First, the emergency control process will be described with reference to FIG. First, the emergency control unit 181 of the communication terminal 1 accepts an emergency operation by the user (S101). The emergency control unit 181 monitors the state of the first operation unit 13.

The emergency control unit 181 determines whether or not there has been an emergency operation by the user (S102). The emergency control unit 181 determines whether or not the pin-shaped first operation unit 13 has transitioned from the pushed state to the pulled out state.

When the emergency control unit 181 determines that an emergency operation has been performed (S102-Y), the emergency control unit 181 generates a buzzer sound via the voice output unit 16 (S103). The emergency control unit 181 continuously generates a buzzer sound until the first operation unit 13 transitions to the pushed state again. When the emergency control unit 181 determines that there is no emergency operation (S102-N), the emergency control unit 181 returns to S101 and continuously accepts the emergency operation. In addition, "Y" and "N" mean that the determination result is "Yes" and "No", respectively, and the same shall apply hereinafter.

Subsequently, the emergency control unit 181 activates the imaging unit 12 to capture an image (S104). The emergency control unit 181 causes an image to be captured regardless of the available capacity of the storage unit 11. The image captured by the emergency control unit 181 may be a still image or a moving image having a predetermined length.

Subsequently, the emergency control unit 181 determines whether or not the stored flag is set (S105). The stored flag is a flag set in the storage unit 11, and is set when the available capacity is equal to or less than the second threshold value after the image captured in response to the emergency operation is stored, as will be described later. It is a flag.

When the emergency control unit 181 determines that the stored flag is not set (S105-N), the emergency control unit 181 stores the captured image in the storage unit 11 (S106). In this way, the communication terminal 1 stores an image according to the stored flag, so that even if the available capacity is small, the communication terminal 1 stores at least one captured image, and when an emergency operation is performed a plurality of times, a large amount of images are stored. It is possible to prevent the image of the above from being stored and affecting the operation of the communication terminal 1. If it is determined that the stored flag is set (S105-Y), the emergency control process proceeds to S107.

Subsequently, the emergency control unit 181 transmits the captured image and the emergency message to the destination of the administrator (S107). The emergency control unit 181 refers to the destination table T1 and acquires the administrator's telephone number or e-mail address as the destination. Subsequently, the emergency control unit 181 transmits the e-mail containing the emergency message or the SMS (Short Message Service) to which the captured image is attached to the acquired destination.

Subsequently, the emergency control unit 181 determines whether or not the available capacity is equal to or less than the second threshold value (S108), and if it determines that the available capacity is equal to or less than the second threshold value (S108-Y), sets the stored flag. (S109), and the series of processes is completed.

Subsequently, the home screen processing will be described with reference to FIG. First, the display processing unit 182 displays the home screen 500 (S201). For example, the display processing unit 182 displays the home screen 500 on the display unit 15 in response to the fact that the power of the communication terminal 1 is turned on and the communication terminal 1 is activated, or the user presses the physical button 142.

Subsequently, the display processing unit 182 accepts an operation on the second operation unit 14 by the user (S202).

When there is an operation by the user, the display processing unit 182 determines whether or not the operation is a camera activation operation (S203). When it is determined that the operation is to start the camera (S203-Y), the camera screen display process is executed (S204). Details of the camera screen display process will be described later.

When the display processing unit 182 determines that the operation by the user is not a camera activation operation (S203-N), the display processing unit 182 determines whether or not the operation is a mail activation operation (S205). When it is determined that the operation is a mail activation operation (S205-Y), the mail screen display process is executed (S207). The details of the mail screen display process will be described later.

When it is determined that the operation by the user is not a mail activation operation (S205-N), the process corresponding to the operation is executed (S206). The process according to the operation is, for example, a process of starting the contact application in response to the operation of selecting the contact activation object 503. After the processing of S204, S206 or S207 is executed, the display processing unit 182 displays the home screen again (S201).

FIG. 10 is a flow chart showing an example of the flow of camera screen display processing. The camera screen display process is executed in S204 of the home screen process.

