Abstract

A projection system which arranges n×m projection images and forms one composite projection image on a projection surface includes: n×m projectors; an operation unit which accepts an operation by a user; and a control unit which controls the projection by each of the n×m projectors. The control unit causes a reference image showing a reference point common to a plurality of projection areas to be projected in an overlap area where the plurality of projection areas overlap each other, and causes each of a plurality of projectors projecting the projection image in the overlap are where the reference image to be moved is projected, to execute geometric correction of the projection image in such a way that the reference image moves to a position on the projection surface designated by the user by the operation via the operation unit, and to project the projection image.
