Title:
符号化歪除去方法
Document Type and Number:
Japanese Patent JP4688973
Kind Code:
B2
Abstract:
Mosaic-shaped block noise occurs when a compressed video signal is reproduced. This block noise is removed, but removing block noise from every block using a deblocking filter imposes a significant load on the deblocking filter. This load is therefore reduced by determining whether coding distortion removal (deblocking) is necessary, and applying a deblocking filter only when needed.
