Abstract
An image encoding/decoding method and apparatus are provided. The image decoding method comprises obtaining palette prediction information and palette index information of a current block from a bitstream, constructing a palette table for the current block based on the palette prediction information, generating a palette index map for the current block based on the palette index information, and decoding the current block based on the palette table and the palette index map. The palette prediction information may comprise run-value information specifying a first palette entry reused in the palette table among palette entries in the palette predictor for the current block, the run-value information may be obtained from the bitstream only when an index value of the first palette entry is smaller than a first size of the palette predictor, and last run-value information of the palette predictor may have a first value for terminating search of the first palette entry, based on the first palette entry being a last reused palette entry in the palette table.