First, in response to the display processing unit 182 accepting the camera activation operation, the imaging processing unit 183 activates the imaging unit and displays the camera screen 600 on the display unit 15 (S301).

Subsequently, the capacity acquisition unit 185 acquires the available capacity when the camera screen 600 is displayed (S302).

When the available capacity is equal to or less than the second threshold value (S303-Y), the notification transmission unit 186 transmits the second notification message to the destination of the administrator (S304). The notification transmission unit 186 refers to the contact table T1 and acquires a telephone number or an e-mail address in which the administrator flag is set as a transmission destination. Subsequently, the notification transmission unit 186 determines whether or not the notification flag is set in the acquired transmission destination (that is, whether or not “notification is present”). When it is determined that the notification flag is set, the notification transmission unit 186 transmits the second notification message to the acquired destination via the communication unit 17. If it is determined that the notification flag is not set, the notification transmission unit 186 does not transmit the second notification message.

Subsequently, the control unit 187 displays a second warning message on the display unit 15 (S305). The control unit 187 superimposes the second warning message 621 and the second confirmation button 622 on the camera screen 600 to display the camera screen 620. The processes of S304 and S305 may be executed at the same time, or the process of S304 may be executed after the process of S305.

Subsequently, the control unit 187 instructs the image pickup processing unit 183 to end the display of the camera screen 600 (S306), and ends the camera screen display processing. The control unit 187 erases the second warning message 621 and the second confirmation button 622 in response to the operation of selecting the second confirmation button 622 by the user, and instructs the image pickup processing unit 183 to end the display of the camera screen 600. To do.

When the available capacity is equal to or less than the first threshold value and larger than the second threshold value (S303-N, S307-Y), the notification transmission unit 186 determines whether or not the notified flag is set (S308). .. The notified flag is a flag set when the first notification message is transmitted after the available capacity becomes equal to or less than the first threshold value.

When it is determined that the notified flag is not set (S308-N), the notification transmitting unit 186 transmits the first notification message to the destination of the administrator (S309). Like the second notification message, the first notification message is transmitted when the notification flag is set to the administrator.

Subsequently, the control unit 187 displays the first warning message on the display unit 15 (S310). The first warning message 611 and the first confirmation button 612 are superimposed on the camera screen 600 to display the camera screen 610. The processes of S309 and S310 may be executed at the same time, or the process of S309 may be executed after the process of S310.

After S310, or when the available capacity is larger than the first threshold value (S307-N) or when it is determined that the notified flag is set (S308-Y), the imaging process is executed (S311). The camera screen display process ends. The details of the imaging process will be described later.

In the camera screen display process, the notification transmission unit 186 may transmit the first notification message regardless of whether or not the notification flag is set. In this case, S308 is not executed, and S309 and S310 are executed when the available capacity when the camera screen 600 is displayed is equal to or less than the first threshold value (S307-Y). By doing so, the communication terminal 1 can more strongly urge the user or the administrator to manage the capacity of the storage device, and can secure the capacity of the storage device. The processes of S309 and S310 may be executed simultaneously or in any order.

FIG. 11 is a flow chart showing an example of the flow of the imaging process. The imaging process is executed in S311 of the camera activation process. When the imaging process is started, the camera screen 600 is displayed on the display unit 15.

First, the capacity acquisition unit 185 acquires the available capacity after the camera screen 600 is displayed (S401).

The control unit 187 sets the image pickup prohibition flag when the acquired available capacity is equal to or less than the second threshold value (S402-Y) (S403). The image pickup prohibition flag is a flag set when the available capacity becomes equal to or less than the second threshold value after the camera screen 600 is displayed.

After S403, or when the available capacity is larger than the second threshold value (S402-N), the image pickup processing unit 183 accepts an operation on the second operation unit 14 by the user (S404). The image pickup processing unit 183 accepts either an image pickup operation by the user or an end operation for ending the display of the camera screen 600. The image pickup processing unit 183 may accept other operations such as an operation of selecting the mode change object 603.

