Abstract
The present invention allows for selecting a predetermined chromatic color for extraction from among a plurality of chromatic colors based on the result of identification of acquired photographing information. When the value of a white extraction area of the photographing information is smaller than a first threshold value, it is determined whether the value of the area of the selected predetermined chromatic color is greater than or equal to a second threshold value. If the value of the predetermined chromatic-color area is determined to be greater than or equal to the second threshold value, white balance is controlled by bringing the value of the predetermined chromatic-color area near to a predetermined target color value.
