Claims (1)

백색성분을 중심으로 검출할 수가 있는 백색검출수단과, 살색성분을 중심으로 검출할 수 있는 살색검출 수단의 각각에 3원색 신호가 공급되는 다이나믹 칼라보정회로에 있어서, 상기 백색검출수단에서 얻어지는 살색검출 출력과 살색검출수단으로 얻어지는 살색검출 출력이 감산기에 공급되어서 백색인때에 최대이고, 백색에서 벗어남에 따라서 그 레벨이 저하함과 동시에, 살색인때에 그 레벨이 영으로 되는 보정출력이 얻어지고, 이 보정출력으로 R,G,B 채널중의 특정한 채널의 색신호를 보정하도록 한 다이나믹 칼라 보정회로.In a dynamic color correction circuit in which three primary color signals are supplied to each of the white detection means capable of detecting mainly white components and the flesh color detection means capable of detecting mainly white components, the flesh color detection obtained in the white detection means. The output of the skin and the color detection output obtained by the skin color detecting means are supplied to the subtractor, which is the maximum when it is white, and the level decreases as it leaves the white color. And a dynamic color correction circuit for correcting a color signal of a specific channel among the R, G, and B channels with this correction output. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
