Abstract

본 발명은 방송수신모드와 외부영상 수신모드간의 색신호의 진폭이 차이를 자동으로 보상하므로써 수신모드의 절환에 관계없이 균일한 색농도를 가지는 화상을 재현할 수 있도록 한 텔레비젼 수상기의 색신호이득 자동 조정회로에 관한 것이다. 본 발명은 방송수신모드와 외부영상 수신모드사이의 절환이 가능하고, 상기 수신모드의 절환시 TV자체에서 제공되는 영상신호와 외부영상기기에서 제공되는 영상신호를 선택적으로 처리하여 컬러화상으로 재현할 수 있도록 된 텔레비젼 수상기에 있어서, 상기 각각의 영상신호에서 분리되는 색신호의 이득을 조정하는 수단 및 외부영상 수신모드에 있어서의 색신호의 진폭과 동일하도록 상기 이득조정수단의 이득비를 제어하는 수단을 구비한 것을 특징으로 한다.The present invention automatically compensates for the difference in the amplitude of color signals between the broadcast receiving mode and the external video receiving mode, so that the color signal gain automatic adjustment circuit of a television receiver can reproduce an image having a uniform color intensity regardless of the switching of the receiving modes. It is about. The present invention is capable of switching between a broadcast receiving mode and an external video receiving mode, and selectively converts a video signal provided from the TV itself and a video signal provided from an external video device to reproduce the color image. A television receiver, comprising: means for adjusting a gain of a color signal separated from each video signal and means for controlling a gain ratio of the gain adjusting means to be equal to an amplitude of a color signal in an external video reception mode. It is characterized by one.
