The sample / hold and color separation circuit 3 converts the electrical analog signal into a voltage maintaining a constant level and separates it into a luminance signal and a color signal. The luminance signal processing circuit 4 processes the luminance signal, displays it on the CRT monitor unit 5, and supplies the luminance signal to the mixer circuit 6 that sums the luminance signal and the color signal. The color signal processing circuit 7 processes the color signal and supplies it to the mixer circuit 6 which sums up the luminance signal and the color signal. The luminance signal and the color signal are mixed to output a color image signal. The modulation circuit 8 modulates the color image signal and supplies a signal to the tech circuit 9 to be recorded on the tape. The control circuit 10 provides the appropriate timing for operating the circuits.

제2도에 있어서, 렌지(1a)와 조리개(1b)를 통하여 빛이 들어오면, 전하결합소자(2)는 광신호를 전기적인 아날로그신호로 바꾸어 준다. 샘플/홀드 및 색분리회로(3)는 상기 전기적인 아날로그신호를 일정한 레벨을 유지하는 전압으로 변환하고 휘도신호와 색신호로 분리한다. 휘도신호처리회로(4)는 상기 휘도신호를 처리해서 CRT 모니터부(5)에 디스플레이하고 휘도신호와 색신호를 합하는 믹서회로(7)에 공급한다. 색신호처리회로(7)는 상기 색신호를 처리해서 휘도신호와 색신호를 합하는 믹서회로(6)에 공급한다. 휘도신호와 색신호를 혼합하여 컬러화상신호를 출력한다. 믹서회로(6)는 휘도신호와 색신호를 혼합하여 컬러화상신호를 출력한다. 변조회로(8)는 기록시에 스위치(S2)를 점(R) 위치에 놓으면 상기 컬러화상신호를 변조한 테이프에 기록할 신호를 데크회로(9)에 공급한다. 그리고 기록시에 스위치(S1)을 점(R) 위치에 놓으면 믹서회로(6)는 휘도신호와 색신호를 합하여 그 출력신호가 액정표시장치(11)에 공급하여 기록시에 영상을 칼라로 볼 수가 있다. 복조회로(12)는 재생시에 스위치(S1,S2)를 점(P) 위치에 놓으면 데크회로(9)의 신호를 입력하여 복조해서 액정표시장치(11)에 공급하여 칼라로 재생되는 영상을 볼 수가 있다.In FIG. 2, when light enters through the range 1a and the stop 1b, the charge coupling element 2 converts the optical signal into an electrical analog signal. The sample / hold and color separation circuit 3 converts the electrical analog signal into a voltage maintaining a constant level and separates it into a luminance signal and a color signal. The luminance signal processing circuit 4 processes the luminance signal, displays it on the CRT monitor section 5, and supplies the luminance signal to the mixer circuit 7 that sums the luminance signal and the color signal. The color signal processing circuit 7 processes the color signal and supplies it to the mixer circuit 6 which sums up the luminance signal and the color signal. The luminance signal and the color signal are mixed to output a color image signal. The mixer circuit 6 outputs a color image signal by mixing the luminance signal and the color signal. The modulation circuit 8 supplies the deck circuit 9 with a signal to be recorded on the tape modulated with the color image signal when the switch S2 is placed at the point R at the time of recording. When the switch S1 is placed at the point R during recording, the mixer circuit 6 adds the luminance signal and the color signal, and the output signal is supplied to the liquid crystal display device 11 so that the image can be viewed in color at the time of recording. have. When the demodulation circuit 12 sets the switches S1 and S2 at the point P at the time of reproduction, the demodulation circuit 12 inputs and demodulates the signal of the deck circuit 9 to supply the liquid crystal display device 11 to reproduce the image reproduced in color. I can see it.
