The display / input unit 25 is provided so as to cover the front surface of the casing of the mobile terminal 20, and the display surface 22 also serves as an operation surface. When the display surface 22 is touched with the user's finger, the display / input unit 25 outputs a detection signal indicating that the touch operation has been performed and the touch position based on, for example, a change in the capacitance of the touch portion. .

The mobile terminal 20 activates an application program (hereinafter simply referred to as an application) associated with the icon 21 displayed on the display surface 22 of the display / input unit 25, thereby enabling a telephone function, a mail function, and browsing. Demonstrate functions realized by each application, such as functions and camera functions. In addition, the display content of the display surface 22 illustrated in FIG. 1A is an example of a so-called home screen. The camera 27 in FIG. 1B is used as a shooting camera when the mobile terminal 20 performs a camera function.
The camera 26 may be used when performing the camera function.

FIG. 2 is a block diagram illustrating the main configuration of the mobile terminal 20 of FIG. In FIG. 2, the mobile terminal 20 includes a display / input unit 25, a control unit 30, a camera 26, a camera 27, a communication unit 28, and a microphone 29.

<Display / input section>
The display / input unit 25 includes a display surface 22 and a position detection unit 23. As described above, the display surface 22 also serves as an operation surface. The position detection unit 23 includes a position detection signal indicating a contact position by a finger and display information (information indicating where and what is displayed on the display surface 22 of the display / input unit 25) of the display control unit 33. Based on this, an object (icon 21 or the like) on the screen of the display / input unit 25 is specified.

<Control unit>
The control unit 30 includes a program execution unit 32, a display control unit 33, a communication control unit 34, and a nonvolatile memory 35, and controls the operation of each unit in the mobile terminal 20. The program execution unit 32 executes a basic program called an operation system (OS), and then reads and executes an application running on the OS from the nonvolatile memory 35. Note that reading and executing an application from the nonvolatile memory 35 may be simply referred to as starting the application.

The program execution unit 32 normally executes an application associated with the icon 21 specified by the position detection unit 23 of the display / input unit 25. When the program execution unit 32 executes the camera application, the

camera

26 or 27 is activated to exhibit the photographing function. The user can activate any application corresponding to the icon 21 displayed on the display surface 22 of the display / input unit 25.

The display control unit 33 displays an image, text, icon 21 and the like on the display surface 22 of the display / input unit 25. The communication control unit 34 controls communication with an external device performed through the communication unit 28. The nonvolatile memory 35 stores the OS, applications, and necessary data. The user can add or delete any application that operates on the OS to the nonvolatile memory 35.

<Communication Department>
The communication unit 28 performs wireless communication in response to an instruction from the communication control unit 34. The communication unit 28 is configured to be able to communicate via a wireless LAN access point (not shown) and communicate via a mobile phone network (not shown).

<Explanation when passcode input is set>
The portable terminal 20 has a function (lock function) that requests the user to input a passcode for the purpose of preventing unauthorized access. When the lock function of the mobile terminal 20 is set to be effective, that is, when the setting for requesting the passcode is performed, for example, immediately after the power-on operation of the mobile terminal 20 or the return operation from the sleep state is performed. The portable terminal 20 is in a locked state (hereinafter referred to as a locked state). The locked state refers to a state in which access to data of the mobile terminal 20 and use of applications / functions are restricted except for a part until unlocking is performed. In addition, the locked state includes a state in which operations on the display surface 22 of the portable terminal 20 are restricted except for a part of operations until unlocking is performed. By performing an appropriate unlocking operation, the locked state of the mobile terminal 20 is released, and the data of the mobile terminal 20 can be accessed and applications and functions can be used. Note that the input of the passcode as an unlocking operation is an example, and a specific pattern may be input.

In the present embodiment, when the setting for requesting the passcode is performed at the time of power-on operation of the mobile terminal 20 or the return operation from the sleep state, the passcode is not input (that is, without unlocking). ) Enable the camera function. That is, the mobile terminal 20 can be released in a state where the camera application is activated without unlocking. It should be noted that on / off setting switching of a function that requires the input of a passcode during a power-on operation or a return operation from a sleep state is performed by a setting application for setting the mobile terminal 20. The setting application is associated with, for example, the setting icon 21B (FIG. 1 (a)).

The mobile terminal 20 displays both the passcode input display 41 and the release icon 42 on the display surface 22 of the display / input unit 25 as illustrated in FIG. The mobile terminal 20 on which the display shown in FIG. 3 is performed can accept both an unlock operation and a release operation.

As shown in FIG. 6, instead of displaying the passcode input display 41 on the display surface 22 of the display / input unit 25, a call icon 43 for displaying the passcode input display 41 is displayed. Also good. In this case, the passcode input display 41 is not displayed on the display surface 22 immediately after the power-on operation of the mobile terminal 20 or the return operation from the sleep state. When the user taps or slides (flicks) the call icon 43 with a finger, for example, the passcode input display 41 is displayed on the display surface 22. In FIG. 6, both a call icon 43 and a release icon 42 for displaying a passcode input display 41 are displayed on the display surface 22 of the display / input unit 25 of the mobile terminal 20. As a result, the user can perform both an unlock operation for releasing the lock of the portable terminal 20 by displaying the passcode input display 41 and a release operation.

In FIG. 3, a passcode input display 41 and a release icon 42 are displayed over the live view image. In FIG. 6, a call icon 43 and a release icon 42 are displayed over the live view image. The live view image refers to a monitor image that is repeatedly imaged by the camera 27 at a predetermined interval (for example, 30 frames / second) before a shooting instruction (release operation).

When the release icon 42 is tapped before the passcode is input by the user or during the passcode input by the user, the mobile terminal 20 immediately performs a shooting process. That is, the mobile terminal 20 does not require a user operation for activating a camera application, and automatically activates the camera application to be in a shooting standby state. Here, the tap operation on the release icon 42 is a release operation.

