(Description of operation of embodiment)
Next, an example of the operation of the mobile phone terminal device shown in FIG. 1 will be described using the flowchart of FIG. FIG. 2 is a flowchart for explaining an example of the operation of the mobile phone terminal device shown in FIG.

  In the flowchart of FIG. 2, first, the power of the mobile phone terminal device is turned on by pressing the power key provided in the input unit 110 of FIG. Step S1). Thereafter, in response to pressing operations of various keys of the input unit 110 by the user of the mobile phone terminal device, various corresponding applications are activated (step S2). However, if the mobile phone terminal device is in a call state or data transmission / reception state, which is a basic function, it does not proceed to the next step S3 and maintains the call state or data transmission / reception state.

  Next, when there is an idle state that is not a call state or a data transmission / reception state, an abandonment monitoring timer that monitors a predetermined time as an abandonment monitoring time period is activated (step S3), and the activated application Measure elapsed time. It is confirmed whether or not the time measured by the activated monitoring timer has elapsed a predetermined time (step S4). If it has not elapsed (NO in step S4), the predetermined time has elapsed. In order to wait until it is completed, the confirmation operation in step S4 is repeated. If the predetermined time has elapsed (YES in step S4), the process proceeds to the next step S5.

  Proceeding to step S5, next, based on the acceleration information input from the acceleration sensor 105, whether or not there has been a change exceeding a predetermined value in the position of the mobile phone terminal device during a predetermined time period, That is, it is confirmed whether or not the mobile phone terminal device has moved (step S5). If the mobile phone terminal device has moved (YES in step S5), the abandonment monitoring timer is reset, and then the mobile phone terminal device is moved again. In order to monitor the neglected state of the telephone terminal device, the process returns to step S3. On the other hand, if the mobile phone terminal device has not moved (NO in step S5), the process proceeds to the next step S6.

  In step S5, next, based on the illuminance information input from the illuminance sensor 104, the ambient illuminance of the mobile phone terminal device is brightened by the liquid crystal display device of the display unit 111, and the in-use state. It is confirmed whether or not a predetermined illuminance (here, the constant illuminance is expressed as “α”) exceeds a predetermined illuminance (step S6). If the ambient illuminance of the mobile phone terminal device exceeds a certain illuminance “α” (YES in step S6), after resetting the timer for leaving monitoring, in order to monitor the leaving state of the mobile phone terminal device again, The process returns to step S3. On the other hand, when the ambient illuminance of the mobile phone terminal device is less than or equal to the constant illuminance “α” (NO in step S6), the user of the mobile phone terminal device uses the mobile phone terminal device for a predetermined time. If it is determined that the application that has been started is in a sleep state or the user has abandoned viewing the screen, the process proceeds to the next step S7.

  In step S7, since the user of the mobile phone terminal device is not using the mobile phone terminal device, the activated application is terminated (step S7). Further, the power supply control unit 113 controls the power supply control unit 113 to switch to the power saving mode, and stops the power supply to at least the display unit 111 with high power consumption among the parts of the mobile phone terminal device. By performing control such as turning off or turning off the backlight, the operation state portion is set to the minimum necessary by sequentially shifting from a portion with large power consumption to a sleep state (step S8).

(Description of operation of other embodiment)
Next, an example different from the flowchart of FIG. 2 of the operation of the mobile phone terminal device shown in FIG. 1 will be described using the flowchart of FIG. FIG. 3 is a flowchart for explaining an example of the operation of the mobile phone terminal device shown in FIG. 1 different from FIG. In the flowchart of FIG. 3, the operations (steps S <b> 1 to S <b> 5) from when the mobile phone terminal device is turned on and the main body is activated until the mobile phone terminal device is confirmed to be moved by the acceleration sensor 105 are shown in FIG. 2 is exactly the same as the operation of steps S1 to S5 shown in FIG. 2, and is expressed using the same step codes as in FIG. If “NO” is determined in step S5, the subsequent operation is different from the flowchart in FIG. 2, and the process proceeds to step S16 in FIG. 3 as the next step.

