Abstract
A region extracting sectionextracts an image of a subject region and an image of a background region from a picked up image. A region-specific exposure control amount calculating sectioncalculates a subject region exposure control amount based on the image of the subject region and a background region exposure control amount based on the image of the background region. An exposure control amount calculating sectionsets a contribution ratio of the subject region exposure control amount and a contribution ratio of the background region exposure control amount, and calculates an exposure control amount for use in exposure adjustment by mixing the subject region exposure control amount and the background region exposure control amount at a mixing ratio based on the set contribution ratios. A control sectioncontrols a shutter speed, an aperture value, and other settings based on the exposure control amount calculated by the exposure control amount calculating section. Thus, regardless of whether or not flash light emission is to be performed, stable exposure is obtained with natural, balanced brightness ensured in the picked up image.
