Abstract

본 발명은 텔레비젼 영상신호의 색신호, 즉 R, G, B 신호를 선태적으로 제거하여 다양한 색상을 표현할 수 있도록 하기 위한 것으로, 색신호 처리부와 스위칭부 사이에 마이컴으로 부터의 제어신호에 의거하여 R, G, B 신호를 선택적으로 온/오프 제어하는 스위칭수단을 구비함으로서, 흑백과 색상신호의 다양한 조합으로 전형적인 시스템과는 다른 영상을 즐길 수 있도록 한 것이다.The present invention is to provide a variety of colors by selectively removing the color signal, that is, the R, G, B signal of the television video signal, based on the control signal from the microcomputer between the color signal processing unit and the switching unit R, By providing switching means for selectively turning on and off the G and B signals, various combinations of black and white and color signals can be used to enjoy images different from typical systems.

Claims (2)

영상신호를 입력으로 하여 색도신호와 휘도신호로 분리한 다음, 매트릭스를 통해 R, G, B 신호를 발생하는 색신호 처리부와, 이 색신호 처리부로 부터 입력되는 R, G, B 신호를 스위칭하여 CRT상에 출력하는 스위칭부로 이루어진 영상신호의 색신호 제어회로에 있어서, 상기 색신호 처리부와 스위칭부 사이에 접속되고, 마이컴으로 부터의 제어신호에 의거하여 R, G, B 신호를 선택적으로 온/오프 제어하는 스위칭 수단을 더욱 포함하여 이루어진 것을 특징으로 하는 영상신호의 색신호 제어회로.The video signal is input and separated into a chromaticity signal and a luminance signal. Then, the color signal processor generates R, G, and B signals through a matrix, and the R, G, B signals inputted from the color signal processor switch to switch the CRT image. In a color signal control circuit of a video signal comprising a switching unit for outputting to the switching unit, the switching unit is connected between the color signal processing unit and the switching unit and selectively switches on / off the R, G, and B signals based on a control signal from a microcomputer. Color signal control circuit of a video signal characterized in that it further comprises a means. 제 1 항에 있어서, 상기 스위칭수단은 상기 색신호 처리부로 부터 출력되는 R, G, B 신호에 대응하는 3개의 트랜지스터로 구성된 것을 특징으로 하는 영상신호의 색신호 제어회로.2. The color signal control circuit of claim 1, wherein the switching means comprises three transistors corresponding to R, G, and B signals output from the color signal processor. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
