Abstract: A range of images projected by a first projector group and a range of images projected by a second projector group are set to coincide with each other. A first setting screen including a first region for setting positions of images projected by a respective plurality of projectors included in the first projector group and a second region for setting positions of images projected by a respective plurality of projectors included in the second projector group is displayed. Operation by a user on the first setting screen is received. The positions of the images projected by the respective plurality of projectors included in the first projector group and the positions of the images projected by the respective plurality of projectors included in the second projector group are set.

Abstract: A projector includes: an interface unit that reads multiple types of network setting information stored in a portable information storing medium; an image producing unit that produces, based on the multiple types of network setting information, a network setting selection image from which a network setting used to connect the projector to a network is selected; an input unit through which receives selection information indicating which one of the network settings is selected; a communication unit that connects the projector to the network based on the selected network setting contained in the selection information; and a projection unit that projects the network setting selection image.
