Abstract

Image Distortions introduced by the optical geometry of typical video projection systems are discussed and analyzed. The major distortions are caused by the fact that the object (e.g. the projection CRT image) and the projection screen are not parallel. Means for correcting the distortions are discussed and examples are given for a typical CRT based projector and for a liquid crystal light valve projector.
