A method for processing information regarding omni-directional images is provided. The method includes generating a first two-dimensional (2D) image projected from a first omni-directional image, generating a second 2D image projected from the second omni-directional image, generating a third 2D image corresponding to a 2D image projected from a third omni-directional image, generating a fourth 2D image projected from a fourth omni-directional image, generating a fifth 2D image corresponding to a 2D image projected from a fifth omni-directional image generating a sixth 2D image corresponding to a 2D image projected from a sixth omni-directional image, and generating a seventh 2D image corresponding to a 2D image projected from a seventh omni-directional image, a weight for the first omni-directional image, a weight for the second omni-directional image, and a weight for the fourth omni-directional image.
