摘要： A scanning projector system includes a controller, a driver and one or more micro-mirror(s). The controller produces first, second and third pixel data in dependence on a video signal. The driver drives first, second and third light emitting elements in dependence on the first, second and third pixel data, to thereby emit light of first, second and third colors. The micro-mirror(s) project an image in dependence on light beams produced in dependence on the light of the first, second and third colors. The controller controls intensities of the light emitted by the 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. To reduce color shifts, the controller and/or the driver causes at least two pulses to be included in each pixel period associated with drive signals used to drive the light emitting elements.

To reduce color shifts due to inter-pixel interference, the controller and/or driver causes at least one timing guard band per pixel period associated with each instance of the pixel data.
