An apparatus for processing a wide viewing angle image may include: a correction parameter generating unit for analyzing an image input from a camera to generate a correction parameter, a projection geometry generating unit for generating a projection geometry to output a wide viewing angle image by using the correction parameter, and a wide viewing angle image packaging unit for encoding the input image, the correction parameter and the projection geometry to generate a wide viewing angle image package. A method for processing a wide viewing angle image may be performed using the apparatus.
