Abstract: An image encoding method according to the present disclosure may include generating an atlas based on a plurality of viewpoint images; encoding the atlas; and encoding metadata for the atlas. In this case, the metadata may include first information showing whether a viewpoint image is a background image.

Abstract: Disclosed is an encoder which receives first to third input frames included first intra period and outputs a bitstream corresponding to the third input frame. The encoder includes a motion compensation unit that generates a first reference frame corresponding to the first input frame and a second reference frame corresponding to the second input frame, a union operation unit that generates an overlap frame by performing a union operation based on the first reference frame and the second reference frame, and an inter prediction unit that generates an occupancy code by performing an inter prediction operation on the overlap frame and the third input frame. In this case, the bitstream includes the occupancy code.
