Abstract
A method and apparatus are disclosed for monitoring the location of one or more viewer(s) and dynamically adjusting the image to compensate for the current location of the viewer(s). The image is adjusted to compensate for a viewing location (pan angle, .THETA., tilt angle, .PHI., or distance, d) outside of a specified range of values. The input image is adjusted so that the output image appears as originally intended, for the current viewing location of the viewer. A linear transformation technique is applied to the original image to generate a modified image. The linear transformation maps the pixels in the original image to a new space that distorts the image, such that when the modified image is viewed from an offset viewing location the image appears as if being viewed from a direct viewing location.
