The present invention relates to a mobile information communication apparatus such as a mobile telephone unit, a connection unit used along with a mobile information communication apparatus, and an external input/output unit used along with a mobile information communication apparatus.
Due to recent advance of electronics, and information and communication technology, a mobile handset for operating in mobile telephone system including PHS (Personal Handyphone System), PDA (Personal Digital Assistant) and other mobile information communication apparatuses, which send or receive data by wireless communication, have become multifunctional, so that it comes normally equipped with a web browsing function, as well as with an e-mail sending and receiving function, which enables to acquire document files described by markup language and their linked files from a web server connected to the Internet, and to display texts and images in a proper layout on its own attached display means which usually is a liquid crystal display panel.
Hereinafter, “a mobile handset for operating in mobile telephone system including PHS” is referred as “a mobile telephone unit”, and “a document file described by markup language” is referred as “a markup document file”.
Many mobile telephone units also have a game function, by which one can enjoy a change of image displayed on their own attached display by manually operating its own attached key operating part to activate a program, which is downloaded from a web site and is stored in a storage means such as a flash memory, and to input required data. Moreover, some mobile telephone units have a television tuner function to receive a wireless signal of television broadcast and to display a picture of a TV program on their own attached display.
Hereinafter, “a wireless signal of television broadcast” is referred as “a TV signal” in the followings.
Especially since a digital terrestrial broadcast is scheduled to start, it is expected that merging of a digital television tuner function and a web browsing function in a mobile telephone unit enable to provide a user of the mobile telephone unit with a service taking both advantages of a concurrent broadcast and the Internet with personal and interactive characteristics.
Under these circumstances, a display function of image including a text and a picture is thought to be more important in a mobile information communication apparatus centering on a mobile telephone unit. However, a mobile telephone unit and other mobile information communication apparatuses cannot have large size display means because of a constraint of portability. Thus, in the case of a mobile telephone unit, screen's size is around 2.5″ at maximum and screen's resolution is QVGA (Quarter Video Graphics Array). Note that because a mobile telephone unit is usually used in a vertically long configuration, QVGA means “horizontal×vertical=240×320 pixels”.
When a mobile information communication apparatus receives a long e-mail of which a sentence extends in many lines and does not fall once in its own attached display screen due to a screen constrain, an e-mail receiver using the apparatus has to roll down the screen and cannot understand the meanings of the text smoothly as a result. On the other hand, an e-mail sender has to make his e-mail, which is addressed to a mobile information communication apparatus, short enough considering such screen constraint of a receiver, even though the sender uses a desktop or a notebook personal computer system of which display screen is large enough to display long text without any problem.
Hereinafter, “a desktop or a notebook personal computer system” is referred as “a PC”.
Moreover, it is more constrained to browse a web page by using a mobile information communication apparatus than to read e-mail by using it. A web page intended to be browsed with a PC is usually composed of document files described by HTML (Hyper Text Markup Language) and their linked files.
Hereinafter, “a web page intended to be browsed with a PC” is referred as “a web page for PC”, and “a document file described by HTML” is referred as “an HTML file”.
However, it is impossible to properly browse a web page described by full-spec HTML by using an average mobile telephone unit partly because the screen's size and resolution of its own attached display means is short. It is possible only to browse a web page of so called “mobile site”, which is described by a markup language specialized for a mobile information communication apparatus such as CHTML (Compact HTML), HDML (Handheld Device Markup Language) and WML (Wireless Markup Language). Thus, a web page composed of HTML files and their linked image files with high resolution is scarcely able to be displayed properly, and a mobile telephone unit is sometimes rejected by an administrator to access a web site including web page with frame layout, where a screen is divided into some frames with separate URL (Uniform Resource Locator).
Recently, mobile telephone units with “a full browser function” or “a PC site view function”, with which a web page for PC can be browsed are on sale, but in many cases the same screen image as that is displayed on a PC screen and is originally intended by a web page creator is not displayed, since particular kind of rendering mode is taken such that image size is reduced to fit a screen's resolution of a mobile telephone unit that is 240 pixels in the case of vertically long QVGA, text moves to next line according to screen width, or each frame is displayed in a separate page in the case of a frame layout web page.
Some mobile telephone unit takes such rendering mode as to display a web page for PC in similar layout as displayed in a PC screen, but a web page for PC is created to target VGA screen (horizontal×vertical=640×480 pixels) at lowest, so it is difficult to understand the whole meaning of a web page because a whole page cannot be browsed without a frequent horizontal scrolling.
Hereinbefore and hereinafter, “a whole of image displayed in full screen on a display screen” is referred as” “a screen image”. Therefore, for example, when a web page composed of a document file described by markup language and its linked image files is browsed and displayed in full screen, “a screen image” is a whole of a image including all of the document text, all of the individual images corresponding to the image files, and even various menu displays of browser software.
Note that, for example, when a screen image data of VGA is inputted to a display device to meet only screen mode of XGA (eXtended Graphics Array) (horizontal×vertical=1024×768 pixels) and image is displayed only in center of the screen (or in some corner), “a screen image” means a display of the display area excluding non-display area.
By using a mobile information communication apparatus, on the other hand, one can enjoy only a relatively simple game, which can be displayed in its own attached small size display means. Since, therefore, almost all games of so-called “mobile appli” were created one or more generations ago in the field of games for a specialized game machine or a PC, they are enjoyed only for time killing in a short time.
Also, when one watches a TV program by using a mobile telephone unit of which display has a resolution of QVGA at highest, it is required to thin out pixels, because effective scanning lines required by a TV broadcast, which is equivalent to vertical resolution and is 480 in the case of an analog TV broadcast, is larger than a vertical resolution of a display means belonging to a mobile telephone unit, which is 240 pixels when a mobile telephone unit is used in a horizontally long configuration (horizontal×vertical=320×240 pixels) to watch in as large a screen as possible. Especially in the case of a digital TV broadcast, effective horizontal resolution is regulated as well as number of effective scanning lines (vertical resolution). In 480i mode, of which resolution is the lowest, horizontal resolution and vertical resolution is 720 pixels and 480 pixels respectively, and in 1080i, that is so-called “full high vision”, horizontal resolution and vertical resolution is 1920 pixels and 1080 pixels respectively. Anyway, a mobile telephone unit, of which display means has a resolution of QVGA at highest, cannot display an intrinsic image of a TV broadcast in full screen but can display only a poor image with a lower resolution than an intrinsic resolution.
Wherein “an intrinsic image of a TV broadcast” means “an image with an intrinsic resolution, which is displayed, when a TV signal is properly processed by a television receiver (TV receiver) with a sufficient tuner and display function”.
Many users of a mobile information communication apparatus possess a PC in addition to the mobile apparatus. Such a user uses a PC when he sends and receives a long e-mail, browses a web page for PC or enjoys a complex game of which graphics can be displayed only in large size screen. And a mobile information communication apparatus is utilized only for sending and receiving a short e-mail and browsing a web page of “mobile site”. In other case, only a wireless communication means of a mobile information communication apparatus, which is connected to a PC, is utilized to connect a network and data, which is acquired by using the wireless communication means, is processed only by a PC. Also, recently “AV (Audio Visual)-PC” is on sale, which has a function which enables a user to watch a TV program by using a built-in television tuner. In such a case that both of “AV-PC” and a mobile telephone unit with a television tuner are possessed, a TV program is watched by a mobile telephone unit outside or in traveling time and is watched by “AV-PC” home or in one's room.
Since, however, a PC is usually designed for a versatile use that is not restricted to sending and receiving of e-mail or browsing of web page, which can be conducted by a mobile information communication apparatus, it has a higher-performance processor, such as CPU (Central Processing Unit) or so on, than a data processing means of a mobile information communication apparatus. Moreover, it is required to prepare software, such as OS (Operating System) or so on, to activate hardware. Thus, it takes more cost to possess a PC than it does to possess a mobile telephone unit or another mobile information communication apparatus.
