  Further, after the display according to the above-described various contents displayed superimposed on the television screen is started in response to the operation of the enter key 38, the input / output control unit 14 determines a predetermined value based on the timing data of the timer unit 19. You may make it delete automatically, if time passes. Further, when one common icon and a plurality of individual icons derived from the common icon are displayed on the television screen in a superimposed manner (see FIG. 6A), a predetermined time from the start of display of these icons. A display method may be used in which a plurality of individual icons are erased after the passage of time, only the common icons are displayed, and then the common icons disappear completely after a predetermined time.

  Further, the content displayed in a superimposed manner may be displayed in a superimposed manner on a television screen on which a video by television broadcasting and character information such as BML are simultaneously displayed (see FIG. 6B).

  FIG. 6B shows a state in which the main menu is displayed superimposed on the BML character information. In this manner, the content displayed in a superimposed manner may be displayed in a superimposed manner on the character information on a television screen on which video by television broadcasting and character information such as BML are simultaneously displayed.

  Alternatively, when it is not necessary to display the TV screen on the display unit 15 at the same time, such as when an application function of an AV (Audio Visual) function is activated to use the camera function or the music player function to shift to the application mode, The input / output control unit 14 may erase the television screen, which is a standby screen, and display information for using the AV function, for example, an image being shot by the camera 23. When the camera 23 finishes shooting (when the application mode ends), it shifts to the standby mode and the original television screen is displayed. Specifically, when a television screen is displayed on the display unit 15, the input / output control unit 14 inputs output data from the video control unit 13 and displays an image based on the data on the display unit 15. When the shooting key 40 of the key operation unit 21 is operated while the TV screen is displayed, the CPU 17 detects that the shooting key 40 has been operated based on the operation signal from the key operation unit 21 and enters it accordingly. The output controller 14 is instructed to input captured image data output from the camera 23. When this instruction is input, the input / output control unit 14 switches the input data from the output data from the video control unit 13 to the output data from the camera 23 based on this instruction. Thereafter, an image (subject image) based on image data input from the camera 23 is displayed on the display unit 15. As a result, the screen of the display unit 15 is switched from the television screen to the display screen of the subject image being shot.

  The user may switch the standby screen to a television screen or a conventional standby screen such as wallpaper display by operating the key operation unit 12.

The key operation may be changed depending on the setting state of the standby screen.
If the user sets the standby screen to a conventional standby screen such as a wallpaper display, the standby in the present invention described above is changed to a key operation like a conventional mobile phone instead of a key operation at the time of a television screen. Also good.

(Other standby screen display examples)
The standby screen described above is a television screen, but may be a radio screen. 7A and 7B show a radio screen for the standby screen in the present embodiment. Here, the radio screen refers to a screen that displays an image based on the radio broadcast program additional information 111.

  FIG. 7A shows a state where a radio screen is displayed on the display unit 15 as a standby screen. When the user operates the enter key 38 of the key operation unit 21 while the radio screen of FIG. 7A is displayed, the main menu image of the mobile phone 100 is displayed superimposed on the radio screen as in FIG. 5B. (See FIG. 7B).

(Processing procedure according to the open / close state)
FIGS. 8A and 8B show a processing flowchart according to the first embodiment. When the clamshell mobile phone 100 is closed, the processing operation of FIG. 8A is repeated. When the closed state is switched to the opened state, the process in FIG. 8A is forcibly terminated and the process in FIG. 8B is started.

  The processing flow of FIG. 8A shows that a TS broadcast is received by the digital broadcast receiver 4 during a period when it is detected that the cellular phone 100 is in a closed state when the mobile phone 100 is turned on. 5 (step S3). Here, during the closed period, the input / output control unit 14 does not input the data from the audio decoder 7 and the video decoder 6 to the audio control unit 12 and the video control unit 13 under the control of the CPU 17. (Step S5). Accordingly, since no data is output from the audio control unit 12 and the video control unit 13, neither an image nor audio based on the TV broadcast signal is output to the display unit 15 and the speaker 20.

  Thus, in the closed state, although the TV broadcast signal is being received, the TV screen and sound are not output.

  In the closed state, the CPU 17 performs predetermined processing to be performed in the closed state, processing for incoming mails and calls, and the like. Therefore, even when the clamshell mobile phone 100 is in a closed state, it receives the TV broadcast wave and detects the presence or absence of an incoming e-mail or call or the presence of a transmission request via the antenna 1 and the data transmission / reception unit 16. It is in the state to do. Here, in order to simplify the description, details of these functions are omitted.