<Description of flowchart>
A flow of processing executed by the control unit 30 of the portable terminal 20 will be described with reference to a flowchart illustrated in FIG. When a power-on operation is performed on the mobile terminal 20, the control unit 30 performs a predetermined process when the power is turned on to start the program illustrated in FIG.

In step S10 of FIG. 4, the control unit 30 sends an instruction to the program execution unit 32, starts the OS stored in the nonvolatile memory 35, and proceeds to step S20. In step S20, the control unit 30 sends an instruction to the program execution unit 32, activates the lock application stored in the nonvolatile memory 35, and proceeds to step S30. When the lock application prompts the user to enter a passcode, and the pre-registered passcode is entered (unlock operation), the lock is released, and if the unlock operation is not performed properly It is a program that maintains the lock state. In the present embodiment, if the locked state is not released, the activation or execution of the application according to the user operation is prohibited.
In addition, you may comprise so that the input of a passcode may be calculated | required with respect to a user as a part of process by OS, without using a lock application.

In step S30, the control unit 30 sends an instruction to the program execution unit 32, activates the camera application stored in the nonvolatile memory 35, and proceeds to step S40. As a result, the camera 27 is activated based on the camera application, and the acquisition of the live view image is started. In addition, the camera function is enabled.

In step S40, the control unit 30 sends an instruction to the display control unit 33 to sequentially display the live view image on the display surface 22 of the display / input unit 25. A live view image including a person 45 and a person 46 in front of the user is displayed on the display surface 22 shown in FIG. The control unit 30 further sends an instruction to the display control unit 33 to display a passcode input display 41 (unlock screen) and a release icon 42 so as to overlap the live view image. The passcode input display 41 is based on the lock application, and the display of the release icon 42 is based on the camera application. The user can select whether to perform a lock release operation or a release operation.

As shown in FIG. 6, the control unit 30 sends an instruction to the display control unit 33, and a call icon 43 and a release for displaying an unlock screen (passcode input display 41) superimposed on the live view image. The icon 42 may be displayed. The call icon 43 is displayed based on the lock application or the OS, and the release icon 42 is displayed based on the camera application. The user can select whether to perform a lock release operation by displaying a lock release screen or to perform a release operation. The operation performed after the user operates the call icon 43 to display the passcode input display 41 (unlock screen) is the same as in FIG.

In step S45, the control unit 30 determines whether or not an operation by the user is detected within a predetermined time (for example, 5 seconds). If the operation is detected within a predetermined time, the control unit 30 makes a positive determination in step S45 and proceeds to step S50. If the predetermined time has elapsed without detecting an operation, the control unit 30 makes a negative determination in step S45 and proceeds to step S90. move on.

In step S50, the control unit 30 determines the detected operation. The control unit 30 determines that the unlocking operation has been performed when an appropriate passcode is input, and proceeds to step S60. Note that the program execution unit 32 ends the camera application when the process proceeds to step S60. As a result, the camera 27 stops and the display of the live view image ends. Note that instead of terminating the camera application, so-called background processing may be continued. Or you may continue as a foreground process so that it may mention later. On the other hand, when the release icon 42 is tapped, the control unit 30 determines that the release operation has been performed and proceeds to step S120. If the detected operation is neither the unlocking operation nor the release operation, the control unit 30 returns to step 45.

In step S <b> 60, the control unit 30 releases the lock state and sends an instruction to the display control unit 33 to display the home screen illustrated in FIG. 1A on the display surface 22 of the display / input unit 25.
In the case of proceeding from step S50 to step S60, if the foreground process is continued without terminating the camera application, the so-called wallpaper portion (excluding the icon 21 on the display surface 22) of the home screen illustrated in FIG. Live view image is displayed in (Part). Also, as one of the icons 21, a release icon 42 illustrated in FIGS. 3 and 6 is displayed.

In step S <b> 70, the control unit 30 sends an instruction to the program execution unit 32, accepts an operation for specifying the icon 21 by the user, and determines an application corresponding to the user operation (that is, the icon specified by the position detection unit 23 of the display / input unit 25). 21) is executed.

For example, when the application associated with the icon 21 is a camera application, the program execution unit 32 activates the camera application stored in the nonvolatile memory 35. As a result, the camera 27 is activated based on the camera application to start acquiring the live view image, and the release icon 42 is displayed on the display surface 22 of the display / input unit 25 together with the live view image based on the camera application. The

On the other hand, when the process proceeds from step S50 to step S60, when the foreground process is continued without terminating the camera application, the release icon 42 is displayed as one of the icons 21 on the display surface 22. In step S70, when the user operates the release icon 42 (tap operation), shooting processing is immediately performed.

In step S80, the control unit 30 determines whether or not a predetermined time (for example, 5 seconds) has passed without any operation. If the predetermined time has elapsed, the control unit 30 makes a positive determination in step S80 and proceeds to step S90. If the predetermined time has not elapsed, the control unit 30 makes a negative determination in step S80 and returns to step S70. When returning to step S70, the above process is repeated.

In step S90, the control unit 30 shifts to the sleep state and proceeds to step S100. When the mobile terminal 20 is not in the locked state, the mobile terminal 20 enters the locked state and shifts to the sleep state. The sleep state is a state of power saving such as display of the display / input unit 25 or termination of an application being executed. When the mobile terminal 20 is desired to be used, the original state (immediately before the transition to the sleep state is performed). A state that can be returned to (state).

In step S100, the control unit 30 determines whether a return operation has been performed. The control unit 30 determines that the return operation has been performed when a predetermined operation such as pressing a power button (not shown) is performed, for example, makes an affirmative determination in step S100, and returns to step S20. When it is not determined that the return operation has been performed, the control unit 30 makes a negative determination in step S100 and proceeds to step S110. When returning to step S20, if the lock application has already been activated, step S20 can be skipped. In addition, when the lock application is executed in the background (inactive) when returning to step S20, the process of starting the lock application (step S20) is the process of shifting the lock application to the foreground (step S20). Activation process). Similarly, after returning to step S20, if the camera application has already been activated, step S30 can be skipped. When the camera application is executed (inactive) in the background, the process for starting the camera application (step S30) is a process for shifting the camera application to the foreground (a process for activating). be able to.

