Abstract
An image display device includes a laser light source, a controller, a temperature acquisition unit, and an image forming unit. The laser light source emits a plurality of laser beams including a red laser beam, a green laser beam, and a blue laser beam. The controller controls lighting of the laser light source. The temperature acquisition unit obtains temperature information with respect to the laser light source. The image forming unit creates an image from the plurality of laser beams emitted from the laser light source. The controller varies a light output ratio between the plurality of laser beams, based on the temperature information obtained by the temperature acquisition unit.