  When the CPU 17 detects that the mobile phone 100 is switched to the open state based on the detection result of the open / close sensor 67, the processing of FIG.

  First, under the control of the CPU 17, the input / output control unit 14 controls the audio control unit 12 and the video control unit 13 so as to input data from the audio decoder 7 and the video decoder 6 (step S5). Therefore, since the audio control unit 12 and the video control unit 13 output image data and audio data of the program based on the TV broadcast signal, the TV screen and TV broadcast audio are output to the display unit 15 and the speaker 20. (Step S7).

  In a state where the television screen is displayed as the standby screen, the CPU 17 determines whether or not any key is operated by the user based on an operation signal input from the key operation unit 21 and whether the operated key is the power key 36. Is detected (steps S9 and S11). While it is detected that the key is not operated or the key is operated but the power key 36 is operated (NO in step S9, YES in step S11), the process returns to step S7, and the processes in steps S77 to S9 are repeated. It is.

  On the other hand, when the CPU 17 detects that the input key type is not the power key 36 and that another key is operated (NO in step S11), the CPU 17 causes the display unit 15 to wait for the input / output control unit 14. Control is performed so that the main menu image of the mobile phone 100 is displayed on the screen (TV screen) (step S13).

  Thereafter, the CPU 17 detects whether or not any key operation has been performed based on an operation signal input from the key operation unit 12 (step S15). While it is detected that no key operation is performed, the CPU 17 is in a so-called standby state, and the display of the television screen as the standby screen in step S13 is continued.

  On the other hand, if it is detected that any key operation has been performed (YES in step S15), the CPU 17 detects whether or not the operation key is the power key 36 (step S17). If it is detected that power key 36 has been operated (YES in step S17), the process proceeds to step S20.

  In step S <b> 20, the CPU 17 controls the input / output control unit 14 to erase the main menu image displayed on the television screen of the display unit 15. Thereafter, the process returns to step S7.

  On the other hand, if it is detected that the operated key is a key other than the power key 36 (NO in step S17), the CPU 17 starts the application process in accordance with the operation signal of the operated key. Are read from the storage unit 18 via the input / output control unit 14 and the read program is executed (step S19). Thereby, in the mobile phone 100, application processing designated by the user is started.

  For example, the user can selectively specify a desired function by key operation from the main menu image superimposed on the television screen, and thus the function specified by key operation is executed.

  Although the standby screen is a television screen here, it may be the radio screen described above. The operation in that case is as follows.

  First, in the state where the cellular phone 100 is closed, not the TV broadcast signal is received, but the radio broadcast signal is received via the antenna 3 and the digital radio receiver 8. The received radio broadcast signal is output to the audio data decoder unit 9 and the program additional information decoder unit 11 (step S3). Here, in the closed period, the input / output control unit 14 inputs the data from the equalizer 10 and the program additional information decoder unit 11 to the audio control unit 12 and the video control unit 13 under the control of the CPU 17. Control is performed so as not to occur (step S5). Accordingly, since no data is output from the audio control unit 12 and the video control unit 13, neither an image nor radio audio based on the program additional information 111 according to the radio broadcast signal is output to the display unit 15 and the speaker 20.

  Thus, in the closed state, although the radio broadcast signal is being received (tuned and decoded), the radio screen and radio sound are not output.

  When the CPU 17 detects that the mobile phone 100 is switched to the open state based on the detection result of the open / close sensor 67, the input / output control unit 14 controls the audio control unit 12 and the video control under the control of the CPU 17. The unit 13 is controlled to input data from the equalizer 10 and the program additional information decoder unit 11 (step S7). Therefore, since the audio control unit 12 and the video control unit 13 output the program additional information 111 and the radio audio data of the radio broadcast signal, the radio screen and radio audio are output to the display unit 15 and the speaker 20 (steps). S7).

  Subsequent processing is the same as that when a TV screen is displayed as a standby screen, and thus description thereof is omitted.

(Display processing related to the standby screen using the timer function)
Next, a procedure for deleting the main menu image superimposed on the standby screen from the standby screen as time passes will be described with reference to the flowchart of FIG.

  The process of FIG. 9 is obtained by changing a part of the process of FIG. In FIG. 9, the processes in steps S7 to S20 are performed in the same manner as in FIG. In step S13, the main menu image is displayed so as to overlap the standby screen. However, after the display, the main menu image is erased when a predetermined time elapses. Therefore, the following point is changed from the process of FIG.

