Abstract:
1. A photographing apparatus comprising: an exposure control value calculator for calculating a first exposure control value for a first image obtained by performing non-flash photographing and a second exposure control value for a second image by performing flash photographing based on light received from a subject; a photographing unit for acquiring the first image by performing photographing based on the first exposure control value and for acquiring the second image by performing photographing based on the second exposure control value; an exposure control value difference calculator for calculating an exposure control value difference that is a difference between the first exposure control value and the second exposure control value; a subject brightness calculator for calculating a first subject brightness of the first image and for calculating a second subject brightness of the second image; a subject brightness difference calculator for calculating a subject brightness difference by using the exposure control value difference, the first subject brightness, and the second subject brightness; a reflected flash amount calculator for calculating an amount of reflected flash from the subject brightness difference; and a white balance gain calculator for calculating a white balance gain from the amount of reflected flash.
