Patent ID: 7532255

Claim:
A method of improving color transients of an image having a plurality of pixels, the method comprising: defining a color transient detection window around a current pixel; calculating one or more transient characterization values for the color transient detection window with a transient characterization unit, wherein the transient characterization values correspond to a likelihood of a color transition occurring in the color transient detection window; and generating an improved U chrominance value and an improved V chrominance value for the current pixel; wherein the calculating one or more transient characterization values for the color transient detection window further comprises: calculating an average U chrominance value for each column of the color transient detection window to form a plurality of average U chrominance values; calculating an average V chrominance value for each column of the color transient detection window to form a plurality of average V chrominance values; calculating a first U transient characterization value corresponding to a degree that the plurality of average U chrominance values is monotonically increasing; and calculating a first V transient characterization value corresponding to a degree that the plurality of average V chrominance values is monotonically increasing.
