摘要

An image decoding method that decodes bit streams including encoded signals for an image that has been divided into a plurality of tiles as well as divided into a plurality of slices, and encoded, said method including a decoding step in which the encoded signals are decoded. Each of the plurality of slices is either a normal slice having information included in the slice header therefor that is used in a different slice or a dependent slice for which information included in the slice header of a different slice is used for decoding. If a normal slice starts from other than at the beginning of the first tile, a second tile encoded after said first tile does not start from a dependent slice.
