A laser projector including a laser light source, a scan unit to scan the laser beam, a scan signal generation unit to generate a pulse signal, a drive unit to drive the scan unit and a pulse pattern adjustment unit to adjust a pulse pattern, wherein the pulse pattern adjustment unit adjusts the pulse pattern to a first pulse pattern for adjusting the swing amount from a first swing amount to a second swing amount in a projection interval, adjusts the pulse pattern to a second pulse pattern for adjusting the swing amount from the second swing amount back to the first swing amount in a first-stage interval in a non-projection interval, and adjusts the pulse pattern to a third pulse pattern for keeping the swing amount at the first swing amount in a second-stage interval in the non-projection interval until a scan position returns to the projection interval. |