In step S110, the control unit 30 determines whether a power-off operation has been performed. The control unit 30 determines that the power-off operation has been performed when a predetermined operation such as a long press of the power button is performed, and affirmatively determines step S110. Then, a predetermined process when the power is turned off is performed, and the process shown in FIG. When it is not determined that the power-off operation has been performed, the control unit 30 makes a negative determination in step S110 and returns to step S100. When returning to step S100, the sleep state is continued.

In step S120, the control unit 30 sends an instruction to the camera 27, causes the camera process to be performed based on the camera application, and returns to step S50. The acquired image data is stored in the nonvolatile memory 35.
In FIG. 4, the order of the process for starting the lock application (step S20) and the process for starting the camera application (step S30) is an example, and the order of the processes may be changed, and the processes are performed simultaneously. It may be broken.

According to the first embodiment described above, the following operational effects can be obtained.
(1) The program installed in the mobile terminal 20 includes a process for starting a lock application (S20) and a process for starting a camera application (S30), and a process for displaying a standby screen for a passcode input operation ( Since the program execution unit 32 executes the program before S40), an operation for activating the camera application (operation on the camera button in the prior art) can be made unnecessary. For this reason, it is possible to reduce the number of operations up to shooting before releasing the lock state, so that it is easy to make a photo opportunity.

(2) Since the program execution unit 32 is configured to execute the process (S40) for accepting a shooting instruction (release operation) to the camera 27 before the lock state is released, the shooting instruction to the camera 27 is instructed without unlocking. it can. For this reason, it becomes easy to make a photo opportunity.

(3) Since the program execution unit 32 executes the process (S40) of displaying the release icon 42 for accepting the shooting instruction together with the standby screen (input display 41) for the passcode input operation, the user The release operation (tap operation on the release icon 42) can be performed immediately before or during the passcode input.

Further, the program execution unit 32 is caused to execute a process (S40) of displaying a release icon 42 for receiving a shooting instruction together with a call icon 43 for displaying a standby screen (input display 41) for a passcode input operation. Thus, the user can immediately perform the release operation (tap operation on the release icon 42) in the locked state before the passcode input.

(4) Processing for displaying the live view image for monitoring acquired by the camera 27 based on the camera application before the shooting instruction, together with the standby screen (input display 41) for the input operation of the passcode and the release icon 42 ( Since the program execution unit 32 is caused to execute S40), the user can see a photo opportunity from the live view image before or during the passcode input.

Further, the program execution unit displays a process (S40) for displaying the monitor live view image acquired by the camera 27 based on the camera application before the shooting instruction, together with the call icon 43 and the release icon 42 on the unlock screen. 32, the user can see a photo opportunity from the live view image in the locked state before the passcode input.

(5) After returning from the sleep state, the program execution unit 32 executes a process for displaying the monitor live view image, the standby screen for the input operation of the passcode (input display 41), and the release icon 42. Therefore, the user can input the pass code immediately after returning from the sleep state.

In addition, since the program execution unit 32 executes processing for displaying the monitor live view image, the call icon 43, and the release icon 42 after returning from the sleep state, the user can easily return from the sleep state. You can enter a passcode.

Furthermore, the release operation can be performed immediately after returning from the sleep state. In other words, when it is not a situation where camera shooting is performed (when it is desired to use an application other than the camera application), the user can immediately perform a passcode input operation. When it is desired to use an application other than the camera application, it is troublesome for the user that a passcode input operation cannot be performed immediately. On the other hand, when it is desired to perform camera shooting, since the monitor live view image and the release icon 42 are displayed, the release operation can be performed immediately.

In the present embodiment, the description has been made on the assumption that a live view image for a monitor is displayed. However, the display of a live view image for a monitor is not necessarily required. When performing a release operation (so-called Noorok photography) without holding the camera and looking through the viewfinder, there is no need to display a live view image on the display surface 22.

(6) The program installed in the mobile terminal 20 is one of a passcode input operation for releasing the lock state and an operation for shooting instruction for the camera 27 before the lock state is released. Since the program execution unit 32 is caused to execute the process (S40) for displaying the screen for selecting (FIG. 3), the usability of the portable terminal 20 can be improved. In other words, when it is not a situation where camera shooting is performed (when it is desired to use an application other than the camera application), the user can immediately perform a passcode input operation. On the other hand, when it is desired to perform camera shooting, since the monitor live view image and the release icon 42 are displayed, the release operation can be performed immediately.

(7) When the mobile terminal 20 is unlocked by performing a passcode input operation (S50), the camera 27 is immediately terminated on the home screen of the mobile terminal 20 by continuing the foreground process without terminating the camera application. Release operation can be performed. That is, a live view image is displayed on a so-called wallpaper portion (a portion excluding the icon 21 on the display surface 22) of the home screen illustrated in FIG. 1A, and a release icon 42 is displayed as one of the icons 21 on the display surface 22. Since it is displayed, when the user operates the release icon 42 (tap operation), the shooting process is immediately performed.

The following modifications are also within the scope of the present invention, and one or a plurality of modifications can be combined with the above-described or later-described embodiments.
(Modification 1)
In the above description, in step S40 of FIG. 4, the live view image is displayed on substantially the entire display surface 22 of the display / input unit 25, and the passcode input display 41 and the release icon 42 are superimposed on the live view image. The display example (FIG. 3) has been described. Instead, the live view image may be displayed on a part of the display surface 22. In this case, for example, the live view image may be displayed in a window on a part of the display surface 22, or the live view image and the passcode input display 41 may be displayed side by side on the display surface 22. Thus, even in the first modification, it is possible to validate the camera function without unlocking.

