Abstract
A projector includes: a projection unit projecting a projection image onto a projection surface where an object is located, the object defining a projection area where the projection image should be projected; an image pickup unit picking up an image of the projection surface and thus generating picked-up image information representing a picked-up image; an object detection unit detecting the object, based on the picked-up image information; and a projection control unit controlling a brightness of the projection image, based on a result of detection of the object.
