Document Type and Number:
WIPO Patent Application WO/2011/001507
Kind Code:
A1
Abstract:
A projector device (100) constituting a projection system is equipped, on the left, right top and bottom sides thereof, with four sets of infrared transmission sections (101, 102, 103, 104) and infrared reception sections (105, 106, 107, 108) that use two-dimensional PSD sensors. Each projector device (100) detects the existence of other projector devices installed to the right and left, above and below thereof by receiving infrared rays transmitted from the infrared transmission sections of other projector devices by the infrared reception sections (105, 106, 107, 108), and establishes communications between the infrared transmission sections (101, 102, 103, 104) of the device (100) and the infrared reception sections of other projector devices, and between the infrared reception sections (105, 106, 107, 108) and the infrared transmission sections of other projector devices. A projector device (100) at a predetermined position works as a master and communicates with other projector devices, thus setting the identification number of each projector device (100) automatically.
