More Information
Summary:A projection system includes projection units collectively projecting an image as a whole on a projection area; a generation unit generating correction images including correction points which are used for detecting distortions of projection images based on designated relationships; and a compensation coefficient calculation unit calculating compensation coefficients, based on correction captured images acquired from the correction images on the projection area. Further, margin parts are generated in the correction images in a manner so that parts defining the correction points in the correction images are projected within the projection area while the parts defining correction points in the correction images corresponding to the projection units that are next to each other are overlapped.