(Modification 2)
In step S40 of FIG. 4, the passcode input display 41 and the release icon 42 may be displayed on the display surface 22 of the display / input unit 25, and the display of the live view image on the display surface 22 may be omitted. This is because the user can perform the release operation (tap the release icon 42) even when the live view image is not displayed. Thus, also in the second modification, it is possible to validate the camera function without unlocking.

(Modification 3)
In a case where the setting for requesting the passcode is not performed at the time of power-on operation of the mobile terminal 20 or the return operation from the sleep state, in step S40, the display surface 22 of the display / input unit 25 is displayed on the display surface 22 from the sleep state. You may make it display the display of the slide bar for instruct | indicating a return with the release icon 42. FIG. In this case, it is possible to accept both an unlock operation by a slide (flick) operation of the slide bar and a release operation by a tap operation of the release icon 42. That is, even in the third modification, the camera function can be validated without unlocking.

(Modification 4)
The mobile terminal 20 according to the above-described embodiment is not limited to a high-function mobile phone (so-called smartphone), and may be configured by a mobile device such as a digital camera or a tablet terminal. As shown in FIG. 5, for example, the program can be supplied to the digital camera, the tablet terminal, or the like from the personal computer 205 storing the program to the tablet terminal 20B or the like by infrared communication or short-range wireless communication.

The program may be supplied to the personal computer 205 by setting a storage medium 204 such as a CD-ROM storing the program in the personal computer 205 or by a method via the communication line 201 such as a network. You may load. When passing through the communication line 201, the program is stored in the storage device 203 of the server 202 connected to the communication line.

Also, the program can be directly transmitted to the tablet terminal 20B via a wireless LAN access point (not shown) connected to the communication line 201. Further, a storage medium 204B such as a memory card storing the program may be set in the tablet terminal 20B. Thus, the program can be supplied as various types of computer program products such as a data signal transmitted via a storage medium or a carrier wave.

(Modification 5)
In the above description, an example of operating the display / input unit 25 such as input of a pass code or input of a specific pattern has been described for the operation of unlocking the mobile terminal 20. The unlocking operation is not limited to the operation of the display / input unit 25 but may be a fingerprint authentication operation. FIG. 7 is a front view of the mobile terminal 20 according to the fifth modification. In FIG. 7, the mobile terminal 20 includes a fingerprint authentication sensor 60 in addition to the configuration illustrated in FIG. The display content of the display surface 22 illustrated in FIG. 1A is an example of a so-called home screen, but the display content of the display surface 22 illustrated in FIG. It is an example of the screen immediately after performing return operation from a state.

The fingerprint authentication operation is an operation of placing a finger on the fingerprint authentication sensor 60 in FIG. FIG. 8 is a block diagram illustrating the main configuration of the mobile terminal 20 of FIG. In FIG. 8, the mobile terminal 20 includes a fingerprint authentication sensor 60 in addition to the configuration illustrated in FIG. The fingerprint authentication sensor 60 reads the fingerprint of the finger placed on the fingerprint authentication sensor 60 in accordance with an instruction from the control unit 30 and sends the fingerprint data to the control unit 30. The control unit 30 releases the lock when the fingerprint read by the fingerprint authentication sensor 60 matches a registered fingerprint. By enabling the fingerprint authentication operation of the mobile terminal 20 in the state where the display shown in FIGS. 3 and 6 is performed, the lock can be released by the fingerprint authentication operation. At this time, the passcode input display 41 (FIG. 3) and the call icon 43 (FIG. 6) for displaying the passcode input display 41 may not be displayed on the display surface 22.

According to the modified example 5, by using the fingerprint authentication operation as the unlocking operation of the mobile terminal 20, the usability of the mobile terminal 20 can be improved. That is, when it is not a situation where camera shooting is performed (when it is desired to use an application other than the camera application), the user can immediately put a finger on the fingerprint authentication sensor 60 to release the lock state. On the other hand, when shooting with a camera is desired, the live view image for monitoring and the release icon 42 are displayed on the display surface 22, so the user can immediately perform the release operation.

(Modification 6)
In the above description, an example of operating the display / input unit 25 such as input of a pass code or input of a specific pattern has been described for the operation of unlocking the mobile terminal 20. The unlocking operation is not limited to the operation of the display / input unit 25 but may be a voice authentication operation. The voice authentication operation is an operation for inputting voice to the microphone 29 (FIG. 1 (a), FIG. 2) of the mobile terminal 20. The microphone 29 sends input voice (voice data) to the control unit 30. The control unit 30 releases the lock when the voice input from the microphone 29 matches the voice registered in advance. By enabling the voice authentication operation of the mobile terminal 20 in the state where the display shown in FIG. 3 or FIG. 6 is performed, the lock can be released by the voice authentication operation. At this time, the passcode input display 41 (FIG. 3) and the call icon 43 (FIG. 6) for displaying the passcode input display 41 may not be displayed on the display surface 22.

According to the modified example 6, by using the voice authentication operation as the unlocking operation of the mobile terminal 20, the usability of the mobile terminal 20 can be improved. That is, when it is not a situation where camera shooting is performed (when it is desired to use an application other than the camera application), the user can immediately release a sound to the microphone 29 to release the locked state. On the other hand, when shooting with a camera is desired, the live view image for monitoring and the release icon 42 are displayed on the display surface 22, so the user can immediately perform the release operation.

(Modification 7)
In the above description, an example of operating the display / input unit 25 such as tapping the release icon 42 for the release operation on the camera 27 of the mobile terminal 20 has been described. The release operation is not limited to the operation of the display / input unit 25, and may be a voice release operation (hereinafter referred to as a voice release operation). The voice release operation is an operation for inputting a shooting instruction to the microphone 29 (FIGS. 1A and 2) of the mobile terminal 20 with sound. The microphone 29 sends audio data to the control unit 30. The portable terminal 20 determines that the voice input from the microphone 29 matches the voice registered in advance as a voice release operation, and issues a shooting instruction to the camera 27. The voice release operation can be performed by enabling voice input and voice recognition of the mobile terminal 20 in a state where the display shown in FIGS. 3 and 6 is performed. At this time, the release icon 42 may not be displayed on the display surface 22.

