MULTIPROJECTION DISPLAY SYSTEM AND SCREEN FORMING METHOD

摘要

A multiprojection display system is provided with a plurality of cameras disposed in positions in which the cameras can capture images of image-capturing regions including marks having reflectances to visible light higher than that of the projection region or support members having reflectances to visible light different from that of the projection region. An image processing circuit detects the specific positions and the positions of the vertices of the projected images from the data relating to the image captured by the cameras and outputs data representing the detected specific positions and data relating to the image edges representing the detected positions of the vertices of the projected images. A control unit adjusts the positions and sizes of the projected images so that the positions of the vertices of the projected images are aligned with the specific positions corresponding to the vertices if the positions of the vertices of the projected images are not aligned with the specific positions.
