Claims (4)
- 최소한 1개의 라인 지연 수단을 갖고서 라인 상관을 이용하여 제1휘도 신호 및 제1 색신호를 얻는 제1YC분리회로, 최소한 1개의 프레임 지연 수단을 갖고서 플레임 상관을 이용하여 제2휘도 신호 및 제2 색신호를 얻는 제2YC 분리회로, 화상의 움직임을 검출하는 움직임 검출 회로, 및 이 움직임 검출 회로의 출력에 의해 상기 제1 및 제2 휘도 신호의 혼합비 및 상기 제1 및 제2 색신호의 혼합비가 제어되는 혼합 회로를 구비한 텔레비젼 수상기에 있어서, 정지 화상의 재생 지령에 따라서 제어 신호를 발생시키는 제어 신호 발생 회로, 및 제어 시호에 의해 제어되며, 상기 플레임 지연 수단의 출력을 순회시키는 순회 회로를 형성하는 스위치 회로로 이루어지고, 정지 화상 재생시에 순회 경로에서 인출된 출력에 기초를 두고 YC분리를 행하는 것을 특징으로 하는 텔레비젼 수상기.
- 제1항에 있어서, 정지 화상 재생시에, 상기 혼합 회로가 제어 신호에 의해 제어되고, 상기 제1휘도 신호 및 제1색 신호만을 선택 출력시키는 것을 특징으로 하는 텔레비젼 수상기.
- 제1항에 있어서, 정지 화상 재생시에, 상기 제어 신호에 의해 제어되고, 혼합 회로로부터의 색신호 출력을 1플레임마다 반전시키는 크로마 인버터 회로가 설치되는 것을 특징으로 하는 것을 특징으로 하는 텔레비젼 수상기.
- 제3항에 있어서, 상기 스위치 회로의 전환 및 상기 크로마 인버터 회로의 반전이 수직 블랭킹 기간내에서 행해지는 것을 특징으로 하는 텔레비젼 수상기.