When the image pickup processing unit 183 receives the image pickup operation (S405-Y), the image pickup processing unit 183 captures an image and stores the captured image in the storage unit 11 (S406). When the image pickup processing unit 183 accepts an operation other than the image pickup operation (S405-N), that is, when the end operation is accepted, the display of the camera screen 600 ends and the image pickup process ends. When the image pickup processing unit 183 receives an operation different from the image pickup operation and the end operation, the image pickup processing unit 183 may execute the process corresponding to the operation.

Subsequently, the control unit 187 determines whether or not the imaging prohibition flag is set (S407). When the control unit 187 determines that the image pickup prohibition flag is not set (S407-N), the control unit 187 returns to S401.

When the control unit 187 determines that the image pickup prohibition flag is set (S407-Y), the control unit 187 displays a second warning message (S408), and ends the image pickup process. The control unit 187 superimposes the second warning message 621 and the second confirmation button 622 on the camera screen 600 to display the camera screen 620. The control unit 187 erases the second warning message 621 and the second confirmation button 622 in response to the operation of selecting the second confirmation button 622, and instructs the image pickup processing unit 183 to end the display of the camera screen 600.

FIG. 12 is a flow chart showing an example of the flow of the mail screen display process. The mail screen display process is executed in S207 of the home screen process.

First, the mail processing unit 184 displays the mail screen 700 (S501).

Subsequently, the capacity acquisition unit 185 acquires the available capacity when the mail screen 700 is displayed (S502).

When the acquired available capacity is equal to or less than the second threshold value (S503-Y), the notification transmission unit 186 transmits the second notification message to the destination of the administrator (S504), as in S304 of FIG. ..

Subsequently, the control unit 187 displays a second warning message on the display unit 15 (S505). The control unit 187 superimposes the second warning message 721 and the second confirmation button 722 on the mail screen 700 to display the mail screen 720. The processes of S504 and S505 may be executed at the same time, and the process of S504 may be executed after the process of S505.

When the available capacity is equal to or less than the first threshold value and larger than the second threshold value (S503-N, S506-Y), the notification transmission unit 186 determines whether or not the notified flag is set (S507).

When the notification transmission unit 186 determines that the notification flag is not set (S507-N), the notification transmission unit 186 transmits the first notification message (S508) in the same manner as in S308 of FIG.

Subsequently, the control unit 187 displays the first warning message on the display unit 15 (S509). The control unit 187 superimposes the first warning message 711 and the first confirmation button 712 on the mail screen 700 to display the mail screen 710. The processes of S508 and S509 may be executed at the same time, or the process of S508 may be executed after the process of S509.

After S505 or S509, or when the acquired available capacity is larger than the first threshold value (S506-N), the mail processing unit 184 accepts an operation on the second operation unit 14 by the user (S510). The mail processing unit 184 accepts a screen transition operation by the user or an end operation for ending the display of the mail screen 700. The screen transition operation is an operation of selecting the thread display object 701 on the mail screen 700 or an operation of selecting the back button 731 on the thread screen 730.

When the mail processing unit 184 accepts the screen transition operation (S511-Y), the mail processing unit 184 executes the screen transition process (S512) and returns to S510. The details of the screen transition process will be described later.

When the received operation is not a transition operation (S511-N), that is, the end operation, the mail processing unit 184 ends the display of the mail screen 700 or the thread screen 730, and ends the mail screen display process.

FIG. 13 is a flow chart showing an example of the flow of screen transition processing. The screen transition process is executed in S512 of the mail screen display process.

First, the mail processing unit 184 determines whether or not the screen transition operation is a transition operation to the thread screen 730 (S601). The mail processing unit 184 determines that the screen transition operation is a transition operation to the thread screen 730 when the screen transition operation received in S510 of the mail screen display process is an operation of selecting the thread display object 701 on the mail screen 700. judge. When the received screen transition operation is an operation of selecting the back button 731 on the thread screen 730, the mail processing unit 184 does not display the screen transition operation on the thread screen 730, that is, the transition operation to the mail screen 700. Is determined to be.

