Abstract RU 2672185 C1

FIELD: computer equipment.

SUBSTANCE: invention relates to computer equipment. Image prediction decoding method includes generating a prediction signal of the target area from the reconstructed signal by using mode information establishing an inter-picture prediction, the reference picture number and the motion vector in the target area, when it is determined that the target area is not extracted from the recovered segment information and the prediction information attached to the neighboring region is not used; and establishing an adjacent region from a plurality of neighboring regions, based on the identification information for generating a prediction signal of the target area from the recovered signal by using mode information establishing an inter-map prediction, the reference picture number and the motion vector in the established neighboring area when it is determined that the prediction information attached to the neighboring area is used.

EFFECT: technical result consists in reducing the prediction error of the target block.
