Abstract
A technique can reduce the time and effort of a user to project a projection image in a projection area on a projection surface. A projector includes: a projection unit projecting a projection image onto a projection surface; an image pickup unit picking up an image of the projection surface and generating a picked-up image; a detection unit detecting a position of a removable object arranged at the projection surface, based on the picked-up image; and an adjustment unit adjusting a projection position of the projection image on the projection surface, based on the position of the object.
