DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a markup language, such as HTML (Hy
The present invention relates to a proxy server or a recording medium recording a program for reediting a page created in Per Text Markup Language.

[0002]

2. Description of the Related Art Conventionally, WWW pages have been created using H
TML is used. Initially, pages were primarily text, but with the spread of the commercial Internet and personal computers, images have become more frequent. Usually, in order to compose a complicated layout using an image, a table tag and an image tag are often used in combination.

[0003] Also, pages created in HTML are created on the assumption that they are viewed on a display screen of a personal computer. Therefore, in order to browse these pages with a portable terminal having only a small display screen, it is necessary to perform not only vertical scrolling but also horizontal scrolling.

In a portable terminal, in order to eliminate the need for horizontal scrolling and to make it easier to view, the display size of the outer frame of the table is marked up so as to be uniformly reduced corresponding to the small display screen of the terminal. There is a first way to re-edit the language. In addition, an H for a table of contents is automatically created by extracting only characters described in a specific tag.
There is also a second method of dividing a TML document into a plurality of HTML documents created by extracting a document between the tags. References include Naoko Ito, Hengo Tachikawa, Yoshihisa Nakagawa, and Yasuhiro Mizukoshi, "WWW Page Conversion for Mobile Devices-SmartProxy" (1

However, in the first method, the table is reduced in size as a whole, and it is difficult to visually recognize the table in the portable terminal. In the second method, when images are frequently used and do not have a format as a document, it is difficult to specify a specific tag as a reference.

Accordingly, the present invention solves the above-mentioned problems, and provides a proxy server, a method, and a program for reediting a page created in a markup language so that the page can be easily visually recognized even on a small display screen of a terminal. It is an object of the present invention to provide a recorded recording medium.

[0007]

According to the present invention, there is provided a proxy server for reediting a page, comprising: a first means for deleting a table tag for a page constituted by a table tag and an image tag; Second means for changing the value of the width and height of the image tag corresponding to the ratio of the value of the width of the display screen of the terminal to the value of. By deleting the table tag, the frequency of the horizontal scroll operation on the terminal can be reduced, and the operability of the terminal can be improved. Also, after deleting the table tag, the width of each image is changed to the width of the display screen of the terminal, so that the operation of the terminal does not require horizontal scrolling.

[0008] According to another embodiment of the present invention, the first means includes, in the case of a nested structure in which the elements of the first table are the second table, at least one of the last table in the nested structure. It is also preferable not to delete the tag of the table of. By doing so, the small display screen of the terminal may be visually recognizable in some cases.

Further, according to another embodiment of the present invention, the first means does not delete the table tag when the width of the table displayed by the table tag is smaller than the width of the display screen of the terminal. It is also preferred. It is preferable that the table of a size that can be displayed on the display screen of the terminal be displayed in the state of the table as much as possible.

[0010] According to another embodiment of the present invention, it is preferable that the second means deletes the image tag according to the type of the attribute set in the image tag.
The information necessary for the terminal user is information of each element of the table tag, and does not require an image used only for layout. In particular, since the original layout is destroyed by removing the table tag, the image used only for the layout causes the terminal user to confuse visual recognition. Therefore, by deleting such an image tag, the page can be re-edited so that it can be more easily recognized.

Further, according to another embodiment of the present invention, it is preferable that the first means and the second means can be selected to be executed by an instruction from a terminal.

According to the method of re-editing a page of the present invention, for a page composed of a table tag and an image tag, a first step of deleting the table tag and a width of the display screen of the terminal with respect to a value of the width of the image tag. A second step of changing the values of the width and height of the image tag in accordance with the ratio of the values of the image tags.

According to the present invention, there is provided a recording medium on which a program for reediting a page is recorded, wherein a table tag is deleted from a page constituted by a table tag and an image tag, and the width of the display screen of the terminal with respect to the width value of the image tag. Has a program for changing the values of the horizontal width and the vertical width of the image tag according to the ratio of the values of the image tags.

Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is a flowchart of page reediting according to the present invention. FIG. 2 is an example of a page to be re-edited. FIG. 3 is an example of a page after the page of FIG. 2 has been re-edited.

This will be described with reference to the flowchart of FIG.
When a notification that the user wants to refer to the page in FIG. 2 is received from the mobile terminal, the page is re-edited. First, the page of FIG. 2 is fetched from the server holding the page (1). Next, if the table tag deletion setting (2) previously notified from the portable terminal is “present”, the table tag of the page is deleted (3).