According to the modified example 7, by using the voice release operation as the release operation for the camera 27, the usability of the mobile terminal 20 can be improved. In other words, in a situation where camera shooting is performed, the user can perform a release operation immediately without touching the release icon 42 by emitting a sound to the microphone 29. Further, even when the release icon 42 is not displayed on the display surface 22, the release operation can be performed.

(Second Embodiment)
The mobile terminal 20 according to the second embodiment is configured to be able to transmit information to an external device as an emergency call even if the locked state is not released. The emergency call is a function for making a call to an emergency call telephone number such as 110 or 118, for example, but may be a function for making a call to a telephone number of a family (for example, a parent) registered in advance. Furthermore, as long as it transmits information to an external device, it is not limited to a telephone but may be e-mail, instant messaging, short messaging, or the like. FIG. 9 is a block diagram illustrating the main configuration of the mobile terminal 20 according to the second embodiment. In FIG. 9, the mobile terminal 20 includes a position detection unit 70 in addition to the configuration illustrated in FIG. 2.

The position detection unit 70 acquires the position information of the mobile terminal 20 based on a transmission wave from a GPS satellite outdoors, and the position information of the mobile terminal 20 indoors based on a transmission wave generated by, for example, IMES (Indoor MEssaging System). obtain. The position information is sent from the position detection unit 70 to the control unit 30 in response to a request from the control unit 30.

FIG. 10 is a diagram illustrating a display screen of the display / input unit 25 of the mobile terminal 20. In FIG. 10, a call icon 43, a release icon 42, and an emergency icon 50 are displayed on the display surface 22 of the display / input unit 25. The call icon 43 and the release icon 42 are the same as the call icon 43 of FIG. 6 described in the first embodiment. The emergency icon 50 is an icon for performing an emergency operation in the locked state. For example, when the user taps the emergency icon 50 with a finger, the mobile terminal 20 accepts the emergency icon 50 as an emergency operation. The emergency operation is an operation required to cause the mobile terminal 20 to make an emergency call. In addition, after emergency operation is performed, the portable terminal 20 transmits an emergency call at various timings. In FIG. 10, the user can perform an emergency operation, an unlock operation performed by displaying the passcode input display 41, and a release operation.

When the release operation is performed following the emergency operation or together with the emergency operation, the mobile terminal 20 performs an emergency call for transmitting the captured image together with the position information. The transmission destination is, for example, an emergency call telephone number such as 110 or 118. Instead of calling by telephone number, an emergency call may be made by specifying a mail address.

Since steps S10 to S30 in FIG. 11 are the same as steps S10 to S30 in FIG. In step S40B, the control unit 30 sends an instruction to the display control unit 33 to sequentially display the live view image on the display surface 22 of the display / input unit 25 (FIG. 10). The control unit 30 further sends an instruction to the display control unit 33 to display the emergency icon 50, the call icon 43, and the release icon 42, respectively, superimposed on the live view image. The emergency icon 50 and the call icon 43 are displayed based on the lock application or OS, and the release icon 42 is displayed based on the camera application. The user can select whether to perform an emergency operation for an emergency call, display a lock release screen (passcode input display 41), perform a lock release operation, or perform a release operation.

The control unit 30 may display the lock release screen (passcode input display 41 (FIG. 3)) on the live view image without displaying the call icon 43 in step S40B.

In step S45 of FIG. 11, the control unit 30 determines whether or not an operation by the user is detected within a predetermined time (for example, 5 seconds). If the operation is detected within the predetermined time, the control unit 30 makes a positive determination in step S45 and proceeds to step S50B. If the predetermined time has elapsed without detecting the operation, the control unit 30 makes a negative determination in step S45 and proceeds to step S90. move on.

In step S50B, the control unit 30 determines the detected operation. The control unit 30 determines that the unlocking operation has been performed when an appropriate passcode is input on the unlock screen (passcode input display 41), and proceeds to step S60. Note that the program execution unit 32 ends the camera application when the process proceeds to step S60. As a result, the camera 27 stops and the display of the live view image ends. Note that instead of terminating the camera application, so-called background processing may be continued. Or you may continue as a foreground process mentioned above. On the other hand, when the emergency icon 50 is tapped, the control unit 30 determines that an emergency operation has been performed and proceeds to step S210.

Although not shown in FIG. 11, when the detected operation is a release operation, the control unit 30 performs a photographing process in the same manner as in FIG. When the detected operation is not any of the unlocking operation, the emergency operation, and the release operation, the control unit 30 returns to step S45.

Since steps S60 to S110 in FIG. 11 are the same as steps S60 to S110 in FIG.

Steps S210 to S250 correspond to emergency call processing. In step S210 that proceeds when an emergency operation is performed, the control unit 30 determines whether or not a release operation has been performed. For example, when the release icon 42 is tapped in a state where the operation on the emergency icon 50 is performed (for example, a state where the touch operation is continued), the control unit 30 makes a positive determination in step S210 and proceeds to step S220. As another example of the state in which the operation on the emergency icon 50 is performed, a state in which the emergency icon 50 is tapped to change the emergency icon 50 into a special mode that can be visually recognized by the user (hereinafter referred to as an active state). Also good. As a method of making the user a special aspect that can be visually recognized, there are methods such as changing the color of the emergency icon 50, emphasizing the outer frame of the emergency icon 50, and changing the stereoscopic effect of the emergency icon 50. By tapping the emergency icon 50 in the active state again, the emergency icon 50 returns to the original normal state. If the release icon 42 is tapped when the emergency icon 50 is in the active state, an affirmative determination is made in step S210 and the process proceeds to step S220.
When the release icon 42 is not tapped with the emergency icon 50 being operated, the control unit 30 makes a negative determination in step S210 and returns to step S50B. Note that if the release icon 42 is not tapped while the operation is performed on the emergency icon 50, that is, if the emergency icon 50 is operated for the purpose of an emergency call not accompanied by a photographing process, the control unit 30 performs step S220. The shooting process may be skipped and the process may proceed to step S230. In that case, only location information is transmitted at the time of an emergency call. Further, when the emergency icon 50 is operated for the purpose of an emergency call without imaging processing, the imaging processing in step S220 and the position information acquisition in step S230 may be skipped and the process may proceed to step S240. In that case, only an emergency call is made.

