IMAGE ENCODING APPARATUS, METHOD FOR IMAGE ENCODING, IMAGE DECODING APPARATUS, AND METHOD FOR IMAGE DECODING Russian patent published in 2021 - IPC H04N19/117 H04N19/159 H04N19/176 H04N19/186 H04N19/46 H04N19/86 

FIELD: image processing.

SUBSTANCE: invention relates to the field of encoding and decoding images. In prediction processing, one of the first mode for outputting a predicted pixel in a block using a pixel in an image including the block, the second mode for outputting a predicted pixel in a block using a pixel in an image other than an image including the block, the third mode for generating a predicted pixel in a block using both a pixel in an image including the block and a pixel in an image other than an image including the block, can be used. If the third mode is used in at least one of the first block and the second block, the processing intensity of the blocking elimination filter subject to execution for the boundary between the first block and the second block is set to the same intensity as in the case wherein the first mode is used in at least one of the first block and the second block.

EFFECT: elimination of the blocking effect and suppression of distortion generated at the boundary of the block.
