JP5901479B2 - Portable information terminal, its control method, and computer program for portable information terminal - Google Patents

Description

  The present invention relates to a portable information terminal, a method for controlling the portable information terminal, and a computer program for the portable information terminal. More specifically, the portable information terminal is moved from a locked state to an unlocked state by operating a lock release operator on a lock screen. The present invention relates to an improvement of a portable information terminal to be changed to.

  Generally, a portable information terminal equipped with a touch panel, for example, a mobile phone such as a smartphone or a tablet computer, shifts to a sleep state in which the touch panel is turned off to reduce power consumption if there is no user operation for a certain period of time. This sleep state is canceled by the user's sleep release operation, and a lock screen is displayed on the touch panel that has returned from the sleep state.

  On the lock screen, an unlock operation element such as a slide operation element is displayed. When the user operates the unlock operation element, the lock state is released and a program selection screen for selecting an application program is displayed. The By adopting such a configuration, if the sleep release operation and the lock release operation are not performed in order, the touch panel does not transition from the sleep state to the program selection screen, and the program selection screen is displayed against the user's will. Can be prevented.

  Such an unlocking operation is an operation that is repeated every time the user uses the portable information terminal. Therefore, if a process other than the unlocking can be executed based on the unlocking operation, the convenience of the user is improved. It is thought that it can be made. For example, a mobile terminal has been proposed in which two or more icons are displayed on a lock screen and any one of the icons can be selectively operated (for example, Patent Document 1).

  In the mobile terminal described in Patent Document 1, a lock icon Ri and a manner icon Mi are displayed on a lock screen. The lock icon Ri is an icon for releasing only the locked state, and the manner icon Mi is an icon for releasing the locked state and switching between the normal mode and the manner mode. For this reason, the user can switch the mode simultaneously with unlocking as necessary by selectively operating the icon.

  Here, recent portable information terminals have increased power consumption with higher functions and larger screens, and the driving time after the built-in battery is fully charged has become shorter. For this reason, it is important to reduce unnecessary power consumption and lengthen the time that can be used by one charge. Therefore, it is conceivable to execute the power saving process simultaneously with the unlocking.

  However, the power saving process involves stopping or limiting the functions of the portable information terminal, and it is determined which of the many functions of the portable information terminal should be performed. It is not easy for the user himself to make this determination. On the other hand, if the power saving process is executed while ignoring the user's usage status and wishes, the convenience may be significantly impaired.

  In addition, icons corresponding to a large number of power saving processes cannot be displayed on the lock screen, and even if a large number of icons can be displayed, an operation for selecting a necessary icon from among them is not possible. It is complicated.

  In addition, whether or not the power saving effect can be obtained by executing the power saving process depends on the user setting in the portable information terminal, and the power consumption restraining effect is different for each power saving process. . In addition, since how much power saving effect is required depends on the remaining battery level at that time, it is difficult for the user to select the power saving processing by judging these comprehensively. Met.

3 and 4 of JP2012-95069A.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a portable information terminal capable of executing appropriate power saving processing in a timely manner. Moreover, it aims at providing the portable information terminal which performs the power saving process selected by the user, without complicating user operation.

  In particular, it is an object of the present invention to provide a portable information terminal that can execute a power saving process when unlocking without complicating a user operation. It is another object of the present invention to provide a portable information terminal capable of executing appropriate power saving processing according to the remaining battery level.

  Moreover, it aims at providing the control method of such a portable information terminal. Furthermore, it aims at providing the computer program for such a portable information terminal.

  A portable information terminal according to a first aspect of the present invention displays an image on a display surface and selects an application program in a non-locked state in a portable information terminal provided with a touch panel that detects a touch operation on the display surface. A program selection screen for displaying on the display surface, and in a locked state, based on display control means for displaying the lock screen on the display surface and a user operation on the first unlocking operator on the lock screen, Based on the first unlocking means for transitioning the touch panel to the unlocked state and the user operation on the second unlocking operator on the lock screen, the touch panel is transitioned to the unlocked state and power saving processing is performed. Compared to the case where the first unlocking means makes a transition, the power consumption after the transition is reduced. Unlocking means and a remaining battery level detecting means for detecting the remaining battery level of the built-in battery, and the display control means has a second unlocking operator on the lock screen based on the remaining battery level. Configured to display.

  With such a configuration, the first and second unlocking operators are displayed on the lock screen, and the user can selectively operate the first and second unlocking operators. Further, when the second unlocking operation element is operated, the power saving process is executed together with the unlocking, and the subsequent power consumption is reduced as compared with the case where the first unlocking operation element is operated. can do.

  Therefore, if the user selects the unlocking operation element, the user can select to perform the power saving process at the time of unlocking, and can execute the power saving process based on the user's intention. Further, it is possible to allow the user to select whether or not to perform the power saving process without requiring an additional operation and without complicating the operation. Moreover, since the second unlocking operation element is displayed based on the remaining battery level of the built-in battery, if the user selects the second unlocking operation element, the power saving process according to the remaining battery level is performed. Can be executed.

  In addition to the above configuration, the portable information terminal according to the second aspect of the present invention recommends that the portable information terminal be executed at the time of unlocking based on the remaining battery level from among the two or more power saving processes. Recommended process selection means for selecting a process as a recommended process is provided, and the display control means is configured to display a second unlocking operator for executing the recommended process on the lock screen.

  With such a configuration, the power saving process recommended to be executed at the time of unlocking is selected as the recommended process from the two or more power saving processes, and the second unlocking for executing the recommended process is performed. The controls are displayed on the lock screen. For this reason, operability can be improved compared with the case where many 2nd unlocking operation elements are displayed on a lock screen according to the number of power saving processes.

