Abstract
(EN)
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.

L'invention concerne un dispositif projecteur (100) constituant un système de projection et équipé, sur ses faces gauche, droite, supérieure et inférieure, de quatre ensembles de sections (101, 102, 103, 104) d'émission infrarouge et de sections (105, 106, 107, 108) de réception infrarouge utilisant des capteurs bidimensionnels PSD. Chaque dispositif projecteur (100) détecte l'existence d'autres dispositifs projecteurs installés à droite, à gauche, au-dessus et au-dessous de celui-ci en recevant des rayons infrarouges émanant des sections d'émission infrarouge d'autres dispositifs projecteurs au moyen des sections de réception infrarouge (105, 106, 107, 108), et établit des communications entre les sections (101, 102, 103, 104) d'émission infrarouge du dispositif (100) et les sections de réception infrarouge des autres dispositifs projecteurs, ainsi qu'entre les sections (105, 106, 107, 108) de réception infrarouge et les sections d'émission infrarouge des autres dispositifs projecteurs. Un dispositif projecteur (100) situé à une position prédéterminée joue le rôle de maître et communique avec les autres dispositifs projecteurs, spécifiant ainsi automatiquement le numéro d'identification de chaque dispositif projecteur (100).

 プロジェクションシステムを構成するプロジェクタ装置(100)は、2次元PSDセンサを使った赤外線送信部(101,102,103,104)と赤外線受信部(105,106,107,108)を上下左右に4組備えている。各プロジェクタ装置(100)は、上下左右に設置された他のプロジェクタ装置の赤外線送信部からの赤外線を赤外線受信部(105,106,107,108)で受けることによりその存在を検出し、自装置の赤外線送信部(101,102,103,104)と他のプロジェクタ装置の赤外線受信部間、及び、自装置の赤外線受信部(105,106,107,108)と他のプロジェクタ装置の赤外線送信部間の通信を確立する。そして、予め定められた位置のプロジェクタ装置(100)がマスタとなり、他のプロジェクタ装置と通信していくことによって、各プロジェクタ装置(100)の認識番号を自動的に設定する。
