FIELD: computer equipment.
SUBSTANCE: video decoding method executed by the decoding device comprises deriving the intra-prediction mode of the current block; bringing adjacent samples, including left adjacent samples and upper neighboring samples of current block; deriving reference samples for prediction of the target sample of the current block from neighboring samples based on the position of the target sample and the prediction angle of the intra-prediction mode; determining an interpolation filter for the target sample based on the intra-prediction mode and the size of the current block and outputting the prediction selection of the target sample based on the interpolation filter and the reference samples, wherein determination of the interpolation filter for the target sample based on the intra prediction mode and the size of the current block comprises determining whether the size of the current block is less than the first specific value.
EFFECT: technical result consists in improved efficiency of coding.
