Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information providing service system for portable information terminals.

[0002]

2. Description of the Related Art In recent years, with the development of information and communication technology and the development of communication infrastructure, it has become possible to provide a service that provides users with multimedia information including images as well as characters using the Internet. Generally, the hypertext format called HTML is used for the distribution of multimedia information, and the user browses the data in this format using software called a browser on a terminal. Here, the operation from when the browser receives the hypertext data including the inline image until it is displayed on the terminal will be described.

FIG. 32 is a block diagram of a conventional browser.
In FIG. 32, 3201 is an input control means for receiving an instruction from a user, 3202 is a communication control means for transmitting and receiving data through a network, and 3203 is for reading and storing data in a secondary storage device on the terminal. The storage control means 3204 is a document acquisition means for acquiring the hypertext data using the communication control means 3202 or the storage control means 3203 according to the designated reference destination of the hypertext data. The storage control means 3205 is the input control means 3201. Document analysis means for specifying the reference destination of the hypertext data from the instruction received and analyzing the hypertext data acquired by the document acquisition means 3204;
Reference numeral 3206 denotes a document allocation display unit that generates display data based on the hypertext data analyzed by the document analysis unit 3205 and presents it to the user.

The operation of the browser configured as described above to display hypertext including an image will be described. When the user gives an instruction to display a new hypertext by referring to a link or the like, the input control unit 3201 transmits the instruction to the document analysis unit 3205. Document analysis means 32
In step 05, the instruction is transmitted to the document acquisition unit 3204 to acquire the hypertext. Here, the instruction is http: //
If the display is / host1 / page1, the document acquisition unit 3204 determines that the hypertext data is referenced on the external host1, so that the communication control unit 320
2 and communicate with host1 to acquire hypertext data page1. Here, the hypertext data page1 will be described with reference to FIG. Three
Reference numeral 301 denotes an example of an HTML document. <IMG> is an instruction to paste image data. In this example, image data logo1, image data redball, "text 1", image data redball, "text 2",
This indicates that the image data is allocated in the order of the image data line1 and the image data gohome. FIG. 34 shows an example of an allocation result. Reference numeral 3401 denotes image data logo1.
3402 is the content of the image data redball,
Reference numeral 3403 denotes the content of the image data line1, and reference numeral 3404 denotes the content of the image data gohome. Returning to the description of the operation, the document analysis unit 3205 analyzes the hypertext data page1 and needs to paste the image data.
It instructs acquisition of image data redball and image data line1. Since the reference destination of the hypertext data is on the external host1, the document acquisition unit 3204 communicates with the host1 using the communication control unit 3202 to acquire the image data logo1, the image data redball, the image data line1, and the image data gohome. I do. Next, the document analysis unit 3205 passes the analysis result of the hypertext data page1 and the acquired image data to the document allocation display unit 3206. Document allocation display means 3206
Then, character data and image data are arranged, display data corresponding to FIG. 34 is generated, and displayed on a liquid crystal display or the like.

The above-described method is a method of acquiring image data from a link destination and displaying the image data in a page. However, since a time for data transfer is included, it takes time to complete the display processing of the page. There is also a general method that completes the page display process only by displaying an icon indicating that there is an inline image and / or one of the alternative character strings, and acquires image data only when the user gives an instruction later. Is used regularly. FIG. 35 shows an example of the allocation result of this method. 3501 expresses the presence of image data logo1 by an area and an image icon, 3502 expresses the existence of image data redball by an image icon and an alternative character string, and 3503 Represents the presence of image data line1 in an area, and 3504
Indicates that the image data gohome is represented by an image icon and an alternative character string. In this method, the document analysis means 3205 uses the hypertext data p
Even if it is necessary to analyze page1 and paste the image data, the analysis result of the hypertext data page1 is not obtained and the document allocation display means 320 is obtained.
Pass to 6. The document allocation display means 3206 arranges an icon indicating that there is character data and image data and a substitute character string, generates display data shown in FIG. 35, and displays it on a liquid crystal display or the like. Thereafter, when there is an instruction to display an image from the user, the document analysis unit 32 is operated in the same manner as the former method.
05 obtains image data and performs document allocation display means 320
In step 6, data for display is generated.

