FIELD: video encoding.
SUBSTANCE: line of reference readings of the current block is defined. It is determined whether there is a candidate internal prediction mode that is the same as the internal prediction mode of the current block. The internal prediction mode of the current block is obtained based on the determination. Internal prediction is performed on the current block based on the reference sample line and the internal prediction mode. At least one of the candidate internal prediction modes is obtained by adding or subtracting an offset to the maximum value from the top neighbour block internal prediction mode of the current block and the left neighbour internal prediction mode of the current block. At least one of the candidate internal prediction modes is obtained by adding 2 to or subtracting from the maximum value when the difference between the intra prediction mode of the top neighbouring block and the intra prediction mode of the left neighbouring block is 64.
EFFECT: increased efficiency of video encoding.
