<Case 1>
When the display unit (5) is a liquid crystal display (LCD) or the like, the control unit (6) controls the display unit (5) so as to reduce the illuminance for the backlight. In the case of the display unit (5) capable of controlling the illuminance in several steps, the control unit (6) is for watching the program broadcast until the end time because the remaining power measured by the terminal state control unit (1).

When it is determined that there is no such information, the control unit (6) displays a warning or the like on the display unit (5) to notify that viewing up to the end time of the program broadcast to be viewed is impossible.

  As described above, the communication terminal device according to the present embodiment determines whether or not the remaining power level measured by the terminal state control unit (1) satisfies the power amount necessary for viewing the program broadcast until the end time. When it is determined that the remaining amount of power measured by the terminal state control unit (1) does not satisfy the amount of power necessary for viewing the program broadcast until the end time, the program broadcast to be viewed ends. The power of the communication terminal device is suppressed so that viewing up to the time is possible.

(Second Embodiment)
Next, a second embodiment will be described.

  The communication terminal device according to the second embodiment allows the remaining amount of power measured by the terminal state control unit (1) to view the program broadcast on which the viewing operation has been performed until the end time even if the power of the communication terminal device is suppressed. When it is determined that the amount of power necessary for this is not satisfied, the remaining amount of power measured by the terminal state control unit (1) is the amount of power necessary for recording the program broadcast on which the viewing operation has been performed until the end time. Is determined, and it is determined that the remaining amount of power measured by the terminal state control unit (1) satisfies the amount of power necessary for recording the program broadcast on which the viewing operation has been performed until the end time. In such a case, a recording process of a program broadcast for which a viewing operation has been performed is performed.

  As a result, even if the power of the communication terminal device is suppressed, the remaining power measured by the terminal state control unit (1) satisfies the amount of power necessary for viewing the program broadcast on which the viewing operation has been performed until the end time. Even if the program broadcast is not performed, it is possible to perform the recording process of the program broadcast for which the viewing operation has been performed, and the program broadcast subjected to the recording process can be viewed later. Hereinafter, the communication terminal apparatus according to the second embodiment will be described in detail with reference to FIG.

<Power control method in communication terminal device>
First, the power control of the communication terminal device in the second embodiment will be described with reference to FIG.

  The power control of the communication terminal apparatus in the second embodiment performs almost the same power control as the process up to step S15 of the communication terminal apparatus in the first embodiment, and the following processes are different.

  The control unit (6) displays a warning or the like on the display unit (5) and notifies that the viewing is not possible until the end time of the program broadcast to be viewed (step 15), and then the terminal state control unit It is determined whether or not the remaining amount of power measured in (1) satisfies the amount of power necessary for recording the program broadcast on which the viewing operation has been performed until the end time (step S20).

(Step S20 / insufficiency), the process ends (step S16).

  In addition, the control unit (6) determines that the remaining amount of power measured by the terminal state control unit (1) satisfies the amount of power necessary for recording the program broadcast on which the viewing operation has been performed until the end time. In this case (step S20 / no problem), the control unit (6) displays on the display unit (5) whether or not to record the program broadcast to be viewed, and inquires the operator about the recording process. Is performed (step S21).

  When the control unit (6) determines that there is no recording process request for the program broadcast to be viewed (step S22 / none), the process ends (step S16).

  When the control unit (6) determines that there is a recording process request for the program broadcast to be viewed (step S22 / Yes), the control unit (6) performs the recording process for the program broadcast to be viewed. Control is performed (steps S23 and S24). Then, when the program broadcast recording process ends, the process ends (step S16). In FIG. 6, the program broadcast is recorded in the external storage unit (9). However, the program broadcast can be recorded in the storage unit (8).

  Thus, even if the communication terminal device in the second embodiment performs power suppression of the communication terminal device, the remaining power measured by the terminal state control unit (1) terminates the program broadcast in which the viewing operation is performed. If it is determined that the amount of power necessary for viewing up to the time is not satisfied, the remaining amount of power measured by the terminal state control unit (1) is used to record the program broadcast on which the viewing operation has been performed until the end time. It is determined whether or not the necessary amount of power is satisfied, and the remaining amount of power measured by the terminal state control unit (1) satisfies the amount of power necessary for recording the program broadcast on which the viewing operation has been performed until the end time. If it is determined that the program broadcast is performed, the program broadcast is recorded.

  As a result, even if the power of the communication terminal device is suppressed, the remaining power measured by the terminal state control unit (1) satisfies the amount of power necessary for viewing the program broadcast on which the viewing operation has been performed until the end time. Even if the program broadcast is not performed, it is possible to perform the recording process of the program broadcast for which the viewing operation has been performed, and the program broadcast subjected to the recording process can be viewed later.

  In the process of FIG. 6 described above, it is determined that the remaining power level measured by the terminal state control unit (1) satisfies the power amount necessary for recording the program broadcast on which the viewing operation has been performed until the end time. If so (step S20 / no problem), the recording process is inquired (step S21), and if it is determined that there is a recording process request for the program broadcast to be viewed (step S22 / Yes), it becomes the viewing target. The program broadcast control process is decided to be performed (steps S23 and S24). However, the process of steps S21 and S22 shown in FIG. 6 is omitted, and the terminal state control unit (1) as shown in FIG. When it is determined that the remaining amount of power measured satisfies the amount of power necessary to record the program broadcast for which the viewing operation has been performed until the end time (step S30 / no problem), the program to be viewed is released. It is also possible to control the recording process of the to automatically (step S31 and S32). As a result, the communication terminal device can be configured to automatically perform the recording process.
