Claim 13:
14. A non-transitory computer-readable recording medium storing a bitstream, the bitstream comprising:
predetermined information indicating whether residual block information for a target block in an image is encoded in the bitstream or not, wherein:
whether the residual block information is present is determined based on the predetermined information,
the target block is generated based on an intra prediction value and the residual block information in response to the predetermined information indicating that the residual block information is present,
the target block is generated based on intra prediction using intra prediction direction information decoded from the bitstream in response to the predetermined information indicating that the residual block information is absent, and
the intra prediction value is generated based on a reference pixel value,
the reference pixel value is determined based on a position of the target block, and
0 and 1 are values for the predetermined information to indicate whether the residual block information is encoded in the bitstream or not.
