FIELD: information technology.
SUBSTANCE: invention relates to encoding/decoding images. Image decoding device comprises: an input means for receiving input of compressed image data; a recovery means for extraction of a residual block signal from compressed image data; a device for decoding the prediction mode for recovery of the encoded prediction mode information for generating a prediction mode; a predicted signal generating means for generating a predicted block signal basing on the said prediction mode; an image recovery means for summation of the predicted signal with a reproducible residual signal to recover a pixel signal of the said block; a storage means for storing the recovered pixel signal.
EFFECT: technical result is increased efficiency of decoding the prediction mode information.
