摘要

FIELD: computer equipment.;SUBSTANCE: invention relates to the computer equipment. Device for decoding images with prediction comprises electric circuit, made with possibility of: outputting mode information by processing a function, which includes adding ±n to the identification information, which contains a numerical value related to the intra-frame prediction method; determining a first prediction method for the target area for generating an intra prediction signal based on the derived mode information; extracting a relative prediction method; outputting a second prediction method for the target area based on the first prediction method and the relative prediction method; generate intra prediction signal based on derived second prediction method; extracting a difference signal related to the target area from the compressed image data; and recover pixel signal of target area.;EFFECT: high decoding efficiency.;2 cl, 14 dwg
