1. A method for decoding a 360-degree image, the method comprising:
receiving a bitstream in which the 360-degree image is encoded, the bitstream including data of an extended 2-dimensional image, the extended 2-dimensional image including a 2-dimensional image and a predetermined extension region, and the 2-dimensional image being projected from an image with a 3-dimensional projection structure and including at least one face; and
reconstructing the extended 2-dimensional image by decoding the data of an extended 2-dimensional image,
wherein a size of the extension region is determined based on both first width information of the extension region on a left side of the face and second width information of the extension region on a right side of the face, both the first width information and the second width information being obtained from the bitstream,
wherein sample values of the extension region are determined differently according to a padding method selected from a plurality of padding methods,
wherein the extended 2-dimensional image is reconstructed based on a residual image, the residual image being generated by decoding information on the residual image included in the bitstream.
