Claims (2)

  1. 원색신호 또는 색차신호로부터 색포화도를 검출하는 색포화도 검출수단이 설치되며, 석포화도가 낮을 때는 상기 원석신호 또는 석차신호는 그대로 출력되고, 색포화도가 높을 때는 표시화면 상에서 최소한 청색성분을 증가시키도록 보정되는 것을 특징으로 하는 컬러텔레비젼 수상기.
  2. 색포화도의 검출수단으로서 적색, 청색 및 녹색의 원색신호 또는 색차신호 중 최소 레벨을 검출하는 수단이 설치되며, 그 검출레벨에 의해 그 검출레벨이 낮아질수록 최소한 청색분을 증가시키도록 보정되는 것을 특징으로 하는 특허청구의 범위 1기재의 컬러텔레비젼 수상기.
