IMAGE DECODING METHOD, IMAGE CODING METHOD, IMAGE DECODING APPARATUS, IMAGE CODING APPARATUS, PROGRAM, AND INTEGRATED CIRCUITAn image decoding method which can improve both image quality and coding efficiency is an image decoding method for decoding a coded stream which includes a plurality of processing10 units and a header for the processing units, the coded stream being generated by coding a moving picture, the processing units including at least one processing unit layered to be split into a plurality of smaller processing units, the image decoding method including specifying a hierarchical layer having a processing unit in which a15 parameter necessary for decoding is stored, by parsing hierarchy depth information stored in the header (S101), and decoding the processing unit using the parameter stored in the processing unit located at the specified hierarchical layer (S102). 20 Figure 17A |
