Abstract
A method for determining an illuminant in a scene includes, applying, to sampled outputs of a sensor array used to capture the scene, a plurality of color-correction profiles, wherein each color-correction profile corresponds to a particular illuminant, thereby forming a plurality of color-corrected sampled outputs. The method further includes identifying the illuminant in the scene as corresponding to the color-corrected sampled output having the least color variance.
