MOVING IMAGE ENCODING DEVICE, MOVING IMAGE DECODING DEVICE, MOVING IMAGE ENCODING METHOD, AND MOVING IMAGE DECODING METHOD Russian patent published in 2018 - IPC H04N19/593 H04N19/82 H04N19/117 

FIELD: physics.

SUBSTANCE: image decoding device contains an intra-prediction module to, when the encoding mode for the block, which is a module for the prediction process is an intra-coding mode, perform the intraframe prediction process above the mentioned block for the intra-prediction image formation, wherein the mentioned intra-prediction module forms the mentioned intra-prediction image of the mentioned block by calculating the predicted value of samples in accordance with the intra-prediction parameter that specifies the type of the intra-prediction and performs the filtering process for the mentioned intra-prediction image only for specific pixels in the mentioned block under the mentioned intra-prediction parameter.

EFFECT: improving the image quality by reducing prediction errors.
