Description

  The present invention relates to a mobile phone, a program, and an information storage medium having a television broadcast receiving function.

  In a mobile phone having a TV broadcast receiving function, the amount of power consumed when watching TV is a problem. When the power consumption during TV viewing is large, a mobile phone that is premised on battery driving has a problem that the standby time and the callable time are shortened.

  As a technique for reducing the power consumption during TV viewing, for example, a technique for stopping functions other than the TV viewing function (including image display and audio output) of the mobile phone during TV viewing can be considered. However, in this method, the call function, which is the original function of the mobile phone, cannot be used at all while watching TV.

  For example, when the wireless communication function is stopped, the mobile phone is in a state similar to a state in which the mobile phone is not turned on or in a place where the mobile phone does not reach radio waves. While not trying to make a call to the mobile phone in such a state, an announcement that the caller cannot call is made.

  As a means for solving such a problem, a mobile phone having a function capable of switching the operation mode of the wireless communication unit when watching TV according to the remaining battery level has been proposed. For example, in Japanese Patent Application Laid-Open No. 2005-65129, when the battery level is sufficient when watching TV, the wireless communication unit continues to function even while watching TV while in a standby state, and voice incoming response and mail reception are possible. It was made to become.

However, in the case of such a method of forcibly switching the operation mode according to the remaining battery level, the intention of the user is not reflected. As a technique for solving such a problem, for example, Japanese Patent Laid-Open No. 2006-50555 proposes to control a recording instruction when the remaining battery level becomes a predetermined amount or less according to the initial setting.
JP 2005-65129 A JP 2006-50555 A

  However, in the case of a method in which the operation is defined by the initial setting as in the method of Japanese Patent Application Laid-Open No. 2006-50555, the user continues watching the television or ends the viewing of the television depending on the situation when watching the television. Cannot be determined, and the user experience is not good. In particular, in the case of a mobile phone, since the display area of the screen is narrow, it is important to allow the user to select an operation when the remaining battery level is low without disturbing the user's television viewing.

  An object of the present invention is to provide a mobile phone, a program, and an information storage medium that allow a user to select an operation when the remaining battery level is low without disturbing the user's television viewing.

  In order to solve the above-described problem, the mobile phone according to the present invention is based on information indicating the entire display area of the screen and information indicating the display area of the TV image. An area determination unit that determines whether there is a displayable area, a remaining amount determination unit that determines whether the remaining battery level is equal to or lower than a first predetermined value, and the remaining capacity is equal to or lower than the first predetermined value When there is the displayable area, an image is generated in which a selection image that prompts the user to select whether to continue watching the television is arranged in the displayable area, and there is no displayable area In this case, an image generation unit that generates an image obtained by superimposing the selected image on the television image, and a display unit that displays the image generated by the image generation unit on the screen are included.

  Further, the program according to the present invention allows a computer included in a mobile phone to display the television image in the entire display area based on information indicating the entire display area of the screen of the mobile phone and information indicating the display area of the TV image. An area determination unit that determines whether there is a displayable area other than the display area, a remaining amount determination unit that determines whether the remaining battery level of the mobile phone is equal to or lower than a first predetermined value, and the remaining When the amount is less than or equal to the first predetermined value, and there is the displayable area, an image in which a selection image that prompts the user to select whether or not to continue watching TV is arranged in the displayable area An image generation unit that generates an image in which the selected image is superimposed on the television image when there is no displayable area, and a display that displays the image generated by the image generation unit on the screen Characterized in that to function as control unit.

  An information storage medium according to the present invention is an information storage medium storing a program readable by a computer of a mobile phone, and stores the program.

  According to the present invention, when there is a displayable area, the mobile phone displays the selected image in the displayable area, so that the user's remaining battery level is reduced without disturbing the user's television viewing. The operation can be selected. In addition, even when there is no displayable area, the mobile phone displays the selected image over the TV image, so that it is not necessary to interrupt the viewing of the TV image. The operation when the remaining battery level becomes low can be selected.

  Further, the mobile phone includes a call unit having a call function and a control unit, and the control unit controls the call unit when the selection to continue watching the television is performed. The call function may be disabled.

  According to this, by disabling the call function when the mobile phone is selected to watch TV, the user can watch the TV for a longer time, and the call is not interrupted during viewing. Therefore, you can watch TV comfortably.

  In addition, the mobile phone includes a tuner unit having a TV broadcast receiving function, and the remaining amount determining unit determines whether or not the remaining amount is equal to or less than a second predetermined value at which a minimum necessary call is possible. When the remaining amount becomes equal to or less than the second predetermined value, the control unit disables the reception function by controlling the tuner unit, and controls the call unit to control the call unit. The function may be enabled.

  According to this, even when the remaining battery level is low, the mobile phone can leave the battery amount that can be used for the minimum necessary amount of calls (for example, one call). You can get in touch and request recordings.

