Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an image data transmission server for transmitting image data to a portable information terminal that can be carried in a relatively small size, such as a portable telephone or a portable computer using a PHS or a modem.
[0002]
[Prior art]
The development of portable information terminals such as portable telephones is remarkable. In particular, portable telephones have made use of their functions as communication terminals to highlight not only the functions of original telephones but also the characteristics of devices that display various types of information using a communication network.
[0003]
[Problems to be solved by the invention]
By the way, the size of the display is very small compared with that of a desktop type personal computer because the portable phone is miniaturized to fit into a breast pocket and light in weight. For this reason, when trying to use it as a device for displaying information, at best it was full of displaying characters, simple figures, simple photos, and videos with low resolution.
[0004]
As described above, since the size of the external appearance of the mobile phone or other mobile information terminal is limited, the mobile phone or other mobile information terminal has only a display having a size smaller than that size. For this reason, a desktop personal computer can access various homepages using a large screen and display images freely. On the other hand, a simple personal computer previously prepared for a portable information terminal such as a portable telephone is available. There was a problem that only the homepage of the image configuration could be accessed.
[0005]
In addition, when displaying text information, it is necessary to frequently scroll the screen or switch pages when displaying the contents of e-mails or long sentences because the display range is narrow. It was difficult. In addition, since the number of characters and symbols to be displayed at a time is small unless they are displayed in small characters, these characters and symbols are displayed in a small or low quality, and there is a problem that they are difficult to read and easily fatigued.
[0006]
SUMMARY OF THE INVENTION An object of the present invention is to provide an image data transmission server for transmitting image data to a portable information terminal, which can enlarge an area of an image to be displayed and relax or eliminate restrictions on display objects. .
[0007]

DETAILED DESCRIPTION OF THE INVENTION
[0018]
【Example】
Hereinafter, the present invention will be described in detail with reference to examples.
[0019]
FIG. 1 shows the appearance of a portable information terminal according to an embodiment of the present invention. The portable information terminal 100 according to the present embodiment is a portable phone, and an antenna 101 and a speaker 102 are arranged on the upper part thereof, and a simple data such as a telephone number is displayed immediately below the speaker 102. A liquid crystal display 103 is arranged. A display unit 104 having a door structure that can be freely opened and closed is disposed under the liquid crystal display 103. A key group 105 and a microphone 106 for various operations such as dial operations are arranged further below the display unit 104. The surface of the display unit 104 is covered with plastic or metal, and no display is performed. However, depending on the apparatus, a key group 105 for various operations may be additionally arranged in this portion. Further, it is possible to arrange the liquid crystal display on the front side as a normal size. In this case, the liquid crystal display 103 shown in FIG. 1 for displaying simple data such as a telephone number may be omitted.
[0020]
FIG. 2 shows a state in which 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, and a second liquid crystal display 112 is disposed on the apparatus main body side. 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.
[0021]
FIG. 3 shows an outline of an information processing system for accessing a homepage (URL: uniform resource locators) on the Internet using the portable information terminal of this embodiment. Each portable information terminal 100 _1, ...... 100 _N, the base station 121 ₁ corresponding respectively, WAP through ...... 121 _M (wireless application protocol) is adapted to be connected to the server 122. WAP server 122, the base station 121 _1, the portable information terminal 100 ₁ via a corresponding one of the ...... 121 _M, against those accessing a predetermined website Internet among ...... 100 _N 1 is a server having a function of transmitting binary data for each screen. Here, the binary data does not necessarily mean bitmap data, and any data such as text data may be transmitted in binary.
[0022]
The WAP server 122 is connected to the Internet network 125 via a large screen server 123 and a small screen server 124. An ordinary desktop type or laptop type personal computer 126 is also connected to the Internet network 125 via a modem or a router (not shown).
[0023]
As is well known, the personal computer 126 directly downloads data described in HTML (hypertext markup language) or the like of a corresponding URL of the Internet network 125 via a modem or a router and displays the data on the display 127. On the other hand, each portable information terminal 100 ₁ ,... 100 _N of the present embodiment receives the binary data via the WAP server 122 and displays it to reduce the image processing burden.