Therefore, it is economically irrational for major users, whose usage of a mobile information communication apparatus is restricted to sending and receiving of e-mail or browsing of web page except a telephone call, to possess a PC in order only to avoid inconvenience in reading a long e-mail or browsing a web page for PC due to short screen's size and resolution of a display means belonging to a mobile information communication apparatus.
On the other hand, although a data processing means of a mobile information communication apparatus does not have all functions as a PC's processor such as CPU, as far as a display data processing function to display an image on its own attached display means is concerned, it has a comparable function as that of a PC's processor, except that the display screen is small. Thus, it is not desirable from the viewpoint of effective resource to use both a PC and a mobile information communication apparatus as described above, because it results in low operating rate of one machine at least and it means overlapping investment to similar items.
Similar problem of “irrational overlapping investment” and “inefficient resource use” occurs in the case that a mobile information communication apparatus has a television tuner function. Because a television tuner circuit, which receives and converts a TV signal to digital data, is required in order to enjoy audio and visual of a TV program. On the other hand, an average user of a mobile information communication apparatus usually possesses a TV receiver or “AV-PC” with a larger screen besides a mobile information communication apparatus, since display means belonging to the mobile apparatus is poor both in size and in image quality. Thus, the user is forced to possess both television tuner circuit in a mobile information communication apparatus and that of a TV receiver or “AV-PC” and that results in low operating rate of one television tuner at least.
In the case of a digital terrestrial broadcast, simple overlapping investment seams not to occur because a television tuner of a TV receiver and that of a mobile information communication apparatus are different in specification, since segments (high-vision broadcast) or 4 segments (normal broadcast) out of 13 segments comprising one channel are assigned to a normal TV receiver and 1 segment is assigned to a mobile information communication apparatus. As a result of development of electrical and information technology, however, it is probable that a tuner receiving 12 segments or 4 segment broadcast, which is intended to be received by a normal TV receiver at present, will be installed in a mobile information communication apparatus, and, if then, similar problem of “irrational overlapping investment” and “inefficient resource use” will occurs in the field of a digital television tuner, which is expensive on the current level of technology.
Because of such a situation, it is recognized as an issue that, by using a mobile information communication apparatus not a PC, a long e-mail, a web page for PC, a highly entertaining game and a moving image of TV program is displayed in a larger screen, keeping the size of its own attached display means the same as present not to harm its portability. Especially, as for a web page for PC, it is an issue that a screen image similar to that of PC is displayed, and as for a TV program, it is an issue that an intrinsic image of a TV broadcast is displayed in full-screen.
In order to solve such an issue, some technologies are disclosed to display an image in a larger-screen external display device than a display means belonging to a mobile information communication apparatus by connecting the larger-screen external display device to the mobile information communication apparatus.
Hereinafter, “an external display device with a larger screen than a display means belonging to a mobile information communication apparatus” is referred as “an larger-screen external display device”.
And such technologies are categorized into the following three types:
The 1st types of technologies are disclosed for example in Patent Document 1, Patent Document 2, Patent Document 3 and Patent Document 4.
The technologies disclosed in these patent documents do not require to use a PC separately from a mobile information communication apparatus but some connection unit with a display data processing means such as a processor (in Patent Document 1), a CPU (in Patent Document 2), a reading control circuit (in Patent Document 3) and a display control circuit (Patent Document 4) instead. Such a display data processing means has a function only to display characters and images on the screen and is not versatile as a CPU and other processors or OS and other software of PC. Thus, it is possible that a cost of a connection unit with a display data processing means is cheaper than that of a PC, and it is more economically acceptable to possess such a connection unit than to possess a PC in addition to a mobile information communication apparatus.
Even though, a user still possesses each display data processing means with almost the same display data processing function to display images and characters both in the mobile information communication apparatus and in the connection unit except that the size of screens, on which images are displayed, are different. In this case, therefore, similar problem of “irrational overlapping investment” and “inefficient resource use” will also occur as in the case to use a PC in addition to a mobile information communication apparatus. And it is realistically possible that purchases cost of a connection unit will be the same as that of a PC or higher than that of PC.
On the other hand, the 2nd types of technologies are disclosed for example in Patent Document 5, Patent Document 6, Patent Document 7, Patent Document 8 and Patent Document 9.
This type of technologies does not require a PC or a connection approximately equivalent to a PC. However, it is required that an image display device with a display data processing means such as a control system (a micro computer) (in Patent Document 5), a control part 5 (in Patent Document 6, which is different from a control part 10 in wireless telephone), a high definition convert part and a display processing part (in Patent Document 7), an expanding circuit and a display circuit (in Patent Document 8), or a CPU (in Patent Document 9), since, in this case, a commonly used display device such as TV monitor cannot be used as it stands.
The a technology categorized in the 3rd type is also disclosed in Patent Document 6, and in the technology control part 10 in a wireless telephone has an additional display data processing function. Thus, a control part 15 in a larger-screen external display device (a mobile display) only sends display data inputted from connector terminal 13 to a liquid crystal display panel belonging to a mobile display, so that it does not have any display data processing function. This technology will be discussed in the paragraph where the 3rd type of technology is discussed.
Since, in the 2nd types of technologies, each display data processing means with almost the same function is equipped both in a mobile information communication apparatus and in a larger-screen external display device as described above, the problem of “irrational overlapping investment” and “inefficient resource use” also occurs. And since purchases cost of an image display device with such a display data processing means will be surely more expensive than that of a commonly used CRT (Cathode Ray Tube) display device and a normal liquid crystal display device, a similar irrational economic burden as occurs in when a PC is additionally used or the 1st type of technology is adopted, which should be avoided, also occurs.
On the other hand, the 3rd type of technology does not use a connection unit or a special image processor and is comprised only of a mobile information communication apparatus and a commonly used larger-screen external display device without any special functions. Thus, in general, the 3rd type of technology is supposed to be more unlikely to yield the problem of “irrational overlapping investment” and “inefficient resource use” than the 1st and the 2nd type of technology.
A mobile telephone unit with so-called “TV output function” or “AV output function” is commercially available, which is categorized in the 3rd type of technology. In such a mobile telephone unit, the mobile telephone unit is connected to a TV monitor via special cable of which telephone side terminal is a special connecting terminal and of which monitor side terminal is a video terminal and it is possible to display a still image and a moving image, which are taken by using its own attached digital camera function, and certain games on a TV monitor, of which screen is larger than that of a display means belonging to the mobile telephone unit. In this case, however, a resolution of an image displayed on a TV monitor is the same as screen's resolution of a display means belonging to a mobile telephone unit (QVGA at largest) so that a small image is displayed in the center of TV monitor or expanded image with poor quality is displayed in full screen.
At present, only still images and moving images, which are taken by a mobile telephone unit itself, or certain games are displayed on a TV monitor. Even though, however, such a mobile telephone unit has “a full browser function” or “a PC site view function” and a browsed web page for PC is displayed on a TV monitor, the same screen image as displayed on its own attached display means should be only enlarged without increasing image resolution. Therefore, a display in the same layout as that is realized on a PC screen and is originally intended by a web page creator should not be realized on a TV monitor. Moreover, even though, such a mobile telephone unit has a television tuner function and a received image is outputted to a TV monitor, an intrinsic image of a TV broadcast should not be displayed on a TV monitor.
Therefore, in order to solve the above issue, it is not sufficient for a mobile information communication apparatus to have such a function to enlarge an image, which is displayed on its own attached screen, and to display it on a larger-screen external display device as a mobile telephone unit with “TV output function” or “AV output function”. It is necessary to provide a mobile information communication apparatus with a function that an image with a higher resolution than a screen's resolution of its own attached display means can be displayed on a larger-screen external display device.
