Patent ID: 7876285

Claim:
A projection system comprising: plural projectors respectively including: an image-data restoring unit that converts transmission data transmitted from a information processing apparatus to image data; an individual image correction processing unit that applies individual kinds of image correction processing corresponding to each of the projectors to the image data converted by the image-data restoring unit; and an image projecting unit that modulates a light beam emitted from a light source on the basis of corrected image data corrected by the individual image correction processing unit and projects an image; a signal transmitting device that connects an information processing apparatus and the respective projectors and transmits the transmission data generated by the information processing apparatus to the respective projectors; and the information processing apparatus including: a common image correction processing unit that generates image data obtained by applying image correction processing common to the respective projectors to the image source in order to cause each of the projectors to display an appropriate image; and an image-data transmitting unit that converts the image data generated by the common image correction processing unit into the transmission data and transmits the transmission data to the respective projectors through the signal transmitting device.
