<P>PROBLEM TO BE SOLVED: To provide a method and an apparatus for processing video images for dynamic false contour effect compensation. <P>SOLUTION: The method comprises the steps of: dividing each of the video images into at least a first type of region and a second type of region according to the video gradient of the image, a specific video gradient range associated with each type of region; allocating a first set of sub-field code words to the first type of region and a second set of sub-field code words to the second type of region, the second set being a subset of the first set; encoding the pixels of the first type of region with the first set of sub-field code words and encoding the pixels of the second type of region with the second set of sub-field code words, wherein for at least one horizontal line of pixels, the region of second type is extended, until the next pixel in the first type region is a pixel encoded by a sub-field code word belonging to both first and second set of sub-field code words. <P>COPYRIGHT: (C)2008,JPO&INPIT |
