SYSTEM AND METHOD FOR IMPROVING THE QUALITY OF HALFTONE VIDEO USING A FIXED THRESHOLD
First Claim
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.

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.

13. An apparatus for processing video data, comprising:
-
a memory device having stored therein at least halftone data for a first and second video frame; a processor that is configured to communicate with said memory device and is configured to reduce at least one visual artifact by selectively copying the halftone data for the first video frame into the halftone data for the second video frame with 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 generated halftone data for the second video frame and the human visual system model-based perceptual error of this halftone data after the copying has been done.

14. An apparatus for processing video data, comprising:
-
means for generating halftone data for a first video frame; means for generating halftone data for a second video frame; and means for reducing at least one visual artifact by 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 after the copying is done.
