However, the present invention can be applied to a public facility such as a museum or a museum, an exhibition hall, etc. having a photographing permission / prohibition area in addition to the factory. it can.
First, the outline of the present invention will be described with reference to FIGS.
As shown in FIG. 1, for example, an inspection of belongings is performed at the entrance of a factory, and when a person who enters has a mobile phone (including a mobile terminal), the mobile phone is deposited at a reception. Then, the factory mobile phone 1 is lent to the visitors.
A wireless LAN device 2 is installed in the factory, and access points AP (hereinafter also abbreviated as AP) to the wireless LAN are provided at a plurality of locations on the premises. It is connected to the server 3 via 4 or the like.

Camera shooting permission / camera shooting prohibition is set for each access point, the camera shooting permission access point group ID (group ID, for example, dd), and the camera shooting permission access point group ID (group ID, for example, ee). Are set to different values. This group ID is, for example, an IEEE 802.11b SSID.
As shown in FIGS. 2A and 2B, the cellular phone 1 that is lent to the visitors is a normal cellular phone provided with a display unit 1a, operation buttons 1b, a camera 1c, a memory 1d, a communication unit 1e, and the like. However, the camera permission means 1g is provided in the control unit 1f. For example, when the camera permission unit 1g is normally set to a camera shooting prohibited state and the ID of the access point group is camera shooting permission, the camera permission unit 1g sets the camera to shooting permission.
Further, as shown in FIG. 2A, the wireless local area LAN includes a plurality of communication units 2a provided in the camera photographing permission area, a plurality of communication units 2b provided in the camera photographing prohibited area, and a control unit 2c. The memory 2d is configured. The control unit 2c is provided with a transmission / reception suppression unit 2e. The transmission / reception suppression unit 2e determines whether or not the mobile phone to which an image is to be transmitted is in the camera photographing prohibition area from the ID of each access point, Transmission of image information via the communication unit 2b in the camera photographing prohibited area is suppressed.

That is, when a visitor with the mobile phone 1 lent at the reception is in the camera shooting permission area (for example, access point ID = dd), the camera 1c of the lent mobile phone 1 can shoot. Further, the captured image can be transmitted to the server 3 as, for example, a mail attachment file via the access point and the local wireless LAN 2.
If the image taken as described above is transferred to the server 3, the image stored in the server 3 can be transferred with the user's mobile phone even if the rented person returns the loaned mobile phone 1. It is also possible to receive.
As will be described later, when the present invention is applied to management of progress, etc., it is possible to grasp the progress of work from the image sent to the server 3 and manage the progress of work. Is possible.
If the image taken with the mobile phone 1 is transferred to the server and then deleted immediately, the image will not be accumulated in the mobile phone, and the user forgets to delete the image and then lends it. Sometimes it is possible to prevent the previous image from being seen.

On the other hand, when a visitor is in a camera shooting prohibition area (for example, access point ID = ee), shooting cannot be performed with the camera 1c of the lent mobile phone 1, and via the access point and the local wireless LAN 2 The image cannot be transmitted to the server 3.
If you are in the camera shooting prohibition area or the camera shooting permission area, you can use the mobile phone 1 to contact the outside by voice, and you can enter a phone number from the mobile phone to talk to the other party. it can. Further, it may be possible to send an email without an image. Further, the mobile phone 1 may be able to receive an email including an image sent from the outside.

FIG. 3 is a flowchart showing processing in the cellular phone and the local wireless LAN.
When the visitor enters the factory with the loaned mobile phone, the mobile phone searches for a wireless LAN access point and sets the SSID of the mobile phone (steps S1 and S2).
Next, it is determined whether the access point is in the camera shooting permission area. If the access point is not in the camera shooting permission area, the process returns to step S1 (step S3).
In the case of the camera shooting area, the mobile phone is set to the camera shooting permission mode (step S4).
Here, the image data taken by the attendant using the camera of the mobile phone is stored, and the telephone number is notified to transmit the image data (steps S5, S6, S7).
Then, data communication is performed, and image data captured by the camera is transmitted (steps S8 and S9).
On the other hand, in the wireless LAN device, it is determined whether the SSID of the mobile phone matches (step T1). If they match, when the telephone number is received, connection processing is performed with the telephone number and the data from the mobile phone is transferred to the telephone network. Transmit (steps T2, T3, T4).

Next, it is determined whether there is an attached file (step T5). If there is no attached file, the process goes to step S9. If there is an attached file, it is determined whether the identifier of the attached file is image data of the camera (step T6). And if it is an access point of camera photography permission, communication of the said image data is permitted and it communicates (step T7, T8, T9).
In the mobile phone, when the communication is completed, the image data captured by the camera is deleted (steps S10 and S11). Next, it is determined whether there is a next communication, and if there is, the process returns to step S5. If not, the camera photographing permission mode is canceled and the process returns to step S1.
In the above-described flow, the call processing in the case of being in the camera photographing permission area has been described. However, only a voice call may be allowed in the camera photographing prohibited area.

Next, an embodiment in which the present invention is applied to work progress management will be described.
For example, in the case of building construction, line installation work, machine installation work, robot installation or refurbishment in a factory by an outside contractor, the progress of the work as the contractor performing these work There is a request to manage. For example, if a video showing the progress of work is captured by a camera at each work site, the image information and the like are transmitted sequentially, received by a management server, for example, and displayed intensively, You can keep track of your progress online. In addition, in the case of work that needs to proceed simultaneously in each place, it can be grasped in real time with image information.
On the other hand, the factory wants to ban camera shooting because it allows the shooting at the work place, but if the camera is shot at other places, there is a problem such as leakage of trade secrets. However, it is impossible to always check the worker's behavior.
Therefore, a place where an outside contractor works in the factory is set as a camera shooting permission area as described above, and other places are set as a camera shooting prohibition area.
When the work progress status management is performed, the worker sequentially captures the work status with a camera based on a predetermined procedure, and this image is managed via the local wireless LAN as described above. Send to.
Based on information such as images sent from each work place, the management server gives an overview of the progress of work at each work place, contacts the workers as necessary, and supplies missing materials. Send to work site. By doing so, it is possible to manage the progress of work in the factory or the like.
