PICTURE CODING METHOD AND PICTURE CODED DATA

摘要

PROBLEM TO BE SOLVED: To provide a picture coding apparatus and picture decoding apparatus for generating coded data by selectively using an inter-pixel filter in accordance with various situations.

SOLUTION: A picture coding apparatus 300 is a picture coding apparatus that codes a difference between picture data Img representing an input picture and predictive picture data Pred representing a predictive picture for the input picture and generates coded picture data, and includes a picture decoding unit 104 for decoding coded picture data Img after the picture data Img are coded; inter-pixel filters A303 and B304 for performing inter-pixel filter operation for decoded picture data Recon obtained by the picture decoding unit 104; switches 301 and 302 for selecting one of the inter-pixel filters; and an inter-picture predicting unit 108 for generating the predictive picture data Pred for the input picture data Img using filtered decoded picture data FilteredImg 1, as reference picture data Ref obtained by the selected inter-pixel filter.
