Claim 1:
2. A video encoding method, comprising:
generating 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 a intra prediction mode candidate list, for a current block, including a plurality of candidate intra prediction modes excluding a planar mode;
generating 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 plurality of candidate intra prediction modes are determined using an intra prediction mode of a left neighboring block of the current block and an intra prediction mode of an upper neighboring block of the current block.