[0024]
In the conventional mobile phone, since the display size is small, data is downloaded from the Internet network 125 to a small screen server 124 from a home page written mainly for the mobile phone using characters. Then, it is directly converted into binary data for displaying information for each screen described above and transmitted to the corresponding _{one of} the base stations 121 ₁ ,... 121 _M.
[0025]
Also in this embodiment, the data downloaded to the small screen server 124 by this method may be transmitted to the corresponding _one of the base stations 121 ₁ ,... 121 _M , but it is transmitted to the WAP server 122 as a whole. From here, transmission is made to the corresponding _{one of} the base stations 121 ₁ ,... 121 _M. The large screen server 123 downloads the same type of homepage as the personal computer 126 accesses, and transfers it to the WAP server 122. Although not shown, the WAP server 122, the large screen server 123, and the small screen server 124 are each equipped with a CPU (Central Processing Unit), and each of them is controlled by using a control program stored in a storage medium (not shown). The control operation is performed.
[0026]
FIG. 4 shows the main part of control of the WAP server of this embodiment when any portable information terminal accesses the home page. When any of the portable information terminals 100 ₁ ,... 100 _N shown in FIG. 3 designates a URL for accessing the home page (step S141: Y), the requested portable information It is determined whether the terminal 100 is in a large screen mode or a small screen mode other than that (step S142). Here, the large screen mode is a mode for displaying on the display unit 104 larger than the conventional display as shown in FIG. That is, when the portable information terminal 100 according to the present embodiment requests display of a home page, the WAP server 122 determines that processing in the large screen mode is requested. On the other hand, when a home page 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 is used for display.
[0027]
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 it is a large screen mode for displaying a large screen (step S161: Y), data is acquired using the large screen server 123 and displayed on the 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 form 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 this and other data can also be displayed. In order to divide and display one image in two, for example, the image data displayed in the bitmap memory for one page is divided into two areas and read, or one image is displayed in two bitmap memories. A conventional method such as reading and reading while dividing the line in half may be used.
[0028]
If it is determined in step S161 that the mode is not the large screen mode but the small screen mode (N), data is acquired using the small screen server 124 and displayed on the small screen display. (Step S163). A small image can be displayed on the small-screen display as a whole, centering on characters and symbols.
[0029]
Returning to FIG. 4, the description will be continued. If it is determined that the mode is the large screen mode (step S142: Y), the home screen used by the normal personal computer 126 is accessed using the large screen server 123 and the data is transferred from the large screen server 123. The data is received, compiled, converted into binary data, and transmitted to the corresponding portable information terminal 100 (step S143). In the case of the small screen mode (step S142: N), the small screen server 124 is used to access a so-called mobile homepage, receive the data, compile it, convert it to binary data, and Is transmitted to each portable information terminal 100 (step S144).
[0030]
If there is a gap that cannot be displayed in the adjacent portion of the first liquid crystal display 111 and the second liquid crystal display 112 like the display of the portable information terminal 100 of the present embodiment, a homepage is produced. Image information processing on the premise that the display side and the display side are divided and displayed in advance on two screens (that is, the two screens do not adopt a display form as if one screen is substantially constituted continuously). It may be preferable to perform. For example, when there are a plurality of image data on one page, the processing is such that these are displayed close to one side so as not to cross the boundary between the first liquid crystal display 111 and the second liquid crystal display 112. is there. In this sense, it can be said that the image is divided into two and displayed, or can be said to be divided into two and displayed. The homepage production side may perform in advance such that the two liquid crystal displays 111 and 112 do not cause problems in display, or the WAP server 122 side may perform processing such as image alignment. In the case of data that cannot be handled on the WAP server 122 side, large screen data for a plurality of displays other than the normal description format acquired by the personal computer 126 is prepared at the stage of accessing the Internet network 125. May be obtained.