  When the CPU 17 displays the main menu image in step S13a, the timer unit 19 starts measuring time. The CPU 17 detects whether any key operation has been performed (step S15). If no key operation is detected (NO in step S15), the CPU 17 reads data indicating a predetermined time stored in the storage unit 18 in advance, and compares the read predetermined time data with the timing data input from the timer unit 19. If it is detected that the measured time data is greater than the predetermined time data based on the comparison result (YES in step S15a), in step S20, the main menu image displayed superimposed on the standby screen (television screen or radio screen) is input / output. It is erased by the control unit 14. As a result, only the standby screen is displayed on the display unit 15.

  On the other hand, if it is detected based on the comparison result that the time measurement data ≦ predetermined time data (NO in step S15a), the process returns to step S15, and the state in which the main menu image is displayed superimposed on the standby screen continues.

  If it is detected that any key operation is performed within a predetermined time after the display of the main menu image is started (YES in step S15), the processing after step S17 is performed in the same manner as described above.

  In this way, when no key operation is performed within a predetermined time after the main menu image is superimposed on the standby screen, the image superimposed on the television screen or radio screen that is the standby screen is deleted and the television screen is displayed. The viewing image (video) on the screen or radio screen is easy to check.

(About suspend processing)
When the clamshell mobile phone 100 according to the present embodiment is closed, the display unit 15 is located inside the housing and hidden from the outside, so that the user cannot see the image. Therefore, it is not necessary to display a standby screen (television screen or radio screen) in the closed state. Therefore, in the present embodiment, in the closed state after the power is turned on until the power is turned off, the mobile phone 100 shifts to an operation mode for suppressing power consumption (referred to as a suspend mode). .

  The suspend mode according to the present embodiment will be described with reference to the flowchart of FIG. Here, it is assumed that the mobile phone 100 is in an open state in which the power is turned on in advance, and the display unit 15 displays a television screen as a standby screen and a main menu image superimposed thereon. Thereafter, when the open state is changed by the user to the closed state, the CPU 17 detects the transition from the open state to the closed state based on the detection signal of the open / close sensor 67. In response to detecting this state transition, the CPU 17 starts processing according to the flowchart of FIG.

  First, the CPU 17 outputs an instruction to the input / output control unit 14 to shift to the suspend mode (step S41). In response to the input of the instruction, the input / output control unit 14 erases the main menu image displayed on the display unit 15 and then erases the standby screen displayed (step S43). Thereafter, the mobile phone 100 is set to the suspended state.

  Specifically, the input / output control unit 14 turns off (cuts off) the power supplied from the power supply circuit 68 to the display unit 15 (step S47). Thereby, the suspend mode according to the present embodiment is realized.

  In this way, in the suspend mode, the power supplied to the display unit 15 is cut off, so that the power consumption in the mobile phone 100 can be reduced accordingly.

  In the suspend mode, a circuit for receiving an audio signal from TV broadcasting and radio broadcasting and outputting it from the speaker 20 is supplied with power, and the mobile phone 100 is carried in a closed state. The user may be able to listen to the sound of the TV broadcast or the radio broadcast from the speaker 20 even when the user is on the table.

  After shifting to the suspend mode, the CPU 17 detects whether or not an instruction to cancel the suspend mode is given by a key operation via the key operation unit 21 (step S49). During the period when the release instruction is not given (NO in step S49), the suspend mode is continued.

  The instruction to cancel the suspend mode corresponds to a detection signal indicating that the user has switched to the open state by operating the mobile phone 100. That is, the CPU 17 detects the end of the suspend mode in response to detecting the transition from the closed state to the open state in the suspend mode (YES in step S49).

  When the CPU 17 detects the end of the suspend mode, the CPU 17 gives an instruction signal for ending the suspend mode to the input / output control unit 14, so that the input / output control unit 14 displays that the power supply has been cut off in response to the input of the instruction signal. The power supply to the unit 15 is resumed (step S51). Thereby, the input / output control unit 14 inputs the video data given from the video control unit 13, and displays a television screen based on the input video data on the display unit 15 as a standby screen (step S53).

It is assumed that the contents of the storage unit 18 are not lost during suspension.
(Embodiment 2)
In the present embodiment, the standby screen of the display unit 15 is switched according to the broadcast signal reception status.

