Abstract

We have developed a new method for correcting geometrical distortion of three-lens CRT video projector. By applying this method, we can reduce geometrical distortion to less than 0.3% of the raster height. This system consists of a CCD Camera taking a part of screen, a Mirror controlled by two Stepping Motors, a Frame Memory, a CPU (ex. a personal computer), and 3-D coordinates transfer technique.
