IMAGE ENCODING DEVICE, IMAGE DECODING DEVICE, IMAGE ENCODING METHOD AND IMAGE DECODING METHOD Russian patent published in 2017 - IPC H04N19/50 H04N19/159 

FIELD: physics.

SUBSTANCE: internal prediction module of the present invention, if the encoding mode determined by the encoding control module, is a mode of internal prediction, generates the predicted image (P_iⁿ) by performing the processing of intra-frame prediction by using pixels adjacent to the segment P_iⁿ, which is segmented by segmentation module on blocks or pixels adjacent to a segment P_i^n-1 of the upper P_iⁿ segment level P_iⁿ.

EFFECT: increasing the efficiency of encoding and decoding with increasing the number of the directional prediction modes without increasing the volume of calculations.
