Electric power is supplied from the supply source to each unit, and the portable terminal 1 is made operable.

  The display unit 12 is a monitor or the like, and displays document data, image data, and the like based on the control of the control unit 10. The operation unit 13 is an input device such as a touch panel or operation keys. The imaging unit 18 performs image processing on the image signal captured by the CCD camera 181 and displays it on the display unit 12.

  The voice control unit 14 converts the analog voice signal collected by the microphone 142 into a digital voice signal based on the control of the control unit 10. Further, when acquiring the digital audio signal, the audio control unit 14 converts the digital audio signal into an analog audio signal based on the control of the control unit 10 and outputs the analog audio signal as audio from the speaker 141.

  Based on the control of the control unit 10, the wireless communication unit 15 processes a reception signal received from the base station via the antenna 15 a to restore voice / audio data, image data, control data, and the like. When audio / audio data is obtained by restoration, it is transmitted to the audio control unit 14 and output from the speaker 141 in accordance with an instruction from the control unit 10, and when image data is obtained, a display is displayed via the display unit 12. 52 or recorded in the storage unit 16. Further, when the wireless communication unit 15 acquires the voice signal collected by the microphone 142, the character string input by the operation key 53 and various data stored in the storage unit 16 based on the control of the control unit 10, Is transmitted to the base station via the antenna 15a.

The storage unit 16 serves as a work area for the control unit 10 and the wireless communication unit 15 and can be realized by a RAM (Random Access Memory) or the like.
The information storage medium 17 (a computer readable medium) stores programs, data, and the like, and can be realized by a hard disk, a memory (Flash Memory, ROM: Read Only Memory), or the like. The information storage medium 17 stores a program for causing a computer to function as each unit of the present embodiment (a program for causing a computer to execute processing of each unit), a plurality of applications, and the like.

  The dictionary database 21 stores a fixed dictionary 211 and a user dictionary 212 as word dictionaries that the mobile terminal 1 has. The fixed dictionary 211 is a dictionary that the mobile terminal 1 has in advance. The user dictionary 212 is a dictionary that stores words registered by the user. The user dictionary 212 also stores conversion candidate display order information and the like so that words frequently used by the user are displayed at the top of the conversion candidates when a character string is input.

The data folder 22 stores character data input by the operation unit 13, image data captured by the imaging unit 18, audio data recorded by the microphone 142, and the like.
The backup folder 23 is a folder for temporarily storing images taken by the imaging unit 18 before saving them in the data folder 22.

  The control unit 10 is an arithmetic device that performs overall control of the mobile terminal 1 and performs various other arithmetic processing and control processing. The function of the control unit 10 can be realized by hardware such as various processors (CPU, DSP, etc.), ASIC (gate array, etc.), and programs. The control unit 10 performs various processes of the present embodiment based on a program (data) stored in the information storage medium 17.

The control unit 10 includes a lock function 101, an application activation function 103, a notification function 105, an application setting function 107, and a predictive conversion function 109.
The lock function 101 performs a setting to lock the function of the portable terminal 1 and invalidate the operation from the operation unit 13 by a lock setting operation from the operation unit set in advance. Further, the lock of the mobile terminal 1 is released by a lock release operation from the operation unit 13 set in advance. During the lock setting of the mobile terminal 1, the lock function 101 accepts an operation by validating only a specific operation (for example, unlock operation or memo key operation) from the operation unit 13.

  The application activation function 103 activates an application stored in the information storage medium 17. The notification function 105 generates various notifications to be displayed on the display unit 12, for example, a notification of free space in the data folder 22 or a warning notification when an invalid operation is performed while the mobile terminal 1 is locked. The application setting function 107 sets an application that can be activated when the mobile terminal 1 is locked by the lock function 101 from an application stored in the information storage medium 17. In the present embodiment, the startable applications set by the application setting function 107 during the lock setting of the mobile terminal 1 are a notepad, a shooting application, and a voice recorder application.

  The predictive conversion function 109 predicts a candidate for a phrase that is considered to be input by the user by referring to the user usage frequency from the user dictionary 212 from the character string to be converted input by the user, and the display unit 12 To display. For example, when the user inputs “wa” and “ta” in succession, the predictive conversion function 109 is a word that begins with “wata” and is frequently used by the user “me”, “cross”, “wataame” And the like are displayed on the display unit 12 as prediction candidates. Note that the predictive conversion function 109 disables the function when the lock function 101 is set to lock the mobile terminal 1.

  Next, the operation of the mobile terminal 1 having the above configuration will be described with reference to the flowchart of FIG. 2 and the screen display example of FIG.

  If the mobile terminal 1 is not locked (“No” in step S101), the mobile terminal 1 performs a normal operation by an operation from the user (step S103). On the other hand, when the lock function 101 locks the function of the portable terminal 1 by the user's operation using the operation unit 13 (“Yes” in step S101), the user presses the memo key of the operation unit 13 (step S101). The lock function 101 releases the lock of the mobile terminal 1 temporarily and within a certain range (step S106). Next, the display unit 12 displays a menu of a list of applications that can be activated during the lock setting set by the application setting function 107 (step S107). For example, as shown in FIG. 3A, a list of notepads, cameras (photographing applications), and voice recorders (voice recorder applications), which are applications set by the application setting function 107, is displayed as an “immediate memo menu”. 12 is displayed.

