PREDICTION IMAGE ENCODING APPARATUS, PREDICTION IMAGE ENCODING METHOD, PREDICTION IMAGE ENCODING PROGRAM, PREDICTION IMAGE DECODING APPARATUS, PREDICTION IMAGE DECODING METHOD AND PREDICTION IMAGE DECODING PROGRAM Russian patent published in 2018 - IPC H04N19/105 H04N19/52 H04N19/44 

FIELD: computer engineering.

SUBSTANCE: invention relates to computer engineering. Prediction image decoding apparatus in which the encoded prediction information data is extracted to indicate a prediction method, which should be used in the prediction of the target area signal, and the encoded residual signal data, from the compressed image data obtained by dividing the image into a plurality of areas and encoding the area image data; motion information is restored and stored based on encoded prediction information data; a predicted prediction area signal is generated in the target area based on the restored motion information; reconstructed residual signal of the target area is restored; and a reconstructed pixel signal of the target area is generated based on the predicted signal and the reconstructed residual signal and stored as a previously reconstructed signal.

EFFECT: technical result consists in improvement of efficiency of decoding.
