VIDEO OR IMAGE ENCODING BASED ON IN-BLOCK CODING Russian patent published in 2022 - 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. The prediction mode for the current block in the current frame is retrieved as the prediction mode based on intra-block coding (IBC). The candidate list for the IBC prediction mode is retrieved, wherein the candidate list includes the block vector candidates for the reference block in the current frame. The index information is generated for the block vector of the current block based on the list of possible options for the IBC prediction mode. Image information including index information is encoded. The image information contains information on the maximum number of block vector candidates included in the candidate list for the IBC prediction mode and information on the maximum number of motion vector candidates included in the candidate list for the inter prediction mode.

EFFECT: improving coding efficiency.
