Abstract
An image encoding/decoding method and apparatus are provided. An image decoding method performed by an image decoding apparatus may comprise determining a current block by splitting an image, identifying whether a palette mode is applied for the current block based on a palette mode flag obtained from a bitstream, obtaining palette mode encoding information of the current block from the bitstream based on a tree type of the current block and whether the palette mode is applied for the current block, and obtaining chroma component prediction information of the current block from the bitstream based on the palette mode being not applied for the current block.
