(Example 1)
A first embodiment of the present invention will be described below with reference to FIGS.
This embodiment exemplifies a case where the present invention is applied to a mobile phone device as a mobile terminal device. FIG. 1 shows that a mobile phone device 1 with a digital TV broadcast receiving function is placed (connected) on a cradle (charging base) 2. It is the figure which showed the state which carried out.
In the state in which the cellular phone device 1 is placed on the cradle 2, for example, a television broadcast signal received by the television broadcast reception function of the cellular phone device 1 is transmitted via the cradle 2 to a PC (personal computer) 3 or a fixed television. By transferring the data to the device 4 by infrared communication, the TV broadcast program viewed on the mobile phone device 1 can be continuously viewed on the PC 3 or the fixed television device 4. In addition to viewing TV broadcasts, for example, movie content externally supplied from a recording medium or downloaded and received from the Internet can be transferred to the PC 3 or the fixed TV device 4 via the cradle 2 for viewing. .

The cradle 2 has a charging function for supplying a charging current to a secondary battery (not shown) of the mobile phone device 1 when the mobile phone device 1 is placed while being connected to an AC power source. Video transfer function for transferring the video signal to the PC 3 / fixed TV device 4 by relaying the data of the video signal from the mobile phone device 1 with the external monitor (PC 3 / fixed TV device 4) via infrared communication Intelligent cradle equipped with
Further, the PC 3 or the fixed television apparatus 4 as an external monitor receives a video signal transferred from the mobile phone device 1 via the cradle 2 and outputs the video data. When the PC 3 or the fixed television apparatus 4 receives a portable-size video signal transmitted from the cradle 2 by infrared communication, the video signal is changed to its current screen size and displayed and output. .

FIG. 2 is a block diagram showing basic components of the cellular phone device 1 with a digital television broadcast receiving function.
The CPU 11 is a central central processing unit that controls the overall operation of the mobile phone device according to various programs in the storage unit 12. The storage unit 12 is an internal memory, and has a program area and a data area. In this program area, a program for realizing the present embodiment according to an operation procedure shown in FIGS. Stored. The recording medium 13 is a detachable portable memory that supplies various data programs externally. For example, the recording medium 13 is composed of smart media, an IC card, and the like, and supplies contents such as videos and music to the outside. The recording medium 13 is also used. The memory 14 is an internal memory having a work area, and various data in the memory 14 is saved in the storage unit 12 as necessary.

  The telephone communication unit 15 takes in a signal from the reception side of a transmission / reception unit (baseband unit) connected to an antenna that constitutes a radio unit, demodulates it into a reception baseband signal, and then receives a reception speaker via the acoustic control unit 16. The sound is output from 17. Further, the telephone communication unit 15 takes in the voice data input from the transmission microphone 18 from the acoustic control unit 16, encodes it into a transmission baseband signal, and then gives it to the transmission side of the transmission / reception unit to output from the antenna. . On the other hand, the content received and acquired via the telephone communication unit 15 by the Internet connection function or the like is given to the main display unit 20 such as an LCD (Liquid Crystal Display) via the display control unit 19 for display output. The sub display unit 21 displays the current date and time, a simple message, an icon, and the like.

  The TV broadcast receiving unit 22 receives terrestrial digital TV broadcasts for mobile receivers such as mobile phones, and can receive electronic program guides (EPG) in addition to TV video and audio information. The TV broadcast receiving unit 22 is connected to the TV antenna and receives a broadcast unit (analog circuit unit) that extracts a broadcast signal. The received broadcast signal is demodulated by OFDM (orthogonal frequency division multiplexing) or multiplexed. It has a digital circuit section that separates video, audio, and data (character data) from a signal, decodes them, and decompresses compressed data. Television video data and character data are displayed and output from the main display unit 20, and television audio data is output from the sound speaker 23. In addition to the TV video from the TV broadcast receiving unit 22, video output processing for outputting video content externally supplied from the recording medium 13 or video content downloaded and received via the Internet is generically referred to below. This is called video application processing.

  The key operation unit 24 performs dial input, character input, command input, and the like, and the CPU 11 executes processing according to a key input signal from the key operation unit 24. The cradle connection unit 25 charges a secondary battery (not shown) with a charging current from the cradle 2 when connected to the cradle 2, and the CPU 11 detects a connection detection signal output from the cradle connection unit 25. Based on the above, it is detected whether the apparatus main body is connected to the cradle 2 or not. Here, when the apparatus main body is connected to the cradle 2 and the video application process is being performed, the CPU 11 outputs video data to the cradle connection unit 25 under certain conditions. To cradle 2.

