In a digital camera, when flash shooting is performed, a maximum distance at which a subject can be illuminated to appropriate brightness is calculated based on the guide number of a flash and the open aperture value of an aperture stop, and the distance to the subject measured is compared with the maximum distance. If the distance to the subject is equal to or shorter than the maximum distance, the exposure time is set at a predetermined value, and the amount of the flash light emitted is controlled based on the amount of the light reflected from the subject, and white balance of the taken image is adjusted in accordance with the color characteristics of the flash light. If the distance to the subject is greater than the maximum distance, the exposure time is set to be longer than the predetermined value in order to use a larger amount of ambient light to illuminate the subject, and white balance of the taken image is adjusted in accordance with the color characteristics of the ambient light.
