When the specifying unit 1002 specifies a projector 10 other than itself, the setting unit 1005 sets itself so that it does not operate according to the code transmitted from the remote controller 20, and the receiving unit 1004 receives the instruction signal. If it does, it sets itself so that it operates according to the code transmitted from the remote controller 20. The process execution unit 1006 executes a process according to the code included in the signal supplied from the light receiving unit 170 according to the setting performed by the setting unit 1005.

(Operation example of embodiment)
Next, an operation example of this embodiment will be described. In the following description, the identifier set in the remote controller 20 is “1”, the identifier set in the projector 10A is “1”, and the identifier set in the projectors 10B to 10D is “2”. An operation example will be described on the assumption.

  When a button is operated on the remote controller 20, the remote controller 20 transmits an infrared signal including a set identifier “1” and a code corresponding to the operated button. The infrared light signal transmitted by the remote controller 20 is received by the light receiving units 170A to 170D. The light receiving unit 170A converts the received infrared light into an electrical signal, and supplies an identifier “1” and an electrical signal representing a code corresponding to the operated button to the control unit 110A. The light receiving unit 170B supplies an identifier “1” and an electric signal representing a code corresponding to the operated button to the control unit 110B, and the light receiving unit 170C receives the identifier “1” and the operated button. The light signal unit 170D supplies an identifier “1” and an electric signal representing a code corresponding to the operated button to the control unit 110D.

  When the signal is supplied from the light receiving unit 170, the control unit 110 determines whether the identifier included in the supplied signal is the same as the identifier stored in the storage unit 120. Since the identifier stored in the storage unit 120B, the storage unit 120C, and the storage unit 120D is “2”, the control unit 110B, the control unit 110C, and the control unit 110D store the identifier included in the supplied electrical signal, It is determined that the identifier stored in unit 120 is not the same. The control unit 110B, the control unit 110C, and the control unit 110D are included in the supplied electrical signal when the identifier included in the supplied electrical signal is not the same as the identifier stored in the storage unit 120. Do not perform processing corresponding to the code.

  On the other hand, since “1” is stored as an identifier in the storage unit 120A and the identifier included in the supplied electrical signal is “1”, the control unit 110A includes the identifier included in the supplied electrical signal, It is determined that the identifier stored in the storage unit 120 is the same. When the identifier included in the supplied electrical signal is the same as the identifier stored in storage unit 120, control unit 110A performs processing corresponding to the code included in the supplied electrical signal. For example, when the user performs an operation for adjusting the image quality of the projected image on the remote controller 20, the image quality of the projector 10 </ b> A storing the identifier “1” transmitted by the remote controller 20 in the storage unit 120 is the user image quality. It is adjusted according to the operation.

  Next, an operation example when changing the projector 10 operated by the remote controller 20 will be described with reference to the sequence diagram of FIG. First, when the user performs an operation for instructing display of a menu screen for changing the projector 10 operated by the remote controller 20 with the remote controller 20, an infrared light signal is output from the remote controller 20 according to the performed operation. It is transmitted to the projectors 10A to 10D (step S1). When the light receiving unit 170A receives this signal, the control unit 110A refers to the IP address stored in the storage unit 120A for the message requesting the identifier and the region information, and cooperates to project the entire image. Transmit to the projectors 10B to 10D (step S2).

  When the communication unit 180 of the projectors 10B to 10D receives this message, the control unit 110B controls the communication unit 180B with the identifier “2” and the area information “(1, 2)” stored in the storage unit 120B. The control unit 110C controls the communication unit 180C to transmit the identifier “2” and the area information “(2, 1)” stored in the storage unit 120C to the projector 10A (step S3). The control unit 110D transmits the identifier “2” and the area information “(2, 2)” stored in the storage unit 120D to the projector 10A by controlling the communication unit 180D (step S4) (step S4). S5).

  When the communication unit 180A receives the identifier and area information transmitted from the projectors 10B to 10D, the control unit 110A receives the identifier and IP address stored in the storage unit 120A, and the received identifier and IP address. They are displayed side by side based on the information (step S6).

  FIG. 5 is an example of a screen (selected image) projected by the projector 10A here. The area information stored in the storage unit 120A is “(1, 1)” and represents the first row and the first column. Therefore, the identifier “1” and the IP address stored in the storage unit 120A are 1 row 1 It is displayed in the column (upper left) area. The IP address of the projector 10B, the area information “(1,2)” and the identifier “2” received from the projector 10B are displayed in the area of the first row and the second column (upper right), and the IP address of the projector 10C, the projector The area information “(2, 1)” and the identifier “2” received from 10C are displayed in the area of the second row, first column (lower left), the IP address of the projector 10D, and the area information “(2) received from the projector 10D. , 2) "and the identifier" 2 "are displayed in the area of the second row and the second column (lower right).

  Next, when the user performs an operation of selecting any region displayed in FIG. 5 on the remote controller 20, an infrared light signal is transmitted from the remote controller 20 according to the performed operation (step S7). ). When the light receiving unit 170A receives this signal, the control unit 110A controls each unit so that a screen in which the selected area is displayed in reverse is projected, for example, as shown in FIG. 6 (step S8).