If such a mobile information communication apparatus is provided, a whole image with an intrinsic resolution can be displayed on an external display with a larger screen, even if only a part image or a whole image with poor quality, of which pixels are thinned out, can be displayed on its own attached display panel. Especially, if a mobile information communication apparatus has a function to display an image of which horizontal pixels is larger than the horizontal resolution of its own display screen, number of characters can be increased which can be displayed in a line. Herewith, text does not extend in many lines nor is necessary to be rolled down frequently, even when the mobile information communication apparatus receives long e-mail. By synthesizing these effects, a web page for PC is displayed on a larger-screen external display device in the same layout as is realized on a screen of a PC.
The 3rd types of technologies, which are intended to solve issues similar to the above issue, are disclosed, for example, in Patent Document 6, Patent Document 10, Patent Document 11, Patent Document 12 and Patent Document 13.
In Patent Document 10 and Patent Document 11, it is disclosed that a TV receiver including a digital TV receiver is selected as a larger-screen external display device, and a video circuit and a video terminal, an interface circuit and a connector, or a transmitter circuit and an antenna (these all in Patent Document 10), or a neighborhood communication means (part) (in Patent Document 11) are provided as interface means between a mobile information communication apparatus and a larger-screen external display device. In these documents, however, a mechanism is not described at all how to display screen images with different information amount on display (display part) of a mobile telephone unit and on an external display with a larger screen, which have different screen sizes.
In Patent Document 11, in fact, it is disclosed that a control part 17 controls both a display part 11 and a neighborhood communication 18, but it is not disclosed at all by what mechanism said display part 17 should have in order that a screen image with less information amount is displayed on displayed part 17 and a screen image with more information amount is displayed on a digital TV 2, which sends and receives data between neighborhood communication 18. In Patent Document 10, on the other hand, it is suggested that a display actuating part controls a signal output to a (digital) TV receiver, but it is not disclosed at all how an image is displayed on a display means belonging to a mobile telephone unit.
On the other hand, in Patent Document 6 and Patent Document 12, it is disclosed that a mobile display (in Patent Document 6) or a CRT display (in Patent Document 12) is selected as a larger-screen external display device and an external interface (in Patent Document 6) or a monitor terminal (Patent Document 12) is provided as interface means. And also a mechanism is disclosed how to display a screen image with less information amount on a display part of a wireless telephone unit (in Patent Document 6) or a personal liquid crystal display panel of a mobile telephone unit (Patent Document 12) and to display a screen image with more information amount on a larger-screen external display device.
At first, in Patent Document 6, a control part 10 of a wireless telephone unit has a function to output display data of an image both to a display part 2 of a wireless telephone unit and to an external interface 3, and also has functions as enlargement means and enlargement control means and functions as linefeed means and linefeed control means. And it is described that an image, of which size is larger than that of image displayed in the display part 2 belonging to the wireless telephone unit, is displayed on a liquid crystal display 12 belonging to the mobile display and it is possible to increase number of characters displayed in one line.
However, additional functions disclosed in the document are restricted to functions related to image enlargement, which are already realized in a mobile telephone unit with “TV output function” or “AV output function”, and to functions related to a display of characters. It is impossible that solely by the technologies disclosed in Patent Document 6 that, for example, a whole image with an intrinsic resolution is displayed on an external display with a larger screen, if only a part image or a whole image with poor quality, of which pixels are thinned out, can be displayed on its own attached display panel. Therefore, the technology disclosed in Patent Document 6 cannot solve the issue completely to provide a mobile information communication apparatus with a function that an image with a higher resolution than a screen's resolution of its own attached display means can be displayed on a larger-screen external display device.
On the other hand, in Patent Document 12, it is disclosed that a display control circuit 21 has a function to send inputted display data separately both to a personal liquid crystal display panel 23 belonging to a mobile telephone unit and to a monitor terminal 25 connected to a CRT display under the control of a CPU 11. It is explained that, even if the amount of display data of image is too much to display the contents of display data on the personal liquid crystal display panel 23, all data is displayed on the CRT display without any deficiency according to this function.
This technology can seemingly solve the above issue to display a web page for PC on a larger-screen external display device in a similar image as that realized in a PC. Patent Document 12, however, has the following two problems.
Firstly, the mechanism for the display control circuit 21 to send display data separately both to the personal liquid crystal display panel 23 and to the monitor terminal 25 is not unknown. In Patent Document 12, there is a description saying “when display contents correspond to . . . ” or “when the destination of display data indicates . . . ”, but it is not disclosed at all by what mechanism the “correspondence” is judged or by what mechanism the “indication” is realized.
Secondly, it is not unworn what kind of image is displayed on the personal liquid crystal display panel 23 when display data corresponding to the CRT display 24 is inputted to the display control circuit 21 under the situation that the CRT display is not connected to the monitor terminal 25 and the mobile telephone unit is solely used. If, in such a situation, no image is displayed on the personal liquid crystal display panel 23, user convenience is reduced. If a part image is displayed on the personal liquid crystal display panel 2 and a whole image can be seen by screen scrolling, such mechanism to realize this is not disclosed at all.
Therefore, the technology disclosed in Patent Document 12 does not also solve the issue to provide a mobile information communication apparatus with a function to display an image with a higher resolution than a screen's resolution of its own attached display means on a larger-screen external display device.
Lastly, Patent Document 13 discloses the technology to provide a processor having a wide variety of functions in a telephone to display an image on a screen of a TV receiver that is a larger-screen external display device. The technology enables to display various information, including HTML contents comprising a web page for PC, on a large screen of a TV receiver and also is supposed to enable a web page for PC to be displayed on a larger-screen external display device in a similar image as that realized in a PC.
However, the processor installed in the telephone unit is high class enough to include various processors, such as a CPU 50a, a graphic processor, a sound processor and a DMA processor, and input/output ports. Moreover, the processor sole takes a role of image processing and, in contrast, a CPU 36 belonging to the telephone unit just takes a role of delivery of key input data and HTML contents data according to a request of the CPU 50a belonging to the processor. Thus, as for image processing, the situation is the same as the case that a mobile telephone unit and a PC are used at the same time and a wireless communication means of a mobile telephone unit is utilized only to connect to network.
Therefore, the technology disclosed in Patent Document 13 is formally categorized into the 3rd type, but there is no significant difference between 1st type and 2nd type of technology on the viewpoint of “irrational overlapping investment” and “inefficient resource use”.
The present invention is invented considering the abovementioned circumstances, and an object of the invention is to provide a mobile information communication apparatus which can display an image with a higher resolution than a screen's resolution of its own attached display means on a connected larger-screen external display device, without any special display data generating means for the larger-screen external display device being used separately from an originally equipped display data generating means, which is necessary to display an image on its own attached display means, but only with an addition of an interface means between the mobile information communication apparatus and the larger-screen external display device and a little addition of functions to its own display data generating means.
Hereinbefore and hereinafter, “display data generating means which is originally equipped to a mobile information communication apparatus and is necessary to display an image on its own attached display means” is referred as “its own attached display data generating means”.
Especially, as for a web page for PC, the present invention provides a mobile information communication apparatus, which can display a similar image as that realized in a PC and, it can be seen without frequent horizontal scroll.

In a mobile information communication apparatus according to any one of the first to the fifteenth invention, a higher-resolution image, which has a higher resolution than a screen's resolution of a display panel belonging to a mobile information communication apparatus, can be displayed on a high-resolution external display device connected to an interface means A1 of a mobile information communication apparatus, by sending a higher-resolution external display signal to the high-resolution external display device. Herewith, a whole image with an intrinsic resolution can be displayed on a high-resolution external display device, even if only a part image or a whole image with poor quality, of which pixels are thinned out, can be displayed on a display panel belonging to a mobile information communication apparatus. Since, especially, a function is realized to send a horizontally higher-resolution external display signal, of which a horizontal intrinsic number of pixels is larger than a screen's horizontal resolution of a display panel belonging to a mobile information communication apparatus, number of characters, which are displayed in a line of a high-resolution external display device, can be increased more than that in a line of a display panel belonging to a mobile information communication apparatus. Herewith, such a situation can be avoided that it is difficult to understand a long e-mail because its text extends in so many lines as to be rolled down frequently.
