Abstract
Official abstract text for this publication.
A moving image decoding apparatus and decoding method. The apparatus comprises an entropy decoder, a rectangular region size determiner, and a rectangular region decoder. The rectangular region decoder includes a motion compensator performing motion compensation prediction on a motion compensation region using a motion vector information to obtain a prediction image. Further, there is a transformer performing an inverse quantization and inverse orthogonal transformation process based on the block size indication information.
First claim
Opening claim text (preview).
The invention claimed is: 1. A moving image decoding apparatus for decoding an encoded bit stream, the encoded bit stream being obtained by dividing a moving image into rectangular regions and coding the rectangular regions as units including pixel values, the apparatus comprising: an entropy decoder performing entropy decoding on the encoded bit stream to decode information about a size of the rectangular region for a sequence which is a set of a plurality of continuous frames, c…
