There is provided a projector comprising, a light source unit having a laser light emitter and a projection light producing device for converting the laser light into projection light, a display unit and a light guiding optical system which forms a projection optical path along which light from the light source unit is guided to the display device, the projector comprising a partial light separation unit which reflects or transmits part of light emitted from the projection light converting device of the light source unit so as to separate the part of the light to an optical path which is different from the projection optical path, a photosensor which is disposed on the optical path which is separated and changed by the partial light separation unit, a light intensity determination unit which detects an light intensity of the laser light which is separated by the partial light separation unit so as to determine whether or not the light intensity exceeds a threshold, and a light source control unit which stops the emission of the laser light emitter based on the result of the determination of the light intensity determination unit. |
