[First Embodiment]
FIG. 1 is a block diagram showing the configuration of the mobile phone device according to the first embodiment of the present invention.
The cellular phone device 100 according to the present embodiment includes a telephone execution unit 120 that performs telephone communication, a broadcast viewing execution unit 130 that receives broadcast radio waves and outputs broadcast data included in the broadcast radio waves so as to be viewable, The power supply unit 110 includes a battery 110a that supplies power to them, and a control unit 140 that restricts the operation of the broadcast viewing execution unit in a stepwise manner based on power supply state data relating to the state of the battery.

The control method for limiting the operation of the broadcast viewing execution unit in the mobile phone device according to the present embodiment is as follows.
First, the control unit 140 acquires power supply state data (S11), and selectively restricts the operation of the broadcast viewing execution unit based on the power supply state data (S12). That is, if it is determined from the power state data that the remaining battery level is low, an operation to be restricted is selected from the plurality of operations of the broadcast viewing execution unit 130, and the selected operation is restricted. Here, as a limiting method, it is conceivable to stop the operation or suppress the output of the operation.
By repeating such an operation, the broadcast viewing operation of the mobile phone device 100 is limited in stages according to the power state data.

  Therefore, according to the mobile phone device according to the present embodiment, the operation of the broadcast viewing execution unit is limited step by step according to the power state data, so that broadcast radio waves can be received while securing the power necessary for the telephone function. Thus, the display / playback time of the broadcast data output, that is, the operation time of the TV viewing function can be extended. In addition, by controlling each operation of the display unit, audio output unit, and broadcast radio wave reception unit in stages, the user will not be interrupted suddenly from watching the TV, and the user can smoothly watch TV It is possible to notify the operation restriction.

[Second Embodiment]
FIG. 3 is a block diagram showing the configuration of the mobile phone device according to the second embodiment of the present invention.
As shown in FIG. 3, mobile phone device 200 according to the present embodiment includes power supply section 110, telephone execution section 120, broadcast viewing execution section 230, and control section 206.
The power supply unit 110 and the telephone execution unit 120 of the mobile phone device 200 according to the present embodiment have the same configurations and functions as the power supply unit 110 and the telephone execution unit 120 of the mobile phone device 100 described in the first embodiment. Therefore, the same reference numerals are used here and the description thereof is omitted.

The broadcast viewing execution unit 230 includes a broadcast radio wave reception unit 231, a display unit 232, and an audio output unit 233.
When the television viewing function is operated in the mobile phone device 200, the broadcast radio wave receiving unit 231 receives broadcast radio waves such as one seg and outputs broadcast data included in the broadcast radio waves.
The display unit 232 displays video data and character data among the broadcast data output from the broadcast radio wave reception unit 231, and the audio output unit 233 outputs audio data of the broadcast data and reproduces audio and music.
The control unit 240 periodically acquires power state data indicating the state of the power source unit 101 and outputs the data, and based on the power state data, the display unit 232 of the broadcast viewing execution unit 230, the audio output The operation of the unit 233 and the broadcast wave reception unit 231 is controlled stepwise.

  Note that these components include hardware of a computer (not shown) mounted on the mobile phone device 100 by installing a computer program in a computer having a CPU (Central Processing Unit), a memory, and an interface. Hardware resources and software are realized in cooperation.

Next, the operation of the mobile phone device 200 in the present embodiment will be described with reference to the flowchart of FIG.
The control unit 240 acquires power state data regarding the state of the power unit 110 and stores it in a storage device of the mobile phone device 200 (not shown) (S21). The power supply state data is information regarding the state of the power supply necessary for the mobile phone device 200 to operate. For example, the power supply state data includes a value indicating the power supply voltage supplied to the mobile phone device 200 by the battery 110a of the power supply unit 110. It may be included data.

  Subsequently, based on a predetermined condition, the control unit 240 determines whether or not to limit broadcast data output in the TV viewing function of the mobile phone device 200 from the power state data stored in the storage device of the mobile phone device 200 (not shown). The output restriction is set by controlling the operations of the display unit 232, the audio output unit 233, and the broadcast radio wave receiving unit 231 (S22).

