Abstract
브라운관 화면의 조정장치에 관한 것으로, 브라운관 화면을 촬영하여 그 영상신호를 출력하는 카메라와, 상기 카메라로부터 영상신호를 입력받아 디지탈 데이타로 변환하는 아날로그/디지탈 변환부와, 상기 아날로그/디지탈 변환부로부터 디지탈 데이타를 입력받아 저장하는 메모리부와, 상기 메모리부로부터 디지탈 데이타를 읽어들여 처리하고 그 처리결과에 따라 화면 조정 제어신호를 출력하는 제어부와, 상기 제어부에서 출력되는 화면 조정 제어신호를 입력받아 상기 브라운관을 조정하는 편향장치와, 상기 편향장치에서 발생하는 수직 편향 동기 신호와 카메라 게이트 신호를 이용하여 각 색신호마다 자동적으로 절환신호를 출력하는 색신호 절환부를 구비하여 편향장치에서 브라운관에 공급되는 수직 편향 동기신호에 동기된 카메라의 시프트 게이트 신호를 이용하여 각 색신호가 자동적으로 절환되게 하여 각 색신호의 영상데이타를 저장하여 처리함으로써, 브라운관의 측정속도가 빨라지고, 정밀하게 측정가능하다.An analog / digital converter for receiving a video signal from the camera and converting the video signal into digital data; and an analog / digital converter for converting the video signal from the analog / A control unit for reading and processing digital data from the memory unit and outputting a screen adjustment control signal according to a result of the processing; and a control unit for receiving a screen adjustment control signal output from the control unit, And a color signal switching unit for automatically outputting a switching signal for each color signal by using a vertical deflection synchronizing signal and a camera gate signal generated by the deflecting apparatus, wherein the vertical deflection synchronizing signal supplied to the cathode- The cipher of the camera synchronized to the signal By processing to save the image data of each color signal in each color signal to be automatically switched by using the gate signal, the faster the speed of the picture tube, can be measured precisely.
