BRIGHTNESS BASED CHROMATICITY WEIGHTING FOR IMPROVED ILLUMINANT COLOR ESTIMATION FOR AUTO WHITE BALANCING

Abstract: apparatuses, systems, and techniques for white balancing an image are presented. in at least one embodiment, a chromaticity-based weighting function is determined based at least on an estimated scene brightness of the image and applied to exclude or minimize the impact of large colored portions or objects within an image when estimating an illuminant color.
