Description

  The present invention relates to a mobile terminal device such as a mobile phone.

  In recent years, mobile phones have high convenience due to their portability and multi-functionality, and are widely used as personal communication tools.

  Such a cellular phone has a built-in clock function, and the standby screen can display a clock in a digital format or an analog format. In some digital clock displays, the font size and design can be selected.

Patent Document 1 proposes a mobile phone that presses a time display key to extinguish the time display during the time display and displays the time when the time is not displayed.
JP 2002-94615 A

  However, when an image or animation is set on the standby screen, the clock display becomes an obstacle, and the user may select a small clock display or turn off the clock display. In this way, when the clock display is reduced or turned off, when it is desired to actually check the time, it is difficult to see the display with the small display, and a complicated operation is required for enlargement. In addition, the ON and OFF operations are complicated even when they are OFF. In particular, when the cellular phone is used as a table clock during nighttime sleep, the problem becomes noticeable in the state of sleepiness such as at night or in the morning.

  The present invention has been made in such a background, and it is possible to make it easy to see the clock display when necessary without requiring a complicated operation by the user and to prevent the clock display from getting in the way when unnecessary. A mobile terminal device is to be provided.

  A portable terminal device according to the present invention measures at least a display unit that displays a first screen and a second screen, a detection unit that detects occurrence of a predetermined trigger, and an elapsed time from the occurrence point of the predetermined trigger. When the occurrence of the predetermined trigger is detected in the state where the measurement means and at least the first screen are displayed, the condition is that the elapsed time from the previous trigger occurrence time exceeds the predetermined time And a control means for performing a control for temporarily displaying the second screen on the display unit.

  The “predetermined trigger” includes a user operation that can be detected by the mobile terminal. If the next predetermined trigger does not occur before the predetermined time elapses after the predetermined trigger is generated, the second screen is temporarily displayed when the next predetermined trigger is generated. This prevents the second screen from being displayed more frequently than necessary each time a predetermined trigger occurs.

  Another portable terminal device according to the present invention includes a display unit that displays at least a first screen and a second screen, a detection unit that detects occurrence of a predetermined trigger, and an elapsed time since the occurrence of the predetermined trigger. The first measuring means for measuring the state, and when the state in which the predetermined trigger is not generated exceeds the threshold time, the display unit is shifted to the power saving state, and the predetermined trigger is generated after the transition to the power saving state In a state where the power saving means for returning from the power saving state at the time, the second measuring means for measuring the elapsed time from the time when the display unit shifts to the power saving state, at least the first screen is displayed, When the predetermined trigger occurs in the power saving state, the second screen is temporarily displayed on the display unit on the condition that the elapsed time after the transition to the power saving state exceeds a predetermined time Characterized in that a control means for controlling that.

  In this portable terminal device, the condition for displaying the second screen is determined based on the elapsed time after shifting to the power saving state.

  The screen display method and program according to the present invention include a step of detecting the occurrence of a predetermined trigger, a step of measuring an elapsed time from the time of occurrence of the predetermined trigger, and a state in which at least the first screen is displayed When the occurrence of the predetermined trigger is detected, the step of checking whether or not the elapsed time from the previous trigger occurrence time exceeds the predetermined time, and the elapsed time from the previous trigger occurrence time to the predetermined time When it is determined that the second screen is exceeded, the step of displaying the second screen on the display unit, and the step of automatically returning the second screen to the display of the first display screen after displaying the second screen for a predetermined time; It is provided with.

  In another screen display method and program according to the present invention, a step of detecting occurrence of a predetermined trigger, a step of measuring an elapsed time from the time of occurrence of the predetermined trigger, and at least the first screen are displayed. In a state where the predetermined trigger does not occur and the state where the predetermined trigger does not occur exceeds the threshold time, the step of shifting the display unit to the power saving state and the elapsed time from the time when the display unit shifts to the power saving state are measured. And when at least the first screen is displayed and the predetermined trigger is generated in the power saving state, whether or not an elapsed time after shifting to the power saving state exceeds a predetermined time. The second screen is displayed on the display unit on condition that the checking step and the elapsed time after shifting to the power saving state exceed a predetermined time A step that, characterized by comprising a step of returning to the display automatically the first display screen the second screen after a certain time display.

  According to the present invention, the first screen is normally displayed, and the second screen (for example, a big clock display screen) is temporarily displayed only when necessary, so that the second screen becomes an obstacle. Therefore, the first screen can be used effectively. In addition, since the second screen is displayed by a predetermined trigger on the condition that a certain amount of time has elapsed, the troublesomeness that occurs each time the predetermined trigger occurs is eliminated.

