FIELD: computer engineering.
SUBSTANCE: invention relates to computer engineering. Image decoding method, in which data is removed from the bit stream which indicates the intra-frame prediction mode applied to the current block, which must be decoded; determining one of neighbouring pixels adjacent to the current unit, and filtered adjacent pixels, filtered from the said adjacent pixels as reference pixels based on at least one of the size of the current block and intra-frame prediction mode of the current block; performing intraframe prediction with respect to current block using the extracted information and said defined reference pixels, when the size of the current unit is N × N, where N is an integer, said adjacent pixels include 2N neighbouring pixels adjacent to upper side and top right side of the current block, and 2N neighbouring pixels adjacent to the left side and bottom left side of the current unit, picture is split into a variety of maximum coding units according to data on maximum size of the coding unit.
EFFECT: technical result consists in improvement of efficiency of decoding.