The style detection sensor 26 can detect each style changing according to the arrangement state of two casings (display unit casing and operation unit casing) constituting the apparatus main body. For example, a magnetic sensor or a micro switch The CPU 11 discriminates each style of the apparatus main body based on each detection signal from the style detection sensor 26.
3A shows a state in which the display unit casing 27 including the display unit 20 and the operation unit casing 28 including the key operation unit 24 are opened in the state in which the apparatus main body is connected to the cradle 2 (opened). In this “open style”, the display unit 20 is in a vertically long display state.

FIG. 3B shows a style in which the display unit casing 27 is rotated from the “open style” state to the operation unit casing 28 to change from the portrait display state to the landscape display state, that is, video display. "View style" in a state suitable for In this way, the apparatus main body has a configuration that can be appropriately changed between a vertically long display state (open style) and a horizontally long display state (view style) by rotating the display unit housing 27 with respect to the operation unit housing 28. ing.
Here, in the state in which the apparatus main body is connected to the cradle 2, if the display unit 20 is “open style” in a vertically long display state, an image is output from the display unit 20. If it is “view style”, the video signal to be output is transferred from the cradle connection unit 25 to the cradle 2.

  In this case, the CPU 11 gives a video output command to the external monitor via the cradle 2 when starting the video application process, and starts an operation of transmitting a video signal such as a television broadcast or video content. At the end of the video application process, an output end command is given to the external monitor via the cradle 2. Note that the PC 3 or the fixed television apparatus 4 changes the portable-size video signal to its current screen size, adjusts the image quality, corrects it to a high-quality image, and displays it.

  Next, the operation concept of the mobile phone device in the first embodiment will be described with reference to the flowcharts shown in FIGS. Here, each function described in these flowcharts is stored in the form of a readable program code, and operations according to the program code are sequentially executed. In addition, the operation according to the above-described program code transmitted via the transmission medium can be sequentially executed. This is the same in other embodiments described later. In addition to the recording medium, the program / data supplied from the outside via the transmission medium can be used to execute operations specific to this embodiment.

4 and 5 are flowcharts showing the overall operation of the mobile phone device that starts executing when the power is turned on.
First, the CPU 11 operates the telephone communication unit 15 to register the current position, and enters a standby state for telephone / mail while reading and displaying a predetermined standby image (step A1). In this state, when it is detected that there is an incoming call / mail (YES in step A2), an incoming call notification for generating and outputting an incoming melody is performed and a call or mail incoming process is executed (step A3).

  If any key operation is performed in the standby state (YES in step A4), it is checked whether the above-described key operation for starting the video application is performed (step A5). NO), as a process corresponding to the operation, for example, a telephone call process, a mail creation process, a mail transmission process, etc. are executed (step A6), and then the standby state is returned (step A1), but the video application is activated. When instructed by a user operation (YES in step A5), the application is activated (step A6).

  Based on the detection signal from the cradle connection unit 25, it is checked whether the apparatus main body is placed on the cradle 2 (whether the cradle is connected) (step A7). Now, when the activation of the video application is instructed without being connected to the cradle 2 (NO in step A7), for example, when a TV-on operation is performed in order to watch the TV on the go, FIG. 5, the current style is determined based on the detection signal from the style detection sensor 26, and if it is a horizontally long display style (view style) suitable for video display, the display unit (portable screen) 20 Although the video is displayed and output (step A14), if it is “open style” (NO in step A10), it is checked whether it is connected to the cradle 2 (step A11). Since it is in a non-connected state that is not connected to the cradle 2, a vertically long image is displayed and output from the mobile screen 20 (step A13).

  In this state, it is checked whether or not any key operation has been performed (step A15), whether the detection signal from the cradle connection unit 25 has changed, that is, whether it is connected to the cradle 2 or disconnected from the cradle 2. (Step A18), it is checked whether the detection signal from the style detection sensor 26 has changed, that is, whether the style of the apparatus main body has been changed (step A19). If any key operation is performed (YES in step A15), if it is an end operation for instructing the end of the video application (YES in step A16), the process is terminated and the above standby state is entered. Returning (step A1 in FIG. 4), if it is another operation (NO in step A16), processing corresponding to that operation, such as audio adjustment, channel switching, fast-forward playback, etc. is performed (step A17).

