Abstract:
A white-balance adjusting apparatus for providing an optimal gain to a color information signal corresponding to a subject image thereby adjusting white balance while suppressing a skin color component contained in the color information signal from changing, comprising:a color evaluator for evaluating colors of a predetermined plurality of portions of the subject image based on the color information signal; a luminance evaluator for evaluating luminances of the predetermined plurality of portions based on the color information signal; a remover for removing a plurality of luminance evaluation components given by said luminance evaluator respectively from a plurality of color evaluation components provided by said color evaluator; a table having a first numeral related to a monochromatic color and a second numeral related at least to a skin color; a detector for detecting from the table respective numerals related to the components removed by said remover; and an optimal gain calculator for calculating the optimal gain based on the numerals detected by said detector and the color evaluation components.
