Description

  The present invention relates to a portable information communication device such as a cellular phone, a connection unit used with the portable information communication device, and an external input / output unit used with the portable information communication device.

Mobile phone terminal devices including PHS (Personal Handyphone System) having a function of transmitting and receiving data by wireless communication due to recent advances in electronic / information technology and communication technology (hereinafter referred to as “mobile phone terminal devices including PHS”) Mobile information communication devices such as PDA (Personal Digital Assistants) and PDA (Personal Digital Assistants) have become multifunctional, and not only send and receive e-mail functions, but also markup document files and their A browser function for browsing a web page by displaying characters and images on an attached display, which is usually a liquid crystal display, after obtaining a link file and appropriately laying out the file has become standard.
The “markup document file” as used in the “specification” and “claims” is described in HTML (Hyper Text Markup Language), XML (eXtensible Markup Language) or a markup language based on them. Means a document file created.

  In addition, after downloading the game program from the web server and storing it in a storage means such as a flash memory, operating the program by operating the attached key operation unit and manually inputting necessary data Many mobile phones are also possessing game functions for enjoying changes in images displayed on a display. Further, some mobile phones have a TV tuner function for receiving television broadcast radio signals (hereinafter abbreviated as TV broadcast signals) and displaying TV program images on an attached display. It has become. In particular, with regard to the TV tuner function, terrestrial digital broadcasting for portable information communication devices is scheduled to start. By combining this digital TV tuner function and the above-described browser function on a mobile phone, It is expected that it will be possible to provide services that take advantage of the characteristics of both simultaneous radio broadcasting and personal and interactive Internet communications.

  Under such circumstances, it is considered that the display function of images including characters and videos will become more and more important in the future in portable information communication devices such as mobile phones. However, in a portable information communication device such as a mobile phone, since its portability is important, a large size display cannot be attached. For this reason, in the case of a mobile phone, the screen size is about 2.5 inches at the maximum, and the screen resolution is at most a QVGA (Quarter Video Graphics Array) size (normally a vertical screen on a mobile phone, Number × vertical pixel number = 240 × 320 pixels).

  Due to the limitations on the screen, when an e-mail is received by a portable information communication device, if it is a long sentence, the text will not fit in the display screen and will be displayed over many lines. The vertical scrolling must be repeated many times, and as a result, the contents cannot be smoothly understood. On the other hand, the sender of an e-mail is a personal computer system of a desktop type or a notebook type (hereinafter referred to as a “desktop type or a notebook type personal computer system”) having a sufficiently large display screen. Therefore, even if there is no problem in displaying a long sentence on the screen, if such a restriction on the receiver side is taken into consideration, it is naturally intended for a portable information communication device. It must be a short email.

  Furthermore, restrictions when browsing a web page with a portable information communication device are greater than when reading e-mail. Usually, a web page (hereinafter abbreviated as a web page for a personal computer) created assuming browsing on a personal computer is a document file written in HTML (hereinafter abbreviated as an HTML file) and its link file. Consists of. However, many mobile phones cannot properly browse web pages written in full-spec HTML because one of the reasons is that the screen size and screen resolution of the attached display are small. It is a web page of a so-called “mobile phone site” constructed separately from a website for personal computers, and is a portable information communication device such as CHTML (Compact HTML), HDML (Handheld Device Markup Language) or WML (Wireless Markup Language) Only web pages written in a markup language specialized for. For this reason, a web page written in an HTML file linked to an image file with a particularly high resolution cannot be displayed correctly in most cases, and the screen is divided into a plurality of frames, and different URLs (Uniform Resource Locator) are used for each frame. In the first place, for example, a website including a frame-displayed web page to which a file having () is assigned, the administrator side may deny access from the mobile phone.

Recently, mobile phones having a “full browser function” or a “PC (Personal Computer) site view function” capable of browsing web pages for personal computers have been put on the market. Special rendering modes such as vertical QVGA, reduced to 240 pixels), line breaks of text in the screen width, and frame-based web pages are displayed in frame units. Therefore, it is not displayed in a layout realized as a screen image of a personal computer, which was originally intended by the creator of the web page.
In addition, some mobile phones may have a rendering mode that displays a layout similar to a screen image on a personal computer. Normally, a web page for a personal computer is at least a VGA (Video Graphics Array) size (number of horizontal pixels x vertical) In this rendering mode, the entire web page cannot be browsed unless horizontal scrolling is repeated many times. , You will have trouble understanding the full web page.

On the other hand, even when enjoying a game with a portable information communication device, the game is limited to a relatively simple game in which graphics can be displayed on a small attached display. For this reason, most of the so-called “mobile phone apps” games downloaded from the “mobile phone site” are games from one generation to several generations ago in the world of games for game consoles and PCs. In most cases, it is enjoyed for a short time.
In addition, when viewing a TV program on a mobile phone with a maximum screen resolution of the attached display of QVGA, it is set horizontally (horizontal pixel × vertical pixel = 320 × 240 pixels) in order to view it on the largest possible screen. Even in that case, the number of effective scanning lines (= vertical pixels. 480 in the case of analog TV broadcasting), which is assumed for TV broadcasting, is larger than the screen vertical resolution (240 pixels) of the attached display. Therefore, it is necessary to thin out the pixels for display. In particular, in digital television broadcasting, the number of effective horizontal pixels is defined in addition to the number of effective scanning lines (number of vertical pixels), but the number of horizontal pixels × vertical pixels = 720 even in the 480i system with the smallest resolution. In the case of a mobile phone with × 480 pixels, the so-called “full high-definition” 1080i method is 1920 × 1080 pixels and the screen resolution of the attached display is at most QVGA, sufficient TV tuner function and display An image having an original resolution (hereinafter abbreviated as an original image in a television broadcast) displayed when a television broadcast signal is appropriately processed by a television receiver having a function (hereinafter abbreviated as a television receiver). It cannot be displayed in full screen, and can only display images with lower resolution and inferior quality.

Under such circumstances, users of portable information communication devices often own personal computers together with portable information communication devices. In such cases, use your computer to send and receive long emails, browse web pages on your computer, or enjoy complex games that can only be displayed on large screens. The mobile information communication device is used in such a manner that the mobile information communication device is used only for sending and receiving a short mail or accessing a “site for mobile phone” to browse a web page. Alternatively, the personal computer and the portable information communication device are connected, the wireless communication means of the portable information communication device is used only for connection to the network, and the processing of the data acquired by the wireless communication means is performed exclusively by the personal computer. It is used like this.
Recently, a so-called “AV (Audio Visual) personal computer” having a built-in television tuner and a function for viewing a television program on a display has been sold. Such a personal computer and a television tuner are included. When a mobile phone is used in combination, a TV program is viewed on a mobile phone with a TV tuner when going out or moving, and is viewed on an “AV PC” at home or in the room.

However, a personal computer used in such a method is usually designed so that it can be used for general purposes that are not limited to e-mail transmission / reception and web page browsing performed by a portable information communication device. The portable information communication device itself has a processor such as a CPU (Central Processing Unit) that has higher functionality than the data processing means of the portable information communication device itself. In addition, in order to activate the hardware, software such as an OS (Operating System) must be prepared separately, so the cost required to own a personal computer is a portable information communication device such as a cellular phone. Usually more than the cost of owning it.
For this reason, for many users whose data communication and data processing needs are limited to sending and receiving e-mails and browsing web pages, they can read long e-mails and browse PC web pages as described above. It is economically unreasonable to own a separate personal computer just to eliminate the inconvenience caused by the small screen size and resolution of the attached display.
On the other hand, the data processing means of the portable information communication device is not necessarily suitable for general purposes, but the display data processing function for displaying an image on the attached display, except that the display screen is small. For example, it is comparable to the function of a processor such as a CPU in a personal computer. Nonetheless, if you use a personal computer and a portable information communication device as described above, you will make a double investment in the same type, resulting in a decrease in at least one of the operating rates. It is not preferable from the viewpoint of efficient use of resources.

  Similar problems of “irrational double investment” and “inefficient use of resources” also occur when the portable information communication device has a TV tuner function. In other words, in order to enjoy video and audio of a TV program, a TV tuner circuit for receiving a TV broadcast signal and displaying the TV program video on a display or TV monitor is required. On the other hand, a user of a normal portable information communication device has a small screen size of an attached display of the portable information communication device, and the displayed image quality is also inferior. It is normal to have “ For this reason, the user is forced to own both the TV tuner circuit in the portable information communication device and the TV tuner circuit in the TV receiver or the “AV personal computer”. As a result, the operation rate of at least one TV tuner circuit decreases. I have to.

