Abstract
Provided is a multiprojection display system that includes a plurality of cameras installed in positions in which the cameras can capture images of image-capturing regions including marks whose visible light reflection ratio is higher than the projection region or support members whose ratio to reflect visible light is different from the projection region. An image processing circuit detects prescribed positions and positions of vertexes of projected images from data indicating the images captured by the cameras, and outputs data indicating the detected prescribed positions and image edge data indicating the positions of the vertexes of the projected images. A control unit adjusts, when the Positions of the vertexes of the projected images shift from the prescribed positions corresponding to the vertexes, the positions and sizes of the projected images so that the positions of the vertexes of the projected images can be matched with the prescribed positions.