  As shown in FIG. 6, when the user performs an operation for determining the area on the remote controller 20 in a state where the area of the first row and the second column is selected, the infrared light is transmitted from the remote controller 20 according to the performed operation. An optical signal is transmitted (step S9). When the light receiving unit 170A receives this signal, the control unit 110A includes the identifier “1” stored in the storage unit 120A, and displays a message (instruction signal) for requesting the change of the identifier in the highlighted area. It transmits to the projector 10B of the IP address that has been displayed (step S10). Also, the control unit 110A overwrites the identifier “1” stored in the storage unit 120A with the identifier “2” displayed in the highlighted area (step S11). Also, the displayed screen of FIG. 6 is deleted (step S12).

  When the communication unit 180B receives the message requesting the change of the identifier, the control unit 110B overwrites the identifier stored in the storage unit 120B with the identifier “1” included in the received message (step S13). . Through the above operation, the identifier stored in the projector 10A and the identifier stored in the projector 10B are switched, the identifier stored in the projector 10A is “2”, and the identifier stored in the projector 10A is “1”. "

  When the user operates the remote controller 20 after the identifier stored in the projector 10A and the identifier stored in the projector 10B are switched, “2” is stored as the identifier in the storage unit 120A, and the remote controller 20 Since an identifier different from the identifier “1” to be transmitted is stored, the control unit 110A does not perform processing corresponding to the code included in the signal supplied from the light receiving unit 170A. On the other hand, “1” is stored as the identifier in the storage unit 120B, and the same identifier as the identifier “1” transmitted by the remote controller 20 is stored. Therefore, the control unit 110B receives the signal supplied from the light receiving unit 170B. Performs processing corresponding to the code included in.

  As described above, according to the present embodiment, it is possible to operate one of the plurality of projectors 10 without inputting an identification number for each operation. Further, when operating a plurality of projectors 10 with one remote controller 20, the projector 10 to be operated can be easily set on the screen to be projected.

[Modification]
As mentioned above, although embodiment of this invention was described, this invention is not limited to embodiment mentioned above, It can implement with another various form. For example, the present invention may be implemented by modifying the above-described embodiment as follows. In addition, you may implement each embodiment mentioned above and the following modifications, combining one or more suitably.

  In the above-described operation example, the identifier stored in one projector 10 is the same as the identifier of the remote controller 20, and the identifier stored in the other projector 10 is the same identifier. However, the configuration is limited to this configuration. It is not something. For example, the identifier stored in the storage unit 120A is “1”, the identifier stored in the storage unit 120B is “2”, the identifier stored in the storage unit 120C is “3”, and stored in the storage unit 120D. In the projector 10 that does not store the same identifier as the identifier of the remote controller 20, such as “4”, the stored identifier may be different.

In the present invention, each of the projectors 10 </ b> A to 10 </ b> D may store the same identifier as the identifier transmitted by the remote controller 20. In the case of this configuration, the storage unit 120 stores setting information indicating whether to accept a signal from the remote controller 20. For example, when the projector 10A accepts a signal from the remote controller 20 and the projectors 10B to 10D do not accept a signal from the remote controller 20, the storage unit 120A stores “on” as setting information, and the storage unit In 120B, the storage unit 120C, and the storage unit 120D, “off” is stored as the setting information.
The control unit 110 operates according to the setting information stored in the storage unit 120 when the light receiving unit 170 is supplied with an identifier of the remote controller 20 and an electrical signal representing a code corresponding to the operated button. To do. When the setting information stored in the storage unit 120 is “on”, the control unit 110 performs a process corresponding to the code included in the supplied electrical signal. When the setting information stored in the storage unit 120 is “off”, the process corresponding to the code included in the supplied electric signal is not performed.

  That is, as described above, when the setting information stored in the storage unit 120A is “on” and the setting information stored in the storage unit 120B, the storage unit 120C, and the storage unit 120D is “off”, the projector 10A operates according to the operation performed by the remote controller 20, and the projectors 10B to 10D do not perform the operation according to the operation performed by the remote controller 20.

Further, in this modification, when an operation for instructing display of a screen for changing the projector 10 operated by the remote controller 20 is performed, the projector 10A acquires setting information from the other projectors 10B to 10D. In the screen of 5, the setting information is displayed instead of the identifier.
After the screen for changing the projector 10 operated by the remote controller 20 is displayed, when the user selects an area of the displayed screen and determines the area on the remote controller 20, the control unit 110A transmits a message instructing to turn the setting information “on” to the projector 10 having the IP address displayed in the highlighted area. Further, the control unit 110A rewrites the setting information stored in the storage unit 120A to “off”. Thereafter, the projector 10A does not operate even when a signal from the remote controller 20 is received. On the other hand, when the projector 10 that has rewritten the setting information to “on” receives a signal from the remote controller 20, the projector 10 operates according to the received signal.

  In the above-described embodiment, the entire image is projected by the four projectors 10. However, if the number of the projectors 10 that project the entire image is plural, the number of projectors 10 may be other than four. Good. Further, in the above-described embodiment, the four projectors 10 are configured to divide and project the entire image, but each of the four projectors 10 may project the same entire image. Good.
