FIELD: image encoding and decoding technologies.
SUBSTANCE: result is achieved by determining the prediction values for the pixel points of the current image block; determining gradient values for the pixel points of the current image block based on the prediction values for the pixel points of the current image block; determining shift vectors for pixel points of the current image block; determining prediction compensation values for the pixel points of the current image block based on gradient values and shift vectors for the pixel points of the current image block; and determining prediction end values for the pixel points of the current image block based on the prediction values and prediction compensation values for the pixel points of the current image block.
EFFECT: expansion of areas of application of prediction compensation regulation.