  In digital terrestrial broadcasting, out of 13 segments that make up one channel, 12 segments (high-definition broadcasting) or 4 segments (normal-quality broadcasting) are allocated to broadcasting for ordinary TV receivers, while mobile information Only one segment will be allocated for communication devices. In this case, the TV tuner in the television receiver and the TV tuner in the portable information communication device have different specifications, so it is considered that no simple double investment will occur. . However, as a result of advances in electronics and information technology, there is a possibility that a TV tuner that can receive 12-segment or 4-segment broadcasting, which is assumed to be received by a normal television receiver, is placed inside the portable information communication device. In such a case, the same problem of “irrational double investment” and “inefficient use of resources” arises for an expensive digital TV tuner in the extension of the current technology.

  For this reason, long-sized e-mails, web pages for PCs, and entertainment are maintained without changing the size of the attached display as it is in order to maintain the portability of portable information communication devices. Display high-quality games, video of TV programs, etc. on a large screen. In particular, long e-mails can be read without repeated vertical scrolling. The problem is that a television program can be viewed without repeating horizontal scrolling, and that a television program can be displayed as a full screen image in a television broadcast.

In order to solve such problems, an external display device having a larger screen than the display attached to the portable information communication device (hereinafter abbreviated as a large screen external display device) is connected to the portable information communication device. Several techniques for displaying images on an external screen display device have been disclosed, and these techniques are classified into the following three types.
First type: A type in which a portable information communication device and a large-screen external display device are connected via some connection unit. Second type: A portable information communication device and a large-screen external display device are directly connected. As a large screen external display device, an image display device having a function of performing various processes on display data received from the portable information communication device is used. Third type: The portable information communication device and the large screen external display device are directly used. In addition, the large screen external display device is a type in which a general-purpose display such as a TV monitor is used, except that it has some interface means with the portable information communication device.

Among these, the 1st type technique is disclosed in patent document 1, patent document 2, patent document 3, and patent document 4, for example.
In the technologies disclosed in these patent documents, it is not necessary to use a personal computer separately from the portable information communication device, but instead, a processor (in the case of Patent Document 1) and a CPU (in the case of Patent Document 2) are separately provided. A connection unit including some display data processing means such as a read control circuit (in the case of Patent Document 3) and a display control means (in the case of Patent Document 4) is required. These display data processing means have a function only for displaying characters and images on the screen of a large-screen external display device, and are used for general purposes such as a processor such as a CPU in a personal computer and software such as an OS. It is not used for For this reason, the price of any connection unit provided with these display data processing means is lower than that of a personal computer, and there is a possibility that the economic burden for owning it will be smaller than when using a personal computer together.

  However, even in this case, considering only the display data processing function for displaying images and characters, it is almost the same except that the screen size to be displayed is different on the portable information communication device side and the connection unit side. The display data processing means having the function is held twice. For this reason, the problems of “irrational double investment” and “inefficient use of resources”, which are more or less the same as when using a personal computer together, will arise. In reality, the purchase cost of the connection unit may be the same as or higher than that of a personal computer if the number of connection units sold is significantly less than the number of personal computer sales.

On the other hand, the second type technique is disclosed in, for example, Patent Document 5, Patent Document 6, Patent Document 7, Patent Document 8, and Patent Document 9.
This type of technology does not require a personal computer or a connection unit equivalent to it, but this time, a general-purpose display device such as a television receiver cannot be used as it is as a large screen external display device. System (microcomputer) (in the case of Patent Document 5), control unit 15 (in the case of Patent Document 6; separate from the control unit 10 on the wireless telephone side), high-definition conversion unit and display processing unit (in the case of Patent Document 7) An image display device provided with display data processing means such as an enlargement circuit, a display circuit (in Patent Document 8), or a CPU (in Patent Document 9) must be used.
In Patent Document 6, a third type technique is also disclosed. In this case, the control unit 10 on the wireless telephone side has an additional display data processing function, and a large screen external display device is provided. The control unit 15 on the (portable display) side only sends display data input from the connector terminal 13 to the liquid crystal display of the portable display, and does not have a display data processing function. This will be explained again in the section describing the third type of technology.

  As described above, even in the second type of technology, the portable information communication device side and the large screen external display device side have double display data processing means having substantially the same function, and as a result Problems of “irrational double investment” and “inefficient use of resources” arise. In addition, the purchase cost of an image display device provided with such display data processing means is certainly higher than that of a general-purpose CRT (Cathode Ray Tube) display device or liquid crystal display device. In this case, an unreasonable economic burden that should be avoided is generated, as is the case with the combined use with a personal computer and the first type technology.

  On the other hand, the third type technology does not use a connection unit or a special image processing device, and is composed only of a portable information communication device and a general-purpose large-screen external display device. For this reason, it is generally considered that the problems of “irrational double investment” and “inefficient use of resources” are less than at least the first type technology and the second type technology.

  As this third type of technology, there is a mobile phone having a so-called “TV (TV) output function” or “AV output function”. In such a mobile phone, the digital phone attached to the mobile phone is connected by connecting the mobile phone and the TV monitor with a cable that has a connection terminal specific to the mobile phone on the mobile phone side and a video terminal on the TV monitor side. Still images, moving images, or some games shot using the camera function can be displayed on a television monitor having a larger screen than the display attached to the mobile phone. However, in this case, the resolution of the image displayed on the TV monitor is the same as the screen resolution of the attached display (QVGA at the maximum). Either a coarse enlarged image is displayed on the full screen.

  At present, what is displayed on the TV monitor by the “TV output function” or “AV output function” is limited to the photographed still image, moving image, or some games. Has a “full browser function” or “PC site view function”, and even if the web page for a PC that has been viewed can be viewed on a TV monitor, it will only enlarge the screen image displayed on the attached display. It does not increase the resolution of the screen image. Therefore, the display with the layout realized as the screen image of the personal computer that the creator of the web page originally intended cannot be realized on the television monitor. Further, even if these mobile phones have a TV tuner function and can output received video to a TV monitor, the original image in TV broadcasting is not displayed on the TV monitor.

Therefore, in order to solve the above problem, an image displayed on the attached display is simply enlarged and displayed on the large-screen external display device like a mobile phone having a “TV output function” or an “AV output function”. It is necessary to provide a portable information communication device having a function of displaying an image having a resolution larger than that of the attached display on the large-screen external display device.
As a result, the attached display can only display partial images that are cut out only for the part corresponding to its own screen resolution, or can display only the entire image with reduced image quality by thinning out pixels. Can be displayed as an entire image at its original resolution. In particular, in the case of having a function for displaying an image larger than the horizontal resolution of the attached display on the large screen external display device in the horizontal direction, the number of characters that can be displayed per line can be increased. Even long e-mails are displayed over many lines, eliminating the need for repeated vertical scrolling. Further, by combining these effects, a web page for a personal computer can be browsed in a layout realized as a screen image of the personal computer on a large screen external display device.

  Now, a third type of technology aiming to solve a problem similar to the above problem is disclosed in, for example, Patent Document 6, Patent Document 10, Patent Document 11, Patent Document 12, and Patent Document 13. .

Of these, first, in Patent Document 10 and Patent Document 11, a television receiver including a digital television is selected as a large screen external display device, and then a video circuit and a video are used as interface means with the large screen external display device. It is disclosed that a terminal, an interface circuit and a connector, a transmitter circuit and an antenna (in the case of Patent Document 10), or a proximity communication means (unit) (in the case of Patent Document 11) are provided. However, these documents do not describe any mechanism for displaying screen images having different amounts of information on a display (display unit) of a mobile phone having a different screen size and a large screen external display device. .
In fact, Patent Document 11 discloses that the control unit 17 controls both the display unit 11 and the proximity communication unit 18, but a screen image with a small amount of information is displayed on the display unit 11 with the proximity communication unit 18. Since a screen image with a large amount of information is respectively displayed on the digital television 2 that transmits and receives data between them, there is no disclosure about what function the control unit 17 has. On the other hand, Patent Document 10 suggests that the display operation unit controls the signal output to the (digital) television receiver, but in the first place, what is the display of the screen image on the display on the mobile phone side? There is no disclosure of how this is done.

  On the other hand, in Patent Document 6 and Patent Document 12, a portable display (in the case of Patent Document 6) or a CRT display (in the case of Patent Document 12) is selected as a large-screen external display device, and an external interface is used as an interface unit. It is disclosed that an interface (in the case of Patent Document 6) or a monitor terminal (in the case of Patent Document 12) is provided, and a display unit of a wireless telephone (in the case of Patent Document 6) or a simplified liquid crystal display panel of a mobile phone (patent) Document 12) discloses a mechanism for displaying a screen image with a small amount of information and a screen image with a large amount of information on a large-screen external display device.