  In the mobile information terminal according to the third aspect of the present invention, in addition to the above configuration, the recommended processing selection unit selects, as recommended processing, the number of power saving processes that does not exceed a predetermined recommended number, and performs the display control. The means is configured to display one or more second unlocking operators respectively associated with the recommended processing on the lock screen.

  With such a configuration, two or more power saving processes can be selected as the recommended processes within a predetermined recommended number range, and two or more second unlocking operators can be displayed. . For this reason, compared with the case where a large number of power saving processes are presented, two or more options for the power saving process can be shown without making it difficult for the user to select the second unlocking operator. .

  In the portable information terminal according to the fourth aspect of the present invention, in addition to the above-described configuration, two or more second unlocking operators displayed on the lock screen can be operated simultaneously by the user. When two unlocking operators are operated at the same time, two or more power saving processes respectively associated with the operated second unlocking operators are configured to be executed together.

  With such a configuration, when two or more second unlocking operators are displayed on the lock screen, two or more of these second unlocking operators can be selected together. Therefore, the user can select a combination of two or more power saving processes. Note that the simultaneous operation here refers to, for example, the user operation for the other second unlocking operator is started before the user operation for the one second unlocking operator is finished, and the respective operations are performed. Includes relationships where periods overlap.

  In addition to the above-described configuration, the portable information terminal according to the fifth aspect of the present invention is based on the storage means for holding the usage history and the battery consumption for each function targeted by the power saving process, and the usage history. Based on the battery consumption, two or more first candidate process selection means for selecting one or more of the power saving processes as the first candidate process from among the two or more power saving processes Second candidate process selection means for selecting one or more of the power saving processes as the second candidate process from among the power saving processes, wherein the recommended process selection means includes the battery remaining power The amount is compared with a predetermined threshold value, and if the remaining battery level exceeds the threshold value, the first candidate process is selected as the recommended process. The candidate process is selected as the recommended process. That.

  With this configuration, the first candidate process is selected based on the usage history for each function targeted by the power saving process, while the battery consumption for each function targeted by the power saving process is selected. Thus, the second candidate process is selected. Based on the remaining battery level, one of the first and second candidate processes is selected as the recommended process. That is, when selecting the recommended process, the power saving process is selected based on different criteria depending on the remaining battery level. For this reason, an appropriate power saving process can be selected.

  A mobile information terminal according to a sixth aspect of the present invention includes, in addition to the above configuration, a usage history measuring unit that measures the usage history and stores the usage history in the storage unit, and the first candidate processing selection unit includes the first candidate. As a process, it is configured to preferentially select a power saving process for the above function that is less frequently used.

  With such a configuration, it is possible to select a power saving process that is unlikely to impair user convenience as the recommended process. In particular, the user selects a more appropriate power saving process by adopting such a selection method in the selection of the first candidate process employed in the recommended process when the remaining battery level is relatively large. It becomes possible.

  In addition to the above-described configuration, the portable information terminal according to the seventh aspect of the present invention stores the user setting for specifying the operating state in advance for each function targeted by the power saving process. The first candidate process selection unit is configured to select a first candidate process for the function that is permitted to be executed based on the user setting.

  Even if a power saving process for a function that is not permitted to be executed is executed, the effect of reducing power consumption cannot be obtained. For this reason, if a power saving process targeting a function that is permitted to be executed is selected as the first candidate process based on the user setting, a power saving process that does not provide an effect of reducing power consumption is performed. An appropriate power saving process can be selected as the recommended process without being selected as the first candidate process.

  A mobile information terminal according to an eighth aspect of the present invention includes, in addition to the above configuration, a battery consumption measuring unit that measures the battery consumption and stores the measured battery consumption in the storage unit. As the candidate process, a power saving process for the above function that has a larger effect of reducing power consumption is preferentially selected.

  With such a configuration, it is possible to select a power saving process having a large effect of reducing power consumption as a recommended process. In particular, the user selects a more appropriate power saving process by adopting such a selection method in the selection of the second candidate process adopted for the recommended process when the remaining battery level is relatively low. It becomes possible.

  In addition to the above-described configuration, the portable information terminal according to the ninth aspect of the present invention stores the user setting for preliminarily designating the operation state for each function targeted by the power saving process. The second candidate process selection unit is configured to select a second candidate process for the function that is permitted to be executed based on the user setting.

  Even if a power saving process for a function that is not permitted to be executed is executed, the effect of reducing power consumption cannot be obtained. For this reason, if a power saving process targeting a function that is permitted to be executed is selected as the second candidate process based on the user setting, a power saving process that does not provide an effect of reducing power consumption is performed. An appropriate power saving process can be selected as the recommended process without being selected as the second candidate process.

  A portable information terminal according to a tenth aspect of the present invention includes, in addition to the above configuration, a user operation detection unit that detects a user operation for displaying the lock screen, and the display control unit is configured based on the user operation. The lock screen including a first unlocking operator is displayed, the recommended process selection means selects the recommended process based on the user operation, and the display control means has a first unlocking operator. The second unlocking operation element is displayed on the lock screen later than the above.

  With this configuration, the first unlocking operator can be displayed on the lock screen without waiting for the recommended process to be selected. When the recommended process is selected, the second unlock is performed. Operators can also be displayed on the lock screen. For this reason, when there is user operation for displaying a lock screen, a lock screen can be displayed quickly and operativity does not fall.

  A control method for a portable information terminal according to an eleventh aspect of the present invention is a method for controlling a portable information terminal comprising a touch panel that displays an image on a display surface and detects a touch operation on the display surface.

