Abstract

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 A114a, a filter B114b, a filter C114c, and a filter D114d; 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.
