摘要： A detection surface of an optical detector is divided into regions C, E, F, G, and H. The optical detector outputs detection signals corresponding to the amounts of light incident on the respective regions. A position detection controller calculates an image projection position based on timing at which a laser beam is incident on region C. A laser control circuit adjusts the intensity of the laser beam emitted by a laser based on laser beam intensities detected in regions E to H arranged around region C.
