Abstract
An image encoding/decoding method and apparatus are provided. An image decoding method according to the present disclosure is performed by an image decoding apparatus. The image decoding method comprises deriving a prediction mode of a current block, constructing a merge candidate list for the current block, based on the prediction mode of the current block being a triangle partition mode (TPM), deriving motion information of two partitions of the current block based on the merge candidate list and two merge indices of the current block signaled through a bitstream, generating a prediction block of the current block based on the motion information, storing motion information of the current block, and updating a history-based motion vector predictor (HMVP) buffer based on the motion information of the current block.
