An exposure condition when an electronic flash is to be used, i.e., an aperture value and a shutter speed, is determined based on a photometry value. Under the exposure condition, a photographing operation is carried out without use of the electronic flash, and image data obtained by this photographing operation are stored in a first image memory. Further, another photographing operation is carried out with use of the electronic flash, and image data obtained by this photographing operation are stored in a second image memory. The image data stored in the first and second image memories are read out and the luminance signals of corresponding pixels are compared. When the difference between the luminance signals is large, the white balance adjustment is performed based on electronic flash light. When the difference between the luminance signals is small, the white balance adjustment is performed based on the ambient daylight.
