Thus, since a high-resolution image can be displayed without being restricted by the screen size and screen resolution of the display attached to the portable information communication device, it is possible to browse the Web page for PC without any trouble.

  However, as disclosed in Patent Literature 1 and Patent Literature 2, even if the portable information communication device connects an external device with a large screen and / or high resolution external display means, for example, on the Web server side, for example, If the setting for rejecting access from a portable information communication device such as a mobile phone to a website for PC is kept, the situation in which a web page constituting the website cannot be browsed does not change.

On the other hand, for example, on the website side, based on the model information of the portable information communication device that has been accessed, whether the portable information communication device is “a model having a function with external display means or a model that is not so” It is also possible to use a method of determining and performing access management based on the determination result. However, in such a system, the “automatic distribution function” currently performed on many websites, that is, the “automatic distribution function” is a function of CGI (Common Gateway Interface) or PHP (Hypertext Preprocessor). Use this function to sort the data file (markup document file) to be sent based on the terminal information of the access source (usually information on which PC is a mobile phone, and if a mobile phone is a mobile phone of which communication company) Cannot fit.
Because, in the case of the techniques disclosed in Patent Document 1 and Patent Document 2, even when an external device with external display means is connected to the portable information communication device, the portable information communication device is used alone. Even if the mobile information communication device itself does not change, the model information of the mobile information communication device alone will indicate that “the same data file is transmitted regardless of whether an external device with an external display is connected or not. For this reason, even though the portable information communication device is used alone, a data file that can only be grasped by a large screen and / or high-resolution display means is transmitted, or portable information Despite connecting an external device with external display means to the communication device, the amount of information is small assuming a small screen and low screen resolution. It caused a mismatch that over datafile is or is sent.

In particular, when the mobile phone 1 is used alone, the user agent character string includes a character string that can identify that “the external device with the external display means is not connected”.
Note that, as described above, communication radio signal exchange between the mobile phone 1 and the base station 91 is performed by a method such as CDMA when the base station 91 is a base station of a cellular network for mobile communication. Thus, when the base station 91 is a wireless LAN base station / access point, it is executed by communicating with a system such as DSSS or OFDM).

On the other hand, the Web server 92 stores a plurality of markup document files having substantially the same description contents but different layout formats, and a plurality of image data files having substantially the same display object but different resolution. In addition, by using a function such as CGI or PHP, whether an external device with external display means is connected to the mobile phone 1 based on the user agent character string included in the HTTP request from the mobile phone 1 It is determined whether or not a plurality of markup document files and image data files having higher compatibility are selected as follows, and then transmitted via the Internet 9.
That is, when the mobile phone 1 is used as it is as described above, and a user agent character string including a character string that can identify that “an external device with an external display means is not connected” is transmitted Among the plurality of markup document files, a markup document file having a fixed-width layout with a narrower line feed width (more specifically, a fixed-width layout with a screen horizontal resolution (240 pixels) of the LCD panel 15A) or Send a liquid layout markup document file. If the markup document file is linked to the image data file, an image data file with a lower resolution is transmitted among the plurality of image data files.

The data file is transmitted as a digital electric signal from the Web server 92. The digital electric signal is converted into a radio signal by the base station 91 and transmitted, and the radio signal is transmitted to the communication antenna 111A and the RF transceiver 111B. The markup document file constituting the Web page and its link file can be acquired by being finally received as a digital signal by the central processing circuit 10A via the baseband processor 11 and the bus 19. .
Then, the central processing circuit 10A generates a drawing command for a page image having the same number of horizontal pixels as the screen horizontal resolution of the LCD panel 15A according to the browser program stored in the flash memory 14A, and the drawing command is output to the graphic controller. Send to 10B. Based on the drawing command, the graphic controller 10B generates bitmap data on a virtual screen having a sufficiently large logical resolution, writes it into the VRAM_10C, and displays it on the LCD panel 15A, and has the same resolution as the screen resolution of the LCD panel 15A. Bitmap data describing an image having the same is cut out from the VRAM_10C and transmitted to the LCD driver 15B. The LCD driver 15B drives each pixel constituting the screen of the LCD panel 15A based on the bitmap data, and finally the screen image corresponding to the Web page is displayed on the screen as necessary. A full-screen image combining menu displays and the like displayed at the top and bottom of the screen is displayed on the LCD panel 15A.

  FIG. 3 is displayed on the attached display panel (LCD panel 15A in FIG. 1) when the portable information communication apparatus according to the first embodiment of the present invention accesses a Web server having the function of calculating the optimum route. It is an image figure for demonstrating the page image of an input screen.