Subsequently, the mail processing unit 184 displays the thread screen 730 (S602) when the screen transition operation is the transition operation to the thread screen 730 (S601-Y). The mail processing unit 184 displays the thread screen 730 corresponding to the selected thread display object 701.

Subsequently, the capacity acquisition unit 185 acquires the available capacity when the thread screen 730 is displayed (S603).

When the available capacity is equal to or less than the second threshold value (S604-Y), the control unit 187 displays a second warning message (S605). The control unit 187 superimposes and displays the second warning message and the second confirmation button on the thread screen 730.

Subsequently, the control unit 187 limits the transmission of the mail (S606) and ends the screen transition process. The control unit 187 limits the transmission of mail by the user on the thread screen 730 by displaying the send button 734 on the thread screen 730 on the mail processing unit 184 in a manner in which the transmission button 734 cannot be selected.

When the available capacity is larger than the second threshold value (S604-N), the screen transition process ends.

The mail processing unit 184 displays the mail screen 700 when the screen transition operation is not the transition operation to the thread screen 730 (S601-N), that is, when the screen transition operation is the transition operation to the mail screen 700 (S607). ).

Subsequently, the capacity acquisition unit 185 acquires the available capacity when the mail screen 700 is displayed (S608).

When the available capacity is equal to or less than the second threshold value (S609-Y), the control unit 187 displays the second warning message (S610) and ends the screen transition process. The control unit 187 displays the mail screen 720 by superimposing the second warning message and the second confirmation button on the mail screen 700.

When the available capacity is larger than the second threshold value (S609-N), the screen transition process ends.

The available capacity when the mail screen 700 acquired in S501 of the mail screen display process is displayed may be used without acquiring the available capacity in S603 and S608.

As described above, when the available capacity when the camera screen 600 is displayed is equal to or less than the second threshold value, which is a value larger than the capacity required for storing an image, the communication terminal 1 has a camera screen. Instructs the end of the display of 600. By doing so, the communication terminal 1 can appropriately secure the capacity of the storage device required in an emergency.

Further, when the available capacity when the camera screen 600 is displayed is equal to or less than the first threshold value or the second threshold value, the communication terminal 1 displays the first warning message or the second warning message on the display unit 15. By doing so, the communication terminal 1 urges the user to secure the available capacity, and makes it possible to appropriately secure the capacity of the storage device.

Further, when the available capacity of the communication terminal 1 becomes equal to or less than the second threshold value after the camera screen 600 is displayed, an image is captured according to the imaging operation by the user, and the second notification is performed after the captured image is stored. A message is sent to instruct the end of the display of the camera screen 600. By doing so, the communication terminal 1 can appropriately manage the capacity of the storage device without impairing the user experience of the user who has performed the camera activation operation in order to take a picture.

Further, when the available capacity when the mail screen 700 or the thread screen 730 is displayed is equal to or less than the second threshold value, the communication terminal 1 limits the transmission of mail based on the operation on these screens by the user. By doing so, the communication terminal 1 can appropriately secure the capacity of the storage device required in an emergency.

In the above description, the capacity acquisition unit 185 has acquired the available capacity when the screens are displayed after the various screens are displayed, but the present invention is not limited to this. For example, the capacity acquisition unit 185 acquires the available capacity after the operation for displaying various screens by the user is accepted and before those screens are displayed, and this can be used when the various screens are displayed. It may be a capacity. Further, the capacity acquisition unit 185 may periodically acquire the available capacity, and the latest acquired available capacity when various screens are displayed may be used as the available capacity when those screens are displayed. ..

(Modification example 1)
In the above description, the imaging unit 12 is activated in the still image imaging mode in response to the camera activation operation, and the imaging mode is changed to the moving image imaging mode by the operation on the mode change object 603. However, the imaging unit 12 may be activated in the moving image imaging mode or the still image imaging mode according to the user's selection. Further, in this case, if the available capacity is equal to or less than the second threshold value, the imaging unit 12 may be activated in the still image imaging mode.

