1. An image decoding method comprising:
determining a prediction mode of a current block to perform prediction for the current block based on a bitstream; and
performing decoding for the current block based on the prediction mode of the current block,
wherein the prediction uses a palette mode,
wherein a plurality of sample information groups are used for the current block, and
wherein the plurality of sample information groups are determined based on a scan method for the current block.
