ABSTRACT:
In a digital video coding apparatus, the image compression rate can be improved and the worsening of image quality can be decreased. As well as conducting the motion compensated prediction, the predictive residue at this point is obtained, and in addition to the above, as well as conducting the prediction processing among hierarchical images by using the hierarchical image, the predictive residue at this point is obtained, and the predictive residue according to the motion compensated prediction and the predictive residue according to the hierarchical prediction are adaptively selected and combined and this selected or combined predictive residue is encoded.
