ENCODER, DECODER, ENCODING METHOD AND DECODING METHOD Russian patent published in 2025 - IPC H04N19/52 H04N19/593 

FIELD: image encoding.

SUBSTANCE: determining whether the size of the current block, which is a unit for which a list of possible variants of vectors is formed, is less than or equal to a threshold value; when the size of the current block is less than or equal to the threshold value, generating a candidate vector list by registering the candidate vector using a history-based motion vector predictor (HMVP) in the candidate vector list from the HMVP table without performing the first clipping process; when the size of the current block exceeds the threshold value, a list of candidate vectors is formed by performing a first process of cutting off and recording the candidate vector of the HMVP vector in the list of candidate vectors from the HMVP table, and the current block is encoded using the list of candidate vectors.

EFFECT: high efficiency of encoding images.
