<p>64 regions are set on an image sensed picture of a video camera, where each 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 sensed signal over 1 field period for each region. When determination is made that luminance evaluating value yij out of these evaluating values exceeds a predetermined value, the color evaluating values of the corresponding region are attenuated by a predetermined amount, in producing gain control signals regarding color difference signals. As a result, the effect of an object of high luminance towards white balance adjustment is reduced.</p> |
