FIELD: image processing means.
SUBSTANCE: invention relates to the area of decoding a predictive-coded image. Image decoding device comprises an input means for receiving compressed image data, comprising a residual signal and coded information on the prediction mode; recovery means for extracting the residual signal of the target block from the compressed image data; device for decoding the prediction mode for recovery of the encoded prediction mode information for generating a prediction mode; means for generating a predicted signal of said target block based on said prediction mode; image recovery means for adding the predicted signal with the reproduced residual signal to recover the pixel signal of the target block; and storage means for storing the recovered pixel signal as a reproduced pixel signal.
EFFECT: increased efficiency of decoding information about the prediction mode of the target block.
