Abstract

본 발명은 텔레비젼의 수평동기신호 보정장치로서 인가되는 복합영상신호로부터 소정의 수평동기신호를 검파하고 이 수평동기 신호의 전압 레벨을 근거로 수평동기신호의 증폭비를 결정하여 정상적인 동기신호를 출력할 수 있도록 한 것으로, 복합영상신호로부터 수평동기신호를 검파 출력하는 동기신호 분리부(10)와, 상기 동기신호 분리부(10)로부터 인가되는 수평동기신호의 전압레벨을 근거로 소정의 직류 제어전압을 발생시키는 제어전압 발생부(20)와, 상기 제어전압 발생부(20)로부터 입력되는 소정의 직류 제어전압에 따라 동기신호 분리부(10)로 부터 인가되는 수평동기신호를 증폭하도록 한 동기신호 증폭부(30)로 구성되는 비표준 동기신호 자동보정장치를 제고하여, 영상신호의 수평동기 레벨에 따라 분리되는 동기신호의 전압 레벨이 자동으로 보정될 수 있도록 한 발명이다.The present invention detects a predetermined horizontal synchronizing signal from a composite video signal applied as a horizontal synchronizing signal correction apparatus of a television, and determines an amplification ratio of the horizontal synchronizing signal based on the voltage level of the horizontal synchronizing signal to output a normal synchronizing signal. The DC control voltage is determined based on the voltage level of the synchronization signal separating unit 10 for detecting and outputting the horizontal synchronization signal from the composite video signal and the horizontal synchronization signal applied from the synchronization signal separating unit 10. And a synchronization signal for amplifying the horizontal synchronization signal applied from the synchronization signal separation unit 10 according to the control voltage generator 20 for generating a control signal and the predetermined DC control voltage input from the control voltage generator 20. By improving the non-standard synchronization signal automatic correction device composed of the amplification unit 30, the voltage level of the synchronization signal separated according to the horizontal synchronization level of the video signal automatically It is an invention that can be corrected to.