In step S220, the control unit 30 sends an instruction to the camera 27, causes the photographing process to be executed based on the camera application, and proceeds to step S230. The acquired image data is stored in the nonvolatile memory 35.

In step S230, the control unit 30 acquires position information from the position detection unit 70, and proceeds to step S240. Note that step S230 may be configured to be skipped. In that case, only the photographed image is transmitted at the time of emergency call. In step S240, the control unit 30 accepts a call operation. For example, the control unit 30 sends an instruction to the display control unit 33 to display a transmission screen (not shown) on the display surface 22 of the display / input unit 25 instead of the live view image. For example, the outgoing screen may be a 10-key display for making a call by inputting a telephone number, or a telephone number button for emergency call prepared in advance. The outgoing screen may be a display of an emergency call mail address book prepared in advance, for example, in addition to a mail creation screen for sending mail by inputting a mail address. Further, a menu screen for selecting a desired communication application from various communication applications may be displayed. Note that step S240 can be configured to be skipped by setting a communication application for making an emergency call and a communication destination (destination) in advance. In this case, if the control unit 30 determines in step S210 that the release operation has been performed, the transmission in step S250 is performed without any user operation.

In step S250, the control unit 30 sends an instruction to the communication control unit 34 to make a call. After establishing communication with the dial destination, the control unit 30 transmits the captured image acquired in step S220 together with the position information. When a call end operation is performed, control unit 30 ends the display of the outgoing call screen and returns to step S50B.
In addition, although the example which transmits a picked-up image and position information at the time of an emergency call was demonstrated, only a picked-up image may be transmitted and only position information may be transmitted.
According to the present embodiment, the program accepts an operation for receiving an operation for releasing the lock state of the terminal equipped with the camera and an operation for communicating with an external device different from the terminal in a state where the operation for releasing the lock state is possible. When a process and an operation for communicating with the external device are received, the computer is caused to execute the process of performing imaging with the camera.
In addition, according to the present embodiment, the program accepts an operation for releasing the lock state of the terminal including the camera, and an operation for communicating with an external device different from the terminal in a state where the operation for releasing the lock state is possible. And a process of transmitting an image captured by the camera to the external device when an operation for communicating with the external device is received.

According to the second embodiment described above, the following functions and effects can be obtained in addition to the same functions and effects as those of the first embodiment.
(1) The program installed in the portable terminal 20 displays the emergency icon 50 before releasing the locked state (S40B), and accepts an emergency operation using the emergency icon 50. Then, when a release operation is performed following the emergency operation, an emergency call is made to transmit the captured image together with the position information. As a result, it is possible to make a call to the emergency call phone number without unlocking, and to transmit the photographed image and the position information to the call destination (S250). For this reason, it is possible to make an emergency call appropriately in an imminent situation where there is no time to release the locked state.

(2) After returning from the sleep state, the program execution unit 32 executes a process (S40B) for displaying the monitor live view image, the emergency icon 50, the call icon 43, and the release icon 42. The user can perform an emergency operation immediately after returning from the sleep state. In addition, since the monitor live view image and the release icon 42 are displayed on the display surface 22, it is possible to perform a release operation at the time of emergency notification by looking at the live view image in the locked state.
In the present embodiment, the display of a live view image for a monitor has been described. However, the display of a live view image for a monitor is not necessarily essential. When performing so-called Noorok photography, it is not necessary to display a live view image on the display surface 22.

(Third embodiment)
The mobile terminal 20 according to the third embodiment is configured to be able to view content (for example, images) recorded in the nonvolatile memory 35 even if the locked state is not released.

FIG. 12 is a diagram illustrating a display screen of the display / input unit 25 of the mobile terminal 20 according to the third embodiment. In FIG. 12, an emergency icon 50, a call icon 43, a release icon 42, and an image browsing icon 55 are displayed on the display surface 22 of the display / input unit 25. The emergency icon 50, the call icon 43, and the release icon 42 are the same as the icons of FIG. 10 described in the second embodiment. Note that the emergency icon 50, the call icon 43, and the release icon 42 are not necessarily displayed on the display screen of the display / input unit 25 of the mobile terminal 20. When the call icon 43 is not displayed, the lock of the portable terminal 20 can be released by, for example, a fingerprint authentication operation or a voice authentication operation. Further, when the release icon is not displayed, the release can be performed by, for example, a voice release operation.

The image browsing icon 55 is an icon for performing an activation operation of the image browsing application in the locked state. For example, when the user taps the image browsing icon 55 with a finger, the mobile terminal 20 accepts it as an operation for starting an image browsing application. That is, in FIG. 12, the user can perform any of an image browsing application activation operation, an emergency operation, an unlock operation performed by displaying the passcode input display 41, and a release operation.

FIG. 13 is a diagram illustrating a list of thumbnail images displayed on the display surface 22 of the display / input unit 25. The portable terminal 20 activates the restricted image browsing application when the image browsing icon 55 in FIG. 12 is tapped in the locked state before the user enters the passcode or in the middle of the passcode input by the user. Then, as illustrated in FIG. 13, an emergency icon 50, a call icon 43, and a release icon 42 are displayed on the display surface 22 together with a thumbnail image list including thumbnail images A 1, A 2, A 5, A 7 and A 8. Note that it is not always necessary to display the emergency icon 50, the call icon 43, and the release icon 42 on the display surface 22 of the mobile terminal 20, and only a thumbnail image list including the thumbnail images A1, A2, A5, A7, and A8 is displayed. You may make it make it.

