CA 2245842

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.

L'invention porte sur un dispositif numérique de micromiroirs (320) servant à modeler la forme de la lumière projetée sur une scène (582) par réflexion sélective d'une partie de la lumière, de manière à influer sur les contours de la lumière projetée sur la scène. Les variations sont commandées par une image qui peut être traitée (812), les effets ainsi obtenus se répercutant sur les contours de l'image lumineuse projetée.