  Also, whether the detection signal of the cradle connection unit 25 has changed during the video output on the portable screen 20, that is, whether the apparatus main body is placed (connected) on the cradle 2, or the apparatus main body is removed from the cradle 2 and connected Is checked (step A18), and if a change in the cradle connection is detected, the process returns to step A10. If it is connected to the cradle 2 during video output on the mobile screen 20 (YES in step A18), if it is in the “view style” state (YES in step A10), the video output on the mobile screen 20 remains unchanged. However, when the cradle is connected in the “open style” state (NO in step A11), a video output command is given to the external monitor via the cradle 2 and the video signal transmission operation is started. (Step A12). As described above, when the mobile terminal 20 is connected to the cradle 2 in the “open style” state during video output on the mobile screen 20, the mobile screen 20 is switched to video output to an external monitor.

  Also, when the apparatus main body is removed from the cradle 2 and the cradle connection is released (YES in step A18), the process proceeds to step A10 described above. At that time, when the connection is canceled by “view style”, the video output on the mobile screen 20 remains after the cancellation, but when the “open style” connection is canceled (NO in step A11), the mobile screen is displayed from the external monitor. The video output is switched to 20 (step A13). In this case, a vertically long image is displayed on the mobile screen 20.

  On the other hand, if the detection signal from the style detection sensor 26 has changed (YES in step A19), if it is a change from “open style” to “view style” (YES in step A10), it is connected to the cradle 2. Regardless of whether or not the image is displayed, a horizontally long image is displayed and output from the portable screen 20 (step A14). Conversely, when the “view style” is changed to “open style” (NO in step A10), if not connected to the cradle 2 (NO in step A11), a vertically long image is displayed and output from the mobile screen 20 (step A11). Step A13). Further, when the “view style” is changed to “open style” and the cradle 2 is connected (YES in step A11), the mobile screen 20 is switched to video output to an external monitor (step A12).

  On the other hand, if the activation of the video application is instructed while the cradle is connected (YES in step A7 in FIG. 4), the process proceeds to step A8, a video output command is given to the external monitor via the cradle 2, and the video signal is transmitted. Start operation and output video from an external monitor. In this state, the flow proceeds to the flow of FIG. 5 to check the presence / absence of key operation (step A15), the presence / absence of cradle connection change (step A18), and the presence / absence of style change (step A19). . That is, when the video application is activated while the cradle is connected, the video output from the external monitor is performed regardless of the current style. After the activation, the same operation as described above is performed.

  As described above, in the first embodiment, the CPU 11 determines whether or not the external monitor (PC 3 / fixed television device 4) is connected via the cradle 2, and from the display unit (portable screen) 20 on the device main body side. By determining whether or not video output is in progress, determining whether to instruct video output from the portable screen 20 or instructing video output from an external monitor according to each determination result, and performing output control thereof It is possible to easily realize switching between video output on the portable screen 20 and video output on an external monitor without performing any special operation.

  In this case, if connected to the cradle 2 and outputting video, the CPU 11 can switch to video output on an external monitor instead of video output from the mobile screen 20. That is, when connected to the cradle 2 during video output from the mobile screen 20, the CPU 11 can switch to video output on an external monitor instead of video output from the mobile screen 20. When the video application process is activated by a user operation while connected to the cradle 2, it is possible to instruct video output on an external monitor. Further, when the apparatus main body is pulled out from the cradle 2 and the connection with the cradle 2 is released while the video is being output from the external monitor while being connected to the cradle 2, the video output on the portable screen 20 is instructed. be able to.

  In addition, the CPU 11 determines whether or not the external monitor (PC 3 / fixed television device 4) is connected via the cradle 2, determines the current style of the device body, and determines whether the current state of the device body is from the portable screen 20 according to each determination result. By determining whether to instruct video output or video output from an external monitor and performing output control thereof, video output is performed on the mobile screen 20 without any special operation, or video is output on an external monitor. Switching between output and output can be easily realized.

  In this case, if the current style is “view style” when the video application process is activated by a user operation without being connected to the cradle 2, a horizontally long video is displayed and output from the mobile screen 20. In the case of “open style”, a vertically long image is displayed and output from the mobile screen 20. In this way, when the video image is output from the mobile screen 20, if the style at the time of connection remains “view style” when connected to the cradle 2, the horizontally long video on the mobile screen 20 is continuously displayed. If the style when the cradle is connected is “open style”, the video is displayed and output from the external monitor.

