Abstract
A method, system, and apparatus are described. The method includes calculating, via a white balancer, a candidate illumination chromaticity estimate for a current frame and calculating, via a scene prior monitor, a scene prior chromaticity for the current frame as a weighted sum of a scene prior chromaticity from a previous frame and a candidate illumination chromaticity estimate. The method also includes calculating, via a scene invariant illumination chromaticity controller, a final illumination chromaticity for the current frame as a weighted sum of a scene illumination chromaticity for the current frame and the candidate illumination chromaticity estimate.
