Control method for image projection system, and image projection system

Abstract

A projector includes a correction information generation unit, image information correction unit, and image projection unit. The generation unit sets a first coordinate in a two-dimensional projection formed by flattening out a three-dimensional projection surface onto a plane. The generation unit arranges a first quadrilateral having a first aspect ratio within the two-dimensional projection, based on the first coordinate as a reference position, so that the first quadrilateral comes into contact with an outline of the two-dimensional projection. The generation unit determines whether the first quadrilateral is in contact with the outline at two or more points. When the first quadrilateral is determined as being in contact with the outline at two or more points, the correction unit corrects image information, based on the first quadrilateral, and thus generates corrected image information. The image projection unit projects an image based on the corrected image information onto the projection surface.
