Abstract
A projector includes: a laser beam generator configured to emit a laser beam according to an image signal; a beam splitter configured to split the laser beam into a first laser beam toward the first projection plane and a second laser beam toward the second projection plane; a scanning unit, disposed between the laser beam generator and the beam splitter, configured to scan the laser beam from the laser beam generator toward the beam splitter; a light receiver configured to receive reflected light of the first laser beam; a computation portion configured to compute positional information indicating a position of an obstacle located in an optical path of the first laser beam based on a light receiving result by the light receiver; and a display control portion configured to change the image signal so that a pointer is displayed in the image based on the positional information.
