- 복합영상신호로 부터 분리된 휘도신(Y)호와 색신호(C)를 각각 받아 색차신호(B-Y)(R-Y)를 만들어 출력하고 동시에 주변저항소자의 설정값에 따라 출력 색차신호의 색상 및 포화도를 조절하여 출력하는 다수개의 칼라 디코더와, 상기 칼라 디코더에서 출력되는 색차신호와 기준신호를 비교하여 살색신호 포함여부를 판단하는 비교부와, 상기 비교부 부터 출력되는 신호를 받아서 살색으로 판정되면 미리 설정된 보정값으로 보정동작을 수행하는 마이크로컴퓨터로 구성된 것을 특징으로 하는 색보상 장치.
- 제1항에 있어서, 주변저항소자는 하나의 칼라 디코더의 색차신호로 부터 검출하고자 하는 색과 그 주변색을 포함한 색을 검출할 수 있도록 저항값을 조정하고, 다른 하나의 칼라 디코더의 색차신호로 부터 검출하고자 하는 색상의 색차신호의 중심전압에 일치하도록 저항값을 조정하도록 한 것을 특징으로 하는 색보상 장치.
