Abstract

휘도신호와 크로마신호의 동기를 위한 휘도신호지연장치는, 크로마신호의 색부반송파가 갖는 주기보다 작은 주기를 갖는 복수개의 샘플링펄스들을 순차적으로 발생하는 샘플링펄스발생기, 샘플링펄스발생기에 의해 발생된 복수개의 샘플링펄스들 각각에 따라 결정되는 지연시간들만큼 수신된 휘도신호를 지연시키며, 지연된 복수개의 휘도신호들을 출력하는 지연수단 및 외부로부터의 선택제어신호에 응답하여, 지연수단으로부터 출력되는 복수개의 지연된 휘도신호들중의 하나를 선택하여 출력하는 선택출력수단을 포함하므로써, 크로마신호와 동기될 수 있는 복수개의 지연시간들로 지연된 휘도신호를 발생하므로써, 크로마신호와 휘도신호의 동기에 의한 화상의 해상도 향상의 효과를 제공한다.The luminance signal delay device for synchronizing the luminance signal with the chroma signal includes a sampling pulse generator for sequentially generating a plurality of sampling pulses having a period smaller than that of the color carrier of the chroma signal, and a plurality of sampling pulse generators. A delay means for delaying the received luminance signal by delay times determined according to each of the sampling pulses, the delay means for outputting the plurality of delayed luminance signals and a plurality of delayed luminance output from the delay means in response to a selection control signal from the outside; Improving image resolution by synchronizing the chroma signal with the luminance signal by generating the luminance signal delayed with a plurality of delay times that can be synchronized with the chroma signal by including a selection output means for selecting and outputting one of the signals. To provide the effect.
