<P>PROBLEM TO BE SOLVED: To provide a projection system can reduce the movable range of a regulation mechanism and adjust the position of a projected image following variation accompanied with temperature change during activation. <P>SOLUTION: The projection system includes two projectors 3 equipped with an image projection mechanism 31, a CCD camera, and a PC 5. The image projection mechanism 31 includes a regulation mechanism 315 for adjusting a projected position of image light mechanically. The PC 5 includes a correction information generating portion 52 for generating correction parameters for rectifying image databased on an image photographed with the CCD camera, a temperature equilibrium determining portion 53 for determining whether temperature at each image projection mechanism 31 is changed or not, an image correction portion 54 for rectifying the image databased on the correction parameter, and an adjustment information outputting portion 56 for outputting adjustment information for prompting adjustment by the regulation mechanism 315, if it is determined by the temperature equilibrium determining portion 53 that temperature at each image projection mechanism 31 is not changed. <P>COPYRIGHT: (C)2010,JPO&INPIT |
