ABSTRACT:
According to particular embodiments, a system comprises one or mores light sources, a Digital Micromirror Device (DMD) system, and a controller. A light source is configured to generate light, and the DMD system comprises DMD regions configured to modulate the light. The controller is configured to repeat the following for a number of iterations: instruct each light source to scroll the light across the DMD system at a current amplitude level; instruct one or more DMD regions to operate as one or more active regions that modulate a first portion of the light to generate an image; and instruct the remaining DMD regions to operate as an amplitude modulation region that receives a second portion of the light, the second portion of the light transitioning from a previous amplitude level to the current amplitude level.