Moreover, a function to send a higher-resolution external display signal is realized only by a data processing means, which is indispensable to display an image on a display panel belonging to a mobile information communication apparatus, and an interface means, which is indispensable to be connected with an external display device. Therefore, it is not necessary for a mobile information communication apparatus to be equipped with a special display data generating means for an external display device, which is indispensable in conventional technologies, separately from a display data processing means which is originally equipped to a mobile information communication apparatus. Thus, the problem of “irrational overlapping investment” and “inefficient resource use” can be avoided.
Especially according to the second invention, a higher-resolution screen image can be displayed in full screen on a screen of a high-performance external display device, which has a multiscan function and has a high enough screen's resolution, by connecting the high-performance external display device to a interface means A1 of a mobile information communication apparatus. In the case, for example, a mobile information communication apparatus has a display panel with a screen's resolution of QVGA and has a function to send a higher-resolution external display signal of which intrinsic resolution is XGA (horizontal resolution:vertical resolution=4:3), a screen image of XGA, that is larger than a screen's resolution of a display panel belonging to a mobile information communication apparatus (QVGA), can be displayed in full screen on a screen of high-performance external display device, when the high-performance external display device, which has a multiscan function and has a screen's resolution of SXGA (Super XGA) (horizontal×vertical=1280×1024 pixels), is connected to a interface means A1 of a mobile information communication apparatus.
The same effect is also realized by connecting an interface means A1 of a mobile information communication apparatus and a high-resolution external display device via a connection unit which has a function to upscan an intrinsic resolution of a higher-resolution external display signal to a screen's resolution of a high-resolution external display device. In the case, for example, a mobile information communication apparatus has a display panel with a screen's resolution of QVGA and has a function to send a higher-resolution external display signal of which intrinsic resolution is XGA, and, on the other hand, a high-resolution external display device is a so-called “full high-vision TV monitor” (horizontal×vertical=1920×1080 pixels), a screen image of XGA, that is larger than a screen's resolution of a display panel belonging to a mobile information communication apparatus (QVGA), can be displayed in full screen on a screen of the full high-vision TV monitor, if the full high-vision TV monitor and the interface means A1 of a mobile information communication apparatus are connected with each other via a connection unit with a necessary upscan function.
Since, however, horizontal-vertical ratio of XGA and that of full high-vision size is different each other, there can be nothing to be displayed around both end of the screen. And a smooth image, of which resolution is larger than XGA, can be displayed by adding a pixel interpolation function to the connection unit.
On the other hand, especially according to the third invention, a higher-resolution screen image is displayed in full screen on a high-resolution external display device without using a display device with a multiscan function, by selecting a suitable display device with a resolution corresponding to a previously fixed resolution from candidates of commonly used display devices such as a PC display device and a TV monitor, and by using it as the high-resolution external display device. And especially according to the fourth invention, a higher-resolution screen image is displayed in full screen on a high-resolution external display device, by using a suitable commonly used display such as a PC display device and a TV monitor as the high-resolution external display device and by selecting and assigning the screen's resolution of a high-resolution external display device by a resolution designating means.
Note that in the case a high-performance external display device with a multiscan function is used as a high-resolution external display device, a screen image with the designated resolution can be displayed in full screen on the screen of the high-performance external display device, only if the designated resolution is lower than the screen's resolution of the high-performance external display, even if the designated resolution is not equal to the screen's resolution of the high-performance external display.
And especially to the fourteenth or fifteenth invention, a display device with a commonly used type of interface means is adopted as a high-resolution external display device. Especially according to the fourteenth invention, since signal conversion of “digital (bit-mapped data)->analog->digital” becomes dispensable in the case a digital display device such as a liquid crystal display device is used as a high-resolution external display device, image degradation due to a signal conversion can be avoided. On the other hand, according to the fifteenth invention, a TV monitor and a commonly used PC display device with an analog RGB interface, such as VGA connector or so on, can be used as a high-resolution external display device.
According to the sixteenth invention of a mobile information communication apparatus, when a higher-resolution image is displayed on a screen of a high-resolution external display device connected to an interface means A1 of a mobile information communication apparatus, a built-in battery of the mobile information communication apparatus can be charged by being supplied with electrical power, via a charge terminal A, from the high-resolution external display device, a connection unit connecting said interface means A1 and the high-resolution external display device, an external input/output unit unifying a connection unit and external display devices, or so on.
According to any one of the seventeenth to the nineteenth invention of a mobile information communication apparatus, not only a higher-resolution image can be displayed on a screen of a screen of a high-resolution external display device connected to an interface means A1 of a mobile information communication apparatus, but also data can be inputted with a full keyboard by connecting a full keyboard to an interface means A2 of the mobile information communication apparatus.
Hereinbefore and hereinafter, “full size keyboard such as Japanese 106 keyboard and Japanese 109 keyboard, which are of JIS (Japanese Industrial Standard) key arrangement” is referred as “full keyboard”.
In the first place, in a mobile telephone unit and other mobile information communication apparatuses, character input operations by using its own attached operation keys, such as editing of an e-mail, an entry of URL of a web site, character input to an entry form in a web page, and editing of addresses in a telephone directory, are increased. Despite this, operationality of character input is bad in a mobile information communication apparatus, because its own attached operation keys are smaller than those of a full keyboard and a center distance between neighboring keys is also smaller due to a constraint of portability. Especially, in the case of a mobile telephone unit, since operation keys are restricted to a few keys composed of numeric keys and several function keys, in order to input, for example, the fifth character of the Japanese syllabary, such operations as to push a certain numeric key (normally key of “1”), which is assigned to first line of the Japanese syllabary (“kana”), five times after changing an input mode to Japanese input mode by using function keys. Therefore, it is very stressful for a user to input a number of characters, in such a case of editing a long e-mail.
In contrast, according to any one of the seventeenth to nineteenth invention of a mobile information communication apparatus, a problem of a constraint in data input, as well as a screen constraint due to its portability, is reduced or is solved. In fact, only by connecting an external display device, such as a commonly used PC display device to an interface means A1, and connecting an external input device such as a full keyboard to an interface A2, almost the same operationability as that in the conventional case that both of a mobile information communication apparatus and a PC are used, as far as such operations as editing, sending and receiving of e-mail, browsing of a web page, a bi-directional communication using the Internet or so on.
On the other hand, according to any one of the seventeenth to nineteenth invention of a mobile information communication apparatus, it sometimes more convenient to connect the invented mobile information communication apparatus to an external display device and an external input device, than that both a conventional mobile information communication apparatus and a PC are used as described below:
A user, who possesses a PC along with a conventional mobile information communication apparatus, is usually required to have two e-mail addresses, one of which is of a mobile information communication apparatus and the other of which is of a PC, and is also required to check delivery status of e-mails of both of a mobile information communication apparatus and a PC. Some Internet service provider provide services that an e-mail sent to one and the same address can be received by both of a mobile information communication apparatus and a PC. In this case, however, such an inconvenience, that an e-mail received by a PC is not recorded in a receiving history in a mobile information communication apparatus and vice versa, occurs, since mailer software of the mobile information communication apparatus is different from that of the PC. And an extra effort is required to edit both an address list in a mobile information communication apparatus and that in a PC.
Moreover, when, for example, a use comes back to the circumstance, in which he can use a PC, from the situation, in which he is just browsing a web page outside with a mobile information communication apparatus, another extra effort is required to start up a PC and reentry URL of the web page, although the mobile information communication apparatus has already been connected to the web site. Also, when a use comes back to the circumstance, in which he can use a PC, from the situation, in which he is just inputting e-mail text outside by operating operation keys of a mobile information communication apparatus, it is required to start up a PC and start to input text from its beginning. Thus, it is impossible to move smoothly from a work on a mobile information communication apparatus to that on a PC, and there is a problem that it takes longer to start up a PC than to start up a mobile telephone unit.
