In the following description, the identifier set in the remote controller 20 is “3”, the identifier set in the projector 10A is “1”, the identifier set in the projector 10B is “2”, and is set in the projector 10C. The operation example will be described assuming that the identifier is “3”. Further, an operation example will be described assuming that the signal transmitted by the remote controller 20 is received by the projector 10A and not received by the projector 10B and the projector 10C.

  When the button is operated, the remote controller 20 transmits an infrared light signal including a set identifier “3” and a code corresponding to the operated button. The infrared light signal transmitted by the remote controller 20 is received by the light receiving unit 170A. The light receiving unit 170A converts the received infrared light into an electrical signal, and supplies the identifier “3” and an electrical signal representing a code corresponding to the operated button to the control unit 110A.

  When an electric signal is supplied from light receiving unit 170A, control unit 110A causes the light emitting diode of light receiving unit 170A to blink for a predetermined time (FIG. 4: step SA1). Also, the control unit 110A determines whether the identifier included in the supplied signal is the same as the identifier stored in the storage unit 120A (step SA2). Here, since the identifier stored in the storage unit 120A is “1”, the control unit 110A determines that the identifier included in the supplied electrical signal is not the same as the identifier stored in the storage unit 120A. Judgment is made (NO in step SA2).

  When the control unit 110A determines that the identifier included in the supplied electrical signal is not the same as the identifier stored in the storage unit 120A, the confirmation message confirming whether the signal transmitted by the remote controller 20 has been received. The (confirmation signal) is transmitted to the other projectors 10B and 10C that collaborately project the entire image with reference to the IP address stored in the storage unit 120A (step SA3).

  When the communication unit 180B receives this confirmation message, the control unit 110B determines whether or not the signal from the remote controller 20 has been received within a predetermined time in the past from the time when the confirmation message was received (see FIG. 5: Step SB1). If the signal from remote controller 20 has not been received (NO in step SB1), control unit 110B controls communication unit 180B to transmit a response message notifying that it has not been received to projector 10A (step SB1). SB2).

  When communication unit 180C receives the message transmitted by projector 10A, control unit 110C has received a signal from remote controller 20 within a predetermined time in the past from the time this message was received. Judgment is made (step SB2). When the signal from remote controller 20 has not been received (NO in step SB1), control unit 110C controls communication unit 180C to transmit a response message notifying that it has not been received to projector 10A (step SB1). SB2).

When communication unit 180A receives the response message transmitted from projector 10B, control unit 110A determines whether or not the received response message indicates that it has been received (FIG. 6: step SC1). When the received response message does not indicate that the received response message has been received (NO in step SC1), control unit 110A transmits the response message with the identifier and code included in the signal supplied from light receiving unit 170A. The communication unit 180A is controlled and transmitted to the projector 10B that has been performed (step SC2). When communication unit 180A receives the response message transmitted from projector 10C, control unit 110A determines whether the received response message indicates that it has been received (step SC1). When the received response message does not indicate that the received response message has been received (NO in step SC1), control unit 110A transmits the response message with the identifier and code included in the signal supplied from light receiving unit 170A. The communication unit 180A is controlled and transmitted to the projector 10C (step SC2).

  When the communication unit 180B receives the identifier and code transmitted from the projector 10A, the control unit 110B determines whether the supplied identifier is the same as the identifier stored in the storage unit 120B (FIG. 7: step). SD1). Here, since the received identifier is “3”, the identifier stored in the storage unit 120B is “2”, and the received identifier is different from the stored identifier (NO in step SD1), the control unit 110B does not perform processing corresponding to the code received by the communication unit 180B.

When communication unit 180C receives the identifier and code transmitted from projector 10A, control unit 110C determines whether the supplied identifier is the same as the identifier stored in storage unit 120C (step SD1). ). Here, the received identifier is “3”, the identifier stored in the storage unit 120C is “3”, and the received identifier is the same as the stored identifier (YES in step SD1). The control unit 110C performs processing corresponding to the code received by the communication unit 180B (step SD2).

In addition, 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 (step SA2). Since the identifier stored in the storage unit 120A is “1”, the control unit 110A determines that the identifier included in the supplied electrical signal is the same as the identifier stored in the storage unit 120A. (YES at step SA2).

  When it is determined that the identifier included in the supplied electrical signal is the same as the identifier stored in the storage unit 120A, the control unit 110A performs a process corresponding to the code included in the supplied signal. Perform (step SA4). In addition, the control unit 110A controls the video processing unit 150 and the projection unit 140 so that the OSD of the icon that notifies that the processing according to the operation performed on the remote controller 20 has been executed is projected (displayed) ( Step SA5). When this control is performed, an OSD of an icon for notifying that processing corresponding to the operation performed by the remote controller 20 has been executed is projected within the image area projected by the projector 10A.

  As described above, according to the present embodiment, even if the signal from the remote controller 20 does not reach the projector 10 storing the same identifier as the identifier transmitted by the remote controller 20, the identifier transmitted by the remote controller 20 is the same. In the projector 10 storing the identifier, processing corresponding to the code transmitted by the remote controller 20 can be performed. Further, according to the present embodiment, it is possible to notify the user of the projector 10 that has received a signal from the remote controller 20 and the projector 10 that has executed processing corresponding to the code transmitted by the remote controller 20. Further, according to the present embodiment, the mode of notifying the projector 10 that has received the signal from the remote controller 20 is blinking of the light-emitting diode, and the projector 10 that has executed the process corresponding to the code transmitted by the remote controller 20 is used by the user. Since the notification mode is the OSD display and the notification mode is different, the projector 10 that has received the signal from the remote controller 20 and the projector 10 that has executed the process can be easily distinguished.