This page is a destination input page written in a simplified markup language such as CHTML or WML. Enter a character or numeric character in the blank field and click the “Search” or “List” button. By doing so, it has only a relatively simple function of transitioning to the next page that defines the destination in more detail. For this reason, it is possible to easily input / operate by operating a dial key or a jog key in the key operation unit 16A of the mobile phone 1.
In addition, since a liquid layout is adopted as a layout format and no link is made to an image data file or the like, a page can be viewed on the LCD panel 15A having a QVGA size without horizontal scrolling.

The mobile phone 1 not only acquires image data as a link file of a markup document file by the HTTP request as described above, but also FTP (File
An image data file and / or an audio data file can be acquired from the Web server 92 by a transfer protocol request, and the data file can be temporarily stored in the flash memory 14A.
When the cellular phone 1 reproduces the image data file and / or the audio data file stored in this way, the central processing circuit 10A stores in the flash memory 14A based on the data input by operating the key operation unit 16A. By accessing and reading out the data file and performing necessary processing, a rendering command is output to the graphic controller 10B, and a digital audio signal is output to the CODEC_18C via the baseband processor 11. As a result, an image can be displayed on the LCD panel 15A, audio can be output from the speaker 18B, or a movie can be reproduced as a combination of image data and audio data as a moving image.
Note that image data and movies that are moving images can be reproduced not only by reading the data file once stored as described above, but also by a streaming method in which reproduction is performed simultaneously while receiving data.

MPEG (Moving Picture) is used to save video image data.
Experts Group) -1, MPEG-2, MPEG-4 and other MPEG standard formats. When saving still image data, save in BMP, TIFF, JPEG, GIF and PNG formats. Is done. For audio data, the WAVE format, MP3 (MPEG
Audio Layer 3), AIFF (Audio Interchange File Format), ATRAC3 (Adaptive TRansform)
Saved in a format such as Acoustic Coding 3).
However, in any case, since the capacity of the flash memory 14A is limited, for example, there is a restriction in storing a movie or the like for a long time.
When a removable storage medium such as a memory card is added as a storage means, not only image data and / or audio data acquired from the Web server, but also data files stored in the removable storage medium Can be reproduced in the same way.

  The above is the outline of the function when the mobile phone 1 is used alone. The mobile phone 1 includes the external connection terminal portion A_13D for connecting to the connection unit 3, and the external connection terminal on the mobile phone 1 side. The mobile phone 1 and the connection unit 3 are made to operate as an integrated information communication system by connecting the part A_13D and the external connection terminal B_33D constituting the interface part B_33 on the connection unit 3 side via the connection cable 2. Will be able to.

  FIG. 4 shows a configuration in which a portable information communication device and a portable information communication device connection unit according to the first embodiment of the present invention are connected, and an external display device and an external input device are connected to the connection unit. 2 is an external view for explaining the configuration of the information communication system, and particularly, a case where the portable information communication device is a mobile phone.

In this embodiment, the connection unit 3 has an insertion port 33D1 into which the mobile phone 1 is inserted. By inserting the mobile phone 1 into the insertion port 33D1, the external connection terminal portion A_13D (shown in FIG. 4) in the mobile phone 1 is obtained. And the external connection terminal portion B_33D of the interface portion B_33 (not shown in FIG. 4) in the connection unit 3 comes into contact with each other, and as a result, the cellular phone 1 and the connection unit 3 are connected (hence, here) Connection cable 2 is not required).
The connection unit 3 has an external input connection terminal 36D for connecting the external keyboard 61 and the mouse 62, and by inserting the connectors of the external keyboard 61 connection cable and the mouse 62 connection cable into these, Can be connected to the connection unit 3. Further, the connection unit 3 also has a connection terminal (not shown in FIG. 4) for connecting the external display device 5, and the connector of the cable for connecting the external display 5 is connected to the connection terminal on the external display device 5 side. By connecting to (not shown in FIG. 4), the external display device 5 can be connected to the connection unit 3.

At this time, an interface between the connection unit 3 and the external display device 5 and the external input device (external keyboard 61 and mouse 62) is set to DVI (Digital
Connectors and cables can be procured at low cost by conforming to general-purpose standards such as Visual Interface (USB) and Universal Serial Bus (USB). Alternatively, instead of connecting the connection cable or external connection terminals as described here by direct contact, Bluetooth (registered trademark) or IrDA (Infrared)
It is also possible to use wireless means such as the Data Association standard.

On the other hand, the HDD_34, the interface unit B_33, the interface unit C1_35, and the interface unit C2_36 (all of which are not shown in FIG. 4) are housed in the housing of the connection unit, and these components are shown in FIG. Connected to the street.
Further, the connection unit 3 also has a commercial power plug 37C, and the AC power supplied by inserting the commercial power plug 37C into the outlet 7 of the commercial AC power source is included in the AC / DC circuit 37B (shown in FIG. 4). The connection unit 3 can be driven by the direct-current power obtained by the conversion at the same time, and the built-in rechargeable battery 17 (not shown in FIG. 4) of the mobile phone 1 can be charged.

