FIELD: information technology.
SUBSTANCE: invention relates to video processing and particularly to fractional interpolation samples used in motion compensation, which reaches low complexity and high accuracy. Said technical result is achieved by fractional sample interpolation is applied to extracted samples to generate fractional samples. Fractional sample interpolation comprises a plurality of filtering operations, where all filtered results from filtering operations are truncated to a predetermined bit depth which does not depend on the bit depth of samples stored in reference image memory.
EFFECT: enabling efficient motion compensation for inter-frame prediction.