  Here, the broadcast data output restriction will be described. When it is determined from the power status data acquired by the control unit 240 that the power supply voltage of the battery 110a is sufficiently high and the remaining battery level does not affect the telephone function even if the TV viewing operation is performed, the normal TV viewing operation is performed. The broadcast data output restriction control is not performed, but when it is determined that the power supply voltage of the battery 110a is not sufficiently high and the remaining amount of the battery is low, the display unit is set according to the level of the power supply voltage value. These operations are controlled for the H.232, the audio output unit 233, and the broadcast radio wave reception unit 231 to set broadcast data output restrictions. For example, when the power supply voltage of the battery 110a is at a predetermined level, control is performed such that the display data output to the display unit 232 is “output only character data”, and when the voltage is lower than the predetermined level, Control is added to reduce the volume level of audio data to be output not only to the display unit 232 but also to the audio output unit 233 by 50%. Furthermore, when it can be determined that the power supply voltage level is sufficiently low, control is performed to stop the operation of the broadcast viewing execution unit 230 by stopping the power supply to the display unit 232, the audio output unit 233, and the broadcast radio wave reception unit 231. Limit broadcast data output.

When the predetermined time has elapsed (S23), the control unit 240 again acquires the power state data and executes the above-described operation (S21 to S22).
For example, when the broadcast data output restriction on the display unit 232 is set to “output only character data”, the broadcast data output restriction on the display unit 232 is determined from the power state data acquired by the control unit 240 after a predetermined time has elapsed. If the control unit 240 determines that the level of the operation of the telephone execution unit 120 is hindered with the setting of “output only character data”, the broadcast data output restriction on the display unit 232 is set to “power supply stop”. Then, the display function of the display unit 232 in the TV viewing operation is stopped, and the broadcast data output restriction control for only the audio output by the audio output unit 233 is performed.

  As described above, the cellular phone device according to the present embodiment suddenly stops the TV viewing function by periodically acquiring the power state data and performing the broadcast data output restriction control based on the power state data. Without restricting the TV viewing function step by step, it is possible to extend the operable time of the device itself.

[Third Embodiment]
FIG. 5 is a block diagram showing a configuration of a cellular phone device according to the third embodiment of the present invention.
As shown in FIG. 5, mobile phone device 300 according to the present embodiment includes power supply unit 110, telephone execution unit 120, broadcast viewing execution unit 230, control unit 340, storage unit 340a, and broadcast data display. The restriction release unit 350 and the release button 360 are configured.
The power supply unit 110, the phone execution unit 120, and the broadcast viewing execution unit 230 of the mobile phone device 300 according to the present embodiment are the same as the power supply unit 110, the phone execution unit 120, and the mobile phone device 200 described in the second embodiment. Since it has the same configuration and function as the broadcast viewing execution unit 230, the same reference numerals are used here, and description thereof is omitted.

The control unit 340 periodically acquires power state data indicating the state of the power unit 110 and outputs the data, and restricts the operation of the broadcast viewing execution unit 230 in stages based on the power state data. Set broadcast data output limit. When the broadcast data output restriction operation is performed based on the power state data, when the control unit 340 receives the restriction release signal output from the broadcast data output restriction release unit 350, the restriction state of the broadcast viewing execution unit 230 is received. The output restriction is temporarily released according to
The broadcast data display restriction release unit 350, when the output of broadcast data is restricted by the control unit 340, can be canceled by the user if the release button 360 is a user's explicit operation, for example, a push button type. By pressing the button 360, a request for canceling the output restriction is made, and a restriction release signal is output to the control unit 340.

  These components are installed in a computer (not shown) installed in the mobile phone device 300 by installing a computer program in a computer having a CPU (Central Processing Unit), a memory, and an interface. Hardware resources and software are realized in cooperation with each other.

  Next, the operation of the cellular phone device 300 according to the present embodiment will be described with reference to the flowchart shown in FIG.

The control unit 340 acquires power state data relating to the state of the power unit 110, stores it in the storage unit 340a of the mobile phone device 300 (S31), and sets a state level from this power state data (S32).
As described in the second embodiment, the power status data is information regarding the power status necessary for the mobile phone device 300 to operate. The data may include information indicating the output voltage value of the battery 110a and data including charging state information indicating whether or not the battery 110a is being charged.
The state level is a condition for controlling the broadcast data output restriction in the mobile phone device 300 in stages, and the level is set according to the power state data.

Here, an example of the relationship between the acquired power supply state data and the state level is shown in FIG. FIG. 7 shows the output voltage of the battery 110a read from the power supply state data on the vertical axis and the elapsed time on the horizontal axis, and the period when the control unit 340 acquires the power supply data is shown as [T]. Here, the state level is classified into “level 1” to “level 5” from the higher output voltage of the battery 110a.
For example, the control unit 340 sets the state level to “level 1” from the output voltage value information of the battery 110a included in the power supply state data acquired by the control unit 340 at time 1T. Further, when the battery 110a is being charged based on the charge state information included in the power state data, a condition may be added such that the state level is set to “level 1” regardless of the output voltage value of the battery 110a. good.

