Claims (2)

촬상부로부터의 신호를 라인 메모리에 공급하여, 이 라인 메모리에서 얻어지는 지연 신호에 의거하여 휘도 신호와 반송색 신호를 형성하여, 휘도 신호는 그대로 출력하여, 반송색 신호는 엔코더를 거쳐서 출력하는 카메라 신호 처리계와, 자기 헤드에 의해 기록 매체를 주사하여 얻어지는 인접 트랙으로부터의 크로스토크 성분을 포함하는 재생 휘도신호와 재생 반송색 신호를 분리하여, 상기 재생 휘도 신호는 복조하여, 상기 재생 반송색 신호는 디코드하여 이 재생 휘도 신호와 재생 반송색 신호의 최소한 한편을 상기라인 메모리에 공급하여 상기 크로스토크 성분을 제거하여 이 재생 휘도 신호는 그대로, 이 재생 반송색 신호는 상기 엔코더를 거쳐서 출력하는 재생 신호 처리계를 구비하여 형성되는 것을 특징으로 하는 칼라 영상신호의 처리장치.The signal from the image pickup unit is supplied to the line memory, and the luminance signal and the carrier color signal are formed based on the delay signal obtained from the line memory, and the luminance signal is output as it is, and the carrier color signal is output through the encoder. A reproduction luminance signal and a reproduction carrier color signal including a crosstalk component from adjacent tracks obtained by scanning a recording medium by a magnetic head and a processing system are separated, and the reproduction luminance signal is demodulated, so that the reproduction carrier color signal is obtained. Decode and supply at least one of the reproduction luminance signal and the reproduction carrier color signal to the line memory to remove the crosstalk component so that the reproduction luminance signal is output as it is, and the reproduction carrier color signal is output through the encoder. Color image signal processing apparatus, characterized in that it comprises a system. 제1항에 있어서, 상기 카메라 신호 처리계의 엔코더에서 기록시 상기 반송색 신호로 저역 변환 캐리어 신호를 변조하도록 한 것을 특징으로 하는 칼라 영상신호의 처리장치.2. The apparatus of claim 1, wherein the low-frequency conversion carrier signal is modulated by the carrier color signal during recording by the encoder of the camera signal processing system. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
