Abstract: An image encoding/decoding method and apparatus are provided. An image decoding method performed by an image decoding apparatus may comprise obtaining palette information and palette index prediction information of a current block from a bitstream, based on a palette mode applying for the current block, constructing a palette predictor for the current block based on the palette information and constructing a palette table for the current block based on the palette predictor, generating a palette index map for the current block based on the palette index prediction information, and decoding the current block based on the palette table and the palette index map, The palette predictor may be selectively updated based on a split structure of the current block.