Embodiment 1 FIG.
FIG. 1 is an external view showing a configuration example of a portable information terminal according to Embodiment 1 of the present invention, in which a cellular phone 1 is shown as an example of a portable information terminal. The mobile phone 1 is composed of a thin casing having a substantially rectangular operation surface, and the receiver 1R, the touch panel 10 and the operation keys 11 are arranged in this order from the top on the operation surface that is in a vertically long state during a call. Is provided with a microphone 1M.

  The touch panel 10 is an input / output device configured by a display device 10A for displaying an image on a display surface and a touch sensor 10B for detecting a user's touch operation on the display surface. For example, a liquid crystal display device is used for the display device 10A, and a capacitive sensor is used for the touch sensor 10B. The operation key 11 is a contact type switch that detects a user's pressing operation. The receiver 1R and the microphone 1M are voice input / output devices for calls.

  When the user performs a touch operation on these operators while the display device 10A displays the operators on the display surface, the touch sensor 10B detects the operation position of the touch operation, The operator that has been touched is determined. The operation element is an icon displayed on the display surface, and includes, for example, a button or a slider icon. The touch operation includes, for example, a tap operation and a slide operation.

  In FIG. 1, a so-called smartphone is shown as an example of the mobile phone 1. However, the mobile information terminal according to the present invention may be a portable terminal provided with the touch panel 10, and may be a mobile phone other than the smartphone. Can also be applied. Further, the present invention is not limited to a terminal having a communication function or a call function, and can be applied to, for example, a tablet computer.

  FIG. 2 is a state transition diagram showing a change in the operation state of the touch panel 10 of FIG. The touch panel 10 transitions between a sleep state S1 in which the backlight is turned off and no display is performed, a lock state S2 in which a lock screen is displayed, and a non-lock state S3 in which a normal screen is displayed.

  The sleep state S1 is an operation state with the least power consumption. If no user operation is performed continuously for a certain period of time, the touch panel 10 shifts to the sleep state and suppresses power consumption. If the user performs a sleep return operation when the touch panel 10 is in the sleep state S1, the touch panel 10 shifts to the lock state S2, and a lock screen is displayed on the display surface. The sleep recovery operation is a user operation for displaying the lock screen, and includes, for example, a pressing operation on any one of the operation keys 11.

  If the user continues the unlock operation on the display surface, the lock is released. That is, the touch panel 10 shifts from the locked state S2 to the unlocked state S3, and a normal screen is displayed on the display surface.

  However, in any of the locked state S2 and the non-locked state S3, if no user operation is performed for a certain period of time, the process shifts to the sleep state S1. When authentication processing is performed at the time of unlocking, an authentication screen is displayed by unlocking operation, and authentication processing such as password authentication is performed. The transition to the unlocked state S3 is performed only when the authentication process is successful.

  FIG. 3 is a diagram showing an example of the normal screen NS displayed on the touch panel 10 of FIG. The normal screen NS is a screen that is displayed in an unlocked state, and a standby screen as shown in FIG. 3 is displayed immediately after unlocking. The standby screen is a program selection screen on which two or more icons 20 are displayed and an application program associated with the icon 20 can be activated by touching the arbitrary icon 20. After the application program is started, a screen generated by the application program is displayed as the normal screen NS, and after the application program ends, the standby screen is displayed again.

  FIG. 4 is a diagram showing an example of the lock screen displayed on the touch panel 10 of FIG. 1, (a) in the figure shows a general lock screen RS1, and (b) shows a power saving lock. Screen RS2 is shown. In the mobile phone 1, either the general lock screen RS1 or the power saving lock screen RS2 is displayed as a lock screen in the locked state. The general lock screen RS1 is provided with only the normal slider 21, whereas the power saving lock screen RS2 is provided with one or more power saving sliders 22 in addition to the normal slider 21.

  The normal slider 21 is a lock release operator for releasing the lock state, and includes an icon that is slidably displayed on the display surface of the touch panel 10. The user can display the normal screen by sliding the normal slider 21 to change the touch panel 10 from the locked state to the unlocked state.

  Similarly to the normal slider 21, the power saving slider 22 is an unlocking operation element for releasing the locked state, and includes an icon that is slidably displayed on the display surface of the touch panel 10. However, the operation of the power saving slider 22 is different from the case of operating the normal slider 21 in that not only unlocking but also power saving processing is performed.

  The power saving process is a process for reducing power consumption after unlocking by stopping or suppressing a process for realizing a specific function. For this reason, when the lock is released by operating the power saving slider 22, the power consumption in the subsequent unlocked state can be reduced compared to the case where the lock is released by operating the normal slider 21.

  The cellular phone 1 selects, as a recommended process, a power saving process that is recommended to be executed when unlocking, from among two or more predetermined power saving processes. Each power saving process is associated with a different function, and by changing the user setting of the corresponding function from on (valid) to off (invalid), or by reducing the grade level of the function, Reduce power consumption. The selection of the recommended process is performed based on the internal state of the mobile phone 1 at that time, that is, based on the internal state in the locked state after the sleep release operation is performed. For example, it is performed based on the remaining battery capacity, user settings for each function, usage history, battery consumption, or the like.

  The power saving slider 22 corresponding to the recommended process selected in this way is arranged on the screen together with the normal slider 21 to form the power saving lock screen RS2. In FIG. 4, in addition to the normal slider 21, the power saving slider 22 associated with the power saving processing for turning off (invalidating) the user setting of the background operation of the map application, and the WLAN (Wireless Local Area Network) A power saving slider 22 associated with the power saving process for turning off (invalidating) the user setting is displayed in the lock screen.

  The general lock screen RS1 is displayed when the recommended process cannot be selected. For example, when the user setting is off (invalid) for all the functions to be subjected to the power saving process, there is no power saving process to be recommended, and thus the power saving slider 22 is not arranged. The lock screen RS1 is displayed.