In contrast, according to any one of the seventeenth to the nineteenth invention of a mobile information communication apparatus, in the case that the invented mobile information communication apparatus is used in connection with an external display device and an external input device, data is processed consistently by a data processing means belonging to the mobile information communication apparatus, and necessary information, such as an e-mail address or so on, is stored in a storage means such as a flash, which belongs to the mobile information communication apparatus. Herewith, even when a user comes back home or to a office from outside, he can smoothly continue his work, only by connecting the mobile information communication apparatus with an external display device and an external input device. Also it is not necessary to duplicates to manage data, as in the case both a mobile information communication apparatus and a PC is used.
Moreover, according to any one of the invention of the seventeenth and nineteenth invention of a mobile information communication apparatus, the effect to reduce wasteful use of resources is expected.
Function of a PC is rapidly upgraded corresponding mainly to version upgrade of OS and CPU and, as a result, a PC is replaced in interval of seven to ten years. On this occasion, it is usual to dispose of not only a PC package including mother board implemented with a CPU and memories but also a display device, full keyboard and an external storage device such as HDD (Hard Disk Drive).
In contrast, in the case that the invented mobile information communication apparatus is used in connection with an external display device and an external input device, since, in the first place, the mobile information communication apparatus is usable by itself, it is only necessary to replace the mobile information communication apparatus with the remainder being used as before, even when a CPU and other data processing means is revised to a higher-performance and former ones become obsolete. As a result, such a mass disposal caused by replacement as in the case of a PC does not occur.
According to the twentieth or the twenty-first invention of a mobile information communication apparatus, a data processing means belonging to the mobile information communication apparatus can write data to or read out data from an external storage device, by connecting the external storage device to an interface means A3 of the mobile information communication apparatus. Herewith, contents, such as images downloaded from a web site, moving images recorded from TV broadcast, game programs and so on, and image files imaged by such imaging means as digital camera, digital video recorder and so on, are stored in the external storage device instead of a storage means belonging to the mobile information communication apparatus. And also, by using an external storage device for supplying application programs, such as CD-ROM (Compact Disc Read Only Memory) drive, DVD (Digital Versatile Disc or Digital Video Disc)-ROM drive, or so on, a user can copy application programs, which are stored in CD-ROM, DVD-ROM or so on, to a storage means belonging to the mobile information communication apparatus such as flash memory or so on and he can activates a data processing means by the application programs.
In a conventional mobile telephone unit, indeed, it is possible to copy contents file, such as image files acquired by communication means or imaging means, to a storage device belonging to a PC or so on by using a removable storage media such as a memory card. In this case, however, user must follow the following procedure: Contents files stored in a storage means belonging to a mobile telephone unit is copied to a removable storage media; The removable storage media is removed from the mobile telephone unit and then inserted into a media drive of a PC or so on: The contents files are copied to the storage media such as HDD by activating the HDD belonging to the PC.
In contrast, according to the twentieth or the twenty-first invention of a mobile information communication apparatus, since a data processing means of the mobile information communication apparatus can directly access an external storage device, it is possible to copy files directly from a storage means belonging to the mobile information communication apparatus to an external storage device.
According to any one of the twenty-second to the twenty-third invention of a mobile information communication apparatus, when a web page in web server connected to the Internet is browsed, or contents files such as image files, game programs or so on are acquired from a web server, images corresponding to the web page or contents files can be displayed on a screen of a high-resolution external display device, which is connected to an interface means A1 of the mobile information communication apparatus, in addition on a display panel belonging to the mobile information communication apparatus as before. On this occasion, additionally, a higher-resolution image with a higher resolution than the screen's resolution of the display panel belonging to the mobile information communication apparatus, without any constraint due to screen's resolution of display panel belonging to the mobile information communication apparatus.
Especially according to the twenty-third invention, in association with CGI (Common Gateway Interface) or PHP (Hypertext Preprocessor) function, such an “automatic sorting to a proper web site” function is realized as follows: When a destination assigning means of the invented mobile information communication apparatus assigns an interface means A1 as a destination of plotting command/data, that is, when a higher-resolution image is displayed on a high-resolution external display device, a web site, which, for example, includes web pages with a fixed-width layout of VGA or XGA, is accessed; Otherwise, that is, a image is displayed only on a display panel belonging to the mobile information communication apparatus, a web site, which is composed only by web pages with a liquid layout or fixed-width layout of small horizontal resolution.
According to the twenty-fourth invention of a mobile information communication apparatus, a moving image carried by a wireless moving image signal is displayed in real time on a screen of a high-resolution external display device connected to an interface means A1 of the invented mobile information communication apparatus, in addition on a display panel belonging to the mobile information communication apparatus. On this occasion, additionally, a higher-resolution image with a higher resolution than the screen's resolution of the display panel belonging to the mobile information communication apparatus, without any constraint due to screen's resolution of display panel belonging to the mobile information communication apparatus.
Also, a moving image carried by a wireless moving image signal is recorded and converted to a moving image data file. The moving image data file can be stored in a storage means belonging to the mobile information communication apparatus and is read out and played back later. On this occasion, a moving image can be played back not only on a display panel belonging to the mobile information communication apparatus but also on an external display with a higher resolution.
According to the twenty-fourth invention of a mobile information communication apparatus, a subject is imaged with the invented mobile information communication apparatus and a moving image of the subject is displayed in real time on a screen of a high-resolution external display device connected to an interface means A1 of the invented mobile information communication apparatus, in addition on a display panel belonging to the mobile information communication apparatus. On this occasion, a moving image can be played back not only on a display panel belonging to the mobile information communication apparatus but also on an external display with a higher resolution.
Also, a still image or a moving image, which is imaged by the mobile information communication apparatus, is converted to a data file. And the data file can be stored in a storage means belonging to the mobile information communication apparatus and is read out and played back later. On this occasion, a moving image can be played back not only on a display panel belonging to the mobile information communication apparatus but also on an external display with a higher resolution.
According to any one of the twenty-sixth to the twenty-eighth invention of a mobile information communication apparatus, markup document files and their linked files, which is acquired from a web server, or is stored in a storage means is processed and a page image corresponding to these files is displayed on a screen of a high-resolution external display device connected to an interface means A1 of the mobile information communication apparatus, in addition on a display panel belonging to the mobile information communication apparatus.
Especially, when a user connects to a web site for PC and browses a web page, which is intended to be browsed with a screen of, for example, VGA, by the mobile information communication apparatus, a whole page image is browsed not only on a display panel belonging to the mobile information communication apparatus by horizontally scrolling frequently but also, in a similar layout as a screen image on a PC, on a screen of a high-resolution external display device connected to an interface means A1 of the mobile information communication apparatus without any horizontal scrolling.
According to any one of the twenty-ninth to the thirty-second invention of a mobile information communication apparatus, an intrinsic image of said digital image signal or said image data file can be displayed on a screen of a high-resolution external display device connected to an interface means A1 of the mobile information communication apparatus. Especially, in the case that a resolution of an intrinsic image is higher than a screen's resolution of a display panel belonging to the mobile information communication apparatus, an intrinsic image can be displayed on a screen of a high-resolution external display device, although a whole image with a lower resolution generated by thinning out a part of the signal or the data or a part image.
Especially, according to the thirty-second invention of a mobile information communication apparatus, a map image including its present location information is displayed on a screen of a high-resolution external display device connected to an interface means A1 of the mobile information communication apparatus, in addition on a display panel belonging to the mobile information communication apparatus.
