Abstract

본 발명은 화질의 저하를 방지할 수 있도록 된 배주사 방식 텔레비젼 수상기에 관한 것으로서, 비월주사 방식의 텔레비젼 신호를 보간신호를 삽입하여 배주사 하도록 된 텔레비젼 수상기에 있어서, 검파된 영상신호의 휘도신호(Y)를 근거로 화상이 정지화상인지 동화상인지를 검출하는 모션 검출수단(31)과, 보간주사시에 상기 모션 검출수단(31)에 의한 검출결과에 따라 휘도신호(Y)의 산술평균처리를 선택적으로 실행하는 산술평균수단(32) 및, 색차신호를 배주사 변환하는 배주사 변환 수단을 포함하여 구성된 것을 특징으로 한다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a television type television receiver capable of preventing deterioration in image quality. The present invention relates to a television receiver configured to insert and interpolate an interlaced television signal by interpolation. Motion detection means 31 for detecting whether the image is a still image or a moving image based on Y), and arithmetic average processing of the luminance signal Y in accordance with the detection result by the motion detection means 31 during interpolation scanning. And an arithmetic mean converting means 32 for selectively executing, and a multiplying scanning converting means for performing a multi-scanning conversion of the color difference signal.