  In addition, here, an example in which one power saving process is associated with one power saving slider 22 has been described, but two or more power saving processes are performed with respect to one power saving slider 22. It can also be associated.

  5 to 7 are diagrams showing an example of the unlocking operation on the power saving lock screen RS2. FIG. 5 is a diagram illustrating a state in which the user slides the normal slider 21 to release the locked state. First, the normal slider 21 can be moved by bringing the fingertip into contact with the normal slider 21 and then moving the fingertip to the right without leaving the display surface. At this time, if the fingertip is moved away from the display surface without moving the normal slider 21 to the right end, the normal slider 21 returns to the left end position, but the fingertip is moved to the right end while the normal slider 21 is moved to the right end. If released, the locked state is released and the locked state is entered.

  FIG. 6 is a diagram illustrating a state in which the user slides the power saving slider 22 to release the locked state. The operation for the power saving slider 22 is exactly the same as the sliding operation for the normal slider 21.

  FIG. 7 is a diagram showing how the user slides two power saving sliders 22 at the same time. When the touch panel 10 can detect multi-touch, the two power saving sliders 22 can be operated simultaneously. That is, if the two fingertips are respectively brought into contact with the two power saving sliders 22 and then moved to the right without moving the two fingertips away from the display surface, the two power saving sliders 22 are moved together. be able to. When both the power saving sliders 22 are moved to the right end and the fingertip is moved away from the display surface, the power saving process associated with the power saving slider is executed.

  Whether or not the two power-saving sliders 22 are simultaneously slid can be determined, for example, by the operation of the other power-saving slider 22 being started before the operation for one power-saving slider 22 is completed. This can be determined by whether or not the operation periods for the power slider 22 overlap. That is, if the user's finger touches the other power saving slider 22 before the user's finger leaves the one power saving slider 22, it can be determined that these power saving sliders 22 are operated simultaneously. .

  That is, the operation on the power saving slider 22 is the same as the operation on the normal slider 21, and the unlocking power saving process can be executed without complicating the user operation. Further, whether or not to perform the power saving process is performed by selecting a slider to be operated, so that the intention of the user can be reflected and the convenience is not impaired. Furthermore, among the many power saving processes, only the recommended power saving process is selected as the recommended process, and only the power saving slider 22 corresponding to the recommended process is displayed. The selection is not complicated.

  FIG. 8 is a block diagram showing an example of the internal configuration of the mobile phone 1 of FIG. 1, showing an example of the main circuit configuration. The cellular phone 1 includes a processor 12 that performs main control, a wireless communication unit 13 that performs wireless communication with a cellular base station via an antenna, and a battery remaining capacity that detects a remaining capacity of a built-in battery (not shown). A quantity detection unit 14, one or more peripheral circuits 15 </ b> A to 15 </ b> D, and a storage device 16 are provided.

  Here, as peripheral circuits, a WLAN control unit 15A that performs wireless communication with an access point, a Bluetooth (registered trademark) control unit 15B that performs wireless communication with a peripheral device, and receives satellite signals to obtain position information. It is assumed that a GPS (Global Positioning System) control unit 15C to be acquired and a pedometer 15D for counting the number of steps of the user are provided. All of the functions realized using these peripheral circuits are targets for power saving processing.

  The storage device 16 is a storage unit that holds data used by the processor 12, and for example, a flash memory is used. Here, it is assumed that the user setting 16A, the usage history 16B, and the battery consumption 16C are held in the storage device 16 as data for each function that is a target of the power saving process.

  The display device 10 </ b> A includes a display panel 101 and a backlight 102. The display panel 101 is a transmissive liquid crystal display panel, and an image can be displayed by turning on the backlight 102. That is, the backlight 102 is turned off in the sleep state, and the backlight is turned on in the locked state and the unlocked state. Further, the brightness of the display device 10 </ b> A is adjusted by the brightness of the backlight 102.

  FIG. 9 is a diagram showing an example of user settings 16A held in the storage device 16 of FIG. The user setting 16A is data designated in advance by the user for each function that is a target of the power saving process. In other words, the “function” here is associated with the user setting 16A, and can also be referred to as the user setting 16A.

  Therefore, the function that is the target of the power saving process is not limited to the function that is realized by using the peripheral circuits 15A to 15D, and the function that is realized by executing the application program is also the target of the power saving process. can do. Here, a function realized mainly using the peripheral circuits 15A to 15D is called a “hardware function”, and a function realized mainly by executing an application program is called a “software function”.

  The user setting 16A is data indicating the operation state of the corresponding function, and includes data indicating ON or OFF, or data indicating a grade level. The function on / off means whether or not to execute processing for realizing the function. When the function is turned off, power consumption can be reduced compared to when the function is turned on. The grade level means the quality or performance of the function to be realized, for example, the processing accuracy, processing frequency, output value, etc. directly connected to these, and the power consumption for realizing the function depends on the grade level. Change.

  FIG. 9A shows user settings 16A related to hardware functions. For the WLAN control unit 15A, the Bluetooth control unit 15B, the GPS control unit 15C, and the pedometer 15D, ON or OFF is specified as the user setting 16A, and for the backlight 102, the luminance level of 1 to 5 is set as the user setting 16A. It is specified.

  In the figure, the WLAN control unit 15A is “on”, the Bluetooth control unit 15B is “off”, the GPS control unit 15C is “on”, the pedometer 15D is “on”, and the luminance level of the backlight 102 is “3”. An example in the case where the user specifies is shown.

  FIG. 9B shows a user setting 16A related to the software function. The application software is executed by a user's starting operation that explicitly specifies the application program. Therefore, the user setting 16A for the software function specifies whether or not to allow the application program operating in the background to operate in the background, or the frequency of operating in the background.

