ABSTRACT:
A white balance control apparatus includes an evaluation value calculation circuit calculating and outputting evaluation values of color components of each of a plurality of regions of digital image data, a luminance conversion part converting the evaluation values of each of the regions into a luminance value, and a high-luminance weighting part converting the evaluation values of each of the regions into a base white balance control amount, calculating a non-weighted white balance control amount from the base white balance control amount and a weighted white balance control amount by performing weighting processing on the base white balance control amount by using the luminance value of each of the regions so that a region of higher luminance has a greater weight, and calculating a white balance control amount to be applied to the image data at a time of image recording by using the weighted and non-weighted white balance control amounts.