  When the user selects “Notepad” using the operation unit 13 from the “immediate memo menu” screen displayed on the display unit 12 (“Yes” in Step S109), the application activation function 103 is stored in the information storage medium 17. The stored memo pad application is activated and an input screen is displayed on the display unit 12 (step S110). FIG. 3B shows a screen display example when the memo pad is activated in step S110.

  Similarly, when “camera” is selected (“Yes” in step S111), the application activation function 103 activates a photographing application stored in the information storage medium 17, and operates the CCD camera 181 via the imaging unit 18. (Step S112). FIG. 3C shows a screen display example when the camera is activated in step S112. The shooting application may be a still image shooting or a moving image shooting.

  Similarly, when “voice recorder” is selected (“Yes” in step S113), the application activation function 103 activates the voice recorder application stored in the information storage medium 17, and operates the voice control unit 14 and the microphone 142. (Step S114). FIG. 3D shows a screen display example when the voice recorder is activated in step S114. At this time, the control unit 10 may display the recordable time with reference to the free space of the data folder 22.

  The memo pad data input in step S110, the image data photographed in step S112, and the voice data recorded in step S114 are stored in the data folder 22 (step S116).

  When the user selects none of the memo pad, camera, and voice recorder from the list displayed in the “immediate memo menu” and presses the “return” button in FIG. 3A (“No” in step S113), The lock function 101 locks the portable terminal 1 that has been unlocked temporarily and within a certain range in step S106, and invalidates the operation from the operation unit 13 (step S115).

  If the data folder 22 has little or no free space, the notification function 105 refers to the free space when each application is started in steps S110, S112, and S114, and generates a notification that the free space is low or not. It may be displayed on the display unit 12. For example, the notification function 105 refers to the free space of the data folder 22 when the notepad application is started in step S110, and if there is no free space, the display unit 12 displays “data folder is full” or the like. Also good. The same applies when the voice recorder application is activated in step S114.

  When the shooting application is started in step S112, the backup folder 23 may be referred to in addition to the data folder 22. The notification function 105 refers to the free capacity of the data folder 22 and refers to the free capacity of the backup folder 23 when there is no free capacity. If there is free space in the backup folder 23, the display unit 12 displays “captured image is stored in the backup folder”, and prompts the user to delete the data in the data folder 22. If there is no free space in the backup folder 23, the display unit 12 is displayed such as "The folder is full and cannot be shot".

  When the wireless communication unit 15 receives an incoming call when each application is started in steps S110, S112, and S114, the application is terminated and the incoming call is displayed on the display unit 12. At this time, for example, when the input is in the memo pad, the application is terminated after the input data until the incoming call is automatically saved. If the voice recorder is recording, the recorded data up to the incoming call is automatically saved and the application is terminated.

  In step S105, when the lock is set, a list of applications set by the application setting function 107 is displayed by a short press of the memo key by the user, and the top application in the application list is activated by pressing the memo key for a long time. May be. For example, when a “memo menu” when a memo key is pressed shortly and a list is displayed in the order of memo pad, camera, and voice recorder, the memo pad application may be activated once when the memo key is pressed long.

  By the way, an application selected from the “immediate memo menu” at the time of lock setting is restricted in its operation as compared with an application at normal operation which is not set to lock. This is because the lock function is originally set in order to give the mobile terminal 1 a security function, so that the security function of the mobile terminal 1 is maintained as much as possible. For example, when the lock is set, communication with other terminals is not performed, and functions related to communication are set not to be displayed on the display unit 12.

  FIG. 4 shows a screen display example when the memo pad is activated from the “immediate memo menu” when the lock is set (A) and when the memo pad is activated during the normal operation where the lock is not set (B). During normal operation (B), if the user presses the memo key while the standby screen (B-1) is displayed, a list of memo pads (B-2) is displayed. For example, if the user has a notepad No. 1 “Meeting time is 10:00” and press the “Edit” button. 1 editing screen (B-3) is displayed. On this editing screen (B-3), the user makes correction input of characters using the operation unit 13, quotes internal data such as the address book of the portable terminal 1 from the “submenu” button, etc. You can communicate with the terminal. Character input can be input using the predictive conversion function 109, and the predictive conversion function 109 displays candidates predicted from the input character string at the bottom of the display unit 12. For example, when the user inputs a character string “Aggregation time is” on the screen of (B-4), the predictive conversion function 109 refers to the dictionary database 21 and predicts that it will follow the character string from the user's usage frequency. In this example, “13:00”, “12:00”, “9 o'clock”, and “what time?” Are displayed as prediction candidates at the bottom of the screen of the display unit 12. The user selects from these prediction candidates or directly inputs characters.

