
- 영상신호를 유입하여 휘도/색신호를 분리해 내기 위한 휘도/색신호 분리회로를 구비한 영상처리회로에 있어서, 상기 휘도/색도신호분리회로에서 출력된 휘도신후중 동기신호의 부분만 추출해 위상이 반전된 동기신호를 출력하는 동기신호추출부와, 상기 동기신호추출부의 위상 반전된 동기신호를 전송하는 제 1 버퍼와, 상기 휘도/색도신호분리회로에서 출력된 휘도신호를 전송하는 제 2 버퍼와, 상기 제 1 버퍼에서 출력되는 위상반전된 동기신호와 상기 제 2 버퍼에서 출력되는 원위상의 동기신호를 가진 휘도신호가 가산되어 동기신호가 제거된 휘도신호만 출력되는 출력단자를 포함함을 특징으로 하는 휘도신호분리회로.
- 제 1 항에 있어서, 상기 동기신호추출부는 상기 휘도/색도신호분리회로에서 출력된 휘도신호중 페데스탈레벨을 가지는 기준전압발생수단을 포함함을 특징으로 하는 휘도신호분리회로.
- 제 2 항에 있어서, 상기 제 1,2버퍼는 각각 팔로워의 구성으로 이루어진 것을 특징으로 하는 휘도신호분리회로.
