By the way, since a portable telephone is miniaturized and lightened so as to fit in a breast pocket, its display size is smaller than that of a desktop personal computer. Very small. For this reason, in order to utilize it as a device for displaying information, it has been the best to display characters, simple figures, simple photos, or moving images with low resolution.

As described above, since the size of the appearance of the portable telephone and other portable information terminals is limited, the portable telephone and the other portable information terminal have to have a display smaller than the size. For this reason, a desktop personal computer can access various homepages using a large screen and freely display images, while a simple personal computer prepared in advance for a portable information terminal such as a portable telephone. There is a problem that only a homepage having an image configuration can be accessed.

Also, when displaying text information, it is necessary to frequently scroll the screen or switch pages when displaying the contents of an e-mail or a long sentence because the display range is narrow. It was difficult to grasp the contents. In addition, if not displayed in small characters, the number of characters and symbols to be displayed at one time is small, so that these characters and symbols are displayed in small or low quality, and there is a problem that it is difficult to read and is easily fatigued.

However, depending on the device, a key group 105 for various operations may be additionally arranged in this portion. Further, it is possible to arrange the liquid crystal display as a normal size on the front side. In this case, the liquid crystal display 103 shown in FIG. 1 for displaying simple data such as a telephone number may be omitted.

FIG. 2 shows a state where the display unit of the portable information terminal is opened. When the display unit 104 is opened, a first liquid crystal display 111 is disposed on the door side inside the display unit 104, and the second liquid crystal display 1 is disposed on the apparatus body side.
12 are arranged. Therefore, by using these liquid crystal displays 111 and 112 as one screen, it is possible to display information such as characters and images on a substantially large screen.

FIG. 3 shows an Internet homepage (URL: uniform) using the portable information terminal of this embodiment.
This is an outline of an information processing system for accessing resource locators. Each of the portable information terminals 100 ₁ ,..., 100 _N is a corresponding base station 12.

By receiving and displaying the binary data via the P server 122, the burden of image processing is reduced.

In the conventional portable telephone, the size of the display is small, so that the
From 5 onwards, data is downloaded to the small screen server 124 from a home page mainly written with characters and described exclusively for mobile phones. Then, this is directly converted into binary data for displaying the information for each screen and transmitted to the corresponding _{one of} the base stations 121 ₁ ,..., 121 _M.

In this embodiment, the small screen server 1 is also used in this method.

The base station 121 ₁ and generically sent to the WAP server 122 here, and to transmit to a corresponding one of the ...... 121 _M. The large screen server 123 downloads a homepage of exactly the same type as that accessed by the personal computer 126, and downloads it to the WAP server 1.
22. WAP server 122,
The large-screen server 123 and the small-screen server 124 each include a CPU (Central Processing Unit) (not shown), and perform predetermined control operations using a control program stored in a storage medium (not shown). It is supposed to do.

FIG. 4 shows a main part of control of the WAP server of this embodiment when any portable information terminal accesses a homepage. When any _{one of the} portable information terminals 100 ₁ ,..., 100 _N shown in FIG. 3 specifies a URL to access the home page (step S141: Y), the portable information of the request destination is received. It is determined whether the terminal 100 is in the large screen mode or in the other small screen mode (step S14).
2). Here, the large screen mode is a mode in which the image is displayed on the display unit 104 larger than the conventional display as shown in FIG. That is, the portable information terminal 1 of the present embodiment
When 00 requests display of a homepage, the WAP server 122 determines that processing in the large screen mode is requested. On the other hand, when a homepage is accessed from a mobile phone (not shown) displayed on a conventional small one-screen display, it is determined that the mode is the small screen mode. When a portable information terminal capable of switching between a large screen and a small screen is used, the mode differs depending on which size the image is displayed.