  In addition, since the determination for displaying the second screen is automatically performed and the screen is automatically returned to the first screen after being displayed, no complicated operation by the user is required.

  FIG. 2 shows changes in the display screen 200 related to the clock display in the present embodiment. In the case of a portable terminal having a main display unit and a sub display unit, this display screen 200 may be a display screen of any display unit. FIG. 2A shows a standby screen as the first screen (usually the other side) of the mobile terminal. The display screen 200 includes a picto area 210 as a first display area including an icon indicating a received radio wave state, an icon indicating a remaining battery level, a small digital time display, and the like, and a main display area as a second display area. 220. In the first screen of FIG. 2A, a so-called standby screen is displayed in the main display area 220. The display content displayed on the standby screen can be selected by the user such as a selected image or calendar.

  FIG. 2B shows an example in which a large clock display 221 in digital format is performed on the main display area 220. FIG. 2C shows an example in which an analog large clock display 222 is performed in the main display area 220. The display design in a large size makes the display design as easy to understand as possible.

  In the normal state, the standby screen of FIG. 2 (a) is displayed, and when a predetermined trigger is generated under a predetermined condition, the second screen as shown in FIG. 2 (b) or FIG. 2 (c) is displayed. Is temporarily displayed. After the display of the second screen, the display automatically returns to the original first screen after a predetermined short time T (for example, 1 to several seconds). This short time T may be a predetermined fixed time, or may be selected or designated by the user. Whether the digital format clock or the analog format clock is displayed as the second screen may be fixed in advance by the mobile terminal, or the user may select either You may make it selectable.

  Examples of the “predetermined trigger” include operation of the operation unit 17 by the user, generation of detection outputs of various sensors 21 including the above-described open / close sensor, and particularly detection of opening of the case of the folding portable terminal. Can be mentioned. However, the present invention is not limited to these, and any event that can be detected by the mobile terminal can be used as a trigger.

  If the second screen is displayed every time a predetermined trigger occurs, it is expected that the user may feel troublesome. In general, it is considered that a predetermined trigger can be generated more frequently than the expected clock check frequency.

  Therefore, in the present embodiment, as shown in FIG. 3, when a trigger is generated after a predetermined time N minutes (for example, 10 minutes) continues for a period in which no trigger is generated, In response, the second screen is displayed for the short time T described above. Here, N does not necessarily have to be a positive number, and need not be “10”. The value of N may be a fixed value or may be set by the user.

  FIG. 4 is a flowchart showing an example of a processing procedure of the control unit for realizing such an operation. This process is realized by the control unit 11 shown in FIG.

  First, after the portable terminal is turned on, the control unit 11 displays a first screen as shown in FIG. 2A on the display unit (S11). At this time, a timer is started (S12). This timer is for measuring the predetermined time (N minutes). If no trigger is generated during the predetermined time (S13, Yes), the process proceeds to the next step S14. If the trigger occurs before the predetermined time has elapsed, the process returns to step S12, initializes the timer, and starts again (S12). In this case, even if a predetermined trigger occurs, the display of the second screen is suppressed.

  In step S14, when a predetermined trigger occurs (S14, Yes), the second screen is displayed for a predetermined short time T (S15). Thereafter, the process automatically proceeds to step S11 and returns to the display of the first screen (S11).

  Note that the “predetermined trigger” in step S13 and step S14 is not necessarily the same. For example, the predetermined trigger in step S13 may include any user operation on the mobile terminal, and step S14 may be limited to a user specific operation.

  Next, a second embodiment of the present invention will be described. The configuration of the portable terminal is as shown in FIG. In this embodiment, the second screen is displayed in association with turning off / on the backlight. In a portable terminal using a liquid crystal display with a backlight as the display unit 18 (FIG. 1), the backlight is turned off when there is no user operation for a predetermined time or more as a power saving mode in order to save battery power consumption. Then, an operation of turning on again when a user operation is performed is performed. Normally, the predetermined time can be specified by the user.

  When the backlight is turned off, the user has not operated the mobile terminal for a predetermined time or more. When the backlight is turned on, any operation that causes the backlight to turn on, such as a user operation, is performed. Means that has occurred. In the present embodiment, the second screen is temporarily displayed using the backlight lighting timing. (This second screen is the same as that in the first embodiment.) However, if the second screen is displayed every time the backlight is turned on, it may be troublesome for the user.

