METHOD AND APPARATUS FOR ENCODING/DECODING A VIDEO SIGNAL BASED ON WEIGHTED PREDICTION, AND A RECORDING MEDIUM STORING A BITSTREAM

摘要

An image decoding method and apparatus according to the present disclosure determine an inter prediction mode of a current block, derive motion information of the current block according to the inter prediction mode, obtain a first prediction block of the current block based on the motion information, , by applying at least one of a weight, an offset, and a first variable for explicit weighted prediction to the first prediction block to obtain a second prediction block of the current block.
