ABSTRACT:
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) is coded; inter pixel filters A and B (303and304) for performing inter pixel filter operation for decoded picture data (Recon) obtained by the picture decoding unit (104); switches (301and302) 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 (FilteredImg1), as reference picture data (Ref), obtained by the selected inter pixel filter.