  On the other hand, when the lock is set (A), when the user presses the memo key while the standby screen (A-1) is displayed, the “immediate memo menu” is activated, and the memo pad, which is the application set by the application setting function 107, A list of cameras and voice recorders is displayed (A-2). When the user selects “Notepad”, the Notepad application is activated and the input screen (A-3) is displayed. Here, when a memo pad is selected on the screen (A-2), a list of memo pads as shown in (B-2) is not displayed, and a memo pad input screen is displayed immediately. This is to prevent a person other than the user from browsing the memo pad registered in the mobile terminal 1 with a simple operation. It is assumed that the user inputs “Reserve DVD” on the input screen using the operation unit 13 (A-4). At this time, the predictive conversion function 109 cannot be used for character input. For example, if the prediction conversion function 109 is enabled, personal names and place names frequently input by the user are displayed in the prediction candidates, and personal information is known when a person other than the user inputs characters. Because there is a fear. In addition, only the “Save” button and the “Return” button are displayed in the memo pad activated when the lock is set (A). At the time of lock setting (A), only the input character string is stored, and quoting from internal data and communication to other terminals that can be used in normal operation (B) are not performed. Note that the memo pad data saved at the time of lock setting (A) is not registered and the upper memo pad No. (For example, notepad No. 3 in (B-2)) is automatically stored.

  Therefore, the operation of the memo pad at the time of lock setting (A) is merely input and storage in order to maintain security, and the function is limited more than at the time of normal setting (B), and the display screen is also different. .

  Similarly, FIG. 5 shows screen display examples when the camera is activated from the “immediate memo menu” at the time of lock setting (C) and when the camera is activated at the time of normal operation where lock is not set (D). During normal operation (D), when the user presses the camera start button while the standby screen (D-1) is displayed, the shooting screen (D-2) is displayed. On this shooting screen (D-2), the user switches the shooting size with the “size” button, or browses the shot images in the data folder 22 and sets the details of the shooting conditions from the “submenu” button. You can shoot with the “shoot” button. The captured image (D-3) is temporarily stored in the backup folder 23. The user can save this image in the data folder 22 by pressing the “Save” button, edit the image taken with the “Submenu” button, or send the image to another terminal with the “Mail” button. I can do it.

  On the other hand, when the lock is set (C), when the user presses the memo key while the standby screen (C-1) is displayed, the “immediate memo menu” is activated, and the memo pad, which is the application set by the application setting function 107, A list of cameras and voice recorders is displayed (C-2). When the user selects “camera”, the photographing application is activated and the photographing screen (C-3) is displayed. At this time, for example, (D-2) is displayed on the shooting screen (C-3) so that a person other than the user does not easily change the shooting conditions or browse the shot images in the data folder 22 without permission. The “submenu” button such as) is not displayed, and only the “shoot” button and the “return” button are displayed. The image (C-4) photographed on the photographing screen (C-3) is temporarily stored in the backup folder 23. The user saves this image in the data folder 22 by pressing the “Save” button. Also at this time, only the “Save” button and the “Return” button are displayed on the shooting screen of (C-4). When the lock is set (C), only the captured image is saved, and the image editing and communication to other terminals that can be used in the normal operation (D) are not performed.

  Therefore, the camera shooting operation at the time of the lock setting (C) is merely shooting and storage in order to maintain security, and the function is limited more than that at the time of the normal setting (D), and the display screen is also different. Yes. The operation of the voice recorder at the time of lock setting is the same as that of the camera photographing operation.

  Further, in order to distinguish between data stored in the data folder at the time of lock setting and data stored in the data folder at the time of normal operation, a flag may be attached to the data stored at the time of lock setting in the data list display. For example, in the notepad list screen of FIG. 6A, a notepad No. with a marker in the “lock” column. Reference numeral 3 denotes memo pad data stored at the time of lock setting. In addition, when an icon indicating an image thumbnail and audio data is displayed on the data folder list display screen of FIG. 6B, the data with the marker at the left end of the thumbnail or icon is the data stored at the time of lock setting. is there.

  In addition to the above-mentioned notepad, shooting application, and voice recorder application, applications set by the application setting function 107 include applications that do not require a communication function and can maintain a security function, such as a business card reader, calculator, electronic Each application such as dictionary and loupe may be set.

  As described above, according to the embodiment of the present invention, when the mobile terminal 1 is locked by the lock function 101, it is activated during the lock setting set by the application setting function 107 by a specific simple operation such as pressing a memo key. Possible applications can be launched. Therefore, if you set the application that can be activated during the lock setting, such as notepad, camera shooting, and recording, even if the mobile device is locked, for example, when you want to take a note immediately, start the notepad immediately It is possible to prevent troublesome unlocking operations and forgetting to take notes. In addition, the security function can be maintained as much as possible by restricting the function of the application started during the lock setting.

  As mentioned above, although embodiment of this invention was explained in full detail with reference to drawings, the specific structure is not restricted to this embodiment, The design change etc. of the range which does not deviate from the summary of this invention are included.