  Hereinafter, a case where the present invention is applied to a mobile phone will be described as an example with reference to the drawings. In addition, the Example shown below does not limit the content of the invention described in the claim at all. In addition, all the configurations shown in the following embodiments are not necessarily essential as means for solving the invention described in the claims.

  FIG. 1 is a functional block diagram of a mobile phone 100 in this embodiment. The mobile phone 100 is based on the tuner unit 108 having a TV broadcast reception function, information indicating the entire display area of the screen, and information indicating the display area of the TV image, and includes a display area other than the TV image display area in the entire display area. An area determination unit 110 that determines whether there is a displayable area, a storage unit 120 that stores various data, an image generation unit 130 that generates a selection image, a television image, and the like, and a display unit that displays the television image and the like 140, an audio generation unit 150 that generates television audio and the like, and an audio output unit 160 that outputs television audio and the like.

  The mobile phone 100 includes a battery 180, a remaining amount determination unit 170 that performs determination regarding the remaining amount of the battery 180, a control unit 190 that performs various controls, and a call unit 192 having a call function. ing. Here, the remaining amount indicates the remaining electric energy (Wh) of the battery 180 or the remaining capacity (voltage, V) of the battery.

  The storage unit 120 also includes resolution data 122 indicating the entire display area (for example, resolution) of the screen of the display unit 140, image data 124 for generating a selected image and the like, and reception data 126 received by the tuner unit 108. Etc. are remembered.

  Note that these units may be mounted on the mobile phone 100 using the following hardware, for example. For example, the tuner unit 108 is a so-called one-segment broadcasting reception tuner, the area determination unit 110, the remaining amount determination unit 170, the control unit 190 is a CPU, the storage unit 120 is a RAM, and the image generation unit 130 is an image processor. A circuit such as a liquid crystal panel as the display unit 140, a voice processing circuit as the voice generation unit 150, a speaker as the voice output unit 160, and a general call such as a voice processing circuit, microphone, speaker, etc. as the call unit 192 A unit or the like may be used.

  In addition, the mobile phone 100 may read the program from the information storage medium 200 that stores a program for causing the computer to function as each of these units, and implement the functions of each unit. As such an information storage medium 200, for example, a storage medium using a laser or magnetism such as a CD-ROM, a DVD-ROM, an IC card, a ROM, a RAM, a memory card, and an HDD can be applied. Further, the method of reading the program from the information storage medium 200 may be a contact type or a non-contact type.

  Next, the flow of processing using these units will be described. FIG. 2 is a flowchart showing the flow of processing when the remaining amount of the battery 180 in this embodiment is low. FIG. 3 is a diagram showing the relationship between the remaining amount of the battery 180 and the function used in the present embodiment. FIG. 4 is a diagram illustrating a selection image 300 in an initial state according to the present embodiment.

  First, the user selects, from the selection image 300 displayed on the screen of the mobile phone 100, a television mode for viewing television or a normal mode for performing only a call. For example, as shown in FIG. 3, the operating time of the mobile phone 100 when the user continues to watch TV is about 4 hours, but the operating time of the mobile phone 100 when the user continues to use only the phone. Is about 24 hours. Thus, the power consumption of the mobile phone 100 varies greatly depending on the function used.

  When the television mode is selected, the tuner unit 108 receives the television broadcast and stores it as reception data 126 in the storage unit 120, and the image generation unit 130 generates a television image based on the reception data 126, and displays the display unit. 140 displays the TV image, the sound generation unit 150 generates TV sound based on the reception data 126, and the sound output unit 160 outputs the TV sound. Thereby, the user can view the television using the mobile phone 100.

  Next, the flow of processing when the remaining amount of the battery 180 is reduced will be described based on the flowchart shown in FIG. The remaining amount determination unit 170 determines whether or not the current mode is the television mode, that is, whether or not the television is being watched (step S1). In the television mode, the remaining amount of the battery 180 is the minimum required value (second It is determined whether it is equal to or less than a predetermined value (step S2).

  Here, the necessary minimum value indicates, for example, the remaining amount of the battery 180 that can make one call. The required minimum value varies depending on the model of the mobile phone 100. For example, assuming that one call is 3 minutes and the continuous callable time when the mobile phone 100 is fully charged is about 150 minutes, 1/50 of the remaining charge when the battery 180 is fully charged is the minimum required value. become. However, in actuality, key operations are also performed during a call, and the power consumption fluctuates. Therefore, 1 / 50th to 1 / 10th of the remaining amount when the battery 180 is fully charged may be the minimum required value. .

  When the remaining amount of the battery 180 is less than the necessary minimum value, the control unit 190 controls the tuner unit 108 to stop the reception of the television broadcast, and controls the call unit 192 to enable the call function. Then, the mode is changed to the normal mode (step S3).

