1. A method of image background adjustment, the method comprising: receiving luminance-chrominance pixel values, a whitepoint value, and a blackpoint value which correspond to an image; identifying white pixels having luminance values within a white offset value of the whitepoint value and having chrominance values within a non-zero white chrominance threshold value of a chrominance neutral point; identifying black pixels having luminance values within a black offset value of the blackpoint value and having chrominance values within a non-zero black chrominance threshold value of the chrominance neutral point; and adjusting pixels by selectively reducing the chrominance values of the identified white and black pixels based at least partially on proximity to the chrominance neutral point and chrominance of at least one neighboring pixel.