FIG. 5 shows a state of data processing in a portable information terminal capable of switching between a large screen and a small screen. If the mode is the large screen mode for displaying a large screen (step S161: Y), data is acquired using the large screen server 123 and displayed on a large screen display (step S162). For example, when the first liquid crystal display 111 and the second liquid crystal display 112 shown in FIG. 2 constitute a large screen, for example, the same image information is divided into two and displayed. Since the screen to be displayed is large as a whole, more text information can be displayed, and image data or a combination of other data can also be displayed. In order to divide one image into two and display it, for example, image data displayed in a bit map memory for one page is divided into two regions and read, or one image is stored in two bit map memories.
A conventional method such as reading and reading while dividing the line in half may be used.

If it is determined in step S161 that the mode is not the large-screen mode but the small-screen mode (N), data is obtained using the small-screen server 124, and the small-screen display is displayed. Is displayed (step S163). On the small screen display, a small image as a whole centering on characters and symbols can be displayed.

Returning to FIG. 4, the description will be continued. If it is determined that the mode is the large screen mode (step S142:
Y), using the large screen server 123 to access the homepage used by the ordinary personal computer 126, receive the data from the large screen server 123, compile it, convert it to binary data, It will be transmitted to the portable information terminal 100 (step S143). In the case of the small-screen mode (step S142: N), using a small-screen server 124, a so-called mobile homepage is accessed to receive the data, and the data is compiled and converted into binary data. To each portable information terminal 100 (step S144).

The first liquid crystal display 11 like the display of the portable information terminal 100 of the present embodiment.
If there is a gap that cannot be displayed adjacent to the first and second liquid crystal displays 112, the production side and the display side of the home page are divided into two screens in advance (that is, as if two screens are continuous). In some cases, it is preferable to perform the processing of the image information on the assumption that the display form does not substantially constitute one screen). For example, when there is a plurality of image data in one page, these are displayed on the first liquid crystal display 1.
The processing is such that the display is shifted to one side so as not to straddle the boundary between the second liquid crystal display 112 and the second liquid crystal display 112. In this sense, the image may be divided into two and displayed, or may be divided into two and displayed. Two liquid crystal displays 111, 11 on the homepage production side
In step 2, the device may be devised so as not to cause a problem in display, or the WAP server 122 may perform processing such as shifting the image. If the data cannot be handled by the WAP server 122, the Internet network 125
At the stage of accessing the personal computer 126
It is also possible to prepare data for a large screen for a plurality of displays other than the normal description format that is obtained by and obtain it.

FIG. 6 shows a main part of the control of the WAP server capable of switching between a screen division mode as a mode for dividing and displaying two screens in advance and another display mode. The WAP server 122 of this example determines whether or not the portable information terminal 100 has requested display in the screen division mode (step S181). Divide into two screens by accessing the homepage or by moving the display position of the image consisting of bitmap images etc. in the data of the homepage. Binary data for each screen is divided. It is created and transmitted to the portable information terminal 100 (step S182). Therefore, the portable information terminal 100 only needs to display the divided binary data on the corresponding displays. When the display in the screen division mode is not requested, the binary data of one screen is transmitted (step S183). If the portable information terminal 100 that has received this has one display, this is displayed as it is.

The WAP server 122 described with reference to FIG.
It is possible for the portable information terminal 100 to directly perform the screen dividing process performed by the portable information terminal 100 as described above as long as the process simply displays the screen divided into two. In this embodiment, the server is set to the WAP server 12 so that the description can be better understood.
2. Large screen server 123 and small screen server 124
Although the description has been given with reference to the example in which the three types are divided, it is of course possible to configure these as the same server.

First Modified Example

FIG. 7 shows a first modification of the portable information terminal of the present invention. The portable information terminal 200 of the first modified example has a folding structure that can be opened and closed right and left by a hinge mechanism 201. As shown, the first liquid crystal display 211 and the second liquid crystal display 212 are arranged close to each other in an open state, and various information can be displayed on a large screen by using them. In this modified example, a normal key group 202 is arranged below the first liquid crystal display 211, and a pointing device for inputting position information by tilting the finger in each direction below the second liquid crystal display 212 is provided. A device 203 and a pointing device 204 for inputting positional information by pressing the pad with a finger or the like are arranged.
The operability of images and the like has been improved in combination with the operability control 05. Therefore, even if one piece of image information is divided into two and the boundary portion is difficult to see, the state of the image at the boundary portion can be grasped by a method such as scrolling the image left and right.

