Abstract
본 발명은 컨버어전스 측정장치에 관한 것으로, 특히 브라운관의 컨버어전스 측정시 화면의 영상 정보를 사람이 인식할 수 있는 레벨 이상의 신호는 사람이 인식할 수 있는 최대 레벨의 신호로 출력함으로써 사람이 인식할 수 없는 신호의 처리 과정이 생략되어 처리시간이 절약되도록 브라운관의 화면으로부터 영상을 촬영하여 그 영상신호를 출력하는 1차원 CCD 카메라와, 상기 1차원 카메라로부터 출력되는 영상신호의 레벨을 기준 전압으로 맞추는 신호 레벨 변위부와, 상기 레벨 변위부에서 출력되는 신호를 증폭하는 차동 증폭기와, 상기 차동 증폭기에서 출력되는 신호를 보정하는 영상신호 보정부와, 제어부로부터 영상 신호를 입력받아 영상 동기 신호를 분리하는 동기신호 분리부로 구성되는 컨버어전스 측정장치이다.The present invention relates to an apparatus for measuring convergence, and in particular, a signal higher than a level at which a human can recognize image information on a screen when measuring the convergence of a CRT is output by a signal at a maximum level that can be recognized by a human. One-dimensional CCD camera that takes an image from the screen of the CRT and outputs the image signal so as to save processing time by eliminating the processing of unrecognized signals, and reference voltage level of the image signal output from the one-dimensional camera. A signal level shifter to adjust the signal output from the level shifter, a differential amplifier to amplify the signal output from the level shifter, a video signal corrector to correct the signal output from the differential amplifier, and receive a video signal from a controller Convergence measuring device is composed of a separate synchronization signal separation unit.
