Abstract
In each optional area of an object to be photographed, image data obtained when a strobe (10) flashes a light and a CCD (3) is exposed to light from the object is compared with image data obtained when the CCD (3) is exposed to light from the object without flashing a light from the strobe by a data processing section 6. A CPU (12) then determines how much the light of the strobe contributes to photography in the each area which has been compared. After that, the CPU (12) suitably selects either a white balance control value given when the strobe does not flash a light or a predetermined white control value given when the strobe flashes a light and performs final white balance control. Both of the values are determined based on sensor data transmitted from a color measuring sensor (9) or based on an image signal transmitted from the CCD (3).