In this modification, the portable information terminal 20
In the state where 0 is closed, the surface on which these are arranged is slightly depressed so that the key group 202, the pointing device 203 and the like do not collide.

Second Modification

FIG. 8 shows a second modification of the portable information terminal of the present invention. The portable information terminal 300 of the second modified example has two hinge mechanisms 301 and 302.
Is used so that it can be folded in a Z-shape, and is usually used in a folded state using a relatively small liquid crystal display 304 for display. At this time, the operation keys 305 are used for operation.

FIG. 9 shows a state where the portable information terminal is opened. When the portable information terminal 300 is opened on the same plane, the first liquid crystal display 311 and the second liquid crystal display 312 are arranged close to each other while the operation keys 305 can be operated. Therefore, various information can be displayed on a large screen by using them.

Of course, in the second modification, it is possible to make the liquid crystal displays of the three surfaces the same size. In this case, the simple information 1
If a large screen is required when viewed on a single liquid crystal display, the portable information terminal is expanded to display information on three screens. Further, as in the case of the third modified example described below, for example, left and right images are displayed one by one on displays located at both ends of three liquid crystal displays, and these images are viewed with different eyes so that stereoscopic viewing is possible. Can be performed.

Third Modified Example

FIG. 10 shows a third embodiment of the portable information terminal according to the present invention.
It is a modification of the first embodiment. The portable information terminal 400 of the third modified example has an image display jack 403 on the upper part of a portable information terminal main body 402 having a relatively small display 401 which has been conventionally used. When a terminal of a fixed head type display 404 is connected to the image display jack 403, a relatively large screen image can be visually obtained with a single eye or both eyes through a display unit 405 using a liquid crystal or an optical system. Will be done. When reproducing an image with both eyes, the image is acquired from a homepage for stereoscopic vision, separated into left and right images as necessary, and shared and displayed on two left and right displays. You can see.

In the third modified example, if another display device (not shown) including a large-screen type CRT or a liquid crystal display is connected to the image display jack 403, a large-screen image can be displayed similarly. An Internet home page or the like can be displayed. Portable information terminal body 402
Is to determine whether or not these devices for display are connected to the image display jack 403 to determine whether the mode is the large screen mode described with reference to FIG. 4 and the type of image acquisition is different.

In the third modification, there is no occurrence of a seam between the displayed large-screen images. In particular, the device shown in FIG. 10 can easily acquire large-screen and high-resolution information on the display 404 even when the user is away from home. And WAP
Since the image information for each screen is converted into binary data on the server 122 side and sent to the portable information terminal main body 402, even if, for example, moving image information or information requiring special conversion processing, these are High-speed processing can be performed by taking all of the above processing. Therefore,
Although common to the previous embodiment and other modified examples, it is possible to easily download information such as a plug-in or the like and a high-speed CPU or a circuit for image processing on a large screen with high resolution without requiring a receiving side. Can be obtained. For this reason, depending on the type of information to be acquired and the communication speed environment, the portable information terminal body 402 may be more accessible than accessing the homepage with a personal computer provided at home.
It is possible to obtain image information under better conditions by connecting to a home display or television via the WAP server 122 from.

Fourth Modified Example

FIG. 11 shows a fourth embodiment of the portable information terminal according to the present invention.
It is a modification of the first embodiment. The portable information terminal 500 of the fourth modified example includes a transmissive liquid crystal plate 501 and a light source and an optical system (not shown) for enlarging and displaying an image displayed thereon on a display panel 502. The portable information terminal main body 503 is connected to the power source 505 when displaying an image in an enlarged manner as described above. In this modification, the power supply 505 also serves as the stand of the portable information terminal main body 503.

The portable information terminal 500 of the fourth modified example
Although it is necessary to prepare the power supply 505 except for a display for a short time, an enlarged image can be easily obtained using a familiar place or object such as a wall, a notebook, or white paper. Ideal for presentations, etc.