  In the following description, the screen resolution of the external display device 5 (LCD) is described as a VGA size (number of horizontal pixels × number of vertical pixels = 640 × 480 pixels) in principle. However, the resolution is higher than that. May be.

Now, when the active mobile phone 1 and the active connection unit 3 are connected, the active mobile phone 1 is connected to the connection unit 3 and the connection unit 3 is activated, or the mobile phone 1 is active When the mobile phone 1 is activated by connecting to the connection unit 3, the central processing circuit 10A of the mobile phone 1 detects from the connection unit 3 that the connection unit 3 is connected (hereinafter referred to as connection). Abbreviated as a detection signal) and screen resolution data of the external display device 5 connected to the interface unit C1_35 of the connection unit 3 via the external connection terminal unit B_33D, the connection cable 2, the external connection terminal unit A_13D and the bus 19. Receive.
In the following, for simplicity of explanation, when the connection unit 3 is in operation, the external display device 5 and the external input device (external keyboard 61 and mouse 62) that are in operation are always connected. It is assumed that “detection that the connection unit 3 is connected” includes detection that these peripheral devices are connected.

  When the central processing circuit 10A of the mobile phone 1 receives the connection detection signal, the central processing circuit 10A replaces the image drawing command corresponding to the screen horizontal resolution or screen resolution of the LCD panel 15A with an LCD. An image drawing command having a resolution larger than the screen resolution of the panel 15A is generated and transmitted to the graphic controller 10B. Further, the central processing circuit 10A generates a transmission command for instructing the TMDS transmitter 13A to transmit the bitmap data cut out from the VRAM_10C to the LCD driver 15B together with the drawing command described above. The instruction is transmitted to the graphic controller 10B.

  Based on the drawing command received from the central processing circuit 10A, the graphic controller 10B generates bitmap data on a preset virtual screen and writes it into the VRAM_10C. Furthermore, the graphic controller 10B has the same resolution as the screen resolution of the external display device 5 based on the screen resolution data of the external display device 5 obtained from the central processing circuit 10A, and is displayed on the screen of the external display device 5. Is extracted from VRAM_10C. Based on the transmission command received from the central processing circuit 10A, the bitmap data is transmitted to the TMDS transmitter 13A. The TMDS transmitter 13A transmits the bitmap data to the connection unit via the external connection terminal unit A_13D. 3 is transmitted to the interface part B_33 of 3 by the TMDS transmission method.

Here, the whole of the external connection terminal A_13D added to the TMDS transmitter 13A corresponds to the interface means A in the “claims”.
In this embodiment, the bitmap data is transferred from the cellular phone 1 to the connection unit 3 by the TMDS transmission method. In addition, digital RGB, LVDS (Low DS)
Voltage Differential Signaling (or LDI (LVDS Display Interface)) and GVIF (Gigabit
It is also possible to transfer using a transmission method such as Video InterFace.

  In the connection unit 3, the bitmap data received / transferred by the interface unit B_33 is received by the interface unit C1_35 having the TMDS receiver function, and is transmitted to the external display device 5 after performing necessary processing. On the screen of the external display device 5, an image having a resolution corresponding to the screen resolution is displayed.

  The functions of the central processing circuit 10A, the graphic controller 10B, the TMDS transmitter 13A, the interface unit B_33, the interface unit C1_35, and the like described here are not limited to the flash memory 14A or the like even when browsing a Web page as described later. This is basically the same whether the image data or movie stored in the storage means / medium is reproduced or the image data or movie that is a moving image is reproduced.

  When the central processing circuit 10A of the mobile phone 1 receives the connection detection signal, the central processing circuit 10A receives an input signal from the key operation unit 16A of the mobile phone 1 to the key input controller 16B. An input source instruction signal is output so that only an input signal from the external keyboard 61 or mouse 62 connected to the interface unit C2_36 of the connection unit 3 is received. As a result, the user can input data by operating the external keyboard 61 or the mouse 62, which is a full keyboard, instead of the operation at the key operation unit 16A of the mobile phone 1 in which the character input operability is poor. become able to.

Further, the central processing circuit 10A of the mobile phone 1 is based on the data input by operating the external keyboard 61 or the mouse 62, and instead of accessing the flash memory 14A as described above, the bus 19, the external connection terminal unit By accessing HDD 34 via A_13D, connection cable 2 and interface unit B_33 of connection unit 3, bitmap data and digital audio data can be written as a compressed data file as needed, or data file can be read out By performing necessary processing, the rendering command is output to the graphic controller 10B, and the digital audio signal is output to the CODEC_18C via the baseband processor 11. Further, the central processing circuit 10A can read out the data file stored in the flash memory 14A and store it in the HDD 34 via the bus 19, the external connection terminal portion A_13D, and the interface unit B_33 of the connection unit 3. .
At this time, since the capacity of the HDD 34 can be much larger than that of the flash memory 14A, for example, it is possible to save a movie for a long time and a number of music files without restriction.