Firstly, in Patent Document 6, the control unit 10 on the wireless telephone side has a function of outputting image display data to the external interface 3 in addition to the display unit 2 of the wireless telephone, as well as an enlarged display processing means and an enlarged display process. It is disclosed that a function as a control means and / or a function as a line feed processing means or a line feed processing control means is added, so that in the liquid crystal display 12 on the portable display side, It is described that an image of a larger size can be displayed on the display unit 2 and the number of characters per line can be increased.
However, the additional functions disclosed therein are limited to an enlarged display function and a function related to character display as realized by a mobile phone having the “TV output function” or “AV output function”. ing. For this reason, with the technology disclosed in Patent Document 6 alone, for example, an image that can only display a partial image or an entire image with reduced image quality on the display attached to the portable information communication device is displayed on the large screen external display device. It cannot be displayed as an entire image in its original resolution. Therefore, the technique disclosed in Patent Document 6 completely solves the problem of providing a portable information communication device having a function of displaying an image having a resolution larger than the screen resolution of the attached display on a large-screen external display device. Not a thing.

  On the other hand, in Patent Document 12, the display control circuit 21 distributes the input display data to the monitor terminal 25 connected to the portable liquid crystal display panel 23 and the CRT display 24 under the control of the CPU 11. Therefore, when there is a lot of display data on the screen for forming an image and the content of the display data does not correspond to the simplified liquid crystal display panel 23, the CRT display 24 is used. It is said that all necessary display data can be displayed without omission by using it.

At first glance, it seems that this technique can solve the above-described problem of displaying an image having a resolution larger than the screen resolution of the attached display in the large-screen external display device. However, Patent Document 12 has the following two problems.
First, the distribution mechanism when the display control circuit 21 distributes display data to the simplified liquid crystal display panel 23 and the monitor terminal 25 and sends it is unknown. Japanese Patent Application Laid-Open No. 2003-228561 has a description “when the content of the display data corresponds to...” Or “when the display data transmission destination indicates... It is not disclosed at all what mechanism is determined and what mechanism the “instruction” is realized.
Second, display data “corresponding to the CRT display 24” is input to the display control circuit 21 when the mobile phone is used alone without the CRT display 24 connected to the monitor terminal 25. In this case, it is unclear what kind of image is displayed on the simplified liquid crystal display panel 23. In such a case, if no image is displayed on the simplified liquid crystal display panel 23, the convenience of the user is impaired. Conversely, for example, a partial image is displayed on the simplified liquid crystal display panel 23. If the entire image can be viewed by scroll operation, no mechanism for realizing it is disclosed.
Therefore, the technique disclosed in Patent Document 12 also does not solve the problem of providing a portable information communication device having a function of displaying an image having a resolution larger than the screen resolution of the attached display on a large-screen external display device. Absent.

Now, finally, the patent document 13 comprises a web page for personal computers by providing a processor having various functions inside the telephone in order to display it on the screen of a television receiver which is a large screen external display device. Technology for displaying various types of information including HTML content to be displayed on a large screen of a television receiver. According to this, in a large-screen external display device, the resolution is higher than the screen resolution of an attached display. It is assumed that it is possible to display an image with a large.
However, the processor 50 provided inside the telephone here is a high-grade one including various processors such as a CPU 50a, a graphic processor, a sound processor, a DMA processor, and an input / output port. In addition, when a video signal is output to the large-screen external display, the processor 50 is solely responsible for image processing. At that time, the CPU 36 on the telephone side performs key input information and HTML based on a request from the CPU 50a in the processor 50. It is only responsible for the delivery of content data. As far as image processing is concerned, a mobile phone is used in combination with a personal computer, and the mobile phone is similar to the case where the wireless communication means of the portable information communication device is used only for connection to the network. It becomes the use situation.
Therefore, although the technology disclosed in Patent Document 13 is classified into the third type of technology, the problems of “irrational double investment” and “inefficient use of resources” Or it is not much different from the second type of technology.

The
For example, a mobile phone capable of transmitting a high-resolution external display signal in which the screen resolution of the attached display panel is QVGA size and the original resolution is XGA size (horizontal pixel number: vertical pixel number = 4: 3) is realized. In the information communication apparatus, the interface means A1 of the portable information communication apparatus has a multi-scan function and the screen resolution is, for example, SXGA (Super XGA) size (the number of horizontal pixels × the number of vertical pixels = 1280 × 1024 pixels). By connecting a peripheral device including a high-performance external display means and / or a peripheral device to which the external display means is connected, an XGA size image having a resolution higher than the screen resolution (QVGA size) of the attached display panel can be obtained. Display over the entire screen of the high performance external display means (without creating a non-display area) can do.

  A similar effect is obtained by connecting the interface unit A1 of the portable information communication device and the high-resolution external display unit with a function of up-scan converting the original resolution of the high-resolution external display signal to the screen resolution of the high-resolution external display unit. It can also be realized by connecting through the network. For example, the function of transmitting a high-resolution external display signal in which the screen resolution of the display panel attached to the portable information communication apparatus is QVGA size and the original resolution is XGA size is realized. When a full high-definition television monitor (the number of horizontal pixels × the number of vertical pixels = 1920 × 1080 pixels) is used, a connection unit having the necessary up-scan function is provided between the full high-definition television monitor and the interface means A1 of the portable information communication device. Can be used to display an XGA size image with a resolution larger than the screen resolution (QVGA size) of the attached display panel over the entire screen of the full high-definition television monitor (however, the XGA size and Full high definition size Flat since the vertical ratios are different, in some cases non-display area at both ends occurs).

On the other hand, in particular, according to the fourth aspect of the present invention, it is possible to cope with a fixed resolution determined in advance from among a display device for a personal computer and a television monitor which are used for general purposes without using a display device having a multi-scan function. By selecting one having the screen resolution and using it as the high-resolution external display means, it is possible to display a high-resolution image over the entire screen of the high-resolution external display means. In particular, according to the fifth aspect of the present invention, a high-resolution external display signal is obtained by using an appropriate one from a general-purpose personal computer display device or a television monitor as the high-resolution external display means, and the resolution specifying means. By selecting and specifying the screen resolution of the high-resolution external display means as the original resolution, a high-resolution image can be displayed over the entire screen of the high-resolution external display means. Further, in particular, according to the sixth invention, it is not necessary to designate the original resolution of the high resolution external display signal by manual operation, and a resolution suitable for the screen resolution of the high resolution external display means in the peripheral device is automatically selected. The
Note that if the high-performance external display means having a multi-scan function is used as the high-resolution external display means, the designated resolution will not be the same as the screen resolution of the high-performance external display. If it is smaller than the screen resolution of the high performance external display, an image having a designated resolution can be displayed over the entire screen of the high performance external display means.

  Of these, particularly according to the sixteenth or seventeenth invention, a display device having general-purpose interface means can be adopted as the high-resolution external display means. In particular, in the sixteenth aspect, when a digital display device such as a liquid crystal display device is used as the high-resolution external display means, signal conversion of “digital (bitmap data) → analog → digital” becomes unnecessary. It is possible to avoid image degradation accompanying conversion. On the other hand, in the seventeenth invention, a general-purpose personal computer display device having an analog RGB interface such as a TV monitor or a VGA connector can be used as the high-resolution external display means.

  In the portable information communication device of the eighteenth invention, when displaying a high resolution image on the screen of the high resolution external display means in the peripheral device connected to the interface means A1 of the portable information communication device, the high resolution external display means, Power is supplied via a charging terminal A from a connection unit that mediates the interface unit A1 and the high-resolution external display unit, or an external input / output unit in which the connection unit and the external display device are integrated. Thus, the built-in rechargeable battery of the portable information communication device can be charged.

  In the portable information communication device according to any one of the nineteenth to twenty-first aspects, a high-resolution image can be displayed on the screen of the high-resolution external display means in the peripheral device connected to the interface means A1 of the portable information communication device. In addition, the interface means A2 of the portable information communication device includes a full-size keyboard such as a JIS layout Japanese 106 keyboard or a Japanese 109 keyboard used in a personal computer (hereinafter referred to as “JIS layout Japanese 106 keyboard”). Or, a full keyboard such as a Japanese 109 keyboard is abbreviated as “full keyboard”), so that data can be input with the full keyboard.

In the first place, in mobile information communication devices such as mobile phones, editing e-mails, inputting URLs of websites, inputting characters into forms on web pages, and editing partner data in the phone book function of mobile phones For example, character input operations using attached operation keys are increasing. Nevertheless, in the portable information communication device, since portability is important, the attached operation keys are smaller than the operation keys in the full keyboard, and the distance between the centers of adjacent operation keys is also small. There was a problem that the operability of character input was bad. In particular, in the case of a mobile phone, the operation keys are limited to a small number of keys with several function keys added to the numeric keypad. For example, when inputting “o”, the function keys may be used. After switching to the input mode, you need to press the number key (usually the “1” key) assigned to line a five times, as in editing a long e-mail. When a large number of characters had to be input, a great burden was involved.
On the other hand, the portable information communication device according to any one of the nineteenth to twenty-first aspects relaxes the restriction on data (character) input in addition to the restriction on the screen because portability is important.・ It will be solved. Actually, in addition to the portable information communication device of any one of the nineteenth to twenty-first inventions, an external display device such as a general-purpose personal computer display device or an external input device such as a full keyboard is prepared, and the interface means A1 and As long as it is connected to A2 directly or via a connection unit, as long as it is related to work such as editing / transmission / reception of e-mails, browsing of web pages, interactive communication, etc. It will be possible to achieve almost the same operability.

