Classification: CPC H | IPC H

Claim 1:
2. The image decoding method of claim 1,
wherein the neighboring blocks include a left neighboring block and a top neighboring block of the current block,
wherein based on an intra prediction mode of the left neighboring block and an intra prediction mode of the top neighboring block being not same, and a mode number of the intra prediction mode of the left neighboring block and a mode number of the intra prediction mode of the top neighboring block being greater than a mode number of the DC intra prediction mode, the intra prediction mode candidate list includes the intra prediction mode of the left neighboring block and the intra prediction mode of the top neighboring block as the intra prediction mode candidates,
wherein remaining intra prediction mode candidates of the intra prediction mode candidate list are derived based on a difference between a larger value and a smaller value among the mode number of the intra prediction mode of the left neighboring block and the mode number of the intra prediction mode of the top neighboring block.
