摘要
64 regions are set on an image sensed picture of a video camera, where evaluating values rij, bij and yij are obtained by averaging color difference signals R-Y and B-Y and luminance signal Y obtained from an image sensing signal for over 1 field period by each region. When determination is made that the difference in the evaluating values between two continuing regions do not exceed a predetermined value according to the obtained evaluating values, that is, when determination is made that continuing regions have the same color, the weighing amount of the color evaluating values of a corresponding region is reduced in producing gain control signals regarding the color difference signals. As a result, the effect of objects of the same color towards white balance adjustment is reduced.
