An information processing device that includes: a correction parameter storage unit that stores therein an individual correction parameter for each of a plurality of projectors connected to the information processing device for use to individually perform an image correction process of enabling appropriate image display by each of the projectors; a correction parameter combination process unit that calculates a combined correction parameter by combining together the individual correction parameters for the projectors; a combined correction image data generation unit that generates combined correction image data by performing the image correction process with respect to an incoming image source based on the combined correction parameter; and an image data transmission unit that transmits the combined correction image data to any of the projectors.
