Abstract: When a flash device is to be controlled in synchronism with continuous image photography, this flash device is controlled so that the interval of continuous image photography is shortened, and that a correct exposure state is obtained even if continuous photography is performed under conditions by which the exposure state changes momentarily, such as when a moving object is to be photographed. To this end, in a continuous photographing mode in which a plurality of images are continuously captured at predetermined intervals (S101), the light emission amount of the flash device is determined from the reflected light amount of light emitted beforehand when the first image is to be captured (S102-S105, S107). When the nth (n>1) image is to be captured, the light emission amount is determined by using the reflected light amount of the flash device which emits light when the (n?1)th image is captured (S106).