Deletion of a table tag is, for example, deletion of a tag as follows. <TABLE><TR><TD> a </ TD><TD> b </ TD></TR><TR><TD> c </ TD><TD> d </ TD></TR>< / TABLE> ↓ a <P> b <P> c <P> d <P>

Deletion of table tags is indicated by reference numerals 9, 10
And 11. For example, suppose that the parent table 1 is a table like the reference numeral 9. Parent table 1
Elements a, b, and
c and d are displayed. Similarly, child table 1-2
Have elements e, f and g, and child table 1-3 has element h.
However, elements i, j, k, and l are displayed in the child table 1-4. In this case, by deleting the table tag of the parent table 1, the tables are arranged vertically like reference numeral 10. At this time, each child table
It is preferable that the information is sufficiently displayed on the screen of the mobile terminal. If the child table is reduced in size because the child table is larger than the screen of the mobile terminal and the screen display becomes difficult to recognize, it is preferable to delete the table tag of the child table. Further, by deleting the table tag of the child table, all elements are arranged vertically as indicated by reference numeral 11. In a mobile terminal, all these elements can be recognized only by vertical scrolling.

For example, the page configuration shown in FIG. 2 is composed of a table 1 containing a banner image or the like in which a horizontal KDD is described at the top, and a table 2 containing a plurality of tables. The table 2 is composed of three rows of tables 2-1 to 3-2, an image, and a text. Tables 2-1 to 2-2 have a nested structure of Table 2. These tables are configured using table tags specified by colorless lines.

When the table tag of the page shown in FIG. 2 is deleted, one vertical column of pages is created as shown in FIG. At this time, the image of the rounded frame surrounding “MENU” in FIG. 2 is displayed as an undisplayable image in FIG. Such display occurs because the layout location of the layout image is changed due to the deletion of the table tag, and the layout image is not displayed as a frame. Such an image is determined to be an image only for the layout. Therefore, if the image tag deletion setting (4) specified in advance from the portable terminal is “present”, an image only for such a layout is selected as a deleteable image (5), and the tag of the image is selected. Is deleted (6).

The factors that determine that the image is not just an image for layout, that is, an image that needs to be displayed, include an ALT attribute or the like set in the image tag or an image in the A tag. Tags are nested. The following is an example of HTML determined to be not an image only for layout. <A HREF="apple/index.html"<IMGSRC="apple.gif"ALT="This is an apple"></A> The ALT attribute moves the mouse point over the image. This is a description character that is sometimes displayed.Images that require explanation are not deleted.
The A tag specifies a link button. In addition to these, the USEMAP attribute may be specified. The USEMAP attribute specifies a shape and coordinates or a link destination that can be linked in an image. Thus, an image that gives a choice to the viewer is not a deletion target. Conversely, the following image, which only specifies the display of the image,
Be subject to deletion. <IMG SRC = "apple.gif">

Next, the image is reduced so that it can be displayed on the terminal screen (7). That is, the values of the width and the height of the image tag are changed corresponding to the ratio of the value of the width of the display screen of the terminal to the value of the width of the image tag.

If the image tag is <IMG SRC = "apple.gif" WIDTH = "100" HEIGHT = "50"> that specifies a landscape image, if the width of the terminal display screen is 100, Do not change anything as follows. <IMG SRC = "apple.gif" WIDTH = "100" HEIGHT = "50"> However, if the width of the terminal display screen is 50, change as follows. <IMG SRC = "apple.gif" WIDTH = "50" HEIGHT = "25"> At this time, the ratio between WIDTH and HEIGHT is not changed.

Finally, the re-edited page is output to the portable terminal (8).

The above-described various embodiments of the proxy server for re-editing the page of the present invention, the method, and the recording medium on which the program is recorded have various changes, corrections and omissions in the technical idea and scope of the present invention. According to those skilled in the art, this can be easily performed. The foregoing description is merely an example, and is not intended to be limiting. The invention is limited only as defined by the following claims and equivalents thereof.

[0026]

As described above in detail, according to the present invention, when a page supposed to be browsed on a screen of a personal computer is browsed on a screen of a portable terminal, an operation of only vertical scrolling is performed. Can be browsed. Also,
By deleting the images determined not to be necessary as information, the operability of the screen on the mobile terminal is also improved.
