Abstract
A projector includes a laser beam scanning portion, a light detecting portion, and a control portion performing control of predicting a prediction region where a detection object exists on the basis of detection of the detection object, changing a modulation pattern of a laser beam when the laser beam is scanned on the prediction region, acquiring the position of the detection object on the basis of reflected light of the laser beam emitted in a detection object detection pattern, and setting the position of the detection object to an indication position.
