Abstract: An image encoding/decoding method and apparatus for signaling picture output information and a recording medium storing a bitstream are provided. An image decoding method may comprise obtaining picture output information indicating whether a picture included in an output layer in a bitstream is output and performing processing in a DPB of the picture based on the picture output information. The picture output information of a first value may indicate output of the picture and the picture output information of a second value may indicate non-output of the picture. The bitstream may be restricted so that the output layer in the bitstream includes at least one picture whose picture output information is the first value.