The designation (switching) of the transmission destination of the bitmap data generated by the graphic controller 10B and the designation (switching) of the data input source to the central processing circuit 10A are based on the received connection detection signal as described above. For example, it may be configured to be performed by manual operation of the key operation unit 16A of the mobile phone 1, for example.
The designation of the resolution of the image described by the bitmap data output to the external display device 5 is not only automatically performed based on the received screen resolution data of the external display device 5 as described above, For example, a configuration in which an image indicating resolution options is displayed on the screen of the LCD panel 15A or the external display device 5, and a resolution that matches the screen resolution of the external display device 5 is selected by the external keyboard 61 or the mouse 62 is used. It can also be. Alternatively, such a selection unit is not provided, and the resolution of the image described by the bitmap data output to the external display device 5 can be fixed to, for example, the VGA size.

  In this embodiment, even when the mobile phone 1 is connected to the connection unit 3, the audio data or movie stored in the storage means / medium such as the flash memory 14A is played, or the audio data or movie is streamed. Audio is output from the speaker 18B on the mobile phone 1 side, but after adding interface means necessary for both the mobile phone 1 and the connection unit 3, and adding an audio decoder to the connection unit 3, By connecting a high-performance external speaker to the connection unit 3, high-quality sound can be output from the external output.

  FIG. 5 shows a configuration in which the portable information communication device according to the first embodiment of the present invention is connected to the portable information communication device connection unit, and then the external display device and the external input device are connected to the connection unit. It is explanatory drawing for demonstrating the exchange of information between the information communication system and the Web server connected to the internet.

Even when the user accesses the Web server 92 connected to the Internet 9 and browses a Web page using the information communication system configured as described above, the user agent character string is displayed in the header portion from the mobile phone 1. An HTTP request containing is sent. However, in this case, unlike the case where the mobile phone 1 is used alone, the user agent character string includes a character string that can identify “an external device with an external display means is connected”. .
At this time, the character string corresponding to the “screen resolution data of the external display device 5” received by the central processing circuit 10A from the connection unit as described in [0062] may be included in the user agent character string.

  On the other hand, in the Web server 92, it is the same to select and transmit a file having higher compatibility based on the user agent character string included in the HTTP request from the mobile phone 1, but in this case, Of the multiple markup document files, a fixed-width layout markup document file with a wider line feed width (more specifically, the same as the screen horizontal resolution (640 pixels) of the external display device 5 (LCD)) Send a markup document file with a wider fixed-width layout. If the markup document file is linked to the image data file, an image data file with a lower resolution is transmitted among the plurality of image data files.

The data file goes through the process described in [0051], and is finally received as a digital signal by the central processing circuit 10A, thereby obtaining a markup document file and its link file constituting the Web page. can do. Then, the central processing circuit 10A generates a page image rendering command having the same number of horizontal pixels as the fixed width of the markup document file in accordance with the browser program stored in the flash memory 14A, and transmits it to the graphic controller 10B.
The graphic controller 10B, the TMDS transmitter 13A, the interface unit B_33, the interface unit C1_35, etc. operate as described in [0064] and [0066], and finally the markup document file is displayed on the screen of the external display device 5. A page image corresponding to the link file is displayed. At that time, particularly when the fixed width of the markup document file is larger than the screen resolution of the external display device 5, depending on the data input by operating the key responsible for the screen scroll function in the key operation unit 16A. When the central processing circuit 10A1 changes the drawing command, the bitmap data cut out from the VRAM_10C gradually transitions on the virtual screen, and as a result, the page image is scroll-displayed on the screen of the external display device 5.

  FIG. 6 shows a configuration in which the portable information communication device according to the first embodiment of the present invention is connected to the portable information communication device connection unit, and then the external display device and the external input device are connected to the connection unit. FIG. 5 is an image diagram for explaining a page image of an input screen displayed on an external display device when the information communication system accesses a Web server having a function of calculating an optimum route.

This page is a page for entering the destination as in FIG. 3, but after entering a character or numeric character in the blank, click the “Search” or “List display” button to move to the next page. In addition to the same function as 3, it has a relatively complicated function of transitioning to the map image page of the prefecture by clicking the image data of the map of Japan in each prefecture. For this reason, this page is described in full-spec HTML, and the layout format has a fixed width of 640 pixels in the horizontal resolution.
If such a page is to be browsed by the mobile phone 1 alone, the LCD panel 15A must repeat horizontal scrolling many times, and the key operation unit 16A cannot perform sufficient input operations. According to the information communication system configured as described above, the screen of the external display device 5 can be browsed without horizontal scrolling, and can be easily input by the external input device (the external keyboard 61 and the mouse 62).