  Here, for each application program of SNS, mail, map, and music, whether or not background operation is permitted is designated as the user setting 16A. In the drawing, an example is shown in which “ON” for SNS, “OFF” for mail, “ON” for maps, and “ON” for music are specified by the user.

  FIG. 10 is a diagram showing an example of the usage history 16B held in the storage device 16 of FIG. The usage history 16B is the usage frequency measured for each function that is the target of the power saving process, and includes, for example, the number of times of use or the cumulative usage time within a certain past period. Here, it is assumed that the accumulated usage time in the most recent week is held as the usage history 16B. The usage history 16B is intended only for hardware functions and not for software functions.

  Here, an example in which the WLAN control unit 15A is “60 minutes”, the Bluetooth control unit 15B is “5 minutes”, the GPS control unit 15C is “10 minutes”, and the pedometer 15D is “2400 minutes” is shown. ing. Note that the usage history 16B is not exceptionally measured for the backlight 102 because it is not appropriate to select a recommended process in consideration of its use frequency as a single function.

  FIG. 11 is a diagram showing an example of the battery consumption 16C held in the storage device 16 of FIG. The battery consumption 16C is power consumption per unit time obtained for each function that is a target of power saving processing.

  For the hardware function, if the power consumption per unit time is known, the value can be used as the battery consumption 16C. However, when the power consumption by the function can be measured by the measuring means in the mobile phone 1, the measured value of the power consumption per unit time measured in the state where the hardware function is used is the battery consumption 16C. Can also be used.

  On the other hand, for the software function, it is possible to measure the occupancy time that the background operation of the application program occupies the processor 12 and obtain the battery consumption 16C from the occupancy time within a certain period. In this case, even if the application program is different, if the occupation time of the processor 12 is constant, the battery consumption 16C may be obtained on the assumption that the power consumption of the processor 12 is constant. It is also possible to obtain a product with a different load coefficient for each application to obtain the battery consumption 16C. Needless to say, the fixed period for obtaining the battery consumption 16C does not have to coincide with the fixed period for obtaining the usage history 16B.

  FIG. 11A shows the battery consumption 16C of each hardware function. Here, an example is shown in which the WLAN controller 15A is “10”, the Bluetooth controller 15B is “8”, the GPS controller 15C is “5”, and the pedometer 15D is “1”. These power consumption amounts are all values during operation, and all the values during stop are zero. Moreover, the backlight 102 also changes the battery consumption 16C to 1-5 according to the luminance levels 1-5.

  FIG. 11 (b) shows the processor occupation time and battery consumption 16C for each software function. Here, as for the processor occupation time, an example is shown in which the SNS is “5 minutes”, the mail is “1 minute”, the map is “10 minutes”, and the music is “1 minute”. Further, the processor occupation time is used as it is as the battery consumption 16C. That is, the battery consumption 16C shows an example in which the SNS is “5”, the mail is “1”, the map is “10”, and the music is “1”.

  FIG. 12 is a block diagram showing an example of the internal configuration of the mobile phone 1 of FIG. 1, showing an example of the main functional configuration. The usage history measuring unit 120, the battery consumption measuring unit 121, the first candidate process selecting unit 122, the second candidate process selecting unit 123, the recommended process selecting unit 124, and the display control unit 125 shown in FIG. These are functional blocks realized by the processor 12 executing a computer program.

  The usage history measurement unit 120 obtains the usage history 16B for each function and stores it in the storage device 16. The battery consumption measuring unit 121 obtains the battery consumption 16C for each function and stores it in the storage device 16.

  The first candidate process selection unit 122 performs one or more power saving processes among the two or more predetermined power saving processes based on the user setting 16A and the usage history 16B. And the selection result is output to the recommended process selection unit 124. In the first candidate process selection unit 122, a power saving process corresponding to a function that can be expected to reduce power consumption and is less frequently used is selected as a candidate process. Further, the number of power saving processes to be selected is selected so as not to exceed a predetermined recommended number Nr. The recommended number Nr is predetermined as an integer value of 3 or less, for example.

  First, based on the user setting 16A, a power saving process that can be expected to reduce power consumption is extracted. Specifically, only the power saving process for the function whose current user setting 16A is “ON” is extracted. If the current user setting 16A is “off”, power consumption cannot be reduced even if the user setting 16A is changed. Therefore, power saving corresponding to the function in which the user setting 16A is “on” is possible. Narrow down to processing only.

  Next, based on the use history 16B, priority is given to a power saving process corresponding to a function that is used less frequently, and candidate processes are selected until the recommended number Nr is reached. A function that is not frequently used is unlikely to significantly reduce convenience even if the user setting is changed from on to off. For this reason, the first candidate process selection unit 122 compares the use frequencies relatively and selects a power saving process with a lower use frequency as a candidate process.

  For example, in the first candidate process selection unit 122, the first candidate process is selected from the power saving processes for each function except the backlight 102 among the hardware functions shown in FIG. Is done. That is, a candidate process is selected from the four power saving processes targeting the WLAN control unit 15A, the Bluetooth control unit 15B, the GPS control unit 15C, and the pedometer 15D. The recommended number Nr is assumed to be two.

  The second candidate process selection unit 123 selects one or more power saving processes among the two or more predetermined power saving processes based on the user setting 16A and the battery consumption 16C as the second candidate. The process is selected, and the selection result is output to the recommended process selection unit 124. In the second candidate process selection unit 123, a power saving process having a greater effect of reducing power consumption is selected as a candidate process. Further, the number of candidate processes to be selected is selected so as not to exceed a predetermined recommended number Nr.

  First, as in the case of the first candidate process selection unit 122, a power saving process that can be expected to reduce power consumption is extracted based on the user setting 16A. Specifically, only the power saving process for the function whose current user setting 16A is “ON” is extracted.

