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

본 발명의 일실시예에 의한 수직 상세 강조 시스템과 상호 작동하는 칼라텔레비전의 부분들을 도시한 개략도.Schematic diagram showing portions of a color television cooperating with a vertical detail highlighting system according to one embodiment of the invention.

Claims (1)

본문에 설명되고 도면에서 도시한 바와 같이 전류라인 비데오 신호와 선행라인 비데오 신호들의 합을 나타내는 출력을 제공하는 제11-H형 빗살형 필터와 전류라인 비레오 신호들과 선행라인 비데오신호들 사이의 차이를 나타내는 출력을 제공하는 제21-H형 빗살형 필터와, 신호가산기와, 주어진 극성을 갖는 상기 가산기에로 상기 합한 표현출력을 인가하기 위하여 상기 제1빗살형 필터와 상기 가산기 사이에 연결된 주어진 이득과 통과 대역을 갖는 비교적 광대역 신호 통로의 상기 차이에로의 전류라인 베디오 신호분포가 상기 주어진 극성으로서 상기 가산기에서 나타나며, 상기 차이 표현 출려의 적어도 부분들에 대하여 상기 주어진 이득보다 큰 이득을 제공하는 상기형 대역신호통로와, 상기 주어진 극성으로서 상기 가산기에서 상기 차이에로의 전류라인 베디오 선로 분포가 나타나는 방식으로 상기 가산기에 상기 차이 표현출력을 공급하기 위하여 상기 제3빗살형 필터와 상기 가산기 사이에 연결된, 상기 주어진 통과 대역의 저주파수 부분에서만 제한되는 통과 대역을 갖는 비교적 협대역 신호통로와, 재생된 영상의 명도를 제시하기 위하여 상기 가산기의 출력을 잘하는 장치를 포함하는 신호처리장치.11-H type comb filter and between current line video signals and preceding line video signals that provide an output representing the sum of the current line video signal and the preceding line video signals as described herein and shown in the figures. A 21-H type comb filter providing an output representing a difference, a signal adder, and a given connected between the first comb filter and the adder to apply the summed output to the adder having a given polarity. A current line video signal distribution to the difference in the relatively wideband signal path with gain and passband appears in the adder as the given polarity and provides a gain greater than the given gain for at least portions of the difference representation output. The band signal path and transfer from the adder to the difference as the given polarity. A relatively narrow having a pass band limited only in the low frequency portion of the given pass band connected between the third comb-type filter and the adder to supply the difference representation output to the adder in such a way that a flow line video line distribution is shown. And a band signal path and a device for outputting the adder to present brightness of the reproduced image. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
