Claim 5:
6. A non-transitory computer-readable storage medium storing a bitstream, the bitstream comprising:
intra prediction mode information for a target block;
wherein:
an intra prediction mode of the target block is derived using the intra prediction mode information,
a prediction block for the target block is generated by performing intra prediction for the target block that uses the intra prediction mode,
the intra prediction for the target block is performed using a reference sample line selected from a plurality of reference sample lines,
filtering for reference samples in the selected reference sample line is performed in a case that the selected reference sample line is adjacent to the target block, and
the filtering for reference samples in the selected reference sample line is not performed in a case that the selected reference sample line is not adjacent to the target block.
