Abstract: An adaptive fill-flash technique for digital photography that employs flash and no-flash image pairs. A flash image, captured using a flash of known characteristics and ambient light, and an ambient light image, which is taken with only ambient light, of the same image subject matter are acquired. A flash only image, computed by subtracting the known ambient light image from the flash and ambient light image, is computed. The flash only image and the ambient light image are then each white balanced to the flash light and the ambient light, respectively, to form two white-balanced images. These two white-balanced images are then added to form a white balanced image, I, in which the flash and ambient light color agree. It is also possible to reduce the hot spots in image I, and adjust flash strength.
