Description

텔레비전의 수직 윤곽 보정회로Vertical contour correction circuit of television

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 본 발명에 따른 수직 윤곽 보정회로의 구성도,1 is a block diagram of a vertical contour correction circuit according to the present invention,

제2도는 입력신호의 샘플링상태 및 화면상태도,2 is a sampling state and a screen state diagram of an input signal;

제3도는 수직윤곽이 보정된 신호의 샘플링 상태도.3 is a sampling state diagram of a signal whose vertical outline is corrected.

Claims (1)

텔레비전의 수직 윤곽 보정회로에 있어서, 아날로그 영상신호를 디지털 영상신호로 변환하는 D/A변환수단과 상기 디지털 영상신호를 1수평동기 주기씩 지연하여 제1 및 제2 지연신호를 발생하는 지연수단과, 현입력신호 및 상기 제1 및 제2 지연신호룰 소정증폭하는 증폭수단과, 상기 증폭수단의 출력에서 제1지연신호를 기준으로 현입력신호 및 제2 지연신호를 감산하여 제1윤곽 보정신호를 발생하는 제1가산수단과, 상기 제1지연신호와 상기 제1윤곽 보정신호를 가산하여 수직 윤곽이 보정된 신호를 발생하는 제2가산수단과, 상기 제2가산수단의 출력을 아날로그 변환하여 출력하는 D/A변환 수단으로 구성됨을 특징으로 하는 텔레비전의 수직 윤곽 보정회로.A vertical contour correction circuit of a television, comprising: D / A conversion means for converting an analog video signal into a digital video signal, and delay means for delaying the digital video signal by one horizontal synchronization period to generate first and second delay signals; A first contour correction signal by subtracting the current input signal and the second delay signal based on the first delay signal from the output of the amplification means; A first addition means for generating a second, second addition means for generating a signal whose vertical contour is corrected by adding the first delay signal and the first contour correction signal, and an analog conversion of an output of the second addition means A vertical outline correction circuit of a television, characterized in that it comprises an output D / A conversion means. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
