PROBLEM TO BE SOLVED: To provide a technique for transferring connection information among a plurality of projectors to be used for connecting to a network, using a method hard to receive the influence of positional relationship among the plurality of projectors, with a small user operation load.SOLUTION: A projector 10-1 includes: projection means for projecting an image on a screen 40; first projection control means for changing the projection direction of the projection means to a plurality of directions and projecting a first identification image; imaging means for imaging the screen 40; first detection means for imaging the projected first identification image by a projector 10-2 and detecting, from the image imaged by the imaging means, a second identification image projected on the imaging area of the imaging means by the projector 10-2; and second projection control means for projecting a third identification image, indicative of connection information to be used to connect to a network NW, using the projection direction as a direction associated with a position in which the second identification image is detected.SELECTED DRAWING: Figure 1 |