  On the other hand, from the viewpoint of continuity and connectivity of work between going out and staying at home or office, the portable information communication device according to any one of the nineteenth to twenty-first inventions is provided with an external display device. In some cases, it is more convenient to use a conventional portable information communication device in combination with a personal computer.

A user who has a personal computer together with a conventional portable information communication device usually needs to have two mail addresses: a mail address in the portable information communication device and a mail address in the personal computer. Both sides must check the status of mail reception. Depending on the provider, there is a case where a service is provided so that both a mobile phone and a personal computer can receive an email sent to a single email address. Since the mailer and the mailer in the personal computer are separate, there is a disadvantage that mail received by the personal computer does not remain in the reception history in the portable information communication device or vice versa. In addition, there is a trouble of separately editing the mail address list in the portable information communication device and the mail address list in the personal computer.
Furthermore, for example, when returning to an environment where a personal computer can be used while browsing a web page using a portable information communication device when going out, when trying to view the same web page on a large screen on the personal computer, Although the portable information communication apparatus is already connected to the website, it takes time to input the URL of the website again after starting the personal computer. In addition, when you return to an environment where you can use the computer while you are entering the mail text by operating the operation keys on the portable information communication device when you are away from home, you can use the full keyboard on the PC to write the mail text. When the mobile information communication device has already input halfway through the sentence, it is necessary to input again from the beginning of the sentence after starting up the personal computer. As described above, it is impossible to smoothly move from the work in the portable information communication device to the work in the personal computer, and normally, when the personal computer is started, it takes longer time than the start of the mobile phone. There is also.

  On the other hand, when an external display device and an external input device are connected to the portable information communication device of any one of the nineteenth to twenty-first inventions, data processing is consistently performed in the portable information communication device. The data processing means performs necessary data such as an e-mail address, and is also stored in a storage means such as a flash memory in the portable information communication device. For this reason, even when returning from the outside to the home or office, it is possible to continue the work smoothly only by connecting the portable information communication device, the external display device and the external input device, and the portable information communication device. There is no need to manage data in a double manner, as in the case of using a computer with a computer.

Furthermore, by connecting and using the external display device and the external input device to the portable information communication device according to any one of the nineteenth to twenty-first aspects, an effect of suppressing waste of resources can be expected.
It is said that personal computers are upgraded at a very fast speed mainly in response to version upgrades of the OS and CPU, and as a result, replacement is carried out in an average of 3 to 7 years. At that time, with the exception of some skilled personnel, not only the main body centered on the motherboard with the CPU and memory mounted, but also external storage devices such as display devices, full keyboards, and HDDs (Hard Disk Drives) are discarded at the same time. It is normal.
On the other hand, when an external display device and an external input device are connected to the portable information communication device of any one of the nineteenth to twenty-first inventions, the portable information communication device is used independently. Therefore, even if the data processing means such as the central processing circuit in the portable information communication device becomes highly functional and the previous one becomes obsolete, it is only necessary to replace the portable information communication device, and the others are left as they are. Can be used. As a result, mass disposal associated with replacement by purchase does not occur like a personal computer.

  In the portable information communication device of the twenty-second and twenty-third inventions, by connecting an external storage device to the interface means A3 of the portable information communication device, the data processing means of the portable information communication device sends data to the external storage device. It becomes possible to write and read. For this reason, images downloaded from websites, videos recorded from TV broadcasts, content such as game programs, and image files generated using imaging means such as digital cameras and digital videos are attached with limited data capacity. It can be stored not in the storage means but in an external storage device. Further, by using an external storage device for application providing media such as a CD-ROM (Compact Disc Read Only Memory) drive and a DVD (Digital Versatile Disc or Digital Video Disc) -ROM drive as an external storage device, a CD-ROM Or an application program stored in a DVD-ROM can be ported to an auxiliary storage means such as a flash memory, and the data processing means can be driven by the program.

Even in a conventional mobile phone, if a removable storage medium such as a memory card is used, a content file such as an image file acquired by a communication means or an imaging means can be ported to a storage device such as a personal computer. . However, in that case, the content file stored in the storage means of the mobile phone is copied to the removable media, the removable media is removed from the mobile phone, and inserted into a media drive such as a personal computer. A procedure is required in which the data processing means or the like is driven to transfer the removable media to the HDD.
On the other hand, in the portable information communication devices of the twenty-second and twenty-third inventions, the data processing means in the portable information communication device can directly access the external storage device when the external storage device is connected to the interface means A3. Therefore, the file can be directly transplanted from the storage means of the portable information communication device to the external storage device without using a removable medium.

  In the portable information communication device according to any one of the twenty-fourth to the twenty-sixth inventions, the portable information communication device, in addition to browsing the attached display panel as usual in a web server on a web server connected to the Internet, It can be viewed on the screen of the high-resolution external display means in the peripheral device connected to the interface means A1 of the communication device. In addition, the portable information communication device obtains an image file, a content file such as a game program from a web server, and displays an image corresponding to the web page or content file on the attached display panel as usual. In addition, it can be displayed on the screen of a high resolution external display means. In addition, at that time, a high-resolution image having a resolution larger than the screen resolution of the attached display panel can be displayed without being restricted by the screen resolution of the attached display panel.

In particular, according to the twenty-fifth or twenty-sixth aspect of the present invention, the mobile information communication device is a high-level device that the portable information communication device possesses by interlocking with the CGI (Common Gateway Interface) or PHP (Hypertext Preprocessor) function on the web server side. It is possible to receive a service that can fully utilize the transmission function of the resolution external display signal.
For example, a web server has three types of websites that provide a download service for image data files of moving images and still images, one of which can download only image data files originally having a resolution of QVGA, The other one can download only the image data file whose resolution is originally XGA size, and the other one is that the image data file whose resolution is originally QVGA size and XGA size can be downloaded by one operation. When the web server receives user agent information including information indicating that it has a function of transmitting a high resolution external display signal from a portable information communication device that is accessing the web server, the original resolution is QVGA size and XGA. Download both size image data files at once If the mobile information communication device of the 25th or 26th invention is automatically distributed so as to access the website, the image data file displayed on the attached display panel without the user's conscious operation each time. And the image data file to be displayed on the screen of the high resolution external display means can be downloaded at a time.

  In particular, according to the twenty-sixth invention, for example, the web server has two types of websites including a web page composed of a markup document file and a link file, one of which is a VGA. If the web server includes a fixed-width layout web page of size or XGA size, and the other is composed of only a liquid layout or a fixed-width layout web page with a small number of horizontal pixels, the web server accesses itself. When receiving user agent information including information indicating that the transmission destination designation means designates the interface means A1 as the transmission destination of the digital display signal from the portable information communication device that is present, the VGA size or the XGA size A website that contains a web page with a fixed-width layout If it is not, the mobile information can be automatically distributed so that the website is configured to access only the web page having only the liquid layout or the fixed-width layout with a small number of horizontal pixels. In a system comprising a communication device and an external display device, a page image suitable for the currently active display means can be automatically displayed.

In the portable information communication device according to the twenty-seventh aspect of the invention, in addition to displaying the moving image transmitted by the wireless moving image signal in real time on the attached display panel, it is possible to increase the height of the peripheral device connected to the interface means A1 of the portable information communication device. Real-time display is also possible on the screen of the resolution external display means. In addition, at that time, a moving image having a resolution larger than the screen resolution of the attached display panel can be displayed without being restricted by the screen resolution of the attached display panel.
In addition, the moving image transmitted by the wireless moving image signal can be recorded and converted into a moving image data file, stored in the attached storage means, and read out and reproduced later. In this case, the moving image can be displayed not only on the attached display but also on a high-resolution external display.

In the portable information communication device of the twenty-eighth aspect of the invention, in addition to imaging a subject using the portable information communication device and displaying a moving image of the subject in real time on the attached display panel, interface means of the portable information communication device It can also be displayed in real time on the screen of the high resolution external display means in the peripheral device connected to A1. In addition, at that time, a high-resolution image having a resolution larger than the screen resolution of the attached display panel can be displayed without being restricted by the screen resolution of the attached display panel.
In addition, the captured still image or moving image can be converted into a data file, stored in the attached storage means, and read out and reproduced later. In this case, the moving image can be displayed not only on the attached display but also on a high-resolution external display.

