Abstract
A more preferable WB gain is calculated during strobe illuminated photography. When a WB gain for an image captured through strobe illuminated photography is calculated, the degree of contribution of strobe light is first estimated. When the degree of contribution is estimated, the image is first divided into a plurality of blocks, and typical brightness values and typical color values of the respective blocks are determined (S). Subsequently, the highest-brightness block among the blocks analogous to the color of strobe light is identified as a strobe color block (S). When there is a strobe color block, the degree of contribution of strobe light is estimated on the basis of the position of the strobe color block, a difference between the brightness of the strobe color block and the brightnesses of other blocks, and the like (Sto S). Meanwhile, when there is no strobe color block, the degree of contribution is estimated on the basis of the position of the highest-brightness block having the highest typical brightness value among the plurality of blocks (S, S).
