Abstract
A laser projector for scanning a laser beam output by a multimode laser light source and displaying an image includes a laser driving unit to drive the multimode laser light source so that two-dimensional output patterns of a shape of the laser beam are different in each display frame. The laser driving unit applies to the multimode laser light source a driving waveform pattern which has the same product of an output intensity and output time of a laser light source during a display time of one dot and which includes an output intensity and output time different in each display frame.
