Filtering intensity decision method, moving picture encoding method, and moving picture decoding method

摘要

A moving picture coding apparatus including an inter-pixel filter having the filters for filtering decoded image data so as to remove block distortion which is high frequency noise around block boundaries. The filters include a filter A 114 a, a filter B 114 b, a filter C 114 c, and a filter D 114 d; each having a different filtering strength. The coding apparatus also includes a filter processing control unit for determining a filtering strength of the inter-pixel filter.
