Abstract

Provided is an image encoding/decoding method and apparatus. The image decoding method comprises obtaining subpicture information from a bitstream, deriving one or more subpictures in a current picture based on the subpicture information, and decoding a current subpicture in the current picture based on the subpicture information. The subpicture information may comprise a first flag specifying whether each of the one or more subpictures is treated as a picture, and, based on the bitstream including at least one first layer referring to a current layer including the current picture, the first flag for the first subpicture included in a first layer and corresponding to the current subpicture, and the first flag for the current subpicture have the same value.