A navigation service using GPS is provided as a service for a mobile telephone unit, and, recently, so-called “NAVI for front-seat passenger” service has come to be provided, that provide with traffic jam information and traffic route information to a destination, in addition to normal navigation information. In the first place, however, a display devise belonging to a mobile telephone unit is so small that it is legally and practically impossible for a driver himself to browse map information because he has to hold a mobile telephone unit in front of his eyes. Therefore, this service is assumed that a front-seat passenger browses map information.
In contrast, according to the thirty-second invention of a mobile information communication apparatus, a driver himself can browse map information with his hand free, by placing a high-resolution external display device with a comparable size as that of a display panel part of a normal car navigation system to a comparable position as that of a normal car navigation system.
According to any one of the thirty-third to the thirty-sixth invention of a connection unit applied to a mobile information communication apparatus, by connecting a mobile information communication apparatus and a high-resolution external display device via the invented connection unit, the following merits can be gained, compared with the case of a direct connection of a mobile information communication apparatus and a high-resolution external display device.
Firstly, in a mobile information communication apparatus, a terminal part comprising an interface means A1 must be designed to be small and specially different from that which is commonly used for a PC and so on, because its portability is valued. By this reason, connection cable connected to the terminal part is also so special that it is difficult to prepare a variety of cables with different length, and, therefore, the positional relation between a mobile information communication apparatus and a high-resolution external display device positional relationship is naturally subjected to a restraint, if they are connected with each other directly by a connection cable.
In contrast, in the case that they are connected with each other via the invented connection unit, a mobile information communication apparatus and a high-resolution external display device are connected with each other comparatively freely by connecting an interface means A1, an interface means B1 and a high-resolution external display device as follows: An interface means A1 and an interface means B1 are connected with each other by a special cable; An interface means B2 and a high-resolution external display device are connected with each other by a commonly used cable, by making a terminal of an interface means B2 a commonly used terminal conforming a high-resolution external display device. As a result, a mobile information communication apparatus and a high-resolution external display device are placed in a free positional relation.
A mobile information communication apparatus and a high-resolution external display device are, indeed, connected not only by a connection cable but also by a wireless connection means. In such a case, however, securer communication, which can avoid the problem of approach range and obstacle of wireless communication, is realized by using the invented connection unit in as follows: An interface means A1 and an interface means B1 are connected with each other by wired connection means; An interface means B2 and a high-resolution external display device are connected with each other by wireless connection means. And vice versa is also possible.
Secondly, in the case that a mobile information communication apparatus is connected with an external input device, such as full keyboard, and/or an external storage device, such as HDD, in addition with a high-resolution external display device, a connection of a mobile information communication apparatus and an external devices can be simplified by using the invented connection unit as follows: At the side of a mobile information communication apparatus, a terminal comprising an interface means A1, a terminal comprising an interface means A2, and/or a terminal comprising an interface means A3 are unified; At the side of the invented connection unit, a terminal comprising an interface means B1, a terminal comprising an interface means B2, and/or a terminal comprising an interface means B3 are unified; Both of unified terminals are connected with each other.
And in this case, the invented connection unit connected with a mobile information communication apparatus is used in a similar image as using a desktop PC, by improving a connection between the mobile information communication apparatus and the connection unit in such a manner as follows: An external storage device such as HDD and DC power supply means such as AC/DC circuit, battery and so on is installed in a chassis comprising the invented connection unit; The chassis is also equipped with an insert slot, to which a mobile information communication apparatus is inserted to result in a connection of a terminal part of a mobile information communication apparatus and that of the invented connection unit by direct touch.
Note that the invented connection unit applied to a mobile information communication apparatus only takes only a role of an interface between a mobile information communication apparatus and external devices, and is not equipped with its own display data generating means to generate display data, separately from a data processing means belonging to a mobile information communication apparatus as the first type conventional technology described in “Background Art”. Therefore, the problem of “irrational overlapping investment” and “inefficient resource use, which occurs in conventional technologies, does not occur.
According to anyone of the thirty-eighth to the forty-fourth invention of an external input/output unit applied to a mobile information communication apparatus, by connecting and using the invented external input/output unit with a mobile information communication, the following merits can be gained, compared with the case that a mobile information communication apparatus and a high-resolution external display are connected with each other directly or via a connection unit.
Firstly, a connection of a mobile information communication apparatus and external devices can be simplified, because an interface means to a mobile information communication apparatus, an external display means and an external means such as a keyboard, and even an external storage means such as HDD are unified in to a chassis. A connection of a mobile information communication apparatus and both an external display means and an external input means can be simplified, especially in the following manner: At the side of a mobile information communication apparatus, a terminal comprising an interface means A1, a terminal comprising an interface means A2, and/or a terminal comprising an interface means A3 are unified; At the side of the invented external input/output unit, a terminal comprising an interface means D1, a terminal comprising an interface means D2, and/or a terminal comprising an interface means D3 are unified; Both of unified terminals are connected with each other.
And in this case, the invented external input/output unit connected with a mobile information communication apparatus is used in a similar image as using a notebook PC, by installing an external storage device such as HDD and a battery inside of a chassis comprising the invented external input/output unit and connecting the battery with an AC/DC circuit and commercial power supply plug.
Note that a mobile information communication apparatus and the invented external input/output unit are connected with each other by a special cable to results in a restraint in positional relationship because of the reason described in the description related to a connection unit applied to a mobile information communication apparatus. It is not serious problem, however, since mobile information communication apparatus and the invented external input/output unit are originally assumed to be used comparatively in a neighborhood because of notebook PC-like usage.
Especially according to the forty-first or the forty-fourth invention, a external input/output unit is made into a compact structure, since an external input means are installed in a external display panel belonging to an external input/output unit, and/or, in a frame part a external display panel. Therefore, it is convenient that a mobile information communication apparatus according to any one of seventeenth to the twenty-first invention and an external input/output unit according to the forty-first or the forty-fourth invention are combined and the combination is used as a car navigation system.
Note that in the case the combination of a mobile information communication apparatus according to any one of seventeenth to the twenty-first invention and a an external input/output unit according to the forty-first or the forty-fourth invention is used as a car navigation system, it is possible to construct car-mounted hands-free telephone call system can be constructed in the following manner: A mobile telephone unit with a telephone call function is used as a mobile information communication apparatus; An external input/output unit is equipped with an external speaker and an external microphone; A function to exchange sound data is added to an interface between a mobile information communication apparatus and an external input/output unit.
Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not restricted to the following embodiments and many variations are possible within the spirit and scope of the present invention.
Embodiment 1
In this embodiment, a mobile telephone unit 1 can be used by itself for telephone call, data communication and processing, TV program watching or subject imaging, and various images are displayed on an LCD (Liquid Crystal Display) panel 15, which is a display panel belonging to the mobile telephone unit 1. Hereinafter, it is assumed that screen's resolution of the LCD panel 15A is vertically long QVGA (horizontal×vertical=240×320 pixels) in usual use, but another screen's resolution is possible.
Firstly, when the mobile telephone unit 1 is used for telephone call, a sound picked up by microphone by a microphone 18A is converted to a digital signal by a CODEC (COder-DECoder) 18C and the digital signal goes through a baseband processor 11 and an RF (Radio Frequency) sending/receiving part 111B and is sent to public network as a wireless signal from a communication antenna 111A. In reverse, a wireless signal from public network is received by the communication antenna 111A and is converted to a digital signal by going through the RF sending/receiving part 111B and the baseband processor 11. The digital signal is converted to an analog electrical signal and is finally is outputted as sound from a speaker 18B.
Secondly, when the mobile telephone unit 1 is used for data communication and processing, data, which is inputted by operating a key operating part 16A composed of around twenty small keys and is converted to a digital signal by a key input controller 16B, and/or data, which is included in an wireless signal conforming to the Internet Protocol and received from public network, goes through the RF sending/receiving part 111B and the baseband processor 11 and is converted to the digital signal, are sent to a central processing circuit 1_10A1 via a bus 19. And then the central processing circuit 1_10A1 makes necessary processes on the data and sends the processed data to a RAM (Random Access Memory) 14B, a graphic controller 1_10B and the baseband processor 11 via the bus 19.
