Claims (5)
- 보간된 영상신호와 원래의 영상신호를 선택적으로 출력하여 비월주사되어 수신된 신호를 순차주사신호로 출력하는 비월주사신호/순차주사신호 변환회로에 있어서, 원 신호에서 지역 성분만을 제거하기 위한 N차 콤필터; 상기 N차 콤필터의 중간차수 지연 출력 신호에서 상기 N차 콤필터의 최종 출력 신호를 빼는 감산기; 상기 N차 콤필터를 통과한 소정의 이득값으로 증폭시키기 위한 이득 조정기; 상기 이득 조정기를 통해 증폭된 신호와 상기 감산기를 통과한 신호를 더하는 가산기를 포함함을 특징으로 하는 광대역 비월주사신호/순차주사신호 변환회로.
- 제1항에 있어서, 상기 보간부는, 저역 성분은 선간 보간을 하고, 고역 성분은 '0'을 삽입하는 것을 특징으로 하는 광대역 비월주사신호/순차주사신호 변환회로.
- 제1항에 있어서, 상기 감산기의 상기 N차 콤필터의 중간차수지연 출력 신호는 상기N차 콤필터의 최종 출력신호와 지연 시간을 일치시키게 설정함을 특징으로 하는 광대역 비월주사신호/순차주사신호 변환회로.
- 제1항 또는 제3항에 있어서, 상기 N차 콤필터는 2차 콤필터로, 상기 중간차수 지연 출력 신호는 1차 지연 신호로 설정함을 특징으로 하는 광대역 비월사주사신호/순차주사신호 변환회로.
- 제1항에 있어서, 상기 이득 조정기는 상기 소정의 이득값을 외부에서 사용자가 조정할 수 볼륨을 포함함을 특징으로 하는 광대역 비월주사신호/순차주사신호 변환회로.
