Claim 5:
6. An image encoding method, comprising:
generating encoding information indicating whether residual block information is used in generating a reconstruction block for a target block; and
generating the reconstruction block for the target block, wherein:
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 using an intra prediction direction for the target block in a case that the encoding information indicates that the residual block information is not used,
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.
