An image decoding method may include: obtaining, from a sequence parameter set of a bitstream, information indicating a plurality of first reference image lists for an image sequence including a current image; obtaining, from a group header of the bitstream, an indicator for a current block group including a current block in the current image; obtaining a second reference image list by modifying a first reference image list indicated by the indicator, from among the plurality of first reference image lists, into the second reference image list; and prediction-decoding a lower block of the current block based on a second reference image included in the second reference image list.
