Abstract
A system and method for processing video data are disclosed. In one aspect, a method includes generating halftone data for a first video frame and generating halftone data for a second video frame. The method further includes, to reduce at least one visual artifact, selectively copying the halftone data for the first video frame into the halftone data for the second video frame, the selective copying being based upon a comparison between a predetermined fixed threshold and the difference in the human visual system model-based perceptual error of the originally generated halftone data for the second video frame and the human visual system model-based perceptual error of the halftone data for the second video frame after the copying is done.
