Abstract
An optical scanning projector includes: a raster scanning unit that draws an image in a drawing area on a display surface by scanning beams in a first direction on the display surface while scanning beams in a second direction on the display surface that is orthogonal to the first direction; and a vector scanning unit that draws an image by irradiating beams so as to sequentially form segments each connecting two different points positioned on the display surface.