  Next, based on the battery consumption 16C, priority is given to a power saving process targeting a function with a greater effect of reducing power consumption, and candidate processes are selected until the recommended number Nr is reached. If the user setting 16A is changed from “on” to “off” for a function having a large battery consumption 16C, a greater power consumption reduction effect can be obtained. In the case of the backlight 102 with adjustable brightness level, the battery consumption can be reduced by reducing the brightness level. For this reason, the second candidate process selection unit 123 relatively compares battery consumptions that can be reduced for each function, and selects a candidate process that has a greater effect of reducing power consumption as a candidate process.

  For example, the second candidate process selection unit 123 selects a candidate process from nine power saving processes targeted for the hardware function and the software function shown in FIG.

  The recommended process selection unit 124 selects one or more power saving processes as recommended processes based on the remaining battery level, and outputs the selected process to the display control unit 125. The recommended process selection unit 124 receives the selection result of the first candidate process selected based on the usage frequency and the selection result of the second candidate process selected based on the battery consumption. One of these selection results is adopted as a recommended process in the recommended process selection unit 124. In other words, the recommended process selection unit 124 designates one of the first candidate process selection unit 122 and the second candidate process selection unit 123 as a recommended process selection unit based on the remaining battery level. Yes.

  First, the recommended process selection unit 124 compares the remaining battery level of the built-in battery detected by the remaining battery level detection unit 14 with a predetermined threshold value. As a result, when the remaining battery level exceeds the threshold value, it is determined that the remaining battery level is high. In this case, the first candidate process selected by the first candidate process selection unit 122 is adopted as the recommendation process. On the other hand, if the remaining battery level is less than or equal to the threshold, it is determined that the remaining battery level is low. In this case, the second candidate process selected by the second candidate process selection unit 123 is adopted as the recommendation process.

  When selecting one of the two or more power saving processes, it becomes a problem whether to give priority to the convenience of the user or the power saving effect. Therefore, the first candidate process selection unit 122 selects candidate processes with priority on convenience, and the second candidate process selection unit 123 selects candidate processes with priority on the power saving effect. The recommended process selection unit 124 prioritizes convenience when the remaining battery level is high, adopts the selection result of the first candidate process selection unit 122, and saves power when the remaining battery level is low. The selection result of the second candidate process selection unit 123 is adopted with priority on the effect.

  The display control unit 125 generates image data such as a lock screen and a normal screen and outputs the image data to the display panel 101. That is, the image data of the lock screen is generated by the display control unit 125 based on the selection result of the recommended process selection unit 124. When the recommended process is selected by the recommended process selection unit 124, image data of the power saving lock screen RS2 including the normal slider 21 and one or more power saving sliders 22 associated with the recommended process is generated. Is done. On the other hand, when the recommended process is not selected by the recommended process selection unit 124, image data of the general lock screen RS1 that does not include the power saving slider 22 is generated. Each power saving slider 22 clearly indicates the function to be subjected to the power saving process with characters or icons so that the user can select the power saving slider 22 according to the usage status of his / her mobile phone 1. It is desirable to do.

  Steps S101 to S104 in FIG. 13 are flowcharts showing an example of the operation of the mobile phone 1, and show the procedure of the lock screen display process. This display process is started when a sleep cancel operation is performed. First, one or more recommended processes are selected from two or more predetermined power saving processes (step S101). At this time, when the recommended process is not selected, that is, when the power saving process to be recommended for the user is not found, the general lock screen RS1 is displayed (steps S102 and S103). On the other hand, when one or more recommended processes are selected, the power saving lock screen RS2 is displayed (step S104).

  Steps S201 to S203 in FIG. 14 are flowcharts showing an example of the operation of the mobile phone 1, and show the procedure of the unlocking process. This unlocking process is started when either the normal slider 21 or the power saving slider displayed on the lock screen is operated.

  First, it is determined whether or not the operated slider is the power saving slider 22 (step S201). If the power saving slider 22 has been operated, a power saving process associated with the operated power saving slider 22 is executed (step S202). Specifically, the user setting 16A of the function targeted for the power saving process is switched from “on” to “off”, or the grade level of the function is lowered.

  When two or more power saving processes are associated with one power saving slider 22, these power saving processes are executed in order. Further, as shown in FIG. 7, when two or more power saving sliders 22 are operated simultaneously by the user, the power saving processing associated with each power saving slider 22 is sequentially executed.

  When all the power saving processes are finished, the normal screen NS is displayed, and the unlocking process is finished (step S203).

  On the other hand, when it is determined in step S201 that the power saving slider 22 is not operated, that is, when the normal slider 21 is operated, the normal screen NS is displayed without performing the power saving process. Then, the unlocking process ends (step S203).

  Steps S301 to S308 in FIG. 15 are flowcharts showing the detailed procedure for selecting the recommended process (step S101) shown in FIG. First, a function capable of reducing power consumption is extracted (step S101). That is, in the case where the user setting 16A is a function that is “ON” or “OFF”, the function that is “ON” is extracted. Further, when the user setting 16A is a function having a grade level, a function other than the lowest level is extracted.

  Next, the usage frequency for each extracted function is obtained (step S302). The use frequency is measured by the use history measuring unit 120 and is obtained based on the use history 16B held in the storage device 16. If the usage history 16B can be used as the usage frequency as it is, it is only necessary to refer to the usage history 16B.

  Based on the frequency of use, a first candidate process is selected from two or more power saving processes (step S303). This selection process is performed in the first candidate process selection unit 122, and one or two or more power saving processes are first performed so that priority is given to a power saving process for a function that is used less frequently. Selected as a candidate process.

