Abstract
A method for calculating and adjusting the color temperature of an image includes calculating an average color temperature and adjusting the chromaticity of each pixel of the image according to the average color temperature. The adjustment may be linear across all pixels or scaled according to the chromaticity of each pixel. The adjustment will not cause pixels to cross chromaticity axis boundaries, thus preserving original colors.
