<P>PROBLEM TO BE SOLVED: To provide a projector system relieving a burden on a user in order to project an appropriate video image to a screen. <P>SOLUTION: In a projector 100, the video image is projected to the screen 291 of a screen unit 200 via a lens 190 from a video output part 110. In the screen unit 200, a singularity or a plurality of illuminance sensors 293 are provided near the screen 291. From the screen unit 200, a value of illuminance detected by each illuminance sensor 293 is transmitted via a radio communication part 202. The projector 100 receives a detected value of the illuminance transmitted from the screen unit 200 by a radio communication part 102. Then, in the projector 100, brightness of the video image to be projected to the screen 291 is adjusted in the video output part 110 according to the received detected value of the illuminance. <P>COPYRIGHT: (C)2009,JPO&INPIT |
