METHOD AND DEVICE FOR ENCODING/DECODING IMAGE SIGNALS Russian patent published in 2025 - IPC H04N19/122 H04N19/109 H04N19/107 H04N19/119 H04N19/132 H04N19/176 H04N19/503 H04N19/513 

FIELD: image decoding means.

SUBSTANCE: generating a merge candidate list for a first block. One of the merge candidates included in the merge candidate list is selected. Performing motion compensation for the first block based on the motion information of the selected candidate for merging, wherein the candidate for merging between sections included in the list of information on movement between sections, is added to the merge candidate list based on the number of spatial merge candidates and temporary merge candidates included in the merge candidate list. Merge candidates comprise a first merge candidate and a second merge candidate, and a prediction unit for the first block is generated based on the first merge candidate and the second merge candidate. First merge candidate merge_idx index information and second merge candidate merge_2nd_idx index information is obtained by analysing a bitstream, and, when the value of information on indices merge_2nd_idx is equal to value of information on indices merge_idx or greater, the value of the index of the second candidate for merging is obtained by adding 1 to the value of information on indices merge_2nd_idx.

EFFECT: high efficiency of prediction between images.
