| Title: |
Programmable Light Beam Shape Altering Device Using Separate Programmable Micromirrors for each Primary Color |
| Abstract: |
Three-digital micromirror devices ("DMD") are used to alter the shape of
light that is projected onto a stage. The DMDs each receive a primary
color and selectively reflects some light of that color, 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,
thereby carrying out image processing effects on the shape of the light
that is displayed. One preferred application follow the shape of the
performer and illuminates the performer using a shape that adaptively
follows the performer's image. This results in a shadowless follow spot.
