摘要

FIELD: computer equipment.;SUBSTANCE: device for decoding images with prediction comprises electric circuit, made with possibility of: outputting mode information by processing a function, including adding or subtracting an integer from mode information relating to an intra-frame prediction method corresponding to one of a plurality of adjacent regions; selecting a prediction method for the target area for generating an intra prediction signal based on the derived mode information and the identification mode information; generate intra prediction signal based on selected prediction method; extracting a difference signal for restoring the newly generated difference signal; and recover the target area pixels signal by combining the intra-frame prediction signal and the reconstructed reformed difference signal.;EFFECT: technical result consists in improvement of efficiency of decoding.;5 cl, 14 dwg
