Laser beam display device

A laser beam display device in which semiconductor laser light emitted from a laser diode is modulatedly driven by a video signal, and an image corresponding to the video signal is displayed by scanning the emission beam of the laser diode, the laser beam display device comprising:

• a dimming setting input unit into which any one of the dimming values of a plurality of dimming steps are input;
• a first dimming processing unit having a plurality of dimming look-up tables that store dimming amounts regarding the respective dimming steps with the corresponding gradation levels as indexes;
• a second dimming processing unit having one gain look-up table that holds gains regarding the respective dimming steps and a multiplier that creates the indexes for the respective diming look-up tables by multiplying the video signal by the gains;
• and
• a light source drive unit that drives the laser diode on the basis of reference results obtained by referring to the dimming look-up tables of the first dimming processing unit,
• wherein the luminance of the emission beam of the laser diode, which corresponds to the video signal, is dimmed in accordance with a dimming setting input from the dimming setting input unit.