On the other hand, when the video application process is activated by the user while connected to the cradle 2, the video is displayed and output from the external monitor regardless of the current style. Further, when “view style” is changed to “open style” while connected to the external monitor, it is switched to video output on the external monitor instead of video output from the mobile screen 20. Conversely, when the “open style” is changed to the “view style”, the video output on the portable screen 20 is switched to the video output from the external monitor. Further, when the connection of the cradle 2 is released, if the style at that time remains “view style”, a horizontally long image is displayed and output from the mobile screen 20, and if it is “open style”, it is output from an external monitor. Instead of the video output, the screen is switched to the vertical video display from the mobile screen 20.
(Example 2)

A second embodiment of the present invention will be described below with reference to FIGS.
In the first embodiment described above, the video application process is activated by a user operation. However, in the second embodiment, an external monitor (PC 3 / fixed television apparatus 4) is connected via the cradle 2. When connected, the video application process is automatically started to instruct video output on an external monitor. In addition, the mobile phone device 1 is configured to perform ON / OFF (off / off) control of the power supply of the external monitor (PC 3 / fixed television device 4) while being connected to the cradle 2.
Here, the same or the same names in both embodiments are denoted by the same reference numerals, the description thereof will be omitted, and the following description will focus on the features of the second embodiment. .

FIGS. 6 and 7 are flowcharts showing the overall operation of the mobile phone device which is started to be executed when the power is turned on in the second embodiment.

If an incoming call / mail is detected in this standby state (YES in step B2), an incoming call process is executed (step B3). Further, in the standby state, it is checked whether or not it is connected to the cradle 2 based on a detection signal from the cradle connection unit 25 (step B4), whether or not there is an operation (step B8), or when any key operation is performed. (YES in step B7) After executing, for example, a telephone call process, a mail creation process, a mail transmission process, etc. as a process corresponding to the operation (step B9), the process returns to the standby state (step B1).

  When the apparatus main body is placed (connected) on the cradle 2 (YES in step B4), it is checked whether there is a self-starting application that is automatically started in response to the cradle connection (step B5). Here, if there is a self-starting application, it is checked whether it is a video application (step B6). If it is another application, the application is started and the process proceeds (step B7). If there is (YES in step B6), the process proceeds to the flow of FIG. 7 to activate the video application (step B10).

  Then, the current style is determined based on the detection signal from the style detection sensor 26 (step B11). If the “view style” is suitable for video display, a horizontally long video is displayed and output from the mobile screen 20 (step B12). ). If the style is other than “view style” (NO in step B11), the power supply of the external monitor is transmitted via the cradle connection unit 25 and the cradle 2 to turn on the power of the PC 3 or the fixed television set 4. After that (step B13), a video output command is given to the external monitor via the cradle 2, and a video signal transmission operation is started (step B14).

  In this state, it is checked whether any key is operated (step B15), whether the connection with the cradle 2 is released based on the detection signal from the cradle connection unit 25 (step B18), or the style detection sensor 26. It is checked whether the current style has been changed based on the detection signal from (step B22). Now, when any key is operated (YES in step B15), if it is an end operation for instructing the end of the video application process (YES in step B16), the above standby state is returned (FIG. 6). Step B1), if it is another operation (NO in Step B16), processing such as audio adjustment, channel switching, and fast-forward playback is performed as the operation corresponding processing (Step B17).

 If the connection with the cradle 2 is released (YES in step B18), it is checked whether the video is being output from the external monitor (step B19). If the video is being output from the external monitor, the external monitor is used instead. Then, switching to video output from the mobile screen 20 is performed (step B20). And after giving a power-off command with respect to an external monitor and turning off the power (step B21), it returns to above-mentioned step B15.

 If the style has been changed (YES in step B22), the process returns to the above-described step B11. When the “view style” is changed to another style (NO in step B11), the video from the mobile screen 20 is displayed. Switching to video output on the external monitor instead of output (steps B13 and B14), but switching to video output from the mobile screen 20 instead of the external monitor when changed to “view style” (YES in step B11) (Step B12).

 As described above, in the second embodiment, the CPU 11 determines the presence / absence of connection to the external monitor (PC 3 / fixed television device 4) via the cradle 2, and displays the video application when connected to the external monitor. By automatically starting and instructing video output on the external monitor and performing output control thereof, video output on the external monitor can be easily realized without any special operation. In this case, the cellular phone device 1 does not need to operate the external monitor by controlling the power supply of the external monitor via the cradle 2. In addition, the second embodiment has the same effects as the first embodiment described above.
