Claims (1)

입력 영상신호의 1차 미분신호를 소정시간차를 두고 절대치화 하여 2차 미분신호를 소정 레벨 제한 증폭한 값과 승산한 후 원래의 입력 영상신호의 가산하는 수평 윤곽 인핸싱 방법에 있어서, 상기 소정시간 차를 갖는 절대치 값들을 상호 비교하여 최소값을 선택함으로써 상기 2차 미분 신호를 소정제한 증폭한 값에 상기 1차 미분신호를 리쉐이핑 하여 승산토록 함을 특징으로 하는 수평 윤곽 인핸싱방법.A horizontal contour enhancement method of adding an original input video signal after multiplying a first differential signal of an input video signal by an absolute value with a predetermined time difference and multiplying a second differential signal by a predetermined level limited amplification value. And reshaping the first derivative signal to multiply the second differential signal by a predetermined limited amplification by selecting a minimum value by comparing absolute values having a difference with each other. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