FIG. 2 is a block diagram, and particularly describes a case where the portable information communication device is a mobile phone.

The function of the mobile phone 1 in this embodiment is exactly the same as the function of the mobile phone 1 in the first embodiment as long as it is used alone. On the other hand, the mobile phone 1 is connected to the external input / output unit 4 via the connection cable 2 instead of the connection unit. In this case, however, the central processing circuit 10A receives the screen resolution data of the external display device instead. Except for receiving the screen resolution data of the external LCD panel 45A of the external input / output unit 4, the basic functions are the same.
On the other hand, the external input / output unit 4 also includes an external LCD panel 45A and an external key operation unit 461 as a part of the external display device and the external keyboard instead of externally connecting the external display device and the external keyboard.

That is, inside the casing in which the external key operation unit 461 and the external touch pad 462 are provided on the top surface, circuits that constitute the interface unit D_43 not shown in FIG. 8, circuits such as the TMDS receiver 45D and the scan converter 45C, And HDD 44 are housed. The casing and the external LCD panel 45A are connected by a hinge, and an external LCD driver 45B (not shown in FIG. 8) is housed in the frame portion of the external LCD panel 45A.
In addition, an external connection terminal portion D_43D for connecting the connection cable 2 and a power cable for connecting the AC / DC circuit 47B are connected to the rear side surface (not shown in FIG. 4) of the housing. Terminal portions are provided.

  When the information communication system configured by connecting the mobile phone 1 and the external input / output unit is used for data communication / processing, the central processing circuit 10A of the mobile phone 1 uses the connection detection signal of the external input / output unit 4 and the external When the screen resolution data of the external LCD panel 45A in the input / output unit 4 is received, the graphic controller 10B generates bitmap data describing an image having an appropriate resolution when used for data communication / processing, Commands the TMDS transmitter 13A to transmit. The bitmap data transmitted according to the drawing command and the transmission command is received by the external connection terminal portion D_43D constituting the interface portion D_43 of the external input / output unit 4 via the external connection terminal portion A_13D in the mobile phone 1. . The bitmap data is subjected to necessary processing by the TMDS receiver 45D and the scan converter 45C and then transmitted to the external LCD driver 45B. The external LCD driver 45B includes each pixel constituting the screen of the external LCD panel 45A. Is driven, a screen image is displayed on the external LCD panel 45A.

Note that the external input / output unit 4 of this embodiment also has a commercial power plug 47C as in the connection unit 3 of the first embodiment, and ac power supplied from the commercial power plug 47C is attached.

(Third embodiment)
FIG. 9 is a block diagram for explaining the configuration and functions of a portable information communication device, a portable information communication device connection unit according to a third embodiment of the present invention, and an in-vehicle information communication system configured by connecting the two. In particular, the case where the portable information communication device is a mobile phone is described.

  In this embodiment, the mobile phone 1 can be used alone for navigation in addition to the application in which the mobile phone 1 in the first and second embodiments is used. An image or the like is displayed on the LCD panel 15A which is an attached display panel.

The functions when the cellular phone 1 in this embodiment is used for voice communication, data communication / processing, or image data and / or voice data storage / playback, except for the following, The function is the same as that of the cellular phone 1 in the first and second embodiments.
That is, in the cellular phone 1 in the first and second embodiments, the exchange of signals between the public network and the baseband processor 11A is performed via the communication antenna 111A and the RF transceiver unit 111B. Thus, in the mobile phone 1 in this embodiment, this is performed via the shared antenna 113A, the duplexer 113D, and the RF transceiver 111B.
Here, the common antenna 113A converts both the communication radio wave signal and the GPS signal into an electric signal and then transmits the electric signal to the duplexer 113D. The duplexer 113D converts the electric signal obtained by converting the communication radio wave signal and the GPS signal. The transmitted electric signals are distributed to the RF transmitting / receiving unit 111B and the GPS down converter 113B, respectively, and transmitted. The whole of the shared antenna 113A, the duplexer 113D, the RF transceiver unit 111B, and the GPS down-converter 113B plus an AD / DA conversion unit 113C, which will be described later, corresponds to the wireless communication means in the “claims” section. .

  FIG. 10 shows an exchange of information between an embodiment of the portable information communication apparatus according to the third embodiment of the present invention and a Web server connected to the Internet, particularly a Web server for a road traffic information providing system. It is explanatory drawing for demonstrating the exchange of information between.

  When a user accesses a general Web server 92 connected to the Internet 9 using the mobile phone 1 in this embodiment and browses a Web page corresponding to the stored markup document file, the function of the mobile phone 1 and the like The exchange of signals between the mobile phone 1 and the base station 91 / Web server 92 is performed via the communication antenna 111A / RF transceiver 111B, via the duplexer 113D / RF transceiver 111B. The functions and the like in the first and second embodiments are the same except that they are performed.

