1. An image decoding method of performing decoding processing of a picture on a slice basis, the image decoding method comprising:
extracting, from a coded bitstream:
a dependent slice enabling flag indicating whether or not a dependent slice is enabled for the picture, wherein the dependent slice is a slice on which the decoding processing is performed by partially using control information included in a header of a slice different from the dependent slice,
a slice address indicating a starting position of a current slice of the picture, and
a dependency indication indicating whether or not the current slice is the dependent slice;
wherein, when the dependency indication indicates the slice is an independent slice, a context table of arithmetic decoding is initialized,
when the dependency indication indicates the slice is the dependent slice, the context table of arithmetic decoding is not initialized,
the dependent slice enabling flag is disposed in a parameter set common to all slices of the picture,
the slice address is disposed in a slice header of the current slice, and
the dependency indication is disposed in the slice header of the current slice before the slice address and after a syntax element identifying the parameter set.
