Abstract RU 2602365 C2

FIELD: information technology.

SUBSTANCE: invention relates to means of encoding and decoding images. Internal prediction module of the present invention, if the coding mode, selected by the coding control module, is internal prediction mode, generates a predicted image (P_i ⁿ) by performing intraframe prediction processing using pixels, adjacent to the segment P_i ⁿ, that is segmented by segmentation module into blocks, or pixels, adjacent to the segment P_i ^n-1 of segment P_i ⁿ upper level.

EFFECT: technical result is higher efficiency of encoding and decoding with increased number of directed prediction modes without increasing computations volumes.