Although the embodiment has been described with reference to a portable telephone, it is obvious that the present invention can be applied to an entire portable information terminal using a wireless or wired communication line. In the embodiment and the first to third modified examples, a liquid crystal display is used as a display, but a display other than a liquid crystal can be used freely. In addition, it goes without saying that these displays may be capable of displaying colors or may be capable of displaying monochrome images. Further, in the embodiment, the WAP server is used. However, the present invention is not limited to a server using such a special protocol. In short, an intermediate unit for performing image processing for reducing the burden on the portable information terminal side. Any image conversion means may be used.

In the fourth modification, the information appearing on the transmission type liquid crystal or the object is enlarged and displayed. However, the information appearing on the reflection type liquid crystal or the object is enlarged and displayed. It is also possible that the present invention is applied to them. Further, in the fourth modification, the power supply 505 connected to the portable information terminal 500 has been described as a device for simply supplying power. However, an optical magnifying mechanism is prepared in this device, and the display is performed from the portable information terminal 500 side. The image data to be received may be received, and the image enlarged on the wall or the like may be displayed as shown in FIG. In this case, the portable information terminal 500 does not necessarily need to be supplied with power from the outside (there is an advantage of charging the portable information terminal 500 if it is integrated with the charger), and receives the image data to be displayed. That is, it is only necessary to provide a terminal to be used. In this case, the concept is the same as that of the external display of the image in the third modified example shown in FIG.

Each of the displays used in the present embodiment and the modification may be constituted by one component such as a liquid crystal display, or the one described as a single liquid crystal display may be constituted by a plurality of liquid crystal displays or the like. It may be composed of a plurality of parts. It is also possible to reduce the manufacturing cost by reducing the size of each display. Although the display 404 of the third modification is shown as a single-eye display, it may be a binocular display. The display 404 is connected to the image display jack 403 using the image display jack 403.
Although the connection is made by wire, it is obvious that the connection can be made by wireless.

[0050]

As described above, according to the first aspect of the present invention, the portable information terminal has a structure that can be opened and closed or folded, and the display is arranged on two or more surfaces thereof. The information terminal itself can be formed in a compact shape without displaying a large screen. When a large image needs to be displayed, at least two or more of these displays are simultaneously displayed in an expanded state so as to be adjacent to each other, so that the display area of the image is enlarged. Various information can be displayed with a margin. In addition, not only the display surface for the portable information terminal can be enlarged, but also the surface for performing the input operation can be greatly expanded as compared with the related art. Therefore, it can be utilized not only as a telephone but also as a small-sized computer for a wide range of uses as a memo pad, information input and processing device.

According to the second aspect of the present invention, the display unit for displaying the information to be enlarged on the portable information terminal itself, and the display of this display unit is optically enlarged to other parts or optical parts. Since an enlargement means for displaying the image at a typical image display position is provided, an enlarged image can be displayed on another portion such as a wall, and a sufficiently large image can be obtained if optical conditions are satisfied.

According to the invention as set forth in claim 3, large-screen data to be displayed on a relatively large screen is acquired from the Internet network, and this is transmitted to the portable information terminal as binary data, and the plurality of displays are obtained. In such a case, even a portable information terminal having a low processing capability can easily display a relatively large screen including an image or the like or a high-resolution display.

According to the fourth aspect of the present invention, not only small-screen data acquired for a portable information terminal or the like but also large-screen data to be displayed on a relatively large screen as in the prior art. I'm trying to get For this reason, data suitable for the device can be displayed, and not only is it compatible with the existing system, but if one portable information terminal is, for example, a foldable type, small data can be folded. There is an effect that display can be performed in a compact state, and large-scale or complicated display data can be displayed with a sufficient display area with the apparatus spread out on a desk or the like.

According to the fifth aspect of the present invention, in the information processing system according to the third or fourth aspect, the device which receives the data transmitted by the data transmitting means transmits the data for the large screen to the external display unit. I decided to display it. As a result, it is possible to provide a display that looks like a large screen or a display that is actually optically enlarged without having a large screen in the portable information terminal itself. Moreover, the device (portable information terminal)
Processes binary data, so that the processing load can be reduced.