  Therefore, as shown in FIG. 5, in this embodiment, the backlight turn-off time is measured, and only when the time exceeds a predetermined time, the second time is temporarily turned on at the next backlight turn-on time. Display the screen. As described above, the user operation after the relatively long period of no user operation has passed is relatively likely that the user is trying to check the time. Since it does not occur frequently, even if the second screen is temporarily displayed regardless of the user's intention, it is considered that no annoyance is felt.

  FIG. 6 is a flowchart showing an example of a processing procedure of the control unit 11 for realizing the operation of the second embodiment.

  When the portable terminal is turned on, the control unit 11 turns on the backlight of the display unit 18 (S21). Further, the first screen is displayed (S22). The first screen is the same as described in the first embodiment. Along with the display of the first screen, the first timer is started (S23). The set time of the first timer is a threshold time for turning off the backlight and shifting to the power saving state when there is no user operation for this time or longer. As described above, the user can set the threshold time to an arbitrary time up to, for example, about 30 seconds. If a predetermined trigger occurs (S25, Yes) by the time the threshold time elapses (S25, Yes), the process returns to step S23, initializes the first timer, and starts again (S23).

  When the first timer has passed the threshold time (S24, Yes), the backlight is turned off (S26) and the second timer is started (S27). This second timer is for monitoring the passage of the aforementioned predetermined time N minutes. Then, it waits for a predetermined trigger to occur (S27). When a predetermined trigger occurs, the backlight is turned on (S29). Also, the measured value of the second timer at this time is checked. If the measured value of the second timer exceeds the predetermined time (N minutes) (S30, Yes), the second screen is displayed for a predetermined short time T (S31), and then the process returns to step S22.

  If the predetermined time (N minutes) has not elapsed in step S30, the process returns to step S22.

  By such processing, the operation of the second embodiment is realized.

  The operation of the second embodiment is based on the premise that the backlight is turned off in the power saving mode in the liquid crystal display with backlight, but the present invention is not limited to the liquid crystal display with backlight. For example, when a display device that lowers the display brightness in the power saving mode is used, the decrease in the brightness corresponds to turning off the backlight.

  FIG. 7 shows an example of a setting screen for explaining a modification of the present invention. In the above description, the condition for shifting to the second screen is not related to the time zone within one day. However, there may be a case where the user desires to display the temporary second screen of the present invention only at night and does not desire such display at daytime. In such a case, the user can be set to suppress (or permit) the display of the second screen in a specific time zone. In the example of the setting screen of FIG. 7, it can be selectively set to suppress temporary “large clock display” during the daytime. This setting content is stored in the storage unit 15 in a nonvolatile manner, and it is determined whether to enable or disable the processing based on which time zone the current time belongs in the above processing. Note that the daytime time zone in FIG. 7 may be fixed in advance, or may be set from what time to what time on a different setting screen (not shown).

  FIG. 8 shows an example of a setting screen for explaining another modified example of the present invention. In the first modification described with reference to FIG. 7, the second screen display is suppressed (or permitted) according to the current position of the mobile terminal, not based on the time zone. For example, this modification can be used for the purpose of enabling this function only at the user's home. In the example of the setting screen of FIG. 8, the setting can be made by the user responding “Yes” or “No” to the question “Do you want to display the big clock only at the current location?” It has become. When the user's answer is “Yes”, the place where this setting is performed is detected and stored in the storage unit 15 together with the user selection contents in a non-volatile manner. Thereafter, the mobile terminal periodically monitors the current position of the mobile terminal using the GPS receiving unit 20 (FIG. 1), and the current position is in the stored position (or in the vicinity of the position). Is detected, the transition to the display of the second screen based on the predetermined trigger under the predetermined condition described above is validated.

  The second modification can be used in combination with the first modification.

  The preferred embodiments of the present invention have been described above, but various modifications and changes other than those mentioned above can be made.

  For example, on the second screen, in addition to displaying the time, the date (and day of the week) may also be displayed. Further, the second screen is not limited to the clock display.

  In the power saving state, the backlight is turned off, but the luminance may be lowered.

  In the above example, once the second screen is displayed, if the predetermined time does not elapse thereafter, the second screen will not be displayed even if a predetermined trigger occurs. When it is desired to display the second screen again before the lapse of time, an operation button or menu as a means for forcibly displaying a large clock, or a predetermined operation method (for example, a predetermined trigger is continuously performed in a short time). Etc.) may be provided.

  Although only the standby screen has been described as the first screen, the first screen may include a screen other than the standby screen.
