Claim Text:
1. An image coding method for coding tiles and slices into which an image is partitioned, to generate a bitstream, the method comprising: partitioning the image into the tiles and the slices; embedding, into the bitstream, a restriction indicator indicating that partitioning of a picture is restricted; and coding the tiles and slices resulting from the partitioning and based on the restriction indicator, wherein each of the slices is either a normal slice having, in a header, information used for an other slice or a dependent slice which is decoded using information included in a slice header of another slice, and in the partitioning, when the normal slice starts from a position other than a beginning of a first tile, the image is partitioned into the tiles and the slices to prevent a second tile coded next to the first tile from starting from the dependent slice.
