PROBLEM TO BE SOLVED: To realize control of a laser projector without interrupting irradiation of laser over the whole projection surface in every intrusion detection by making another light source for detecting intrusion of an object into an irradiation area unnecessary, and taking a safety measure for avoiding the risk that irradiation of laser hurts the retina of the eye only in the case that the intruding object is a human.SOLUTION: By detecting intrusion of an object based on face image recognition of an image obtained by photographing an irradiation area of laser with a camera, another light source is made unnecessary and whether or not the intruding object is a human is determined, and when the intruding object is the human, irradiation of the laser is controlled so as not to irradiate the laser only to parts of the eyes and the face. |
