1. A video decoding method, comprising:
extracting, from a bitstream, reference sample information indicating reference samples among a plurality of adjacent samples including first adjacent samples and second adjacent samples;
when the reference sample information does not indicate the first adjacent samples, determining an intra prediction mode candidate list, for a current block, including a plurality of candidate intra prediction modes excluding a planar mode;
obtaining, from the bitstream, an index indicating an intra prediction mode for the current block among the plurality of candidate intra prediction modes; and
generating predicted samples of the current block using the intra prediction mode for the current block and the second adjacent samples,
wherein:
the first adjacent samples include an adjacent sample directly adjacent to the current block,
the second adjacent samples include an adjacent sample being above the adjacent sample directly adjacent to the current block,
the adjacent sample being above the adjacent sample directly adjacent to the current block is one line away from the current block, and
the current block is one among a plurality of blocks split from an upper block.
