A method and apparatus are provided for processing information about an omni-directional image. The method includes generating a first two-dimensional (2D) image projected from a first omni-directional image, by setting points on the first omni-directional image, which intersect a straight line passing through a first position that is a center of the first omni-directional image and a second position that is a center of a second omni-directional image, to a first pole and a second pole, generating a second 2D image projected from the second omni-directional image, by setting points on the second omni-directional image, which intersect the straight line passing through the first position and the second position, to a third pole and a fourth pole, and generating a third 2D image corresponding to a 2D image projected from a third omni-directional image centered in a third position between the first position and the second position, based on the first 2D image and the second 2D image.
