Claim:
1. A scanning projector system, comprising: a first light emitting element that selectively emits light of a first color; a second light emitting element that selectively emits light of a second color; a third light emitting element that selectively emits light of a third color; a controller configured to produce first, second and third pixel data in dependence on a video signal received from a video source; a driver configured to one or more micro-mirror(s) that project an image in dependence on the light of first, second and third colors emitted by the first, second and third light emitting elements; wherein the controller is configured to control intensities of the light emitted by the first, second and third light emitting elements, at least in part, by controlling duty-cycles of pulses included in pixel periods associated with the first, second and third drive signals; and wherein at least one of the controller or the driver is configured to cause each of the first, second and third drive signals to include a same number of multiple pulses within each said pixel period of the first, second and third drive signals.
