A scanning projection apparatus is provided with a first light source module which includes a laser light source to emit a laser beam and a mirror unit which can be oscillated. Further, a light deflection unit which performs a two-dimensional scanning with the laser beam emitted from the first light source module by the mirror unit, a light detection unit which detects a distance from the mirror unit to an image projection surface or a difference in distance in the image projection surface, and a control unit which controls an oscillation angle of the mirror unit based on distance information from the light detection unit are included. |