The thumbnail images A1, A2, A5, A7, and A8 are thumbnail images based on images that are set in advance by the user. The sharing setting is a setting that does not restrict browsing of content. The image set to be shared becomes a browsing target of content in the locked state, and can be browsed without unlocking (browsing is not limited). On the other hand, images that are not set for sharing are excluded from the content viewing target in the locked state, and cannot be browsed unless unlocked (browsing is restricted). Note that the above-described sharing setting is an example, and an image for restricting browsing of content may be designated. In this case, the designated image is excluded from the content browsing target in the locked state, and cannot be browsed unless unlocked (browsing is restricted). On the other hand, an image that is not designated becomes a browsing target of content in the locked state, and can be browsed without unlocking (browsing is not limited).
In this example, it is assumed that the images A1 to A10 are recorded in the nonvolatile memory 35, and among these, the images A1, A2, A5, A7, and A8 are set to be shared.

With the thumbnail image list displayed on the display surface 22, the mobile terminal 20 captures the face of the person (user or other person) observing the display surface 22 with the camera 26 ((a) of FIG. 1). A human face is detected from an image acquired by the camera 26, and the detected human face is included in the image A3, the image A4, the image A6, the image A9, and the image A10 that are not set to be shared. In this example, the face of the person detected from the image acquired by the camera 26 is regarded as the face of the person observing the display surface 22.

When the face of the person observing the display surface 22 is included in the image that is not set to be shared, the mobile terminal 20 adds a thumbnail image corresponding to the image including the face of the person to be observed to the thumbnail image list. Display. For example, when the face of the person observing the display surface 22 is included in the images A4 and A9 among the images A3, A4, A6, A9, and A10 that are not set to be shared, the mobile terminal 20 Displays thumbnail images corresponding to the images A4 and A9 in addition to the thumbnail image list.

FIG. 14 is a diagram illustrating a list of thumbnail images displayed on the display surface 22 of the display / input unit 25. Adding thumbnail images that can be viewed without releasing the lock state (that is, relaxing the viewing restrictions) allows the person observing the display surface 22 to view the image in which the person is reflected. Based on the idea of good. Note that the mobile terminal 20 determines whether or not the face of the person observing the display surface 22 is included in the images A1, A2, A5, A7, and A8 that are set to be shared. A thumbnail image corresponding to an image that does not include a face may be deleted from the thumbnail image list (FIG. 14) and displayed. By doing so, the thumbnail images included in the image list are only images showing the person, and convenience is improved.

<Description of flowchart>
A flow of processing executed by the control unit 30 of the mobile terminal 20 will be described with reference to a flowchart illustrated in FIG. When a power-on operation is performed on the mobile terminal 20, the control unit 30 performs a predetermined process when the power is turned on to start the program illustrated in FIG.

15 are the same as steps S10 to S30 in FIGS. 4 and 11, and thus description thereof is omitted. In step S40C, the control unit 30 sends an instruction to the display control unit 33 to sequentially display the live view image on the display surface 22 of the display / input unit 25 (FIG. 12). The control unit 30 further sends an instruction to the display control unit 33 to display the image browsing icon 55, the emergency icon 50, the calling icon 43, and the release icon 42 so as to be superimposed on the live view image. Note that the emergency icon 50, the call icon 43, and the release icon 42 are not necessarily displayed on the display surface 22 of the portable terminal 20, and only the image browsing icon 55 may be displayed. In addition, the display of the live view image is not always essential. Further, the activation of the camera application in step S30 is not essential, and when the camera application is not activated, the release icon 42 and the live view image are not displayed.

The display of the image browsing icon 55, the emergency icon 50, and the calling icon 43 is displayed based on the lock application or OS, and the release icon 42 is displayed based on the camera application. The user performs an activation operation of the image browsing application, performs an emergency operation for an emergency call, displays a lock release screen (passcode input display 41), or performs a lock release operation, or performs a release operation. You can choose whether to do.

The control unit 30 may display the unlock screen (passcode input display 41 (FIG. 3)) on the live view image without displaying the call icon 43 in step S40C.

In step S45, the control unit 30 determines whether or not an operation by the user is detected within a predetermined time (for example, 5 seconds). If the operation is detected within the predetermined time, the control unit 30 makes a positive determination in step S45 and proceeds to step S310. If the predetermined time has elapsed without detecting the operation, the control unit 30 makes a negative determination in step S45 and proceeds to step S340. move on.

In step S310, the control unit 30 determines whether or not the image browsing icon 55 has been operated by the user. When the image browsing icon 55 is tapped, the control unit 30 makes a positive determination in step S310 and proceeds to step S320. When the image browsing icon 55 is not tapped, the control unit 30 makes a negative determination in step S310 and proceeds to step S50C. .

In step S320, the control unit 30 sends an instruction to the program execution unit 32 to execute a browsing process, and proceeds to step S330. Details of the browsing process will be described later. In step S330, the control unit 30 determines whether or not a predetermined time (for example, 5 seconds) has passed without any operation. When the predetermined time has elapsed, the control unit 30 makes a positive determination in step S330, ends the browsing process, and proceeds to step S340. If the predetermined time has not elapsed, the control unit 30 makes a negative determination in step S330 and repeats the determination process.

In step S340, the control unit 30 shifts to the sleep state and proceeds to step S100. When the mobile terminal 20 is not in the locked state, the mobile terminal 20 enters the locked state and shifts to the sleep state.

Steps S100 to S110 in FIG. 15 are the same as steps S100 to S110 in FIGS.