  Next, the battery consumption for each function extracted in step S301 is obtained (step S304). The battery consumption is measured by the battery consumption measuring unit 121 and obtained based on the battery consumption 16C held in the storage device 16. If the battery consumption 16C can be used as it is, it is only necessary to refer to the battery consumption 16C.

  Based on the battery consumption, a second candidate process is selected from two or more power saving processes (step S305). This selection process is performed by the second candidate process selection unit 123, and one or two or more power saving processes are performed so that priority is given to a power saving process targeting a function with less battery consumption. Is selected as the second candidate process.

  Next, the remaining battery level is compared with a threshold value to determine whether the remaining battery level is relatively large and sufficient, or whether the remaining battery level is relatively small and is in a tight state (step) S306).

  If the remaining battery level exceeds the threshold value, the first candidate process selected in step S303 is selected as the recommended process, and the process ends (step S307). That is, when the remaining battery level is relatively large and there is still room, a power saving process that is estimated to have a small effect on user convenience is selected as the recommended process.

  On the other hand, if the remaining battery level is not exceeded, the second candidate process selected in step S305 is selected as the recommended process, and the process ends (step S308). That is, when the remaining amount of the battery is relatively small, the power saving process with a large effect of reducing the power consumption is selected as the recommended process.

  As understood from the above description, the characteristics of the mobile phone 1 according to the present embodiment are summarized as follows.

  The mobile phone 1 according to the first embodiment of the present invention displays the normal screen NS in the unlocked state S3 and the display control unit 125 that displays the power saving lock screen RS2 in the locked state S2, and the power saving lock screen RS2. Based on the user operation on the normal slider 21, the first unlocking means for transitioning to the unlocked state, and on the basis of the user operation on the power saving slider 22 on the power saving lock screen RS 2, the transition to the unlocked state and saving Compared to the case where the transition is made by operating the power slider and operating the normal slider 21, the second unlocking means for suppressing the power consumption in the unlocked state S3 and the remaining battery level for detecting the remaining battery level of the built-in battery And the display control unit 125 displays the power saving slider 22 on the power saving lock screen RS2 based on the remaining battery level. Configured to.

  Therefore, the normal slider 21 and the power saving slider 22 are displayed on the power saving lock screen RS2, and the user can selectively operate these sliders 21 and 22. Further, when the power saving slider 22 is operated, the power saving process is executed together with the unlocking, and the subsequent power consumption can be reduced compared to the case where the normal slider 21 is operated. Therefore, if the user selects the power saving slider 22, the user can select to perform the power saving process when unlocking, and can execute the power saving process based on the user's intention. Further, it is possible to allow the user to select whether or not to perform the power saving process without requiring an additional operation and without complicating the operation. Moreover, since the power saving slider 22 is displayed based on the remaining battery level of the built-in battery, if the user selects the power saving slider 22, the user can execute the power saving process according to the remaining battery level. .

  In addition, the mobile phone 1 according to Embodiment 1 of the present invention uses, as a recommended process, a power saving process that is recommended to be executed at the time of unlocking based on the remaining battery level from among two or more power saving processes. A recommended process selection unit 124 to be selected is provided, and the display control unit 125 is configured to display the power saving slider 22 for executing the recommended process on the lock screen. For this reason, the power saving process recommended to be executed when unlocking is selected as the recommended process from the two or more power saving processes, and the power saving slider 22 for executing the recommended process is set to the power saving lock. It is displayed on the screen RS2. Therefore, the operability can be improved in comparison with the case where a large number of power saving sliders 22 are displayed on the power saving lock screen RS2 in accordance with the number of power saving processes.

  Further, in the mobile phone 1 according to the first embodiment of the present invention, the recommended process selection unit 124 selects the number of power saving processes that do not exceed the predetermined recommended number Nr as the recommended process, and the display control unit 125 One or two or more power saving sliders 22 respectively associated with the recommended processes are configured to be displayed on the power saving lock screen RS2. For this reason, within the range of the recommended number Nr, two or more power saving processes can be selected as the recommended processes, and two or more power saving sliders 22 can be displayed. Therefore, two or more options can be shown for the power saving process without making it difficult for the user to make a selection decision on the power saving slider 22.

  Further, in the mobile phone 1 according to Embodiment 1 of the present invention, the two or more power saving sliders 22 displayed on the power saving lock screen RS2 can be operated simultaneously by the user, and the two or more power saving sliders 22 can be operated simultaneously. Are operated simultaneously, two or more power saving processes respectively associated with the operated power saving sliders 22 are executed together. For this reason, when two or more power saving sliders 22 are displayed on the lock screen, two or more of these power saving sliders 22 can be selected together. Therefore, the user can select a combination of two or more power saving processes.

  In addition, the mobile phone 1 according to the first embodiment of the present invention includes two or more power saving processes based on the storage device 16 that holds the usage history 16B and the battery consumption 16C for each function, and the usage history 16B. Based on the first candidate process selection unit 122 that selects one or two or more power saving processes as the first candidate process, and the battery consumption 16C, one of the two or more power saving processes is 1 Or a second candidate process selection unit 123 that selects two or more power saving processes as the second candidate process, and the recommended process selection unit 124 compares the remaining battery level with a predetermined threshold value, If the remaining amount exceeds the threshold value, the first candidate process is selected as the recommended process, while if the remaining battery level is equal to or less than the threshold value, the second candidate process is selected as the recommended process.

  Therefore, the first candidate process is selected based on the usage history 16B for each function, while the second candidate process is selected based on the battery consumption 16C for each function. Based on the remaining battery level, one of the first and second candidate processes is selected as the recommended process. That is, when selecting the recommended process, the power saving process is selected based on different criteria depending on the remaining battery level. For this reason, an appropriate power saving process can be selected.