[0031]
FIG. 6 shows a main part of control of the WAP server capable of switching between a screen division mode as a mode for dividing and displaying in two screens in advance and a display mode other than this. In this example, the WAP server 122 determines whether or not the portable information terminal 100 requests display in the screen split mode (step S181). If the display is requested in the screen split mode, the split processing is performed. It is divided into two-screen display by accessing the homepage you have visited or by moving the display position of the bitmap image in the homepage data, etc., and binary data for each screen It is created and transmitted to the portable information terminal 100 (step S182). Therefore, the portable information terminal 100 may display these divided binary data on the corresponding displays. If display in the screen division mode is not requested, binary data for one screen is transmitted (step S183). If the portable information terminal 100 that has received this has one display, it is displayed as it is.
[0032]
Note that the screen division process performed by the WAP server 122 described with reference to FIG. 6 can be directly performed by the portable information terminal 100 as long as it is a process that is simply divided into two and displayed as described above. In the present embodiment, the server is divided into the WAP server 122, the large screen server 123, and the small screen server 124 so that the description can be better understood. It is of course possible to configure as
[0033]
First Modification [0034]
FIG. 7 shows a first modification of the portable information terminal of the present invention. The portable information terminal 200 according to the first modification has a folding structure that can be opened and closed left and right by a hinge mechanism 201. As shown in the figure, the first liquid crystal display 211 and the second liquid crystal display 212 are arranged close to each other in an opened state, and various information can be displayed on a large screen using these. In this modification, a normal key group 202 is arranged under the first liquid crystal display 211, and pointing is performed on the lower side of the second liquid crystal display 212 by inputting position information by tilting with a finger in each direction. A pointing device 204 for inputting position information by pressing the device 203 or the pad with a finger or the like is arranged, and the operability of images and the like is improved in combination with the cursor key 205. Therefore, even when one piece of image information is divided into two and it is difficult to see the boundary portion, the state of the image at the boundary portion can be grasped by a method such as scrolling the image left and right.
[0035]
In this modification, the surface on which the key group 202, the pointing device 203, and the like are not held together with the portable information terminal 200 closed is slightly depressed.
[0036]
Second Modification [0037]
FIG. 8 shows a second modification of the portable information terminal of the present invention. The portable information terminal 300 according to the second modification can be folded into a Z-shape by using two hinge mechanisms 301 and 302, and usually uses a relatively small liquid crystal display 304 for display. Use in a folded state. At this time, the operation key 305 is used for the operation.
[0038]
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 in a state where the operation keys 305 can be operated. Therefore, various information can be displayed on a large screen using these.
[0039]
Of course, in the second modification, the liquid crystal displays on the three surfaces can be the same size. In this case, when viewing a simple liquid crystal display on a single liquid crystal display, when a large screen is required, the portable information terminal is expanded to display information on three screens. Similarly to the case of the third modification described below, for example, the left and right images are displayed one by one on the displays located at both ends of the three liquid crystal displays, and these are viewed with different eyes, respectively. Can also be performed.
[0040]
Third Modified Example [0041]
FIG. 10 shows a third modification of the portable information terminal of the present invention. The portable information terminal 400 of the third modification includes an image display jack 403 on the upper part of a portable information terminal main body 402 having a relatively small display 401 that has been conventionally used. When the terminal of the head-fixed display 404 is connected to the image display jack 403, a relatively large screen image is visually obtained with a single eye or both eyes through the display unit 405 using a liquid crystal or an optical system. Will be. When reproducing an image with both eyes, the image is obtained by acquiring the image from a stereoscopic homepage, separating it into left and right images as necessary, and sharing them on two left and right displays. Visualization is possible.
[0042]
In the third modification, if a display device (not shown) such as another large screen type CRT or a liquid crystal display is connected to the image display jack 403, the homepage of the Internet is displayed with a large screen image in the same manner. Etc. can be displayed. The portable information terminal main body 402 determines whether or not the display device is connected to the image display jack 403 and determines whether or not the large screen mode described with reference to FIG. Will be different.