  That is, in the flowchart of FIG. 3, when the movement of the mobile phone terminal device is not detected for a certain time measured by the abandonment monitoring timer (NO in step S5), the mobile phone terminal device Unlike the determination operation using the illuminance sensor 104 in the flowchart of FIG. 2, the operation for determining whether or not the user is using the mobile phone terminal device is being activated for the user of the mobile phone terminal device In this example, it is determined whether or not to continue the operation state of the mobile phone terminal device by inquiring whether or not the application can be terminated.

  That is, if no movement is detected in the cellular phone terminal device in step S5 (NO in step S5), the process proceeds to the next step S16, and a message indicating whether or not to agree to terminate the running application. Is displayed on the display unit 111 to inquire the user of the mobile phone terminal device (step S16). When the user of the mobile phone terminal device who has seen the inquiry on the display unit 111 instructs the input unit 110 that the running application is not terminated (NO in step S16), after resetting the neglect monitoring timer, Again, the process returns to step S3 in order to monitor the leaving state of the mobile phone terminal device. On the other hand, when the user of the mobile phone terminal device instructs the end of the running application from the input unit 110 (YES in step S16), the process proceeds to the next step S17.

  If it progresses to step S17, since the user of the mobile telephone terminal device has instruct | indicated completion | finish of the application currently started, it will terminate the said application that was started (step S17). Further, the power supply control unit 113 controls the power supply control unit 113 to switch to the power saving mode, and stops the power supply to at least the display unit 111 with high power consumption among the parts of the mobile phone terminal device. By performing control such as turning off or turning off the backlight, the region where the power consumption is large is sequentially shifted to the sleep state, and the region in the operating state is set to the minimum necessary (step S18).

  By performing the operations as shown in FIGS. 2 and 3 above, the power consumption of the mobile phone terminal device can be effectively reduced while maintaining the operability of the user.

  In the flowcharts of FIGS. 2 and 3, whether or not the movement of the mobile phone terminal device has been detected during the predetermined time measured by the abandonment monitoring timer using the acceleration sensor 105 in step S5. However, instead of the determination by the acceleration sensor 105, the input data from the input unit 110 for inputting the user's operation information exists for a certain period of time counted by the neglect monitoring timer. It may be determined whether or not there is. Alternatively, in step S5, not only the presence / absence of movement by the acceleration sensor 105 but also the presence / absence of input data from the input unit 110 is determined so that the user of the mobile phone terminal device can It may be determined whether or not the user is operating.

  Alternatively, in some cases, the process of step S5 is omitted, that is, whether or not there is a movement by the acceleration sensor 105 and the input data from the input unit 110 is determined during a certain time measured by the neglect monitoring timer. The use state of the user may be determined only by determining the ambient illuminance by the illuminance sensor 104 or inquiring the user whether the application can be terminated or not. As described above, when the process of step S5 is omitted, in order to more reliably determine whether or not the user of the mobile phone terminal device is used, the peripheral illuminance is determined as a result of the peripheral illuminance determination by the illuminance sensor 104. When the illumination intensity has decreased to a predetermined constant illuminance “α” or less, an inquiry about whether or not the application can be terminated is made to the user, and the determination of the ambient illuminance by the illuminance sensor 104 and whether or not the application can be terminated to the user. You may make it use together with an inquiry.

(Explanation of effect of embodiment)
As described above, according to the embodiment of the present invention, the following effects can be obtained.

  The first effect is that unnecessary power consumption can be suppressed while maintaining the operability of the user of the mobile phone terminal device. The reason is that not only the mobile phone terminal device is moved by the acceleration sensor 105 but also the ambient light intensity of the mobile phone terminal device by the illuminance sensor 104 or an inquiry to the user of the mobile phone terminal device. This is because the mode can be shifted to the power saving mode based on the result of the presence / absence determination.

  The second effect is that power consumption can be suppressed based on the user's intention. The reason is that, as described above, it is possible to shift to the power saving mode based on the result of determining the user's intention by the inquiry to the user of the mobile phone terminal device.
