1. An apparatus comprising:

  • a MEMS scanner including a biaxial MEMS mirror or a pair of uniaxial MEMS mirrors;

    a controller communicatively coupled to the MEMS scanner and configured to control rotation of the biaxial MEMS mirror or the pair of uniaxial MEMS mirrors of the MEMS scanner;

    a plurality of light sources each of which comprises one or more light emitting elements;

    a plurality of light source drivers, each of which is configured to selectively drive a respective one of the light sources to thereby produce a respective light beam that is directed towards and incident on the biaxial MEMS mirror or one of the pair of uniaxial MEMS mirrors; and

    an image processor communicatively coupled to each of the light source drivers and configured tocause at least two of the light source drivers to drive at least two of the light sources to thereby produce at least two light beams to raster scan, by the MEMS scanner, a first portion of an image; and

    cause only one of the light source drivers to drive only one of the light sources to thereby produce only one light beam to raster scan, by the MEMS scanner, a second portion of the image.
