Claims (3)

  1. 단일의 신호 라인을 전송하는 동화 영상 신호의 1 필드 또는 1 프레임을 기억 수단으로 기억시켜 정지화 영상 신호를 형성하여, 상기 동화 영상 신호와 상기 정지 화상 신호를 임의로 발생되는 키 신호에 의거해서 절환하여 합성 영상 신호를 형성하도록 한 영상 신호 처리 장치.
  2. 제1항에 있어서, 상기 기억 수단은 상기 동화 영상 신호가 가산기를 개재하여 공급됨과 함께 그 출력 신호로부터 상기 동화 영상 신호의 감산된 신호가 계수기를 개재하여 상기 가산기에 공급되는 구성으로 하여, 상기한 계수기의 계수를 1 또는 0으로 하므로서 상기 동화 영상 신호와 정지화 영상 신호와의 절환이 행해지도록 한 영상 신호 처리 장치.
  3. 제1항에 있어서, 상기 키 신호는 상기 동화 영상 신호의 1 필드 또는 1 프레임이 메모리에 기입됨과 함께 이 메모리가 독출되어서 형성되도록 한 영상 신호 처리 장치.
    ※ 참고사항 : 최초 출원 내용에 의하여 공개하는 것임.
