Abstract
Methods and apparatus for capturing and displaying stereoscopic images are described in a manner that allows a user to obtain a 3d virtual reality experience simulating that of being in a seat at a football game or other event. Rear images are modified, e.g., in luminance intensity, to make them consistent with the luminance intensity of the forward images to avoid or reduce edges or differences in luminance intensity as a users turns his head from viewing a main image area to a side or rear image area. A seamless 3D presentation is made possible through the use of fisheye lenses at capture time and combining of images corresponding to forward and rear image areas as a user turns his or her head requiring a change in the captured image area which is displayed to the user.
