Abstract

본 발명은 영상신호 처리기의 수직 윤곽 보정에 관한 것으로, 1H 지연된 피사체 경계면의 라인신호는 1H 지연되기 이전 라인의 신호(PS)가 합성되어지고, 그 다음 라인의 신호는 상기 라인신호(PS) 이전의 라인신호(PS+1)가 합성되게 함으로써 전체적으로 피사체 경계면 상, 하의 각 라인에 수직 윤곽 보정신호가 인가되어 1 수평라인 지연기를 이용하여 370 티 브이 라인 정도의 수직 해상도를 400 티 브이 라인 정도의 수직 해상도를 갖게 할 수 있다.The present invention relates to the correction of the vertical contour of the image signal processor, wherein the line signal of the object boundary delayed by 1H is combined with the signal PS of the line before the delay of 1H, and the signal of the next line is before the line signal PS. By synthesizing the line signals PS + 1, the vertical contour correction signal is applied to each line above and below the subject boundary as a whole. Using a horizontal line delayer, a vertical resolution of about 370 TV lines is about 400 TV lines. Can have vertical resolution.
