PROBLEM TO BE SOLVED: To provide a multiprojection system in which position deviation, distortion or color shift of a projection image is corrected in real time even at an arbitrary observation position if a shape of a screen is not known. SOLUTION: A multiprojection system for forming one large image by sticking together images projected on a screen by a plurality of image projectors 1A, 1B, comprises: image acquisition means 3A, 3B for acquiring parallax image data by capturing the images which are projected on the screen 2 by the image projectors 1A, 1B, from positions of which the relative positional relationship is known; an image correction data calculation means 4 for calculating correction data for correcting images inputted to the image projectors 1A, 1B by estimating three-dimensional positions of points of the images projected on the screen 2 based on the acquired parallax image data and information on the relative positional relationship; and an image correction means 5 for correcting the images inputted to the image projectors 1A, 1B based on the calculated correction data.
