Abstract:
This projector includes a laser beam generation portion emitting a laser beam on the basis of an input image signal, a projection portion scanning the laser beam, a light detection portion detecting the laser beam reflected by a detection object, and a control portion controlling the laser beam generation portion to project a detection guide beam, different from the laser beam corresponding to the input image signal, for detection by the light detection portion when determining that detection of the laser beam corresponding to the input image signal by the light detection portion is unexpectable on the basis of color information of the input image signal.
