VIDEO OR IMAGE ENCODING BASED ON IN-BLOCK CODING Russian patent published in 2023 - IPC H04N19/11 H04N19/70 H04N19/105 H04N19/593 H04N19/132 H04N19/176 

FIELD: images encoding.

SUBSTANCE: invention relates to means for encoding images based on intra-block coding. Image information is obtained, including flag information for intra-block coding (IBC) prediction mode and index information for extracting a block vector. The prediction mode for the current block in the current frame is retrieved as the IBC prediction mode based on the flag information. A list of possible options for the IBC prediction mode is retrieved. The list of possible choices includes the block vector choices. The block vector for the current block is retrieved based on the list of possible options for the IBC prediction mode and the index information. Predictive samples of the current block are generated based on the block vector. Reconstructed samples are formed based on predictive samples. The image information contains information regarding the maximum number of block vector candidates included in the candidate list for the IBC prediction mode and information regarding the maximum number of motion vector candidates included in the candidate list for the inter prediction mode.

EFFECT: improving encoding efficiency.