  In this embodiment, the mobile phone 1 can be used for navigation by accessing a Web server 93 for a road traffic information providing system connected to the Internet 9. The functions and the like of the mobile phone 1 when used for navigation are as follows.

  First, the GPS signal received by the common antenna 113A is converted into a digital GPS signal via the duplexer 113D, the GPS down converter 113B, and the AD / DA converter 113C, and is sent to the central processing circuit 10A via the bus 19. Sent. The central processing circuit 10A generates its own position data by processing the digital GPS signal based on a program stored in the flash memory 14A. On the other hand, the user can input character data (hereinafter abbreviated as destination data) specifying the destination by operating the key operation unit 16A, and the character data is converted into a digital signal by the key input controller 16B. And received by the central processing circuit 10A.

The central processing unit 10A processes the self-location data generated above and the destination data received via the key input controller 16B, and converts the digital data into a digital signal together with a transmission request such as a markup document file and transmits it. And finally, it is received as a digital signal by the Web server 93 for the road traffic information providing system connected to the Internet 9 through the process described in [0048].
At this time, the transmission request is transmitted as an HTTP request including a user agent character string, and the user agent character string includes a character string capable of identifying that “the external device with the external display means is not connected”. It is.

On the other hand, the Web server 93 for the road traffic information provision system stores the following two types of map image data file sets covering areas in Japan (the divided mesh sizes of the map display area are the same for both). ).
(1) A set of map image data files that describe only arterial roads, have little character information such as place names / facility names, and have low original resolution (2) List not only arterial roads but also narrow roads, place names / facility names, etc. A set of map image data files that originally contain a large amount of character information and have a high resolution, and the Web server 92 uses the functions such as CGI and PHP, so that the user included in the HTTP request received from the mobile phone 1 Based on the agent character string, it is determined whether or not an external device with an external display means is connected to the mobile phone 1, and a set having higher compatibility among the above set of map image data files is as follows: Select
That is, when the mobile phone 1 is used as it is as described above, and a user agent character string including a character string that can identify that “an external device with an external display means is not connected” is transmitted The above set (1) is selected. Then, based on the own position data received from the mobile phone 1, a map image data file including the current position of the mobile phone 1 is selected from the set (1).

Further, the Web server 93 for the road traffic information providing system calculates the optimum route from the current position of the mobile phone 1 to the destination based on the own position data and the destination data received from the mobile phone 1. Then, a navigation image data file is generated by superimposing the optimum route and a mark indicating the current position of the mobile phone 1 on the map image in the map image data file selected as described above, and the data file is converted into a digital signal. And send it to the Internet 9.
The central processing circuit 10A of the mobile phone 1 acquires the navigation image data file through the process as described in [0051], transmits a navigation image drawing command to the graphic controller 10B, and finally the LCD panel. A navigation image is displayed at 15A.

The divided mesh size in the map image data file set stored in the Web server 93 for the road traffic information providing system is that the user who holds the mobile phone 1 or the vehicle on which the mobile phone 1 is mounted moves. Even in such a case, the mobile phone 1 is set so as to cover an area range wider than the area range that can be displayed on the LCD panel 15A at a time so that the mobile phone 1 does not frequently receive the transmission request of the map information data file. For this reason, the original resolution of the map information data file is naturally larger than the screen resolution of the LCD panel 15A, and the central processing circuit 10A has a high-resolution self-location map image in which the self-location information is superimposed on the high-resolution map image. The drawing command is transmitted to the graphic controller 10B, and the graphic controller 10B once writes the bitmap data describing the high-resolution self-location map image in the VRAM_10C and then describes the image having the same resolution as the screen resolution of the LCD panel 15A. The bitmap data to be cut out from the VRAM_10C and transmitted to the LCD driver 15B.
At this time, the displayed map image is not only scrolled by the operation of the jog key, but if the automatic display mode is selected in the mobile phone 1, the central processing circuit 10A adjusts the movement of the user or the vehicle. By continuing to update the drawing command, the mobile phone 1 is automatically scrolled so that the current position of the mobile phone 1 is always located at the center of the LCD panel 15A.

  In this embodiment, the destination information is input as character data by the key operation unit 16A. However, the destination information can be input by the following method. That is, for example, after the destination option is displayed on the LCD panel 15A, the destination can be selected from the options by operating the jog key responsible for the pointing function in the key operation unit 16A, or on the LCD panel 15A. A map image including the destination can be displayed, and a point in the map can be designated as the destination by operating the jog key. Further, by storing a voice recognition program in the flash memory 14A and further adopting a central processing circuit 10A having a necessary voice data processing capability, destination information can be input as voice data by the microphone 18A. Is also possible.

