. According to an 00th aspect of the present invention, in the image coding method of the 0th aspect, the predetermined shape information includes: in addition to the shape coded data, partition data for distinguishing partitions of stream parts corresponding to areas as units of coding, which partition each predetermined shape frame in the shape coded data; and a decoded shape value which is obtained by decoding the shape coded data. Therefore, the capacity of the memory which contains input shape information can be saved.
