Abstract
A projector includes an image projection section adapted to let a light pass through a projection lens to project a projection image on a screen, an end part extraction section adapted to detect end parts of the screen and the projection image, a lens shift adjustment mechanism adapted to move the projection lens, an operation receiving section adapted to receive an operation of moving the projection image, and a control section adapted to move the projection lens so that the projection image moves in a first direction in response to the operation, and the control section changes a moving speed at which the projection image moves in the first direction when an inter-end part distance between the end part of the screen and the end part of the projection image gets within a first range while the control section is moving the projection image in response to the operation.