  Furthermore, the Web server 93 for the road traffic information providing system displays the traffic congestion status in addition to the current position and the optimum route of the mobile phone 1 based on the traffic traffic information such as the traffic congestion collected by itself. A navigation image data file can be generated and transmitted. In addition to the navigation image data file, an audio data file that guides the optimum route and explains road traffic information such as traffic conditions is transmitted. On the other hand, the cellular phone 1 receives the audio data file. By reproducing the stream, it is possible to finally output the guidance voice / explanatory voice from the speaker 18B.

  FIG. 11 shows an attached display panel (LCD panel 15A in FIG. 9) when the portable information communication device according to the third embodiment of the present invention accesses a Web server having a function of creating and transmitting a navigation image. It is an image figure for demonstrating the navigation image displayed on.

In this navigation image, the current position of the mobile phone 1 is indicated by an arrow in the center of the figure, and the optimum route to the destination is indicated by a thick line on the road.
[0092] As described in [0092], when the mobile phone 1 is used alone, the map received from the Web server 93 for the road traffic information providing system is a map with originally low resolution included in the set (1). Since the navigation image data file is based on the image data file, the map display area displayed per size of the LCD panel 15A is relatively large. On the other hand, the displayed road is limited to the main road. In addition, the displayed place names are limited to road names.

At this time, when the user who holds the mobile phone 1 or the vehicle equipped with the mobile phone 1 moves in the direction of the arrow, the arrow indicating the current position is always displayed on the screen by the automatic display mode function described in [0094]. The map image scrolls from the top to the bottom so as to be located at the center of the map.
FIG. 11 shows an example in which the self-location map image is displayed on the entire screen on the attached display panel (LCD panel 15A in FIG. 9). An example of display is also possible.

The bottom of the insertion port 43D1 for inserting the telephone 1 is connected by a connection cable 2 (not shown in FIG. 12). Therefore, by inserting the mobile phone 1 into the insertion port 43D1 and connecting the external connection terminal portion A_13D on the mobile phone 1 side and the external input / output terminal portion B_33D on the external input / output unit 4 side via the connection cable 2. , It will function as an integrated in-vehicle information communication system.

  Further, in this embodiment, the in-vehicle information communication system configured by connecting the mobile phone 1 and the external input / output unit 4 has an external rechargeable battery 87 (not shown in FIG. 12) mounted on the automobile. It operates with DC power supplied from That is, the DC power stored in the external rechargeable battery 87 is not only used for the operation of the external input / output unit 4, but also the built-in rechargeable battery of the mobile phone 1 via the external connection terminal portion B_33D and the external connection terminal portion A_13D. 17, and once stored, it is used for the operation of the mobile phone 1.

In the following, the external LCD touch panel 456 is a WVGA (Wide Video).
The description will be made assuming that the screen resolution is (Graphics Array) size (the number of horizontal pixels × the number of vertical pixels = 800 × 480 pixels), but other resolutions may be used.

The exchange of signals such as bitmap data between the mobile phone 1 and the external input / output unit 4 in the in-vehicle information communication system of this embodiment is the same as that in the second embodiment.
On the other hand, in the external input / output unit 4, an image is displayed as follows. That is, in the external input / output unit 4, the bitmap data received / transferred by the interface unit D_43 is received by the interface unit C1_35, and after necessary processing is performed by the TMDS receiver 45D, it is transmitted to the external LCD touch panel 456, As a result, on the screen of the external LCD touch panel 456, an image having a resolution corresponding to the screen resolution, that is, a high resolution image having a resolution larger than the screen resolution of the LCD panel 15A is displayed.

  FIG. 13 shows an embodiment of an in-vehicle information communication system configured by connecting a portable information communication device according to a third embodiment of the present invention and an external input / output unit for the portable information communication device, and is connected to the Internet. Explaining the exchange of information with the Web server, particularly the exchange of information with the Web server for the road traffic information providing system, and the function of one embodiment of the road traffic information providing system according to the present invention It is explanatory drawing for demonstrating.

  When a user accesses a general Web server 92 connected to the Internet 9 using the in-vehicle information communication system in this embodiment and browses a Web page corresponding to a stored markup document file, the operation of each component The exchange of signals between the mobile phone 1 and the base station 91 / Web server 92 is performed via the duplexer 113D / RF transceiver 111B instead of being performed via the communication antenna 111A / RF transceiver 111B. To be performed, to be displayed on the external LCD touch panel 456 instead of being displayed on the external display device 5, and to input character data or the like using an external input device (external keyboard 61 and mouse 62). Instead of being performed on the external key touch panel 456 or the external key operation unit 461 arranged on the frame portion of the external LCD touch panel 456 Except that takes place I like, is basically the same as the operation of each component of the information communication system according to the first embodiment.

