A seamlessly tiled projection system is composed of multiple projectors, a front or rear projection screen, feedback elements, and tiled image processors. Its seamlessness is achieved through the optical and electronic calibrations. The optical calibration in the components of projectors improves the contrast ratio, brightness, and the overall image quality. The electronic calibration aligns the tiled images, and blends the color between adjacent tiles using a camera feedback system. A front projection system with a 2 X 2 array of SXGA (1280 X 1024) projectors is set up to describe the fundamentals of achieving a scalable, high- resolution, seamlessly tiled projection display.
