Abstract:
1. An image decoding method, including reproducing data on a reproducible pixel block within each frame during a period when it is not possible to refer to a frame that serves as a reference for inter-frame coding, in a process of decoding a coded data sequence coded by performing at least one of an intra-frame coding processing and an inter-frame coding processing on image signals, wherein the frame that serves as a reference for inter-frame coding is an intra frame and the frame that does not serve as a reference for inter-frame coding is a non-intra frame, and wherein when decoding starts from a non-intra frame, said period when it is not possible to refer to a frame that serves as a reference for inter-frame coding includes from the non-intra frame to a first intra frame following the non-intra frame.