In the portable information communication device according to any one of the twenty-ninth to thirty-second inventions, a markup document file and its link file acquired from a web server, or a markup document file and its link file stored in storage means are processed. In addition to the attached display panel, page images corresponding to these files can be displayed on the screen of the high-resolution external display means in the peripheral device connected to the interface means A1 of the portable information communication device.
In particular, for example, a mobile information communication device with an attached display panel having a screen resolution of QVGA size is connected to a website for a personal computer, and a web page created assuming that the screen is viewed on a VGA size screen, for example, is viewed. In the case, as in the prior art, not only is it possible to browse the entire display by repeatedly scrolling horizontally on the attached display panel, but also on the screen of the high resolution external display means in the peripheral device connected to the interface means A1 of the portable information communication device. , It will be displayed in a layout similar to a screen image on a personal computer, and can be viewed without horizontal scrolling.

  In the portable information communication device according to any one of the thirty-third to thirty-seventh inventions, a high resolution external display in a peripheral device connected to the interface means A1 of the portable information communication device is used to display the original image of the digital moving image signal or image data file. It can be displayed on the screen of the means. In particular, when the resolution of the original image is larger than the screen resolution of the attached display panel of the portable information communication device, the attached display panel generates an entire image or portion having a low resolution generated by thinning out a part of the signal or data. Whereas an image is displayed, on the screen of the high-resolution external display means, an original image or an image with high resolution can be displayed by interpolating pixels in the original image.

In particular, in the portable information communication device according to the thirty-seventh aspect of the present invention, by combining a digital signal obtained by converting a GPS signal and map information, a map image including its current position information is added to the attached display panel and the portable information communication device. It can also be displayed on the screen of the high-resolution external display means in the peripheral device connected to the device interface means A1.
As a service for mobile phones, there is a navigation service using GPS. Recently, in addition to normal navigation information, traffic information is provided or route information to a destination is provided, so-called “passenger seat navigation”. "Services are also being offered. However, since the screen of the display attached to the mobile phone is small in the first place and it is necessary to hold the mobile phone in front when browsing the map information displayed there, it is legal for the driver to browse it. Neither can be practical. For this reason, it is assumed that this service is operated and viewed by the passenger as the name indicates.
On the other hand, in the portable information communication device of the thirty-seventh aspect of the invention, a peripheral device and / or a high-resolution external display including high-resolution external display means having the same size as the display panel portion of a normal car navigation system The peripheral device to which the means is connected is connected to the interface unit A1 of the portable information communication device, and is fixed at the same position as the display panel unit of a normal car navigation system, so that the driver himself can obtain map information in a hands-free manner. It becomes possible to browse.

  In the connection unit for a portable information communication device according to any one of the thirty-eighth to the forty-second inventions, the portable information communication device and the high resolution external display are connected by connecting the portable information communication device and the high resolution external display through the connection unit. The following merits are obtained as compared with the case where the apparatus is directly connected.

First, in the portable information communication device, since portability is regarded as important, the terminal portion constituting the interface means A1 must also be a small special one that is different from those used for general purposes in personal computers and the like. I do not get. For this reason, since the connection cable connected to the terminal portion is also special, it is difficult to prepare cables of various lengths. Therefore, the connection cable between the portable information communication device and the high-resolution external display device is difficult. If the direct connection is made, the positional relationship is naturally limited.
On the other hand, if the connection unit for portable information communication device according to any one of the thirty-eighth to the forty-second inventions is mediated, the interface means A1 of the portable information communication device and the interface means B1 of the connection unit are connected by a special cable. On the other hand, the terminal of the interface unit B2 of the connection unit is a general-purpose terminal suitable for a high-resolution external display device, and the interface unit B2 and the high-resolution external display unit are connected by a general-purpose cable. And high-resolution displays can be arranged relatively freely. As a result, the portable information communication device and the high-resolution external display means can be arranged in a free positional relationship.

  The portable information communication device and the high-resolution external display means can be connected not only by a connection cable but also by using a wireless means. Even in such a case, any one of the 38th to 42nd If the connection unit for portable information communication device of the invention is used, the connection between the interface means A1 and the interface means B1 is connected by wired means, and the interface means B2 and the high resolution external display are connected by wireless means (or vice versa). In other words, it is possible to achieve more reliable data exchange by avoiding problems of wireless reach and obstacles.

Next, when connecting an external input device such as a full keyboard and / or an external storage device such as an HDD in addition to a high-resolution external display device to the portable information communication device, an attempt is made to directly connect them with a connection cable Then, since a plurality of connection cables are required, there is a problem in the device structure that a plurality of connection terminals must be provided in a portable information communication device in which downsizing is an essential requirement because portability is important.
On the other hand, when the connection unit for portable information communication device according to any one of the thirty-eighth to forty-second inventions is mediated, the terminal unit constituting the interface means A1 on the portable information communication device side and the interface means A2 are provided. The terminal part constituting and / or the terminal part constituting the interface means A3 are integrated, while the terminal part constituting the interface means B1 on the connection unit side and the terminal part and / or interface means B3 constituting the interface means B2 are integrated. It is possible to connect the integrated terminal portions to each other.
In addition, an external storage device such as an HDD or DC power supply means composed of an AC / DC circuit or a rechargeable battery is placed inside the housing constituting the connection unit, and a portable information communication device is inserted into the housing. By providing an insertion port so that the terminal portion of the portable information communication device and the terminal portion of the connection unit are in direct contact with each other to facilitate the connection between the portable information communication device and the connection unit, The connection unit to which the portable information communication device is connected can be used as if it were a desktop type personal computer.
In this case, the connection unit needs to be provided with a plurality of connection terminals in order to connect to the peripheral device. However, since the connection unit is not carried and used, the mobile information communication device is provided with a plurality of connection terminals. Such a problem does not occur.

  Note that the connection unit for portable information communication device according to any one of the thirty-eighth to forty-second inventions exclusively has an interface function between the portable information communication device and the peripheral device, and will be described in [Background Art]. Unlike the connection unit in the first type of technology, it does not include dedicated display data generation means for generating display data separately from the data processing means on the portable information communication apparatus side. For this reason, the problems of “irrational double investment” and “inefficient use of resources” as in the conventional technology do not occur.

  In the external input / output unit for a portable information communication device according to any one of the 43rd to 49th inventions, the portable information communication device is used as a high-resolution external display device by connecting it to the portable information communication device. The following merits are obtained as compared with the case where the portable information communication device and the high-resolution external display means are connected via a connection unit.

First, since the interface means with the portable information communication device, the external display means, the external input means such as the keyboard, and the external storage means such as the HDD are integrated, the connection between the portable information device and the peripheral device is simplified. Is done. In particular, the terminal part constituting the interface means A1 on the portable information communication device side and the terminal part constituting the interface means A2 and / or the terminal part constituting the interface means A3 are integrated, while the terminal part constituting the interface means A3 is integrated. By integrating the terminal part constituting the interface means D1, the terminal part constituting the interface means D2 and / or the terminal part constituting the interface means D3, and connecting the integrated terminal parts, portable information The connection between the communication device and the external display means and the external input means can be simplified.
In that case, an external storage device such as an HDD or a rechargeable battery is housed in a housing constituting the external input / output unit, and an AC / DC circuit or a commercial power plug is connected to the rechargeable battery, thereby The external input / output unit to which the information communication device is connected can be used as if it were using a notebook type personal computer.

  Since the portable information communication device and the external input / output unit are connected with a special cable for the same reason as described in the description of the connection unit for the portable information communication device, the positional relationship between the two In the first place, the external I / O unit is supposed to be used close to a notebook-type personal computer. Therefore, the portable information communication device and the connection unit are relatively close to each other, so there is a particular problem. Absent.

  Of these, particularly according to the 46th and 49th inventions, the external input / output unit is compact because the external display panel attached to the external input / output unit and / or the frame portion of the external display panel is provided with an external input function. It can be set as a simple structure. Therefore, it is suitable for the case where the portable information communication device according to any one of the seventeenth to twenty-first inventions and the 43rd and 46th external input / output units are combined to function as a car navigation system.

  When the portable information communication device of any one of the nineteenth to twenty-third inventions and the 46th and 49th external input / output units are connected to function as an in-vehicle call system, the portable information communication device is a voice call. On the other hand, an external input / output unit is attached with an external speaker and an external microphone, and a function for exchanging audio data converted into a digital signal is given to the interface between the two. As a result, a hands-free in-vehicle call system can be constructed.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. However, the present invention is not limited to such an embodiment, and various modifications can be made within the scope of the technical idea.

(First embodiment)
FIG. 1 shows a portable information communication device, a portable information communication device connection unit according to a first embodiment of the present invention, and by connecting an external display device and an external input device to the connection unit after connecting them. It is a block diagram for demonstrating the structure and function of the comprised information communication system, and demonstrates the case where this portable information communication apparatus is a mobile telephone especially.

