IMAGE CODING DEVICE, IMAGE DECODING DEVICE, IMAGE CODING METHOD AND IMAGE DECODING METHOD Russian patent published in 2015 - IPC H04N19/50 

Abstract RU 2547617 C2

FIELD: electricity.

SUBSTANCE: subject of the present invention is the internal forecast module; if the coding mode, selected by the coding control unit, is an internal forecast mode, the forecasted image (Pin) is formed by means of processing of intra-frame forecast using pixels, contiguous with the segment Pin, which is segmented by means of the module of segmentation into blocks, or pixels, contiguous with the segment Pin-1 of the upper level of the segment Pin.

EFFECT: improvement of efficiency of coding and decoding.
