1. A method of correcting video distortion in a projection system, said method comprising:
- projecting an image onto a viewing screen that is based on a predetermined image;
identifying distortions present in the projected image;
determining a set of corrections that compensate for the identified distortions; and
configuring the projection system based on the set of corrections.

Abstract
Anamorphic lenses within a video projector introduce distortion to the projected image due to the material makeup of the anamorphic lenses. The distortions can be identified and compensations can be determined. The compensations can be digitally applied to input video signals to reduce the distortion in the projected image.
