Claims (3)
- 제1 및 제2가산기(10, 30)와 승산기(20)를 구비한 동작 적응형 색합성회로(100)에 있어서, 프레임 콤 처리된 색신호(CF)를 소정대역으로 필터링하는 밴드패스필터(300)와, 상기 밴드패스필터(300) 출력(CFB)과 상기 프레임 콤 처리된 색신호(CF)를 움직임량에 따라 선택적으로 출력하여 상기 동작 적응형 색합성부(100)의 제1 및 제2가산기(10, 30)의 타단으로 인가하는 멀티플렉서(200)로 구성됨을 특징으로 하는 적응형 색신호 합성회로.
- 제1항에 있어서, 상기 멀티플렉서(200)를 선택단으로 인가되는 동작인자의 상태가 준동화를 의미할 시 프레임콤 처리된 색신호를 밴드 패스 필터링한 신호를 출력하며, 동화를 의미할 시에는 순수 프레임 콤 처리된 색신호를 그대로 출력하도록 구성함을 특징으로 하는 동작적응형 색신호 합성회로.
- 동작적응형 색 신호 합성방법에 있어서, 준동화시 프레임 콤 처리된 색신호를 밴드패스 필터링한 신호를 선택하며, 완전정지시는 프레임콤 처리된 색신호를 선택하여 라인 콤 처리된 색신호와 합성함을 특징으로 하는 동작적응형 색신호 합성방법.※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
