Abstract
A first line passing through a coordinate point which represents the light-source color of ambient light is drawn so as to cross a line segment connecting two coordinate points which points respectively represent colors of light emitted from the two light-emitting sources. An image of a subject is captured while light is emitted from the two light-emitting sources toward the subject in such a manner that the volumes of light emitted from the two light-emitting sources respectively correspond to those represented by a predetermined point which is, or close to, the intersection point of the first line and the line segment on the basis of the intersection point and light volume information. A White Balance adjustment correction value is obtained on the basis of light volume information with respect to the two light-emitting sources, the predetermined point, and the point representing the light-source color.