In step S50C that proceeds when a negative determination is made in step S310, the control unit 30 determines whether or not the operation detected in step S45 is a lock release operation. The control unit 30 determines that the unlocking operation has been performed when an appropriate passcode is input on the unlock screen (passcode input display 41), and proceeds to step S60B. Note that the program execution unit 32 ends the camera application when the process proceeds to step S60B. As a result, the camera 27 stops and the display of the live view image ends. Note that instead of terminating the camera application, so-called background processing may be continued. Or you may continue as a foreground process mentioned above.

Although not shown in FIG. 15, when the detected operation is a release operation, the control unit 30 performs a photographing process in the same manner as in FIG. Further, when the detected operation is an emergency operation, the control unit 30 makes an emergency call in the same manner as in FIG. When the detected operation is not any of the unlocking operation, the emergency operation, and the release operation, the control unit 30 returns to step S45.

In step S60B, the control unit 30 releases the locked state and performs normal processing. In the normal process, for example, the home screen illustrated in FIG. 1A is displayed on the display surface 22 of the display / input unit 25, accepts an operation for specifying the icon 21 by the user, and executes an application corresponding to the user operation.
In step 60B, since normal processing is performed after the lock state is released, if the application to be executed is an image browsing application, the user can freely browse the content regardless of the sharing setting described above. Can do. For example, when images A1 to A10 are recorded in the nonvolatile memory 35, a thumbnail image list including the thumbnail images A1 to A10 is displayed on the display surface 22.

In step S80B, the control unit 30 determines whether or not a predetermined time (for example, 5 seconds) has passed without any operation. If the predetermined time has elapsed, the control unit 30 makes a positive determination in step S80B and proceeds to step S340. If the predetermined time has not elapsed, the control unit 30 makes a negative determination in step S80B and repeats the process.

<Browsing process>
Details of the browsing process (S320) will be described with reference to the flowchart of FIG. The control unit 30 that performs browsing processing activates the camera application, enables the camera function of the camera 26, and performs the following processing.

In step S321 in FIG. 16, the control unit 30 sends an instruction to the program execution unit 32 to start the restricted image browsing application, and browses and displays only the content (image in this example) that has been set in advance. Proceed to S322. The thumbnail images A1, A2, A5, A7, and A8 in the thumbnail image list illustrated in FIG. 13 all correspond to images that are set to be shared.

In step S322, the control unit 30 determines whether or not a face is detected from an image captured by the camera 26. Specifically, imaging is repeatedly performed by the camera 26 at a predetermined interval (for example, 30 frames / second). Thereby, when there is a person observing the display surface 22, the face of the person is imaged. The camera 26 sends the captured image to the control unit 30. The control unit 30 performs known face detection based on the image sent from the camera 26.

When the face is detected, the control unit 30 makes an affirmative determination in step S322 and proceeds to step S323. If the face is not detected, the control unit 30 makes a negative determination in step S322 and ends the process of FIG.

In step S323, the control unit 30 searches for the face of the detected person for the image A3, the image A4, the image A6, the image A9, and the image A10 that are not set to share, and the process proceeds to step S324.

In step S324, the control unit 30 determines whether there is an image including the detected human face. The control unit 30 makes an affirmative determination in step S324 and proceeds to step S325 when an image including the detected person's face is present in an image that is not set to be shared (that is, an image that is restricted for viewing). If there is no image including the detected person's face among the images that are not set to be shared (that is, images that are restricted for viewing), the control unit 30 makes a negative determination in step S324 and performs FIG. The process ends.

In step S325, the control unit 30 additionally displays a thumbnail image corresponding to the detected image including the face of the person in the thumbnail image list (FIG. 14), and ends the process of FIG. In FIG. 14, a thumbnail image A4 and a thumbnail image A9 are added as compared to FIG. The reason for the addition is that the face of the person observing the display surface 22 was shown in each of the images A4 and A9.
According to the present embodiment, the program receives a process for accepting an operation for releasing a lock state of a terminal including a camera, a process for accepting an operation for viewing an image in a state where the operation for releasing the lock state is possible, and the image When a browsing operation is received, the computer is caused to execute a process of displaying an image including a recognized face imaged by the camera.
In addition, according to the present embodiment, the program receives a process of accepting an operation for releasing a lock state of a terminal including a camera, a process of accepting an operation of browsing an image in a state where the operation of releasing the lock state is possible, When an operation for browsing an image is received, the computer is caused to execute a process of displaying an image whose browsing is not restricted and an image including a face imaged and recognized by the camera.
In addition, according to the present embodiment, the program receives a process of accepting an operation for releasing a lock state of a terminal including a camera, a process of accepting an operation of browsing an image in a state where the operation of releasing the lock state is possible, When an operation for browsing an image is received, the computer is caused to execute a process of displaying an image that is permitted to be browsed and an image including a face that has been captured and recognized by the camera.

According to the third embodiment described above, the following functions and effects can be obtained in addition to the functions and effects similar to those of the first embodiment and the second embodiment.
(1) The program installed in the mobile terminal 20 displays the image browsing icon 55 before releasing the locked state (S40C), and accepts an operation for starting an image browsing application using the image browsing icon 55. Then, thumbnail images based on images set in advance by the user are displayed as a thumbnail image list. This makes it possible to browse limited content (images in this example) without unlocking.

(2) When a face of a person observing the display surface 22 is photographed by the camera 26 and the face of the person photographed by the camera 26 is included in an image that is not set to be shared, the image including the face is included. The corresponding thumbnail image is displayed in addition to the thumbnail image list. Thereby, based on the idea that a person observing the display surface 22 may be allowed to view an image of the person, the viewing restriction can be appropriately relaxed without releasing the lock state. it can.

(3) Since the program execution unit 32 executes the process (S40C) for displaying the image browsing icon 55, the emergency icon 50, the call icon 43, and the release icon 42 after returning from the sleep state, the user Upon returning from the sleep state, it is possible to immediately start the image browsing application.
