Abstract
The present invention discloses systems, equipment and methods that allow the improved tiling of multiple projections displays in order to create higher resolution images. Equipment and methods are disclosed for improved blending of the seam by optical means where edge blending masks are employed to create a brightness ramp in the blending region. Equipment and methods are also disclosed for the correction of artifacts in an optically blended seam by modifying the brightness of image pixels in the overlap or blend region. Equipment, systems, and techniques are disclosed for preserving the resolution and uniformity of the image across each seam by actively controlling the position of each display using a servo controlled lens mount for the positioning of each projected image in conjunction with a real time image analysis system.
