Classification: CPC H | IPC H

Claim 10:
11. An image encoding method, comprising:
generating encoding information for a target block; and
generating a bitstream comprising the encoding information, wherein:
the encoding information indicates whether residual block information for generating a reconstruction block for the target block is present in the bitstream,
in decoding for the target block, the reconstruction block is generated based on a prediction block for the target block,
in decoding for the target block, the reconstruction block is generated based on intra prediction which uses an intra prediction direction for the target block in a case that the encoding information indicates that the residual block information is not present,
the intra prediction direction determines one or more reference pixels used for the intra prediction, and
values for the encoding information to indicate whether the residual block information is present are 0 and 1.
