Abstract

본 발명은 CRT상에 회상을 형성하기 위한 색차신호의 신호 이득을 조절함으로서 색포화 현상을 억제할 수 있도록 된 색포화 억제회로에 관한것으로서 휘도신호(-Y)와 색차신호(R-Y, B-Y, G-Y)를 근거로 CRT상에 화상을 형성하도록 된 화상형성장치에 있어서 상기 휘도신호(-Y)와 색차신호의 레벨차이를 근거로 상기 색차신호의 레벨을 클램프하는 클램프회로(1)가 갖추어진 것을 특징으로 한다.The present invention relates to a color saturation suppression circuit capable of suppressing color saturation by adjusting a signal gain of a color difference signal for forming a recall on a CRT. In the image forming apparatus configured to form an image on a CRT based on the CRT, a clamp circuit (1) is provided to clamp the level of the color difference signal based on the level difference between the luminance signal (-Y) and the color difference signal. It features.