Note that sending and receiving of an wireless signal conforming to the Internet Protocol is realized by communicating with a base station of cellular network in the form such as CDMA (Code Division Multiple Access) or by communicating with a base station or an access point of wireless LAN in the form such as DSSS (Direct Sequence Spread Spectrum) and OFDM (Orthogonal Frequency Division Multiplexing).
Especially, when the mobile telephone unit 1 is connected to the Internet and a web page with a liquid layout or a narrow fixed-width layout including that belonging to “mobile site” is browsed, the central processing circuit 1_10A1 acquires markup document files and their linked files comprising the web page via the communication antenna 111A, the RF sending/receiving part 111B, the baseband processor 11 and the bus 19, according to browsing programs stored in a flash memory 14A. And said files are rendered into a page image, of which the number of horizontal pixels is equal to the screen's horizontal resolution of the LCD panel 15A (240 pixels), by the central processing circuit 1_10A1 and the central processing circuit 1_10A1 sends a plotting command of the rendered page image to the graphic controller 1_10B.
The graphic controller 1_10B generates bit-mapped data on a virtual screen, which is created so as to have a high enough resolution, and writes said data in a VRAM (Video RAM) 1_10C.
Hereinafter, the resolution of the virtual screen is assumed to be QUXGA Wide (Quad Ultra XGA Wide) (horizontal×vertical=3840×2400 pixels).
And then the graphic controller 1_10B cuts out a portion of the bit-mapped data describing an image which is displayed on the LCD panel 15A, and send the portion to an LCD driver 15B. Especially, in the case that the number of vertical pixels is larger than the screen's vertical resolution of the LCD panel 15A (320 pixels), the portion of the bit-mapped data moves on the virtual screen according to an operation of the key operating part 16A and a page image is scrolled.
The LCD driver 15B activates each pixel comprising the screen of the LCD panel 15A by activating a source driver part and a gate driver part according to the bit-mapped data and displays page image, in which menu bars are also displayed on the top and/or the bottom, corresponding to said web page.
When the mobile telephone unit 1 is used for TV program watching, a TV signal received by a television receiving antenna 112A is converted to a digital image signal by a television tuner 112B and an AD/DA converting part 1_112C, and the digital image signal is sent to the central processing circuit 1_10A1 via the bus 19.
On the other hand, in the mobile telephone unit 1, it is selectable by operating the key operating part 16A whether a TV broadcast image is displayed in the vertically long configuration or in the horizontally long configuration.
Note that screen's resolution is horizontal×vertical=240×320 pixels in the vertically long configuration and horizontal×vertical=320×240 pixels in the horizontally long configuration.
The central processing circuit 1_10A1 generates a plotting command to generate a bit-mapped data of a screen image displayed on the LCD panel 15A according to said direction selection signal and said digital image signal and the plotting command to the graphic controller 1_10B.
Note that there can be nothing to be displayed at the top and/or the bottom of the screen in the vertically long configuration.
Since, in this case, horizontal and vertical resolution of an intrinsic image of TV broadcast are larger than those of the LCD panel 15A both in the vertically long configuration and in the horizontally long configuration, the central processing circuit 1_10A1 generates a plotting command of a whole image with an lower resolution than an intrinsic resolution by thinning out a part of the digital image signal sent from the AD/DA converting part 1_112C.
The graphic controller 1_10B, the VRAM 1_10C and LCD driver 15A move in the same manner as in the that case a page image of a web page is displayed, except that there is no screen scrolling according to the operation of the key operating part 16A, and, as a result, a moving image of TV broadcast is displayed on the LCD panel 15A in real time.
When the mobile telephone unit 1 is used for subject imaging, reflected or emitted light signal from a subject goes to a CCD 12B through an optical system part 12A including optical lens and is received and converted to an electrical signal of each pixel by the CCD 12B. The electrical signal is converted to a digital image signal by an AD/DA converting part 2_12C and then the digital image signal is sent to the central processing circuit 1_10A1 via the bus 19. Hereinafter, it is assumed that a resolution of the CCD 12B is UXGA (Ultra XGA) (horizontal×vertical=1600×1200 pixels), but another resolution is possible.
On the other hand, the central processing circuit 1_10A1, the graphic controller 1_10B, the VRAM 1_10C and LCD driver 15A move in the same manner as in the that TV program is watched and, as a result, a moving image of the subject is displayed in real time on the LCD panel 15A. Since, in this case, a horizontal and vertical resolution of an intrinsic image imaged by the CCD 12B are larger than those of the LCD panel 15A both in the vertically long configuration and in the horizontally long configuration, the central processing circuit 1_10A1 generates a plotting command of a whole image with an lower resolution than an intrinsic resolution by thinning out a part of the digital image signal sent from the AD/DA converting part 2_12C.
On the other hand, in the mobile telephone unit 1, by operating the key operating part 16A, a bit-mapped data, which is generated cooperatively by the central processing circuit 1_10A1 and the graphic controller 1_10B, can be stored as an image data file in the flash memory 14A. At that time, the bit-mapped data is stored in MPEG (Moving Picture Experts Group) format (including MPEG-1, MPEG-2, MPEG-4) in the case of moving image, and is stored in such format as BMP, TIFF, JPEG, GIF and PNG. Note that an image file is also generated and stored in the case that the central processing circuit 1_10A1 receives and make necessary processes on a digital signal, which is received via the communication antenna 111A, the RF sending/receiving part 111B and the baseband processor 11 by accessing a web site.
The central processing circuit 1_10A1 can access the image data stored in the flash memory 14A via the bus 19. And when the central processing circuit 1_10A1 processes the read out data properly and the graphic controller 1_10B, the VRAM 1_10C and LCD driver 15A move in the same manner as described above, the corresponding image is also displayed on the LCD panel 15A.
Hereinbefore, described is the outline of the function of the mobile telephone unit 1 when it is used by itself. In addition to use by itself, the mobile telephone unit 1 and a connection unit 3 can be made work as an unified information communication system by connecting an external connection terminal part A_13D, which is belong to the mobile telephone unit 1 to connect itself to the connection unit 3, and external connection terminal B_33D comprising an interface part B 33, which is belong to the connection unit 3 via a connection cable 2.
On the other hand, the connection unit 3 is equipped with an interface part C1_35 and interface part C2_36, both of which are interface means to connect external apparatuses. An the external display device 5, which is LCD, is connected to the interface part C1_35, and an external keyboard 61, which is a full keyboard, and a mouse 62 is connected to an interface part C2_36, respectively. Also, the connection unit 3 is equipped with an HDD 34 and a battery B_37A, both of which are connected to interface part B. The battery B_37A is connected with an AC/DC circuit 37B and a commercial power supply plug 37C and the connection unit 3 is made to work by DC power which is once stored in the battery B 37A via them. Note that DC power supply, which is stored in the battery B 37A belonging to the connection unit 3, is also supplied to and stored in a built-in battery 17 belonging to telephone unit 1 via an external connection terminal part B_33D and the external connection terminal part A 13D, and the mobile telephone unit 1 is made to work by the DC power.
Hereinafter, it is assumed that a screen's resolution of the external display device 5 (LCD) is VGA (horizontal×vertical=640×480 pixels) in principle, but another resolution is possible.
When the mobile telephone unit 1 in work and the connection unit 3 are connected with each other, or when the mobile telephone unit 1 in work and the connection unit 3 are connected with each other, and then the connection unit 3 is made to work, or when the mobile telephone unit 1 and the connection unit 3 in work are connected with each other, and then the mobile telephone unit 1 is made to work, the central processing circuit 1_10A1 of the mobile telephone unit 1 receives a connection detection signal of the connection unit 3 from the connection unit 3 and screen's resolution data of the external display device 5 via the external connection terminal part B 33D, the external connection terminal part A 13D and the bus 19.
