Abstract
An image encoding/decoding method and device, according to the present disclosure, may: generate a basic prediction block of a current block by performing bi-prediction on the basis of a first inter prediction mode; derive an additional reference block of the current block on the basis of a second inter prediction mode; and generate a final prediction block of the current block by weighted summing the basic prediction block and the additional reference block.
