Abstract

A digital micromirror device ("DMD") (320) is used to alter the shape of light that is projected onto a stage (582). The DMD
selectively reflects some light, thereby shaping the light that is projected onto the stage. The control for the alteration is controlled by an image. That image can be processed (812), thereby carrying out image processing effects on the shape of the light that is displayed.
