PROBLEM TO BE SOLVED: To make it possible to check a larger number of contents of projection when images are projected from a plurality of projectors and an overlapping area is generated.SOLUTION: A projection device photographs a screen including a projection data group projected from a plurality of projectors and determines whether or not an overlapping area has been detected from a photographed image. As a result of the determination, when an overlapping area has been detected, the projection device detects, from a free area other than the overlapping area, a rectangular area in which projection can be performed and determines a projection area. When projection data being projected does not fall into the determined projection area despite movement of the projection data, the projection device controls a projection part to reduce an image being projected and project the reduced image in the determined projection area.SELECTED DRAWING: Figure 1 |
