METHOD AND APPARATUS FOR ENCODING/DECODING AN IMAGE AND RECORD MEDIUM STORING A BITSTREAM Russian patent published in 2022 - IPC H04N19/513 H04N19/56 H04N19/593 

FIELD: encoding.

SUBSTANCE: group of inventions relates to the technology for encoding/decoding images utilising a list of motion information storing previously retrieved motion information. Proposed is a method for generating a list of motion information candidates, generated when decoding an image. The method includes a stage of generating a list of candidates, including motion information generated using the information of a neighbouring block adjacent to the current block. The motion information of the current block is then output using the list of candidates. A prediction block of the current block is generated using the output second motion information of the current block. The list of motion information is also updated in order to store the output motion information of the current block. The list of candidates therein includes at least one of the motion information included in the list of motion information used for the block decoded prior to decoding for the current block.

EFFECT: increase in the efficiency of image compression utilising a list of motion information.
