Claims (1)

디지털 영상신호의 수평 및 수직 윤곽 보장 장치의 코어링 회로에 있어서, 코어링 데이터 데드죤 설정 데이터(Dc)를 입력하열 휘도 신호(Y)를 밴드패스 필터링한 신호(Xi)의 부호비트 상태에 따라 상기 코어링 데이터(Dc)와 상기 코어링 데이터(Dc)의 반전신호를 선택적으로 출력하는 선택부(10)와, 상기 선택부(10) 출력과 상기 필터링 신호(Xi)를 감산하는 감산부(200)와, 상기 감산부(200) 출력과 상기 필터링 신호(xi)부호 비트를 입력하여 배타적 논리합하는 논리수단(300)과, 상기 논리수단(300) 출력과 상기 감산부(200)의 n비트 출력을 각각 논리곱하여 코어링 회로 출력(x0)를 출력하는 출력부(400)로 구성됨을 특징으로 하는 회로.In a coring circuit of a horizontal and vertical contour guarantee device of a digital video signal, the coring data dead zone setting data (Dc) is input according to the code bit state of the signal Xi obtained by bandpass filtering the luminance signal (Y). A selection unit 10 selectively outputting the coring data Dc and an inverted signal of the coring data Dc, and a subtraction unit subtracting the output of the selecting unit 10 and the filtering signal Xi; 200, logic means 300 for exclusively ORing the subtracter 200 output and the filtering signal xi code bits, and the n bits of the logic means 300 output and the subtractor 200. And an output unit (400) for outputting the coring circuit output (x0) by logically multiplying the outputs. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
