A projection system for projecting an output image. The projection system comprises a plurality of laser diodes, each laser diode operable to generate a light beam having a selected intensity in response to a control voltage and a control current and combiner optics for combining light beams received from the plurality of laser diodes to generate an output light beam. A MEMS mirror module receives the output light beam from the combiner optics and generates a scanning light beam that forms the output image on a projection surface. A controller adjusts the control voltage associated with each of the plurality of laser diodes for a first line of pixel data in response to a determination of a level of contrast associated with the first line of pixel data.