In this embodiment, the mobile phone 1 alone is used for voice calls, for communication with a mobile videophone, for data communication / processing, for viewing a TV broadcast program, for shooting a subject, or for image data and It can be used for storing / reproducing voice data, and when used for purposes other than voice calls, various images are displayed on an LCD (Liquid Crystal Display) panel 15A, which is an attached display panel. .
In the following description, the LCD panel 15A is described as having a QVGA size screen resolution and normally used in a portrait screen (horizontal pixel × vertical pixel = 240 × 320 pixels). Also good.

First, when the mobile phone 1 is used for a voice call, the voice input from the microphone 18A is converted into a digital signal by a CODEC (COder-DECoder) 18C, and the digital signal is converted into a baseband processor 11 and an RF (Radio Frequency). ) The signal is transmitted as a radio signal from the communication antenna 111A to the public network via the transmission / reception unit 111B. Conversely, voice data transmitted to the public network as a radio signal from the other party of the voice call is received by the communication antenna 111A, converted into a digital signal through the RF transceiver 111B and the baseband processor 11, The digital signal is converted into an analog electric signal by the CODEC 18C, and finally outputted as sound from the speaker 18B.
Note that radio signal transmission / reception with a public network is performed by communicating with a base station of a mobile communication cellular network by a method such as CDMA (Code Division Multiple Access), or a wireless LAN base station. It is executed by communicating with an access point by a method such as DSSS (Direct Sequence Spread Spectrum) or OFDM (Orthogonal Frequency Division Multiplexing).

Next, when the mobile phone 1 is used for communication in a mobile videophone, in addition to the exchange of audio data described above, the following exchange of image (moving image) data is added.
That is, an optical signal reflected or radiated from a subject that is normally a user of the mobile phone 1 is incident on the CCD 12B via an optical system unit 12A composed of an optical lens or the like, and an electrical signal for each pixel in the CCD 12B. Is converted into a digital moving image signal by the AD / DA conversion unit 2_12C and transmitted to the central processing circuit 1_10A1 via the bus 19. The digital moving image signal is subjected to necessary processing in the central processing circuit 1_10A1, and is transmitted to the public network as a radio wave signal from the communication antenna 111A via the baseband processor 11 and the RF transmission / reception unit 111B in the same manner as the audio data. The
In the following description, it is assumed that the resolution of the CCD 12B is SXGA size (the number of horizontal pixels × the number of vertical pixels = 1280 × 1024 pixels), but other resolutions may be used.

On the other hand, image (moving image) data transmitted to the public network as a radio wave signal (wireless moving image signal) from a communication partner is received by the communication antenna 111A and digitally transmitted via the RF transmitting / receiving unit 111B and the baseband processor 11. After being converted into a signal, it is transmitted to the central processing circuit 1_10A1. The central processing circuit 1_10A1 performs necessary processing based on the program stored in the flash memory 14A, and transmits a drawing command corresponding to the digital signal to the graphic controller 1_10B.
Based on the rendering command, the graphic controller 1_10B has a logical resolution of a sufficiently large size (hereinafter, described as a QUXGA Wide (Quad Ultra XGA Wide) size (the number of horizontal pixels × the number of vertical pixels = 3840 × 2400 pixels)). Bitmap data in a virtual screen set to have is generated, and the bitmap data is transmitted to the LCD driver 15B while writing / reading to / from a VRAM (Video RAM) 1_10C as necessary. The VRAM 1_10C corresponds to the bitmap memory 1 in the “claims”.
The LCD driver 15B drives each pixel constituting the screen of the LCD panel 15A by operating the source driver unit and the gate driver unit based on the bitmap data, and finally from the communication partner An image corresponding to the wireless moving image signal is displayed on the LCD panel 15A.
At this time, since the resolution of the original image of the wireless video signal transmitted / received in the mobile videophone does not normally exceed the screen resolution of the LCD panel 15A, the LCD panel 15A displays the original image in full screen, The original image is displayed on a part of the screen of the LCD panel 15A, or the original image is enlarged and displayed on the entire screen without changing the resolution of the original image.
Note that transmission / reception of radio signals (audio signals and video signals) in mobile videophones can be realized by various communication methods as in the case of voice communication, but in particular, when a CDMA method is adopted in a cellular network, 3G-324M can be adopted as a communication standard.

Next, when the cellular phone 1 is used for data communication and processing, it is usually input by operating the key operation unit 16A composed of about 20 small keys, and converted into a digital signal by the key input controller 16B. Data and / or radio signals compliant with the Internet protocol are received from the public network by the communication antenna 111A, and the data converted into digital signals by passing through the RF transceiver 111B and the baseband processor 11, The data is transferred to the central processing circuit 1_10A1 via the bus 19. The central processing circuit 1_10A1 performs necessary processing based on the program stored in the flash memory 14A, and the processed data is sent via the bus 19 to the flash memory 14A and the RAM (Random Access Memory) 14B or graphics. The data is transferred to the controller 1_10B and the baseband processor 11. Finally, an image is displayed on the LCD panel 15A, sound is output from the speaker 18B, a radio signal is transmitted from the communication antenna 111A, and data is stored in the flash memory 14A.
Note that transmission / reception of radio signals compliant with the Internet protocol can be realized by various communication methods as in the case of voice communication. At that time, by enabling the communication antenna 111A, the RF transceiver 111B, and the baseband processor 11 to cope with radio signals in multiple bands, for example, at locations close to wireless LAN base stations and access points such as indoors It is possible to realize communication using the wireless LAN method of the above, and communication using third-generation mobile communication (cellular system) such as the CDMA method in other locations.

In particular, when the mobile phone 1 accesses a website connected to the Internet and browses a web page constituting the website, the central processing circuit 1_10A1 follows the browser program stored in the flash memory 14A. Via the communication antenna 111A, the RF transceiver 111B, the baseband processor 11 and the bus 19, the mark-a document file and its link file constituting the web page are acquired, and depending on the layout format of the web page, as follows: Generate and send drawing commands to That is, if the web page adopts a liquid layout or a fixed-width layout narrower than the screen horizontal resolution (240 pixels) of the LCD panel 15A, a page image having the same number of horizontal pixels as the screen horizontal resolution of the LCD panel 15A. If the web page adopts a fixed width layout wider than the screen horizontal resolution of the LCD panel 15A, a drawing command for generating a page image having the same number of horizontal pixels as the fixed width is generated and the drawing command is generated. The instruction is transmitted to the graphic controller 1_10B.
The graphic controller 1_10B generates bitmap data on the virtual screen based on the drawing command and writes it into the VRAM 1_10C, and displays bitmap data that is displayed on the LCD panel 15A and describes an image having the same resolution as the screen resolution of the LCD panel 15A Cut out from VRAM1_10C and transmit to 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.
At this time, if the resolution of the page image is larger than the screen resolution of the LCD panel 15A, the central processing circuit 1_10A1 draws according to the data input by operating the key responsible for the screen scroll function in the key operation unit 16A. By changing the instruction, the bitmap data cut out from the VRAM 1_10C gradually transitions on the virtual screen, and as a result, the page image is scroll-displayed on the LCD panel 15A.

When the mobile phone 1 is used for viewing TV programs, the TV broadcast signal received by the TV receiving antenna 112A is converted into a digital video signal and a digital audio signal by the TV tuner 112B and the AD / DA converter 1_112C. Then, the data is transmitted to the central processing circuit 1_10A1 via the bus 19.
In the mobile phone 1, an image of a television broadcast is displayed with the LCD panel 15A placed vertically (→ vertically long screen (number of horizontal pixels × number of vertical pixels = 240 × 320 pixels)) or displayed horizontally ( → Landscape (number of horizontal pixels × number of vertical pixels = 320 × 240 pixels) can be selected by operating the key operation unit 16A, and the central processing circuit 1_10A1 receives input signals and Based on the digital video signal, generates a drawing command to create bitmap data of the screen image displayed on the LCD panel 15A (however, in the case of a portrait screen, a screen image in which a non-display area is generated at the top and / or bottom) Then, the drawing command is transmitted to the graphic controller 1_10B. At this time, the horizontal / vertical pixel number of the original image in the television broadcast is larger than the horizontal / vertical pixel number of the LCD panel 15A in both of the portrait screen and landscape screen. By drawing a part of the digital moving image signal transmitted from the DA converter 1_112C, a drawing command for the entire image of the low resolution image is generated.
The operations of the graphic controller 1_10B, the VRAM 1_10C, and the LCD driver 15B operate in the same manner as when displaying a page image of a web page, except that there is no image scrolling according to the operation of the key operation unit 16A. A television broadcast video is displayed in real time on the LCD panel 15A.
On the other hand, the digital audio signal is also appropriately processed by the central processing circuit 1_10A1, and further outputted as sound from the speaker 18B by passing through the baseband processor 11 and the CODEC 18C. As a result, it can be viewed as a television program together with the moving image displayed on the LCD panel 15A.

