Method and apparatus for processing omni-directional image

A device for processing information regarding an omni-directional image, the device comprising:

• a communication interface;
• and
• a processor connected with the communication interface,
• wherein the processor is configured to:
• generate a first two-dimensional (2D) image projected from a first omni-directional image based on a position crossing a straight line passing through a first position which is a center of the first omni-directional image and a second position which is a center of a second omni-directional image,
• generate a second 2D image projected from the second omni-directional image based on the position crossing the straight line passing through the first position and the second position,
• generate a third 2D image corresponding to a 2D image projected from a third omni-directional image having a center in a third position between the first position and the second position,
• generate a fourth 2D image projected from a fourth omni-directional image based on a position crossing a straight line passing through the center of the second omni-directional image and a center of the fourth omni-directional image,
• generate a fifth 2D image corresponding to a 2D image projected from a fifth omni-directional image having a center in a fifth position between the second position and the fourth position based on the second 2D image and the fourth 2D image,
• generate a sixth 2D image corresponding to a 2D image projected from a sixth omni-directional image having a center in a sixth position between the first position and the fourth position based on the first 2D image and the fourth 2D image, and
• generate a seventh 2D image corresponding to a 2D image projected from a seventh omni-directional image having a center in a seventh position between the first position, the second position, and the fourth position based on the third 2D image, the fifth 2D image, the sixth 2D 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.