Next, the control unit 340 performs broadcast data output restriction control according to the set state level (S33).
The broadcast data output restriction control is performed by restricting the operations of the display unit 232, the audio output unit 233, and the broadcast radio wave reception unit 231 of the broadcast viewing execution unit 230 in accordance with the state level of the mobile phone device 300. This is to control the power consumption of the apparatus 300. At this time, it is desirable to limit the operation with large power consumption. For example, today's multifunctional mobile phone devices tend to increase the screen size of LCD (Liquid Crystal Display) used in the display unit due to their multifunctionality, and use this LCD with the maximum brightness setting. In view of the fact that about half of the total power consumption of the mobile phone device is consumed for the display of the LCD, the power consumption of the mobile phone device is controlled by restricting the display of the LCD. be able to.
Therefore, regarding the display operation control of the display unit 232, the brightness of the display device used in the display unit 232 and the format of the data being output are changed from the one with large power consumption to the one with small power consumption, and further the control such as stopping. Power consumption can be controlled by performing
Similarly, for the audio output unit 233 and the broadcast wave reception unit 231, the power consumption of the mobile phone device 300 can be controlled by restricting these operations individually or simultaneously.

Here, an example of the broadcast data output restriction control according to the above-described state level is shown in FIG. FIG. 8 is a broadcast data output restriction control table storing operation control information of the display unit 232, the audio output unit 233, and the broadcast radio wave receiving unit 231 according to the state level shown in FIG. This table is stored in the part 340a. The control unit 340 performs broadcast data output restriction control according to this table, and controls the power consumption of the mobile phone device 300.
For example, if the state level set by the control unit 340 is “level 2”, the control unit 340 displays the broadcast data by reducing the luminance of the display unit 232 by 50% from the broadcast data output restriction control table. The display unit 232 is controlled to set an output limit. If it is “level 3”, the control unit 340 sets the broadcast data to be displayed on the display unit 232 to only character data, reduces the volume of the audio data output from the audio output unit 233 by 30%, and outputs the broadcast data. Set limits. If it is “level 5”, the control unit 340 stops the power supply to the display unit 232, the audio output unit 233, and the broadcast radio wave reception unit 231 as broadcast data output restriction control, and Stop watching TV.

Next, the control unit 340 determines whether an output restriction release signal has been received from the broadcast data output restriction release unit 350 (S34).
When the control unit 340 has not received the output restriction release signal (“NO” in S34), the control unit 340 waits until the period [T] for acquiring the power state data elapses (S37).

On the other hand, the broadcast data output restriction release unit 350 outputs an output restriction release signal to the control unit 340 when detecting an explicit operation of the release button 360 by the user.
When the control unit 340 receives the output control release signal (“YES” in S34), the control unit 340 temporarily releases the broadcast data output restriction control (S35).

  Here, releasing the broadcast data output restriction control is to return all the TV viewing functions of the mobile phone device 300 to the normal operation state. For example, when the state level of the cellular phone device 300 is “level 3”, the broadcast data output restriction control is based on the table shown in FIG. In contrast, output restriction control is performed such that the sound volume is reduced by 30%. Canceling this output restriction control means that the display unit 232 and the audio output unit 233 are returned to the normal operation and the broadcast data is normally output.

After a preset time elapses after the broadcast data output restriction control is temporarily released by the control unit 340, the control unit 340 displays the broadcast data corresponding to the set state level of the mobile phone device 300. The output restriction control is performed again (S36).
When the cycle [T] for acquiring the power state data elapses (S37), the control unit 340 acquires the power state data again and executes the above-described operation (S32 to S36).

As described above, the cellular phone device according to the present embodiment periodically obtains power state data and performs broadcast data output restriction control according to the power state data, thereby performing step-by-step broadcast data output restriction. Control can be performed, and the operable time of the television viewing function can be extended without causing the user to feel inconvenience such as sudden display restrictions. In addition, by extending the operable time of the television viewing function, it is possible to extend the incoming call waiting time for voice communication while the television viewing function is operating.
Furthermore, by providing a function for canceling the broadcast data output restriction, it is possible to temporarily confirm the content of the broadcast data in an unrestricted state even in a mobile phone device that is subjected to output restriction control. It is possible to flexibly limit broadcast data output to the user.

  It can be used for a mobile phone device having a TV viewing function.
