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

摘要

A moving picture coding apparatus includes (i) an inter-pixel filter (114) having the following filters for filtering decoded image data so as to remove block distortion which is high frequency noise around block boundaries: a filter A114a, a filter B114b, a filter C114c, a filter D114d, each having a different filtering strength, and (ii) a filter processing control unit (110) for determining a filtering strength of the inter-pixel filter (114).
