Abstract

비디오 신호입력단(VI)의 합성 영상신호로부터 입력신호의 동기 및 버스트 신호의 상태를 검출하고, 상기 동기 및 버스트 검출신호와 동기하여 칼라(CBS) 및 제어신호(CS)를 발생한다.The state of the synchronization signal and the burst signal of the input signal is detected from the composite video signal of the video signal input terminal VI, and the color CBS and the control signal CS are generated in synchronization with the synchronization and burst detection signal.

상기 동기 및 버스트 검출처리과정을 통과한 영상신호로부터 상기 칼라바 신호를 삽입하는 시점에서 원래신호를 제거하고 상기 원래신호와 상기 칼라바 신호 발생 칼라바(CBS) 신호를 합성하여 증폭한 후 CRT에 칼라 조정용 칼라바 신호가 표시된다.When the color bar signal is inserted from the image signal passing through the synchronization and burst detection process, the original signal is removed, and the original signal and the color bar signal generating color bar (CBS) signal are synthesized and amplified to the CRT. The color bar signal for color adjustment is displayed.
