OPERATING METHOD OF IMAGE CODEC CIRCUIT, ENCODING METHOD FOR ENCODING IMAGE DATA AND DECODING METHOD FOR DECODING IMAGE DATA

摘要

The present invention relates to a method for encoding image data including multiple image blocks. The method includes the steps of: selecting a window which has one image block as a main image block among multiple image blocks; and performing multiple loop filtering schemes for image data of the selected window. The loop filtering schemes comprises deblocking filtering, sample adaptive offset filtering, and adaptive loop filtering. The selected window is not consistent with the one image block.
