Title: Video signal processor
Inventor: OZAWA KENJI
IPC: H04N5/16
Filed: 1991-10-28
Abstract: PURPOSE:To always reproduce an excellent black level by monitoring the fluctuation of an entire processing system concerning the video signal processor for a color television receiver. CONSTITUTION:A superimposing part 10 superimposes a test signal for controlling luminance during the retrace line period of a video signal. A first feedback control loop controls the optimum bias of an amplifier circuit 12. A second feedback control loop detects the test signal for the luminance control from a cathode current and controls the DC reproduction of the video signal. Thus, the fluctuation of a DC value in the entire device is suppressed while including a CRT characteristic, the excellent black level can always be reproduced, and the amplifier circuit can optimumly be operated by using the two feedback control loops. Further, since clamping is executed during a horizontal retrace line period by using a control signal due to the cathode current detected during a vertical retrace line period, current detection control during the horizontal retrace line period can equivalently be executed.
