In the left figure of FIG. 4, two exhibitions (Tohoku exhibition, Kyushu exhibition) are held simultaneously, and in the right figure of FIG. 4, three exhibitions (IT exhibition, wireless exhibition, logistics exhibition) are held simultaneously. The Tohoku and Kyushu exhibitions are like local product exhibitions, for example.

  By the way, depending on the scale of an event (for example, an exhibition), there are cases where it is desired to project the same image (for example, guidance information) in a plurality of areas. For example, the Tohoku exhibition of 3/25 to 3/27 is a case where three areas A, B, and C are used, and the same image is projected from the projectors 10 of the areas A, B, and C. For example, in the Kyushu exhibition of 3/25 to 3/27, there are cases where two areas D and E are used and the same image is desired to be projected from the projectors 10 in the areas D and E.

  On the other hand, in 4/1 to 4/2, IT exhibition uses two areas A and B, logistics exhibition uses area C, wireless exhibition uses area D, and area E is not used.

(At least one of E) is transmitted to the processing device 20 in advance (before the projector 10 is used). The processing device 20 transmits image data to the projector 10 specified by the information. The projector 10 that has received the image data projects an image corresponding to the image data.

  For example, on March 25, 2015, the processing apparatus 20 sends the same image data simultaneously to three projectors 10 individually installed in the three areas (venues) A, B, and C of the Tohoku Exhibition. The same image data is simultaneously sent to the projectors 10 installed in the two areas (venues) D and E.

  Here, when the user performs an operation to open the input screen shown in FIG. 7 on the display, the processing device 20 receives reservation information for the day from the management device 30 (information for specifying the projector 10 whose day is the current use day). ) Is displayed.

  When the user selects an item of an exhibition (for example, at least one of Tohoku and Kyushu exhibitions) to be projected on the input screen of FIG. The projector 10 installed in each area receives the image data from the processing device 20 and projects an image corresponding to the image data. At this time, if the same image data is simultaneously transmitted to the plurality of projectors 10 of the exhibition, the same image is simultaneously projected in the plurality of areas of the exhibition. Further, by selecting the item “disconnect” on this screen, communication with the projector 10 of the selected exhibition can be disconnected.

  Hereinafter, an example of an operation sequence of the projector system 1000 will be described. FIG. 8 shows a series of procedures (sequences) 1 to 7 for performing projection from the projector 10 on March 25, 2015, with the reservation information shown in FIG.
