Abstract
A white balance control circuit calculates a first white balance correction value based on image data captured at light-emission timing of a flash unit and calculate a second white balance correction value based on image data captured at non-emission timing of the flash unit. The white balance control circuit acquires an image capturing condition corresponding to the image data captured at the light-emission timing of the flash unit or scene information obtained from color information of the image data captured at the light-emission timing of the flash unit. The white balance control circuit corrects at least one of the first white balance correction value and the second white balance correction value based on the image capturing condition or the scene information.
