Abstract
A CPU 200 acquires image data of a photographed image, determines a specific subject area containing a specific subject in the photographed image, and calculates a specific subject characteristic value for representing a characteristic of image data corresponding to the determined specific subject area. CPU200 calculates a correction value for color balance correction using the calculated specific subject characteristic value and a preset characteristic target value, and executes the color balance correction on the image data using the calculated correction value.