In this case, the imaging mode determination process is performed before S301 of the camera screen display process of FIG. FIG. 14 is a flow chart showing an example of the flow of the imaging mode determination process.

First, the capacity acquisition unit 185 acquires the available capacity when the camera activation operation is performed (S701). Subsequently, when the acquired available capacity is equal to or less than the first threshold value (S702-Y), the control unit 187 instructs the image pickup processing unit 183 to start the image pickup unit 12 in the still image capture mode (S703). , Ends the imaging mode determination process.

When the acquired available capacity is larger than the first threshold value (S702-N), the control unit 187 activates the imaging unit 12 in the still image imaging mode or the moving image imaging mode according to the user's selection. 183 is instructed to end the imaging mode determination process. That is, when the user selects the still image imaging mode (S704-Y), the control unit 187 instructs the imaging processing unit 183 to start the imaging unit 12 in the still image imaging mode (S703). Further, when the user selects the moving image imaging mode (S704-N), the control unit 187 instructs the imaging processing unit 183 to start the imaging unit 12 in the moving image imaging mode (S705).

The control unit 187 may accept in advance the user's selection as to which imaging mode the imaging unit 12 is activated before the camera activation operation is performed. For example, the control unit 187 accepts the designation of the image pickup mode at the time of starting the image pickup unit 12 on a setting screen (not shown). Further, the control unit 187 may instruct the image pickup unit 12 to start in the image pickup mode by selecting the image pickup mode when the display of the camera screen 600 is finished immediately before by the user.

By doing so, the communication terminal 1 limits the imaging of the moving image, which requires a large storage capacity, while preventing the user from impairing the user experience by smoothly starting the imaging of the still image. This makes it possible to properly secure the capacity of the storage device.

(Modification 2)
In the above description, the imaging time 634 is displayed on the camera screen 630 corresponding to the moving image imaging mode, but in addition to or instead of this, the imaging possible time 635 may be displayed.

FIG. 15 is a diagram showing an example of a camera screen 640 including an imaging possible time 635 displayed on the display unit 15. The camera screen 640 is displayed when the available capacity when the camera screen 630 corresponding to the moving image imaging mode is displayed is equal to or less than the first threshold value and larger than the second threshold value.

The imageable time 635 is a time during which a moving image can be captured, and is calculated based on the difference between the currently available capacity and the second threshold value, the resolution of the moving image, and the like. The user selects the imaging start object 632 and imaging is started, and as the imaging time 634 increases, the imaging possible time 635 decreases.

FIG. 16 is a flow chart showing an example of the flow of the imageable time display process. The image capture possible time display process is executed in response to the operation of selecting the mode change object 603 on the camera screen 600.

First, the capacity acquisition unit 185 acquires the available capacity when the mode change object is selected (S801). When the available capacity is larger than the first threshold value (S802-N), the control unit 187 ends the imaging available time display process.

When the available capacity is equal to or less than the first threshold value (S802-Y), the control unit 187 acquires the imageable time (S803). The control unit 187 calculates the difference between the available capacity and the second threshold value. Subsequently, the control unit 187 acquires the imageable time by dividing the calculated difference by the storage capacity per unit time of the moving image. The storage capacity per unit time is a preset approximate value.

Subsequently, the control unit 187 instructs the image pickup processing unit 183 to display the camera screen 640 including the calculated image pickup possible time (S804), and ends the image pickup possible time display process. The calculation of the imageable time may be performed only once when the mode change object 603 is selected, and is repeated periodically or irregularly while the camera screen 640 is displayed, and the imageable time 635 is updated. You may do so.

By doing so, the communication terminal 1 indicates to the user in advance the time during which the moving image can be captured, thereby appropriately securing the capacity of the storage device while preventing the user experience from being impaired.

It will be appreciated by those skilled in the art that various changes, substitutions and modifications can be made to this without departing from the spirit and scope of the invention. For example, the above-mentioned processing of each part may be executed in an appropriately different order within the scope of the present invention. Further, the above-described embodiments and modifications may be carried out in appropriate combinations within the scope of the present invention.
