ABSTRACT:
An automatic white-balance controlling is for controlling the white-balance of an imaged screen, by controlling the color signal level in accordance with an up-down counting result in a microcomputer. A limited area is established within a VB-VR plane, and a level adjusting operation of the color signals corresponding to the area is limited so as to render a stable white-balance adjusted operation. Judged from data in a time series, the accuracy of the white-balance controlling operation can be assured executing somewhat redundant processing.
