Claims (5)

  1. 색도 피킹 회로(58)를 통해 제1비디오 소스(10)에 결합되고, 회로 경로를 통해 제2비디오 소스(64)에 결합된 색도 입력(56)을 갖는 디스플레이 프로세서 (42)를 포함하는 텔레비젼 장치에 있어서, 상기 제2 비디오 소스(64)는 상기 회로(58)경로를 통해 상기 제1비디오 소스(10)가 결합된 상기 제1색도 피킹 회로의 입력에 결합되고, 상기 회로 경로는 상기 제2비디오소스(60)에 의해 제공된 색도 입력 신호를 수신하여 상기 피킹회로(58)에 의해 피킹하고, 디-피킹 회로(80)에 의해 딩-피킹 하는 색도 디-피킹 회로(80)를 포함하는 것을 특징으로 하는 텔레비젼 장치.
  2. 제1형에 있어서, 상기 색도 디-피킹회로(80)는 상기 제2소스에 의해 제공된 상기 색도 신호의 상부와 하부 측대역에 관련된 진폭을 불균형화하는 필터(83)를 포함하는 텔레비젼장치.
  3. 제2항에 있어서, 상기 상부 측대역은 상기 하부 측대역보다 감소되는 텔레비젼 장치.
  4. 제3항에 있어서, 상기 디-피킹 회로의 측대역 감소는 상기 피킹 회로에 의해 제공된 측대역 감소와 실제로 상보되는 텔레비젼장치.
  5. 제1항에 있어서, 상기 디-피킹 회로는 종결 네트워크(81), 측대역 왜곡 필터(83), AC 커필링 네트워크(85)및 스위치 회로(87)를 포함하는 종속 접속으로 되어 있는 텔레비젼장치.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
