Abstract
본 발명은 입력되는 영상신흥원에 포함된 노이즈레벨에 따라 화질처리회로의 피이크량을 자동으로 보정할 수 있도록 한 텔레비젼 수상기의 자동화질보정회로에 관한 것이다. 본 발명의 텔레비젼 수상기의 자동화질보정회로는 설정전압에 의하여 설정된 전압값에 의거하여 영상신호에서 분리된 휘도신호의 화질을 보정하는 화질 처리수단을 구비한 텔레비젼 수상기에 있어서, 휘도신호에 포함된 고역성분의 노이즈레벨을 검출하는 노이즈 검출수단 및 노이즈 검출수단으로부터 검출된 노이즈의 레벨이 소정의 기준치이상인 경우에는 노이즈의 레벨에 비례하여 상기 화질처리수단에 제공되는 설정전압의 크기를 감소시키는 설정전압 가변수단을 구비한 것을 특징으로 한다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic quality correction circuit for a television receiver, which is capable of automatically correcting the peak amount of an image quality processing circuit according to an input noise level included in an image emerging source. The automatic quality correction circuit of a television receiver according to the present invention is a television receiver having image quality processing means for correcting image quality of a luminance signal separated from an image signal based on a voltage value set by a set voltage, wherein the high frequency range included in the luminance signal is included. When the level of noise detected by the noise detecting means for detecting the noise level of the component and the noise detected by the noise detecting means is greater than or equal to a predetermined reference value, the setting voltage variable to reduce the magnitude of the set voltage provided to the image quality processing means in proportion to the level of the noise. It is characterized by having a means.
