  Embodiments of the present invention will be described with reference to the accompanying drawings. The embodiments described below are examples of the present invention, and the present invention is not limited to the following embodiments. In the present specification and drawings, the same reference numerals denote the same components.

Embodiment 1 FIG.
The configuration of the electronic device according to the present embodiment will be described with reference to FIG. FIG. 1 is a block diagram illustrating a main part of the electronic device 10. The electronic device 10 according to the present embodiment includes a CPU 1, a display unit 2, a storage unit 3, a notification unit 4, and an operation unit 5. CPU12 is connected with the display part 2, the memory | storage part 3, the alerting | reporting part 4, and the operation part 5 via the bus | bath, and controls these.

  The display unit 2 includes a display device such as a monochrome or color liquid crystal panel or an organic EL (electrofluorescence). The display unit 2 displays information related to settings and other information. For example, when the electronic device 10 is a mobile phone terminal, information necessary for making a telephone call or mail is displayed on the display unit 2.

  The storage unit 3 has storage means such as a RAM (Random Access Memory) and a ROM (Read Only Memory). The storage unit 3 stores data temporarily required for the CPU 1 to execute the program. Furthermore, the storage unit 3 stores a program for executing the control method of the portable electronic device according to the present embodiment.

  The notification unit 4 includes a speaker and an acoustic control unit for controlling the speaker. Sound can be generated from the speaker via the sound control unit provided in the notification unit 4. The notification unit 4 is used for daily alarms and operation sounds. Or the alerting | reporting part 4 outputs a ringtone, a dial tone, etc. Furthermore, the alerting | reporting part 4 may have light source means, such as LED. By doing so, it is also possible to notify by light from the light source.

  The operation unit 5 includes various input keys and an input circuit that receives key inputs. That is, the operation unit 5 serves as input means having buttons such as numeric keys. The operation unit 5 may have a touch panel or the like. When the user operates the operation unit 5, the CPU 1 executes a process based on the operation. Thereby, the display part 2 performs the display according to operation. The storage unit 3 stores operation details as necessary. Furthermore, the alerting | reporting part 4 outputs the sound and light for alerting | reporting to a user according to operation.

  The user scans the operation unit 5 in order to change the setting. That is, the operation unit 5 is an input unit that receives an input for changing the setting of the electronic device 10. For example, it is assumed that the user changes the setting of the electronic device 10 by operating an input key, a touch panel, or the like. In this case, the CPU 1 changes the setting of the electronic device 10 based on a setting change operation. Furthermore, the setting change history of the electronic device 10 is stored in the storage unit 3. The settings of the electronic device 10 include display settings on the display unit 2, settings such as a notification sound in the notification unit 4, or camera settings (photographing settings) such as a camera (not shown). When the user changes the setting, the electronic device 10 operates with the setting.

  When the user performs a key operation (hereinafter referred to as a setting return operation) for returning the setting change with the operation unit 5, a setting change history for returning the setting change to the original is displayed on the display unit 2. Then, in a state where the setting change history is displayed on the display unit 2, the user operates the operation unit 5 to designate setting changes in the setting change history. The CPU 1 returns the setting of the electronic device 10 to the state before the designated change setting. A key for returning the setting change may be assigned to a dedicated key in the operation unit 5.

  FIG. 2 shows a screen for undoing the setting change. On the display screen, a setting change history table 6 serving as a setting change history is shown. The setting change history table 6 shows each input setting change as a list. Further, for each setting change, the change date and time and the change contents are stored in association with each other. The setting change history table 6 stores changed settings in chronological order. For example, at 07:21 on November 10, 2010, the camera macro setting is changed from OFF to ON, which is the most recently changed setting. Before that, the camera shooting size was changed from 13M to 5M at 07:20 on November 10, 2010. Further, before that, at 23:42 on November 9, 2010, the setting is changed so that the alarm setting in the notification unit 4 is turned ON from OFF to 7:00. Before that, at 23:42 on November 9, 2010, the display brightness setting on the display unit 2 is changed from 3 to 4.

  Thus, the setting change along the time series is stored in the storage unit 3 as the setting change history table 6. Further, the displayed setting change history table 6 includes information before the setting change and information after the setting change. For example, in the case of changing the shooting size setting, the setting value before the setting change (13M) and the setting value after the setting change (5M) are displayed. Information before and after each setting change is displayed as a list associated with the change time. In FIG. 2, four setting change contents are shown as the setting change history, but the number of setting changes displayed on one display screen of the display unit 2 is not particularly limited. In addition, when the setting is changed many times and not all setting change images can be displayed on one display screen, the screen may be scrolled to display. When the user designates a setting change from the setting change history table 6, the setting can be returned to the state before the change.

  Next, processing for displaying the setting change history table will be described with reference to FIG. FIG. 3 is a flowchart showing processing for displaying the setting change history table. First, it is determined whether or not a setting return operation has been performed by the user (step S21). When the setting return operation key is operated on the operation unit 5 (Yes in step S21), the CPU 1 detects this. On the other hand, when the setting return operation key is not operated on the operation unit 5 (No in step S21), the determination in step S21 is performed until the user operates. In the operation unit 5, a specific key can be assigned as a setting return operation key. Alternatively, an icon for starting the setting return process may be displayed on the display unit 2. By selecting the setting return icon, processing for returning the setting is started.