Further, when the mobile phone 1 is used for photographing a subject, an optical signal reflected or emitted from the subject is converted into a digital moving image signal through the same path as in the case of communication with a mobile videophone, and is sent to the central processing circuit 1_10A1. Sent. The central processing circuit 1_10A1, the graphic controller 1_10B, the VRAM1_10C, and the LCD driver 15B operate in the same manner as when viewing a TV broadcast program. As a result, the video (moving image) of the subject is displayed on the LCD panel 15A in real time. .
At this time, since the number of horizontal / vertical pixels of the original image captured by the CCD 12B is larger than the number of horizontal / vertical pixels of the LCD panel 15A in both of the portrait screen and landscape screen, the central processing circuit 1_10A1 issues a drawing command. Is generated, a part of the digital moving image signal transmitted from the AD / DA conversion unit 2_12C is thinned to generate a drawing command for the entire image of the low resolution image.

On the other hand, the mobile phone 1 not only outputs the audio from the speaker 18B in real time based on the digital audio signal as described above, but also displays the video in real time on the LCD panel 15A based on the digital video signal. The digital audio signal and / or digital video signal is converted into a data file and stored, and the stored data file is read and subjected to necessary processing to output sound, display an image, or It can be played back as a combined movie.
When used for storing and reproducing such image data and / or audio data, the central processing circuit 1_10A1 accesses the flash memory 14A based on the data input by operating the key operation unit 16A, Write drawing commands by writing bitmap data converted from digital video signals and digital audio data converted from digital audio signals as a compressed data file as necessary, or by reading the data file and performing necessary processing. The graphic controller 1_10B is output, or the digital audio signal is output to the CODEC 18C via the baseband processor 11.
Note that the image data file and / or the audio data file are accessed via the website, and digital signals received / converted via the communication antenna 111A, the RF transceiver 111B, and the baseband processor 11 are transmitted via the bus 19. The central processing circuit 1_10A1 can also receive and store it by performing necessary conversion and writing it to the flash memory 14A. However, since the capacity of the flash memory 14A is limited, for example, there is a restriction in storing a long movie or the like.
In addition, when storing image data that is a moving image, the image data that is a still image is stored in an MPEG standard format such as MPEG (Moving Picture Experts Group) -1, MPEG-2, or MPEG-4. In some cases, the file is stored in a format such as BMP, TIFF, JPEG, GIF, or PNG. The audio data is stored in the WAVE format, MP3 (MPEG Audio Layer 3), AIFF (Audio Interchange File Format), ATRAC3 (Adaptive TRansform Acoustic Coding 3), or the like.

  The above is the outline of the function when the mobile phone 1 is used alone, but the mobile phone 1 includes the external connection terminal portion A_13D for connecting to the connection unit 3, and the external connection terminal portion A_13D, The mobile phone 1 and the connection unit 3 can be operated as an integrated information communication system by connecting the external connection terminal B_33D constituting the interface unit B_33 provided in the connection unit 3 via the connection cable 2. It becomes like this.

On the other hand, the connection unit 3 includes an interface unit C1_35 and an interface unit C2_36 for connecting to peripheral devices. The interface unit C1_35 includes an external display device 5 that is an LCD, and the interface unit C2_36 includes a full keyboard. An external keyboard 61 and a mouse 62 are connected to each other. The connection unit 3 includes an HDD 34 and a rechargeable battery B_37A, and each is connected to the interface unit B_33. In addition, an AC / DC circuit 37B and a commercial power plug 37C are connected to the rechargeable battery B_37A, and the connection unit 3 is operated by direct current power temporarily stored in the rechargeable battery B_37A via them. The DC power stored in the rechargeable battery B_37A of the connection unit 3 is supplied to the built-in rechargeable battery 17 of the mobile phone 1 via the external connection terminal portion B_33D and the external connection terminal portion A_13D, and is stored once. Used for the operation of the mobile phone 1.
In the following, the screen resolution of the external display device 5 (LCD) will be described as a VGA size (the number of horizontal pixels × the number of vertical pixels = 640 × 480 pixels) as a general rule. Good.

Now, the external display device 5 is connected to the operating mobile phone 1 and the interface unit C1_35, and the connection unit 3 is operating (hereinafter, “the external display device 5 is connected to the interface unit C1_35 and is operating”). Is abbreviated as “active”), the mobile phone 1 in operation is connected to the connection unit 3 and the connection unit 3 is activated, or the connection unit 3 in operation of the mobile phone 1 When the mobile phone 1 is started up, the central processing circuit 1_10A1 of the mobile phone 1 detects from the connection unit 3 that the connection unit 3 is connected (hereinafter abbreviated as a connection detection signal). ), And the screen resolution data of the external display device 5 connected to the interface unit C1_35 of the connection unit 3, the external connection terminal unit B_33D, the connection cable 2, and the external connection terminal Received via the part A_13D and the bus 19.
When the central processing circuit 1_10A1 of the mobile phone 1 receives the connection detection signal, the central processing circuit 1_10A1 will be described below in place of the image drawing command corresponding to the screen horizontal resolution or screen resolution of the LCD panel 15A. In this manner, an image drawing command having a resolution larger than the screen resolution of the LCD panel 15A is generated and transmitted to the graphic controller 1_10B. Further, the central processing circuit 1_10A1 generates a transmission command that instructs the TMDS transmitter 13A to transmit the bitmap data cut out from the VRAM1_10C to the LCD driver 15B together with the above drawing command instead of transmitting it to the LCD driver 15B. The instruction is transmitted to the graphic controller 1_10B.

  First, when a website connected to the Internet is accessed and a web page constituting the website is being browsed, the central processing circuit 1_10A1 follows the browser program stored in the flash memory 14A to lay out the web page layout. A drawing command is generated and transmitted as follows according to the format. That is, if the web page adopts a liquid layout or a fixed-width layout narrower than the screen horizontal resolution (640 pixels) of the external display device 5, the page has the same number of horizontal pixels as the screen horizontal resolution of the external display device 5. If a web page adopts a fixed-width layout wider than the screen horizontal resolution of the external display device 5, an image drawing command is generated and transmitted, and a page image drawing command having the same number of horizontal pixels as the fixed width is generated. Generate and send.

  When the functions described here and the functions described in the above [0122] are combined, the central processing circuit 1_10A1, the graphic controller 1_10B, and the VRAM1_10C constituting the data processing means can be used when the web page adopts a liquid layout. , By processing the same markup document file, when using the mobile phone 1 alone and when using it as an integrated information communication system with the connection unit 3 to which the external display device 5 is connected, Bitmap data corresponding to different page images is generated and transmitted. That is, when used alone, an integrated system generates and transmits bitmap data corresponding to a page image (same width page image) that is line-breaked according to the screen horizontal resolution of the LCD panel 15A of the mobile phone 1. When used as, bitmap data corresponding to a page image (wide page image) to be lined up in accordance with the horizontal resolution of the screen of the external display device 5 is generated and transmitted.

  In this embodiment, when the web page adopts a fixed-width layout, the central processing circuit 1_10A1 uses the same fixed-width line feed when used alone or as an integrated system. Generates and transmits page image drawing commands, but stores a browsing program having a plurality of rendering modes in the flash memory 14A, and when used alone, for example, by dividing the frame format into a plurality of tab pages. It is possible to generate and transmit a drawing command for a page image (wide page image) that is laid out so as to line feed in accordance with the horizontal resolution of the screen of one LCD panel 15A. Even in such a case, the data processing means generates both a digital display signal of the same width page image and a digital display signal of the wide page image by processing the same markup document file. .

  On the other hand, when viewing a television broadcast and photographing a subject, the resolution of the original image in the digital moving image signal transmitted from the AD / DA conversion unit 1_112C and the AD / DA conversion unit 2_12C, respectively, is Since the screen resolution of the external display device 5 is still larger, the central processing circuit 1_10A1 draws a part of the digital moving image signal to draw a low-quality overall image rendering command that matches the screen resolution of the external display device 5 Is generated and transmitted.

  Note that when communicating with a mobile videophone, the original image resolution of the wireless video signal in the mobile videophone does not exceed the screen resolution of the LCD panel 15A, so the mobile phone 1 is connected to the connection unit 3. Even in this case, the resolution of the image that the drawing command from the central processing circuit 1_10A1 commands to draw does not change. However, if the flash memory 14A stores an image interpolation program and the central processing circuit 1_10A1 operates accordingly, it is the same as the screen resolution of the external display device 5 (greater than the original image resolution of the wireless video signal). A drawing command for an image having a resolution can be generated and transmitted.

