Projection systems and methods using widely-spaced projectors
Abstract:
A theater utilizes multiple projectors that are widely spaced. The wide spacing of the projectors reduces hot spotting that occurs on flat, curved, retro-reflective, and other types of screens. The projectors are spaced widely apart and generally are placed at opposite sides of the theater. The wide spacing causes a trapezoidal distortion or effect which may be electronically compensated for by, for example, changing pixel locations on modulators of the projectors such that same (or corresponding) pixels modulated in both projectors are ultimately projected onto a same pixel area of the screen. The invention is particularly advantageous in polarization based 3D systems which generally require high directivity screens where hot spotting and related crosstalk are common.