Hereinbefore and hereinafter, “signal which detects one to be connected” is referred as “one's connection detection signal”.
When the central processing circuit 1_10A1 of the mobile telephone unit 1 detects said connection detection signal, the central processing circuit 1_10A1 generates a plotting command of an image with a higher resolution and send it to the graphic controller 1_10B, instead of a plotting command of an image of which horizontal resolution or resolution is the same as the screen's horizontal resolution or the screen's resolution of the LCD panel 15A.
More concretely, when a web page for PC is browsed with the mobile telephone unit 1, the central processing circuit 1_10A1 generates and sends a plotting command manner corresponding to layout of the web page, according to browser software stored in the flash memory 14A, in the following manner: When the web page is with a liquid layout or a fixed-width layout narrower than screen's horizontal resolution of the external display device 5 (480 pixels), the central processing circuit 1_10A1 generates and sends a plotting command of a page image with the same horizontal resolution as the screen's horizontal resolution of the external display device 5. And when the web page is with a fixed-width layout wider than screen's horizontal resolution of the external display device 5 (480 pixels), the central processing circuit 1_10A1 generates and sends a plotting command of a page image with the same horizontal resolution as the fixed-width.
On the other hand, when TV broadcast is watched or a subject is imaged with the mobile telephone unit 1, the central processing circuit 1_10A1 generates and sends a plotting command of a whole image corresponding to the screen's resolution of the external display device 5 by thinning out a part of the digital image signal.
And the central processing circuit 1_10A1 generates a sending command to send bit-mapped data cut out from the VRAM 1_10C to a TMDS transmitter 13A instead to the LCD driver 15B and sends the sending command to the graphic controller 1_10B.
Note that, in the case a web page with fixed-layout is browsed with a connected external display devise such as full high-vision TV monitor (horizontal×vertical=1920×1080 pixels), of which screen's resolution is high enough but lower than the logical resolution of the previously created virtual screen (3840×2400 pixels), the central processing circuit 1_10A1 generates and sends a plotting command of a page image with the same horizontal resolution of the screen's horizontal resolution of the external display device 5, because the width of almost all the web page does not exceed the screen's horizontal resolution of the external display device 5.
Also, in the case TV broadcast is watched or a subject is imaged with a connected external display devise such as full high-vision TV monitor, the central processing circuit 1_10A1 generates and sends a plotting command of an intrinsic image of a digital image signal, because the resolution of the intrinsic image does not exceed the screen's horizontal resolution of the external display device 5.
The graphic controller 1_10B generates bit-mapped data on the previously created virtual screen and writes it in the VRAM 1_10C according to the plotting command received from the central processing circuit 1_10A1. And then the graphic controller 1_10B cuts out bit-mapped data describing an image displayed on the screen of the external display device 5, of which resolution is the same as the screen's resolution of the external display device 5, from the VRAM 1_10C, according to screen's resolution data of the external display device 5, which is received from the central processing circuit 1_10A1, and sends the bit-mapped data to the TMDS transmitter 13A. The TMDS transmitter 13A sends the bit-mapped data to the interface part B 33 of the connection unit 3 via the external connection terminal part A 13D in TMDS format.
In the connection unit 3, the interface part C1_35 with TMDS receiver function receives, makes necessary processes on the bit-mapped data and sends it to the external display device 5, and an image with a resolution corresponding to the screen's resolution is displayed on the screen of the external display device 5 as a result. On this occasion, horizontal whole of a page image is displayed without any horizontal scrolling in the case that a web page with a liquid layout or a fixed-width layout narrower than the screen's horizontal resolution of the external display device 5 is browsed. In the case, however, that a web page with a fixed-width layout wider than the screen's horizontal resolution of the external display device 5 is browsed, only a horizontal portion of page image is displayed on the screen of the external display device 5 and a whole image can be browsed by horizontal scrolling. On the other hand, in the case TV broadcast is watched or a subject is imaged, an image with a lower resolution than the intrinsic image of the digital image signal is displayed in full screen on the screen of the external display device 5.
Note that in the case such a high-resolution display device as a full high-vision TV monitor is selected as the external display device 5 and a web page is browsed with the external display device 5 connected, a horizontal whole of a page image is browsed without any horizontal scrolling in almost all the cases because of the reason described above.
On the other hand, also, when TV broadcast is watched or a subject is imaged with the external display device 5, which is a high-resolution display device as a full high-vision TV monitor, an intrinsic image is displayed, corresponding that the central processing circuit 1_10A1 generates and sends a plotting command of an intrinsic image of a digital image signal. Especially, in the case that the external display device 5 or the interface part C1_35 of the connection unit 3 has an upscan function, the intrinsic image is displayed in full screen on the screen of the external display device 5. Especially, in the case that the upscan function accompanies a pixel interpolation function, a fine screen image with the same resolution as the screen's resolution of the external display device 5.
When the central processing circuit 1_10A1 of the mobile telephone unit 1 receives said connection detection signal, the central processing circuit 1_10A1 send a source assigning signal to the key input controller 16B, which commands it not to receive an input signal from the key operating part 16A of the central processing circuit 1_10A1 and to receive an input signal from the external keyboard 61 connected to the interface part C2_36 of the connection unit 3. Owing to this function, a user can input data by operating the external keyboard 61, which is a full keyboard, instead by operating the key operating part 16A of the mobile telephone unit 1, of which operationality of character input is bad.
And the central processing circuit 1_10A1 of the mobile telephone unit 1 can read out a data file stored in the flash memory 14A according to a key operation of keyboard 61 and can store it in the HDD 34 via the bus 19, the external connection terminal part A 13D, and the interface part B 33 of the connection unit 3.
Note that a destination of bit-mapped data generated by the graphic controller 1_10B and a input source of data sent to the central processing circuit 1_10A1 can be assigned or changed, for example, by manually operating the key operating part 16A of the mobile telephone unit 1 as well as automatically assigned or changed according to a connection detection signal received by the central processing circuit 1_10A1. And a resolution of an image described by a bit-mapped data sent to the external display device 5 can be assigned, for example, by manually selecting the resolution conforming to the screen's resolution of the external display device 5 from the choice list of resolutions, of which image is displayed on the LCD panel 15A or on the screen of the external display device 5 as well as automatically assigned according to screen's resolution data of the external display device 5 which is received by the central processing circuit 1_10A1. Also a resolution of an image described by a bit-mapped data sent to the external display device 5 can be fixed, for example, to VGA with no choice.

On the other hand,
When an information communication system composed of the mobile telephone unit 1, the connection unit 3, the external display device 5 and external input devices (the external keyboard 61 and the mouse 62) accesses a web server 91 connected to the Internet 9, the central processing circuit 1_10A1 sends user-agent information to the web server 91 via the bus 19, the baseband processor 11, the RF sending/receiving part 111B and the communication antenna 111A, according to browser software stored in the flash memory 14A. Note that components installed inside of the mobile telephone unit 1 are not sown in
On this occasion, the central processing circuit 1_10A1 makes the user-agent information include information, which specifies whether the central processing circuit 1_10A1 commands the graphic controller 1_10B to send bit-mapped data cut out from the VRAM 1_10C to the LCD driver 15B or to the TMDS transmitter 13A.
The web server 91 stores both “a set of data files for mobile” and “a set of data files for PC”.

Herewith, the central processing circuit 1_10A1 can generate and send a plotting command of a web page with a frame layout.
On the other hand,
When markup document file with a liquid layout either with the LCD panel 15A of the mobile telephone unit 1, of which screen's resolution is assumed to be QVGA, or with an external display device, of which screen's resolution is assumed to be VGA, no horizontal scrolling is required because text automatically moves to next line corresponding to a screen's horizontal width. However, as shown in