  The mobile phone 100 cannot always receive broadcast signals normally. For example, when the reception situation deteriorates due to the movement of the user who carries the mobile phone 100, or even if it can be received, some noise is mixed in the received signal, noise appears on the screen, or the video is interrupted. There are cases where it is impossible to replay. Also, immediately after the start of digital TV broadcast signal reception or during channel selection (decoding), no broadcast signal can be received, so a black screen is displayed on the display unit 15 without displaying any image. There is a case where it is left waiting for a while.

  In a state where a TV broadcast signal can be normally received, for example, as shown in FIG. 11A, a standby screen for a program by television broadcast is displayed on the display unit 15. In the lower part of the screen, information 151 for identifying the TV broadcast station being received, information 152 for identifying the channel being received, and information 153 indicating the title of the program being received are displayed. Information 151-153 is displayed as follows. That is, EPG (Electronic Program Guide) information transmitted by being superimposed on the received TV broadcast signal is extracted by the video decoder 6 and output to the input / output control unit 14. The input / output control unit 14 is an image according to the provided EPG information. Is displayed on the display unit 15 so that the information 151 to 153 is displayed on the TV screen which is a standby screen.

  After that, when the user carries the mobile phone 100 and moves to a place where the digital television broadcast signal cannot be received at all, or can be received but cannot receive a signal (amount of information) sufficient for decoding, the TS decoder 5 or the video decoder 6 does not output a signal in response to the fact that the decoding process is impossible, so the input / output control unit 14 cannot update and display the standby screen on the display unit 15. In this case, the image of the program disappears on the screen of the display unit 15, and the input / output control unit 14 displays a predetermined image informing that tuning is being performed instead of the television screen. In the conventional mobile phone, a black image including the message 154 being tuned is displayed at this time as shown in FIG. 11B. In this embodiment, the user including the message 154 being tuned is enjoyed. An image is displayed.

  For example, the notification screen during tuning may be an image shown in FIG. The notification screen during tuning (FIG. 12B) that is switched from the TV screen in FIG. 12A reads out image data (image data of a photograph taken) read out from the storage unit 18 by the input / output control unit 14. An image based on the read image data. At this time, the input / output control unit 14 also displays a message 154 (“PLEASE WAIT...”) Indicating that tuning is being performed on the display unit 15.

  Thus, when it takes time to decode (tune) a broadcast signal, such as when the reception status of radio waves is poor, the screen of the display unit 15 automatically displays an image other than the TV screen or radio screen during the tuning notification screen. The image for the notification screen during tuning may be as follows.

  Another example of the switched image may be a radio screen or a television screen. In other words, if a radio broadcast signal can be received while the television screen is displayed as the standby screen, it is received and the radio screen based on the program additional information 111 is displayed as a notification screen during tuning. Good. Conversely, if a TV broadcast signal can be received while a radio screen is displayed as a standby screen, it may be received and the television screen displayed as a notification screen during tuning.

  Also, it may be a wallpaper, and the data of this wallpaper is stored in the storage unit 18 in advance, so that the input / output control unit 14 may read and display it or via the external I / F 24. It may be acquired from an external memory such as a memory card and displayed.

  Alternatively, video data recorded in advance in the television recording mode may be read from the storage unit 18 and reproduced and displayed on the display unit 15. The content data 44 in the server may be read and an image based on this may be displayed. Alternatively, the program information acquired from the EPG information may be stored in the storage unit 18 in advance and read and displayed. Or you may display the icon regarding the program acquired from BML. Alternatively, a channel list may be displayed. Furthermore, an image for selecting another function of the mobile phone 100 may be displayed.

  In the case of a television screen, a still image that has been displayed until immediately before by a TV broadcast signal may be displayed as a notification screen during tuning. Similarly, in the case of a radio screen, a radio screen of a still image that has been displayed until immediately before by a radio broadcast signal may be displayed as a notification screen during tuning. It should be noted that such a still image is displayed for a short period of time, which is the predetermined period counted by the timer unit 19, and when it is still not received, the screen may be switched to the above-described screen that displays the message 154. Good.

