ABSTRACT:
The invention relates to an automatic keystone correction system and method. The system includes an interface to display a pattern on a projection surface and a controller to distort image data responsive to the pattern. The pattern includes a plurality of polygons, each with a predetermined shape. Each polygon corresponds to a particular system rotation angle. The controller distorts the image data responsive to the rotation angle. A user interacts with the interface to identify a particular polygon that, when projected on a projection surface, has a predetermined shape.