  When the setting return operation key is operated, a setting change history is acquired (step S22). That is, the CPU 1 reads the setting change history data stored in the storage unit 3. Then, the setting change history is displayed (step S23). As a result, the display unit 2 displays the setting change history table 6 shown in FIG. In the displayed setting change history table 6, information before and after the setting change is displayed together with the change date and time. Thereby, the user can easily recognize the changed content.

  Next, the process of returning to the state before changing the setting will be described with reference to FIG. FIG. 4 is a flowchart showing a process for restoring the changed setting. Steps S31 to S33 in FIG. 4 are the same as steps S21 to S23 in FIG. In step S33, after the setting change history is displayed, it is determined whether there is an instruction to return the designated setting (step S34). That is, when the user selects one setting content to be returned from the setting change history table (Yes in step S34), a process of returning the designated setting content to the state before the change is performed. (Step S35).

  If there is not one setting that the user wants to return (No in step S34), it is determined whether or not all the settings to be specified are to be returned (step S36). That is, when it is desired to return a plurality of settings changed by the user at once, the following processing is performed. When the user performs an operation to return everything from the immediately preceding setting return operation to the specified setting content (Yes in step S36), a process is performed to return all the specified setting content to the state before the change (step S36). Step S37). As a result, the settings can be collectively returned to the state immediately before the designated settings.

  When the user does not perform an operation of returning all the specified setting contents to the state before the change (No in step S36), it is determined whether or not the setting to be returned is specified by a date (step S38). When the user specifies the setting to be returned by date (Yes in step S38), a process for returning the setting of the specified date and time is performed (step S39). As a result, the settings can be returned collectively to the state immediately before the designated date and time. If the user does not specify the setting to be returned by date (No in step S38), the process returns to step S33.

  By specifying the setting change from the setting change history displayed on the display unit 2, it is possible to return to the state before the setting change. The user can undo the setting change while confirming the information before and after the setting change. Therefore, it is possible to appropriately restore the setting changed by an erroneous operation. That is, it is possible to restore only the setting changed by an erroneous operation without restoring the appropriately changed setting. It is also possible to restore all specified settings at once. Furthermore, by designating the date and time, all setting changes up to the designated date and time can be reset. When a plurality of setting changes in the setting change history are designated, it becomes possible to return to the state before the designated plurality of setting changes at once. Furthermore, instead of analyzing the setting change from the key input history, it is possible to save the memory and speed up the processing by directly storing the setting change contents. It is possible to display it in a list and select it back freely, such as selecting the part of the setting you want to return or resetting to a specified location. Therefore, convenience can be improved.

  The electronic device 10 is an electronic device such as a mobile phone terminal, an electronic notebook, or a personal computer. Therefore, a configuration corresponding to each device is added to the configuration of FIG. For example, when the electronic device 10 is a mobile phone terminal, a communication function for performing wireless communication, a mail function, and the like are further provided. Of course, the electronic device 10 may be other than the above devices. In particular, the above processing is effective for the electronic device 10 to which a setting change key is assigned and the setting can be easily changed.

Embodiment 2. FIG.
In the present embodiment, the setting content is analyzed so that the setting can be returned to the state in which the setting has been used for a long time without change. Since the configuration other than this is the same as that of the first embodiment, the description thereof is omitted. For example, when there is no change over a certain time (for example, a long time such as one month) when the setting change date and time is found, it can be seen that the user has used the long time setting without change. The CPU 1 determines that this setting is a “user's convenience” setting. Specifically, referring to the setting change history, the setting with the longest usage time is extracted for each setting item. The setting with the longest usage time is registered as the recommended setting. In addition, the time between setting changes may be used time, and the accumulated time obtained by summing up each setting may be used time.

  When the setting return operation is performed as in step S21, the recommended setting icon 7 is displayed as shown in FIG. Here, the display unit 2 displays a recommended setting icon 7 on the display screen together with the setting change history table 6. When the user selects the recommendation setting icon 7, the CPU 1 returns to the recommendation setting. It is possible to return to the state that was used without changing the setting for a long time. When the recommended setting is specified, it is restored to the setting with the longest usage time.

  Note that this recommended setting may be stored in the change history. That is, the recommended setting may be stored in the storage unit 3. If a certain setting continues to be used without changing the setting for a long time, the recommended setting is updated. Thereby, the setting that has not been changed for a long time is added to the recommended setting. The recommended setting may be registered for each setting item. By doing in this way, a setting can be returned simply and appropriately, and operativity can be improved.

Other embodiments.
An electronic apparatus according to another embodiment will be described with reference to FIG. The electronic device 10 includes an input unit 11, a storage unit 12, a display unit 13, and a control unit 14. The input unit 11 has the same configuration as the operation unit 5 and accepts an input operation from the user. The storage unit 12 has the same configuration as the storage unit 3, and stores information before and after the setting change in association with the setting change time for the setting changed by the input operation of the input unit 11. The display unit 13 has the same configuration as that of the display unit 2 and displays information before and after the setting change stored in the storage unit as a setting change history together with the setting change time. The control unit 14 corresponds to the CPU 1, and when a setting change in the setting change history is designated by an input operation of the input unit 11, the control unit 14 returns to the state before the designated setting change.

  Note that the above control may be executed by a computer program. The control program described above can be stored using various types of non-transitory computer readable media and supplied to a computer.
