The terminal device 20 is preferably a mobile phone, a smartphone, a tablet terminal, a notebook PC, a head-mounted display, or the like, which is configured to be portable or worn by the user.

The control unit 21 is configured to centrally control the operation of each unit of the terminal device 20 using a CPU, RAM, etc.
Specifically, various display signals are transmitted to the display unit 22 by reading and executing a web application program stored in the storage unit 25 in response to an operation signal input from the operation unit 23 .

The display unit 22 includes a monitor such as an LCD (Liquid Crystal Display), and displays various screens according to instructions from display signals input from the control unit 21.
Specifically, the display unit 22 is capable of displaying, for example, a setting screen for configuring the installation of the photographing device 10.

The operation section 23 is configured with a keyboard with various keys, a pointing device such as a mouse, or a touch panel laminated on the display section 22, and is configured with a touch panel laminated on the display section 22.

Further, the control unit 21 causes the communication unit 24 to transmit an instruction signal to the photographing device 10 when a predetermined instruction operation is performed while the setting screen is displayed.

[Operation of radiation detection system]
Next, the installation setting process of the imaging device 10 that constitutes the radiation detection system 100 will be explained.
The radiation detection system 100 according to the present embodiment allows installation and setting of the imaging device 10 in a facility or the like using the terminal device 20. FIG. 4 is a flowchart showing the installation setting process of the photographing device 10.

Note that, as a premise, in the initial setting state at the time of factory shipment, the photographing device 10 is in a state in which a predetermined operation is possible. That is, in the initial setting state, the photographing device 10 is set with an SSID and a password for operating as a base unit (access point) in wireless communication. It may also be possible to connect to the Internet.

When the control unit 21 of the terminal device 20 transmits a connection request signal to the photographing device 10 according to the user's operation via the operation unit 23, the panel control unit 11 of the photographing device 10 receives this connection request signal ( Step S1).

Next, the panel control unit 11 of the photographing device 10 checks the installation state of the photographing device 10 and determines whether the installation state is “completed” (step S2).
Specifically, the control unit 21 refers to the installation setting information in the storage unit 15 and determines whether settings for all items have been completed. In other words, if all items are determined to be "completed", the installation status is "completed", and if any item is determined to be "unfinished", the installation status is "incomplete". I judge that.
Note that if the items included in the installation setting information are grouped, the installation status may be determined to be "completed" when all items in a given group are determined to be "completed". .

Next, if the installation state is "complete" (step S2: YES), the panel control unit 11 transmits connection permission to the terminal device 20 to establish a connection (step S3), and performs a predetermined operation according to instructions from the terminal device 20. The operation is performed (step S4). For example, an operation such as starting shooting will be performed.

On the other hand, if the installation state is "incomplete" (step S2: NO), the panel control unit 11 determines whether or not the connection request signal from the terminal device 20 includes information regarding the installation (step S5). , if the information regarding the installation is not included (step S5: NO), the panel control unit 11 transmits a connection refusal signal to the terminal device 20 (step S6).
For example, if information regarding photography is included, it is determined that information regarding installation is not included. Therefore, a situation in which photographing or the like is started before the installation settings are completed can be avoided.
In this regard, there has been an increase in the number of cases in which doctors and the like carry only the imaging device 10 with them when making rounds. At this time, it is often not confirmed in advance whether the photographing device 10 can take pictures, and if the photographing device 10 is taken out without realizing that the installation settings have not been completed, the installation settings may not be completed and an erroneous photograph may be taken. There is sex. Therefore, according to the processing in steps S2 (NO), step S5 (NO), and step S6, communication is disabled for the photographing device 10 whose installation settings have not been completed, so that erroneous photographing can be prevented, and the user can identify that the installation settings of the target photographing device 10 have not been completed.
Note that the "information regarding installation" may be any information indicating that it is information regarding the installation of the imaging device 10, and may be, for example, the entire installation setting information, or only a part of the installation setting information.

On the other hand, if information regarding installation is included (step S5: YES), the panel control unit 11 transmits connection permission to the terminal device 20 to establish a connection (step S7), and controls the image capturing device 10 according to the received installation setting information. Settings are made (step S8).
Next, the panel control unit 11 changes the item set in step S8 to cause it to be determined as "end" (step S9), and ends this process.

After the installation status of the photographing device 10 becomes "Complete", the photographing device 10 is set to a mode in which it operates as a base unit or to another base unit, according to the installation setting information ("Wireless LAN operation settings (base unit/slave unit)"). The mode is set to operate as a slave device.
Note that the mode is not limited to the above example, and may be set to, for example, a mode in which wireless communication is disabled.

Note that if the power of the imaging device 10 and/or the terminal device 20 is turned off while the installation state is "incomplete", the imaging device 10 will return to the initial setting state (factory setting state). Also good. In other words, the contents of the items included in the installation setting information return to the initial setting state. For example, when communication with the terminal device 20 is disconnected, the initial setting state is returned.
Furthermore, the panel control unit 11 may be configured to identify the terminal device 20 that is undergoing the installation setting process and not permit communication from other terminal devices 20 during the installation setting process. In this case, since the photographing device 10 whose installation settings have not yet been completed cannot communicate with other terminal devices 20, erroneous photographing can be prevented, and the user can also It is possible to identify that the process has not been completed.

Further, when the installation setting information is transmitted while the installation state is "completed", the panel control unit 11 may notify that the installation state is "completed".
Furthermore, the panel control unit 11 may notify that the installation status has become "completed" when the installation status has become "completed", or may process the process while the installation status is "uncompleted". If the process is interrupted, a notification to that effect may be provided at the time of the interruption.
As a notification method, for example, a message may be displayed on the display unit 22 of the terminal device 20, or sound or light may be generated from the photographing device 10.

Therefore, the photographing device 10 whose installation settings have not yet been completed is unable to communicate with other instructions, and erroneous photographing before the installation settings are completed can be prevented. Further, by refusing other instructions until the installation settings are completed, the installation settings can be performed reliably. Further, the user can identify that the installation settings of the target photographing device 10 have not been completed.

Further, according to the present embodiment, when the panel control unit 11 determines that the installation settings are not completed, the panel control unit 11 determines whether the terminal device 20 that sent the information is the device that is currently performing the settings of the photographing device 10. If it is determined that the photographing device 10 is not currently being configured, wireless connection with the device is not permitted.
Therefore, the photographing device 10 whose installation settings have not yet been completed is unable to communicate with instructions from other devices, and erroneous photographing before the installation settings are completed can be prevented. Further, by rejecting instructions from other devices until the installation settings are completed, the installation settings can be performed reliably. Further, the user can identify that the installation settings of the target photographing device 10 have not been completed.
