摘要:
A laser projector is provided. A laser light source is configured to emit laser light. A scanning section is configured to scan a projection surface in a horizontal direction and a vertical direction with the laser light emitted from the laser light source, thereby forming an image on the projection surface. A generating section is configured to generate a pulse signal. A driving section is configured to reciprocate the scanning section in the horizontal direction in accordance with the pulse signal generated by the generating section. An adjusting section is configured to adjust a pulse pattern of the pulse signal generated by the generating section so as to change a scanning angle range of the scanning section in the horizontal direction.
