Abstract: An image coding method according to an aspect of the present invention includes: dividing a picture into tiles (S201); coding the tiles to generate pieces of coded data each of which corresponds to a different one of the tiles (S202); and generating a bitstream including the pieces of coded data (S203). The coding of the tiles (S202) includes: generating a first code string by coding a first tile which is one of the tiles, without referring to coding information used in coding another one of the tiles (S211); and adding a bit string after the first code string to make a bit length of first coded data which is one of the pieces of coded data, a multiple of a predetermined N bits, N being an integer greater than or equal to 2 (S213).

Abstract: An image encoding method for encoding a multiview video is provided. The method includes: determining a maximum number of per-picture pixels (127) and a maximum buffer size (128) which corresponds to a maximum number of candidate reference images for use in a non-multiview coding, based on a level signal (126) representing a coding level with reference to a table (T1) (S101); calculating a maximum number of candidate reference views (129) for use in inter-view predictive coding using the maximum number of per-picture pixels (127), an image size of an input image (125), and a scale factor for use in multiview video coding (S102); and calculating an MVC maximum buffer size (130) corresponding to a maximum number of candidate reference images for use in multiview video coding, using the maximum number of views (129), and the maximum buffer size (128) (S103).

Abstract: An image encoding method according to an aspect of the present invention includes: generating, from a plurality of first sub-bitstreams which are obtained by encoding a plurality of images on a per layer basis according to spatial scalable image encoding, a second sub-bitstream including two or more first sub-bitstreams corresponding to two or more layers, the two or more first sub-bitstreams being included in the plurality of first sub-bitstreams; and generating a descriptor including a first field indicating a minimum value for two or more layer identifiers indicating the two or more layers and a second field indicating a maximum value for the two or more layer identifiers.