  Here, when the input / output control unit 14 detects a state in which the TV broadcast signal cannot be received (the decoded signal is not output from the video control unit 13) while receiving the TV broadcast signal, the input / output control unit 14 outputs the TV broadcast signal. The duration of a state where reception is not possible is counted based on the timing data. Then, when it is detected that the detected duration exceeds the predetermined time indicated by the data read from the storage unit 18, the display unit 15 can display an image based on other data from the standby screen, which is a television screen, as described above. It may be switched. The predetermined period may be stored in the storage unit 18 as fixed value data, or the user operates the key operation unit 21 to variably set the predetermined period data, and the set predetermined time data is stored in the storage unit 18. May be stored.

  FIGS. 13A and 13B are diagrams showing a display screen switching process procedure in accordance with the broadcast signal reception status. In FIG. 13A, the processing (steps S3 and S5) in the state where the clamshell is closed is performed in the same manner as described above.

  When the CPU 17 detects that the clamshell has been opened, the process of FIG. 13B is started. First, when the input / output control unit 14 receives a detection signal indicating that it has been opened by a notification from the CPU 17, the input / output control unit 14 detects whether decoding is possible using the function of the decoding enable / disable determining unit 34 (step S54a). If it is determined that decoding is possible (YES in step S54a), the process proceeds to step S61 described later.

  If the decoding possibility determination unit 34 does not determine that decoding is possible (NO in step S54a), the input / output control unit 14 starts measuring a predetermined time based on the timing data input from the timer unit 19 (step S54a). S54b). Thereafter, the time measurement data is compared with data for a predetermined time read from the storage unit 18, and based on the comparison result, it is detected whether the predetermined time has elapsed since the start of time measurement (step S55). When it is detected that the predetermined time has passed (YES in step S55), the input / output control unit 14 reads predetermined data from the storage unit 18, and displays a notification screen during tuning based on the read predetermined data on the display unit 15 ( In step S57), the process proceeds to step S59.

  If it is detected that the predetermined time has not elapsed (NO in step S55), the decoding possibility determination unit 34 detects whether decoding is possible again (step S59). If it is not determined that decoding is possible (NO in step S59), the process returns to step S55, and the subsequent processes are similarly repeated. On the other hand, if the decoding possibility determination unit 34 detects that decoding is possible (YES in step S59), the process proceeds to step S61.

  In step S61, the input / output control unit 14 displays a television screen based on the TV broadcast signal input from the video control unit 13 on the display unit 15 as a standby screen.

  Therefore, if it is not determined that decoding is possible even after a predetermined time has elapsed since the screen is opened, the display unit 15 does not display a screen based on predetermined data for informing that tuning is being performed instead of a television screen. Can be displayed.

(Embodiment 3)
The form of the mobile phone 100 described above is not limited to the clamshell type. For example, a slide type in which the key operation unit 21 appears on the table by sliding two housings integrally connected so as to be slidable with each other may be used.

  In the clamshell type, the TV screen is displayed when the screen is opened. However, in the slide type, as shown in FIG. 14, after the power is turned on and started, the TV screen or The radio screen is displayed. When the TV screen by the TV broadcast being received is displayed, when the user operates a predetermined key (for example, enter key 38) of the key operation unit 21 to activate another application function, the main menu image is changed to the TV image. It is displayed superimposed. At this time, the main menu image may be displayed superimposed on the television screen when a predetermined key is operated, or may be displayed superimposed on the television screen by sliding the two housings together. Even in the case of the slide-type mobile phone 100, other functions are the same as those of the clamshell-type mobile phone 100 described above. The present invention can also be applied to the cycloid mobile phone 100.

(Display screen transition)
FIG. 15 shows a state transition between the screen switching in the display unit 15 according to each embodiment of the present invention and the key operation for switching the screen. First, when a standby screen (television screen or radio screen) 60 is displayed, if any key operation is performed, a menu image 61 is displayed superimposed on the standby screen. In this state, when any key operation (excluding the power key operation) is further performed, the standby screen (menu image) is deleted and the screen is switched to the display of the screen 62 for the application corresponding to the operated key. When the clear key 41 of the key operation unit 21 is operated while the screen 62 is being displayed, the menu image is switched to the display of the menu screen 61 displayed on the television screen, and when the clear key 41 is further operated, the menu is displayed. The screen 61 is switched to the standby screen 60 and displayed.

  Further, when the power key 36 is operated while the application screen is displayed on the display unit 15, the display is switched to the display of the standby screen 60. When the power key 36 is operated while the menu screen 61 is displayed, the menu screen 61 is deleted and a standby screen is displayed.

  As described above, the standby screen 60 refers to a screen that transitions when the user operates the power key 36 while any screen is displayed.