[0043]
In the third modification, the seam of the displayed large screen image does not occur. In particular, the apparatus shown in FIG. 10 can easily acquire high-resolution information on a large screen with the display 404 on the go. Moreover, since the image information for each screen is converted into binary data and sent to the portable information terminal main body 402 on the WAP server 122 side, for example, even if it is moving image information or information that requires special conversion processing, the WAP server 122 side. Thus, high speed processing can be performed by drawing all these processes. Therefore, although common to the previous embodiment and other modifications, information on a large screen and high resolution can be obtained without requiring a download of a program such as a plug-in or a high-speed CPU or an image processing circuit on the receiving side. Can be easily obtained. Therefore, depending on the type of information to be acquired and the communication speed environment, the portable information terminal main unit 402 connects to a home display or television via the WAP server 122 rather than accessing the home page with a personal computer provided at home. The image information can be obtained under better conditions.
[0044]
Fourth Modified Example [0045]
FIG. 11 shows a fourth modification of the portable information terminal of the present invention. The portable information terminal 500 of the fourth modification includes a transmission type liquid crystal plate 501 and a light source and an optical system (not shown) for enlarging and displaying an image displayed thereon on the display panel 502. The portable information terminal main body 503 is connected to the power source 505 when displaying an enlarged image in this way. In this modification, the power source 505 also serves as a stand for the portable information terminal main body 503.
[0046]
The portable information terminal 500 according to the fourth modified example needs a power source 505 except for a display for a short time. However, the portable information terminal 500 is enlarged by using a familiar place or object such as a wall, a notebook, or white paper. The obtained image can be easily obtained, so that it is most suitable for a presentation or the like.
[0047]
Although the embodiment has been described mainly with respect to the portable telephone, it is natural that the present invention can be applied to the entire portable information terminal using a wireless or wired communication line. Moreover, although the liquid crystal display was used as a display in the Example and the 1st-3rd modification, it is free to use displays other than a liquid crystal. Of course, these displays may be capable of displaying color or displaying monochrome images. Further, although the WAP server is used in the embodiment, the present invention is not limited to the server using such a special protocol, and the point is that the intermediate processing for performing the image processing for reducing the burden on the portable information terminal side. Any image conversion means may be used.
[0048]
In the fourth modification, information appearing on the transmissive liquid crystal or the object is enlarged and displayed. However, information appearing on the reflective liquid crystal or the object can be enlarged and displayed. Of course, the present invention is applicable to these. Further, in the fourth modification example, the power source 505 connected to the portable information terminal 500 has been described as a device that simply supplies power. However, an optical enlarging mechanism is prepared in the device and displayed from the portable information terminal 500 side. The image data to be received may be received, and an enlarged image may be displayed on the wall or the like as shown in FIG. In this case, the portable information terminal 500 does not necessarily need to be supplied with power from the outside (the advantage is that the portable information terminal 500 is charged if it is integrated with a charger) and receives image data to be displayed. It suffices if a terminal is provided. In this case, the concept is common to the external display of the image in the third modification shown in FIG.
[0049]
In addition, each display used in the present embodiment and the modification may be configured by one component such as a liquid crystal display, or the one described as one liquid crystal display is a plurality of components such as a plurality of liquid crystal displays. It may be comprised. It is also possible to reduce the manufacturing cost by downsizing each display. The display 404 of the third modified example is shown for a single eye, but may be for a binocular. Further, although the image display jack 403 is used to connect to the display unit 404 by wire, it is naturally possible to connect the display unit 404 wirelessly.
[0052]
【The invention's effect】
As described above, according to the present invention , the image data transmission server determines the mode requested by the portable information terminal, and based on the image data received by the image data receiving means, the left and right images for stereoscopic viewing The image data for each screen separated into two is created and transmitted to the portable information terminal that requested the stereoscopic display. Therefore, for example, even a portable information terminal with low processing capability can easily display a relatively large screen or high-resolution display including an image or the like.
