Abstract

An image coding method of hierarchically coding a plurality of pictures to generate a bitstream, includes: coding each of the plurality of pictures, which belongs to any one of a plurality of hierarchical layers, with reference to a picture belonging to a hierarchical layer which is same as or lower than a hierarchical layer to which the picture belongs, and without reference to a picture belonging to a hierarchical layer which is higher than the hierarchical layer to which the picture belongs; and generating the bitstream by coding the coded pictures and time information indicating decoding times of the coded pictures. The time information indicates that the decoding times are set at equal intervals for low-layer pictures which are the plurality of pictures other than highest-layer pictures belonging to a highest layer among the plurality of hierarchical layers.