  As a result, even when the remaining amount of the battery 180 is low, the user can make a call using the call unit 192.

  On the other hand, when the remaining amount of the battery 180 is greater than the necessary minimum value, the remaining amount determination unit 170 determines whether or not the remaining amount of the battery 180 is equal to or less than a predetermined value (first predetermined value) (step S4).

  Here, as the predetermined value, for example, the remaining amount that allows 30 minutes of television viewing is shown. The predetermined value differs depending on the model of the mobile phone 100. For example, when the continuous TV viewable time when the mobile phone 100 is fully charged is about 4 hours, 1/8 of the remaining amount of the battery 180 when fully charged becomes the required minimum value. However, in actuality, a channel change operation or the like is also performed when watching TV, and the power consumption fluctuates. Therefore, 1/10 to 1/5 of the remaining amount when the battery 180 is fully charged is a predetermined value. Also good.

  When the remaining amount of the battery 180 is equal to or less than the predetermined value, the area determination unit 110 has displayable areas other than the TV image display area in all display areas based on the resolution data 122 and information indicating the TV image display area. Is determined (step S5). In the present embodiment, it is assumed that the display area of the TV image is 180 × 320 pixels equivalent to one-segment broadcasting and is fixed. For example, when the entire display area of the screen of the display unit 140 is 240 × 320 pixels, there is a displayable area for 60 × 320 pixels in total.

  If there is a displayable area, the image generation unit 130 generates an image in which the selected image is arranged in the displayable area based on the image data 124 (step S6). FIG. 5 is a diagram showing an image 302 including a selected image when the remaining amount of the battery 180 in this embodiment is low and there is a displayable area.

  For example, in FIG. 5, a selection image showing a character string “Battery is low. Please select a mode.” Is displayed in the displayable area of 30 × 320 pixels at the top of the screen, and the bottom 30 of the screen. A selection image showing options of “television mode” and “normal mode” is displayed in a displayable area of × 320 pixels.

  Based on the user operation information, the control unit 190 determines whether the normal mode is selected and a television viewing end instruction is issued (step S7). If the television viewing end instruction is issued, the control unit 190 controls the tuner unit 108. Then, the reception of the television broadcast is stopped, and the call unit 192 is controlled to enable the call function, thereby changing to the normal mode (step S3).

  On the other hand, when there is no displayable area, the image generation unit 130 generates an image in which the selected image is superimposed on the television image based on the image data 124 (step S8). FIG. 6 is a diagram illustrating an image 304 including a selected image when the remaining amount of the battery 180 in the present embodiment is low and there is no displayable area.

  For example, when the entire display area of the screen of the display unit 140 is 180 × 320 pixels, the television image is displayed using the entire area of the screen. In such a case, the selected image indicating the above-described character string or option is displayed superimposed on the television image. In the example shown in FIG. 6, the character string and the background of the options are in a non-transparent state, but may be displayed in a semi-transparent state.

  The mobile phone 100 determines whether or not it is in an end state (for example, a state where the power of the mobile phone 100 is turned off, a state where the voltage of the battery 180 is equal to or lower than the usable voltage, etc.) (Step S9). When not in the state, the above processing (steps S1 to S8) is continued, and when the end state is reached, the processing ends.

  As described above, according to the present embodiment, when there is a displayable area, the mobile phone 100 displays the selected image in the displayable area, thereby preventing the user from remaining the battery without disturbing the user's television viewing. The operation when the amount is reduced can be selected. In addition, even when there is no displayable area, the mobile phone 100 displays the selected image on the television image so that viewing of the television image is not interrupted. The user can select an operation when the remaining battery level is low.

  In addition, according to the present embodiment, when the remaining amount of the battery 180 falls below the required minimum value, the mobile phone 100 disables the TV broadcast reception function and enables the call function to Even when the remaining amount of 180 is reduced, it is possible to leave a remaining amount that allows a minimum necessary call, so that it is possible to receive an emergency contact or to request a recording.

  Further, according to the present embodiment, the mobile phone 100 can execute a function (television viewing function or call function) reflecting the user's intention at the time when the remaining amount of the battery 180 is low.

  In addition, application of this invention is not limited to the Example mentioned above, A various deformation | transformation is possible. For example, the control unit 190 may disable the call function by controlling the call unit 192 when a selection to start watching TV or a selection to continue watching TV is performed.

  According to this, the mobile phone 100 disables the call function when the TV viewing is selected, so that the user can watch the TV for a longer time and the call is interrupted during the viewing. So you can watch TV comfortably.

  When the display area of the television image is variable, the area determination unit 110 may determine the display area of the television image based on the reception data 126.

  In the above-described embodiment, the control unit 190 controls only the TV viewing function and the call function. However, for example, various functions of the mobile phone such as an e-mail transmission / reception function and a WEB browsing function are provided. It may be controlled according to