By the way, instead of the external display device 5 having a screen resolution of VGA size, the screen resolution is sufficiently large, such as a full high-definition television monitor (the number of horizontal pixels × the number of vertical pixels = 1920 × 1080 pixels). When using a virtual screen having a preset virtual screen logical resolution (3840 × 2400 pixels), the rendering command generated and transmitted by the central processing circuit 1_10A1 changes as follows.
First, when browsing web pages, most web pages have a fixed width that does not exceed the screen horizontal resolution of the external display device 5, even if a fixed width layout is adopted. In the arithmetic circuit 1_10A1, a page image drawing command having the same number of horizontal pixels as the screen horizontal resolution of the external display device 5 is generated and transmitted.
Next, even when viewing a television broadcast or shooting a subject, the resolution of the original image in the digital moving image signal does not exceed the screen resolution of the external display device 5, so the central processing circuit In 1_10A1, an original image drawing command in the digital moving image signal is generated and transmitted.
At that time, when the TV broadcast being viewed is an analog TV broadcast, or when the resolution of the CCD12B (1280 × 1024 pixels) is smaller than the full high-definition size (1920 × 1080 pixels) as assumed in this explanation. The resolution of the original image from which the drawing command is generated is smaller than the screen resolution of the external display device 5, but the flash memory 14A stores the image interpolation program and the central processing circuit 1_10A1 operates accordingly. Can generate an image rendering command having the same resolution as the screen resolution of the external display device 5 (greater than the resolution of the original image of the digital moving image signal).

  Based on the drawing command received from the central processing circuit 1_10A1, the graphic controller 1_10B generates bitmap data on a preset virtual screen and writes it into the VRAM 1_10C. Further, the graphic controller 1_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 1_10A1, and is displayed on the screen of the external display device 5. Is extracted from VRAM1_10C. Then, based on the transmission command received from the central processing circuit 1_10A1, the bitmap data is transmitted to the TMDS transmitter 13A, and the TMDS transmitter 13A transmits the bitmap data to the connection unit via the external connection terminal A_13D. 3 is transmitted to the interface part B_33 of 3 by the TMDS transmission method.

  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. At that time, when browsing a web page that adopts a liquid layout or a fixed width layout that is narrower than the screen horizontal resolution of the external display device 5, the entire horizontal image of the page image is displayed. However, if you are browsing a web page that uses a fixed-width layout that is wider than the screen horizontal resolution of the external display device 5, the page image is displayed on the screen of the external display device 5. Only a part in the horizontal direction is displayed, and the entire page image can be browsed by performing horizontal scrolling. On the other hand, when watching a television broadcast or photographing a subject, an image having a resolution lower than the original image of the digital moving image signal is displayed on the full screen.

However, when a high-resolution display device such as a full high-definition television monitor is employed as the external display device 5 as described above, an image displayed on the external display device 5 changes as follows.
First, when browsing a web page, for the reasons described above, the page image of most web pages is displayed in its entirety in the horizontal direction and can be browsed without scrolling horizontally.
Next, when watching a TV broadcast, photographing a subject, or communicating with a mobile videophone, as described above, in a normal case, the central processing circuit In 1_10A1, the original image is displayed on the screen of the external display device 5 in response to the generation and transmission of the original image drawing command in the digital moving image signal. At that time, if the interface unit C1_35 in the external display device 5 or the connection unit 3 has an up-scan conversion function, the original image is displayed over the entire screen of the external display device 5, otherwise, the center of the screen is displayed. Only the part or the part biased to any of the four corners is displayed as a display area, and the other part is displayed as a non-display area (however, an external display device 5 Is a full high-definition monitor, the image is originally displayed on the entire screen of the external display device 5 even when the interface unit C1_35 does not have the up-scan conversion function). In either case, the resolution of the image displayed on the screen of the external display device 5 remains unchanged from the original resolution.
On the other hand, in the case where the flash memory 14A stores the image interpolation program and the central processing circuit 1_10A1 operates in accordance with the program, it generates and transmits an image drawing command having the same resolution as the screen resolution of the external display device 5. In this case, an image having a resolution larger than the original resolution is displayed over the entire screen of the external display device 5.

Even when the image data is reproduced on the screen of the external display device 5, the functions of the central processing circuit 1_10A1, the graphic controller 1_10B, the TMDS transmitter 13A, etc. are basically the same as the functions in other applications.
Depending on the magnitude relationship between the resolution of the original image data and the resolution of the external display device 5, the presence or absence of an interpolation program, whether or not the external display device 5 or the connection unit 3 has a multi-scan function, etc. An image, an image that has become low resolution by thinning pixels from the original image, or an image that has become high resolution by interpolating pixels to the original image is displayed over the entire screen of the external display device 5, It may be displayed in the display area of the center part of the screen or the part biased to either of the four corners.

  When the central processing circuit 1_10A1 of the mobile phone 1 receives the connection detection signal, the central processing circuit 1_10A1 does not accept the input signal from the key operation unit 16A of the mobile phone 1 to the key input controller 16B. Then, an input source instruction signal for accepting 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 output. 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.

In addition, the central processing circuit 1_10A1 of the mobile phone 1 is based on 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 and the external connection terminal unit By accessing the HDD 34 via the A_13D, the connection cable 2 and the interface unit B_33 of the connection unit 3, the bitmap data and the digital audio data are written as a compressed data file as necessary, and the data file is read out. By performing necessary processing, the rendering command is output to the graphic controller 1_10B, and the digital audio signal is output to the CODEC 18C via the baseband processor 11. Further, the central processing circuit 1_10A1 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 unit 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 1_10B and the designation (switching) of the data input source to the central processing circuit 1_10A1 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.

  Further, in this embodiment, even when the mobile phone 1 is connected to the connection unit 3, the sound when watching a TV broadcast program or playing a recorded movie is transmitted from the speaker 18B on the mobile phone 1 side. Output by adding necessary interface means to both the mobile phone 1 and the connection unit 3, adding an audio decoder to the connection unit 3, and then connecting a high performance external speaker to the connection unit 3. It is also possible to output high quality sound from an external output.

  On the other hand, FIG. 2 shows that after connecting the portable information communication device and the portable information communication device connection unit according to the first embodiment of the present invention, an external display device and an external input device are connected to the connection unit.

As a result, connectors and cables can be procured at low cost.

  Further, the connection unit 3 also has a commercial power plug 37C. The AC power supplied by inserting the commercial power plug 37C into the commercial AC power outlet 7 is supplied to the built-in AC / DC circuit 37B (shown in FIG. 2). 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. 2) of the mobile phone 1 can be charged.

  1 and 2, the mobile phone 1 and the connection unit 3, the connection knit 3, the external display device 5, and the external input device (external keyboard 61 and mouse 62) are directly connected to each other between the connection cable and the external connection terminal portions. Although connected by contact, wireless means such as Bluetooth and IrDA (Infrared Data Association) standards can be used instead.

  On the other hand, FIG. 3 shows that after connecting the portable information communication device and the portable information communication device connection unit according to the first embodiment of the present invention, an external display device and an external input device are connected to the connection unit. FIG. 2 is an explanatory diagram for explaining exchange of information between an information communication system configured by the above and a web server connected to the Internet, and particularly describes a case where the portable information communication device is a mobile phone. .

  When an information communication system comprising a mobile phone 1, a connection unit 3, an external display device 5 and external input devices (external keyboard 61 and mouse 62) accesses a web server 91 connected to the Internet 9, the mobile phone 1 The central processing circuit 1_10A1 transmits a user agent to the web server 91 via the bus 19, the baseband processor 11, the RF transmission / reception unit 111B, and the communication antenna 111A according to the browser program stored in the flash memory 14A ( The components of the mobile phone 1 are not shown in FIG. 3). In addition, the browser program stored in the flash memory 14A has a frame-compatible function capable of appropriately configuring a screen image from a plurality of web files that constitute a frame display web page.

At this time, the central processing circuit 1_10A1 gives the user agent the bitmap data extracted from the VRAM 1_10C to the graphic controller 1_10B together with information indicating that the mobile phone 1 has a function of transmitting a high resolution external display signal. Information that can specify whether it is instructed to transmit to 15B or to instruct to transmit to TMDS transmitter 13A is included.
On the other hand, the web server 91 is a data file set (hereinafter referred to as a mobile phone) consisting of a markup document file and its link file corresponding to a web page that is small in size and assumed to be viewed on an attached display of a mobile phone and does not use a frame display. And a data file set (abbreviated as a PC file set) corresponding to a web page that is assumed to be viewed on a personal computer and has no restrictions on size or format. In addition, by having a CGI or PHP function, the mobile phone 1, the connection unit 3, and the external display are selected based on information related to a transmission command from the information included in the user agent. The data is transferred to the information communication system including the device 5 and the external input device (external keyboard 61 and mouse 62). That is, if the transmission command from the central processing circuit 1_10A1 commands transmission to the LCD driver 15B, the file set for mobile phones is ordered. If the transmission command to the TMDS transmitter 13A is commanded, the file set for personal computers is selected. , Send each.