Among these, in particular, details of input of character data and the like using the external LCD touch panel 456 are as follows. In other words, the external LCD touch panel 456 has a touch panel function that allows data to be input by touching the surface of the panel. Further, the external LCD touch panel 456 can switch the screen by a key operation on the outer edge of the external LCD touch panel 456. A possible external key operation unit 461 is provided. Thus, the user can input data by operating the external key operation unit 461 and the touch operation of the external LCD touch panel 456. The input data passes through the interface unit D_43, the external connection terminal unit A_13D, and the bus 19. Then, it is transmitted to the central processing circuit 10A.
When the central processing circuit 10A of the mobile phone 1 receives the connection detection signal, the central processing circuit 10A accepts an input signal from the key operation unit 16A of the mobile phone 1 to the key input controller 16B. First, an input source instruction signal for accepting only an input signal from the external LCD touch panel 456 or the external key operation unit 461 of the external input / output unit 4 is output.

On the other hand, when the in-vehicle information communication system is used for car navigation, in addition to the operation when accessing the general Web server 92, the location information and the purpose are stored in the Web server 93 for the road traffic information providing system. An operation for transmitting terrestrial data is added, which is the same as the operation when the mobile phone 1 is used alone.
However, when the central processing circuit 10 receives the connection detection signal, that is, when the mobile phone 1 is used as a part of the in-vehicle information communication system, the mobile phone 1 is used alone. Unlike the above, the user agent character string transmitted from the mobile phone 1 includes a character string that can identify “an external device with external display means is connected”. Correspondingly, the Web server 93 for the road traffic information providing system selects the set (2) described in [0092] and receives from the set (2) from the mobile phone 1. A map image data file including the current location of the mobile phone 1 is selected based on the self location data.

When the mobile phone 1 is used as a part of the in-vehicle information communication system, the audio input and the audio output as described in [0095] and [0096] are externally attached to the external input / output unit 4. This can be realized by using the microphone 48A and the external speaker 48B.
That is, when the central processing circuit 10A of the mobile phone 1 receives the connection detection signal, the central processing circuit 10A and the baseband processor 11 change the input / output destination of the digital audio data from the CODEC_18C to the external connection terminal portion A_13D. And switch to the external CODEC_48C via the interface unit D_43. As a result, the external microphone 48A, the external speaker 48B, the external CODEC_48C, and the baseband processor 11 can exchange digital audio via the bus 19 and the interface means, and the external microphone 48A and the external speaker 48B are used. Voice input / output can be realized.
This voice external input / output function can be used during voice calls and during playback of voice data and movies stored in the HDD_44. In particular, in a voice call, a user can perform a voice call in a hands-free manner without making a call while holding the mobile phone 1 that is prohibited by the Road Traffic Law even while driving a vehicle. There is an advantage that can be performed.

Further, the external input / output unit 4 can receive the speed data of the vehicle from the speedometer 81 mounted on the vehicle via the interface unit C3_49, and the speed data is converted into a digital signal by the interface unit C3_49. Then, it is transmitted to the mobile phone 1 via the interface part D_43 and the external connection terminal part A_13D. Then, the central processing circuit 10A of the mobile phone 1 generates a digital signal including its own position information and speed information, and the digital signal undergoes a process as described in [0048], and finally the Internet 9 Is received as a digital signal by the web server 93 for the road traffic information providing system connected to the.
As a result, the web server 93 for the road traffic information providing system can obtain data in which position information and speed information are set from the in-vehicle information communication system. And if the number of vehicles on which the in-vehicle information communication system of this embodiment is traveling increases in a certain area, the traffic jam situation in the area can be grasped very accurately, and If this information can be fed back to the in-vehicle information communication system, the convenience of the driver of the vehicle equipped with the in-vehicle information communication system will be enhanced.

FIG. 13 is an image diagram for explaining a navigation image displayed on a display screen (external LCD touch panel 456 in FIGS. 9 and 12) of an external input / output unit when a Web server having a function is accessed.

Also in this navigation image, the current position of the mobile phone 1 is indicated by an arrow in the center of the figure, and the optimum route to the destination is indicated by a thick line on the road.
As is clear from comparison with FIG. 11, the external LCD touch panel 456 displays a map image that covers a wider area than that displayed on the LCD panel 15A. In addition, as described above, when the mobile phone 1 is used as a part of the in-vehicle information communication system, receiving from the Web server 93 for the road traffic information providing system is included in the set (2). Since it is a navigation image data file based on the map image data file, not only the main road but also the narrow road is displayed. In addition to the road name, the place name / lot number, facility name, intersection name, etc. are also displayed. ing.

As in the case of FIG. 11, when the user who holds the mobile phone 1 or the vehicle on which the mobile phone 1 is mounted moves in the direction of the arrow, the function of the automatic display mode described in [0094] The map image scrolls from the top to the bottom so that the arrow indicating is always located at the center of the screen.
