1. A method of processing video data, comprising:

  • generating halftone data for a first video frame;

    generating halftone data for a second video frame; and

    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 a human visual system model-based perceptual error of the generated halftone data for the second video frame and a human visual system model-based perceptual error of the halftone data for the second video frame after the copying is done.
