APPARATUS FOR REDUCING QUANTIZATION ARTIFACTS IN AN INTERFRAME HYBRID CODING SYSTEM WITH MOTION COMPENSATION

摘要

Apparatus for reducing halos at moving edges adjacent flat areas in successive images produced by a system using differential pulse code modulation with motion compensation in which the output of a DCT is quantized by reducing the size of the quantization steps in those areas of the image which are indicated as containing such moving edges adjacent flat areas. <IMAGE>