  In addition, the mobile phone 1 according to the first embodiment of the present invention includes the usage history measurement unit 120 that measures the usage history 16B and stores the usage history 16B in the storage device 16, and the first candidate processing selection unit 122 includes the first candidate. As a process, it is configured to preferentially select a power saving process for a function having a lower usage frequency. For this reason, it is possible to select a power saving process that is unlikely to impair user convenience as the recommended process. In particular, the user selects a more appropriate power saving process by adopting such a selection method in the selection of the first candidate process employed in the recommended process when the remaining battery level is relatively large. It becomes possible.

  Further, in the mobile phone 1 according to the first embodiment of the present invention, the storage device 16 holds the user setting 16A for preliminarily specifying the operation state for each function, and the first candidate process selection unit 122 is configured as a user setting. Based on 16A, it is configured to select a first candidate process for a function that is permitted to be executed. For this reason, the power saving process in which the effect of reducing power consumption cannot be obtained is not selected as the first candidate process, and an appropriate power saving process can be selected as the recommended process.

  In addition, the mobile phone 1 according to the first embodiment of the present invention includes a battery consumption measuring unit 121 that measures the battery consumption 16C and stores it in the storage device 16, and the second candidate process selection unit 123 includes the second candidate process selection unit 123. As the candidate process, a power saving process for a function having a greater effect of reducing power consumption is preferentially selected. For this reason, it is possible to select a power saving process having a large effect of reducing power consumption as the recommended process. In particular, the user selects a more appropriate power saving process by adopting such a selection method in the selection of the second candidate process adopted for the recommended process when the remaining battery level is relatively low. It becomes possible.

  Further, in the mobile phone 1 according to the first embodiment of the present invention, the storage device 16 holds the user setting 16A for preliminarily specifying the operation state for each function, and the second candidate process selection unit 123 has the user setting. Based on 16A, it is configured to select a second candidate process for a function that is permitted to be executed. For this reason, the power saving process in which the effect of reducing power consumption cannot be obtained is not selected as the second candidate process, and an appropriate power saving process can be selected as the recommended process.

Embodiment 2. FIG.
Steps S401 to S404 in FIG. 16 are flowcharts showing another example of the lock screen display processing procedure. That is, a processing procedure that changes to the processing procedure of FIG. 13 is shown. The flowchart of FIG. 16 is started when the sleep release operation is performed, and first, the general lock screen RS1 is displayed (step S401). Thereafter, the recommended process is selected (step S402). When the recommended process is selected, the general lock screen RS1 is changed to the power saving lock screen RS2 (steps S403 and S404). On the other hand, when the recommended process is not selected, the general lock screen RS1 is continuously displayed as it is.

  If the flowchart of FIG. 16 is compared with the flowchart of FIG. 13, the conditions and timing for displaying the general lock screen RS1 are different. In the flowchart of FIG. 13, the recommended process is selected first (step S101), and then the lock screen is displayed (steps S103 and S104). For this reason, when it takes time to select a recommended process, there is a possibility that a time lag occurs after the sleep release operation is performed until the lock screen is displayed, thereby reducing the operability. On the other hand, if the processing procedure of FIG. 16 is adopted, when the sleep release operation is performed, the general lock screen RS1 is immediately displayed, and the power saving slider 22 is added in the screen with a slight delay, thereby saving the power saving lock. The screen shifts to the screen RS2. For this reason, the power saving lock screen RS2 can be displayed without deteriorating operability.

  The mobile phone 1 according to the second embodiment of the present invention includes user operation detection means for detecting a user operation for displaying a lock screen, and the display control unit 125 includes a normal slider 21 based on the user operation. The lock screen is displayed, the recommended process selection unit 124 selects the recommended process based on the user operation, and the display control unit 125 displays the power saving slider 22 on the lock screen later than the normal slider 21. Configured. Therefore, the normal slider 21 can be displayed on the lock screen without waiting for the recommended process to be selected, and the power saving slider 22 can also be displayed on the lock screen when the recommended process is selected. Can do. For this reason, when there is user operation for displaying a lock screen, a lock screen can be displayed quickly and operativity does not fall.

  In the above-described embodiment, an example in which the first candidate process selection unit 122 selects the first candidate process based on the user setting 16A and the usage history 16B has been described. Twenty-two unselected histories can also be considered. The non-selection history of the power saving slider is a history for each power saving slider 22 that has been displayed on the power saving lock screen RS2 in the past but has not been selected by the user, and power saving corresponding to the power saving slider 22 is performed. The process may be configured to perform a correction that lowers the priority when the first candidate process is selected. For example, the power saving process corresponding to the power saving slider 22 that is displayed three times on the power saving lock screen RS2 but has not been selected by the user once is the first until the fixed period elapses. The candidate process selection unit 122 can be configured not to be selected as the first candidate process.

  In the above embodiment, an example has been described in which the second candidate process selection unit 123 selects the second candidate process based on the user setting 16A and the battery consumption 16C. The non-selection history of the slider 22 can also be considered. That is, for the power saving process corresponding to the power saving slider 22 displayed on the power saving lock screen RS2 based on the non-selection history but not selected by the user, the second candidate process is selected. You may comprise so that the correction which lowers a priority may be performed. For example, the power saving process corresponding to the power saving slider 22 that has been displayed three times on the power saving lock screen RS2 but has not been selected by the user once is the second until a certain period elapses. The candidate process selection unit 123 can be configured not to be selected as the second candidate process.

  Furthermore, in the above embodiment, the normal slider 21 and the power saving slider 22 are displayed on the power saving lock screen RS2, and the locked state is released by the user performing a sliding operation on these sliders 21 and 22. However, the present invention is not limited to such a case. For example, instead of the sliders 21 and 22, icons that do not slide may be displayed, and the locked state may be released by a user tap operation or double tap operation on the icon display area.
