MOVING IMAGES ENCODING DEVICE, MOVING IMAGE DECODING DEVICE, MOVING IMAGES ENCODING METHOD AND MOVING IMAGES DECODING METHOD Russian patent published in 2019 - IPC H04N19/593 H04N19/82 H04N19/117 

FIELD: computer equipment.

SUBSTANCE: image decoding device comprises an intra-prediction module for, when a coding mode for a block, which is a module for the prediction process, is an intra-encoding mode, performing an intra-frame prediction process on said block to generate an intra-prediction image, wherein said intra-prediction module generates said intra-prediction image of said block by calculating a predicted value from reference samples according to an intra-prediction parameter indicating an intra prediction type, and performs filtering process for said intra-prediction image only for specific pixels in said block according to colour component type and unit size of said block.

EFFECT: technical result is improving image quality by reducing prediction errors.
