<p>64 regions are set on an image sensing picture of a video camera, wherein evaluating values rij, bij and yij are obtained by averaging color difference signals R-Y, B-Y and a luminance signal Y obtained from a video signal, respectively, over one field period for each region. When producing a gain control signal for each color difference signal, fuzzy inference is made on the basis of these evaluating values and a weighting amount for each color evaluating value for each region is determined. As a result of the weighting, the contribution degree of a color difference signal in a region not including a light source color temperature axis on a color plane is reduced to achieve good white balance adjustment. <IMAGE></p> |
