Abstract
A laser light source projector includes a plurality of light sources of color groups each including a plurality of laser light sources. The laser light source projector projects an image by driving the laser light sources in each of the color groups. In response to change of the light output characteristics of one or a plurality of laser light sources in an arbitrary color group, light output from a remaining laser light source in the arbitrary color group is adjusted, thereby keeping white balance constant.