In a text-only browser having no image display means, only the value of an alternative character string attribute or a reference character string is displayed in the latter method. FIG. 36 shows an example of an allocation result of this method. 3601 expresses the presence of image data logo1 by a reference character string “logo1”, and 3602 expresses the presence of image data redball by an alternative character string “redball”. And 3503
Indicates that the image data line1 is present by a substitute character string “horizontal line”, and 3504 indicates that the presence of image data gohome is represented by a substitute character string “go home”.

[0007] In addition, a hypertext including a table expressed in HTML can be displayed on a browser, but in this case, the number of characters to be displayed in the horizontal direction becomes large and scrolling is often required. For this reason, some browsers for portable information terminals with a small display screen have attempted to avoid scrolling by calculating the horizontal width specified by the original data by half.

[0008]

However, the latter method of the prior art described above has a problem that when one page contains a large number of inline images, the readability of the page is greatly deteriorated. In particular, when an in-line image is used to improve the design of a mark for a bullet or a horizontal line indicating a column break, the readability becomes remarkable. Further, even when the image display is instructed and the image is designed for design with little information amount, communication costs and service usage fees are charged, which is uneconomical with respect to the information amount.

Also, a text-only browser having no image display means can only display a substitute character string, and the existence of an image for the purpose of design only deteriorates the legibility of the page and is not used effectively at all. There are issues.

[0010] Another problem is that even if the page creator wants to show that the image is designed and intended to be displayed alternately, the image cannot be displayed.

Another problem is that when image display is instructed and image data is acquired, effective use for subsequent alternative display is not considered.

In addition, in the display of a table on a small screen such as a portable information terminal, scrolling is often required when the width of each cell is small, and it is difficult to read due to folding back. There is a problem of lack of listability.

[0013] The present invention solves the above-mentioned problems. In displaying a page including an inline image in browsing a hypertext, no time is spent for data transfer and the readability of the page is not degraded. The primary purpose is to maintain the design.

A second object is to make effective use of an image for design purposes even in a text-only browser.

It is a third object of the present invention to ensure that a replaceable image with a small amount of information, such as an image for the purpose of design, can be alternately displayed by a browser when the page creator intends.

It is a fourth object of the present invention to improve the effect of alternative display by effectively using image data when image data is actually obtained.

It is a fifth object of the present invention to improve the visibility of a part to be watched by a user in displaying a table on a small screen.

[0018]

In order to achieve the first object, the present invention firstly provides an alternative image storage means for storing alternative image data for alternative display without acquiring image data; Image content inference means for inferring the content of the image from document data and determining an alternative image.

Thus, in displaying a page including an inline image in browsing the hypertext, it is possible to maintain the design without spending time for data transfer, deteriorating the legibility of the page, and maintaining the design.

In order to achieve the second object, the present invention provides a second method.
Further, there is provided an alternative character inference means for inferring the contents of the image of the reference destination from the document data and determining an alternative character string.

As a result, the image for the purpose of design can be effectively used even with a text-only browser.

In order to achieve the third object, the present invention provides a third method.
And an alternative image storage unit that stores alternative image data for alternative display without acquiring image data, and an alternative image selection unit that determines an alternative image from alternative image information added to link data.

Thus, when the page creator intends, a replaceable image with a small amount of information, such as an image for the purpose of design, can be surely displayed alternately by the browser.

In order to achieve a fourth object, the present invention provides a fourth method.
Further, there is provided an image content learning means for reflecting the content of the acquired image on the substitute image data and the image content inference means.

Thus, when the image data is actually obtained, the data can be effectively used to improve the effect of the alternative display.

In order to achieve the fifth object, the present invention provides a fifth method.
And a table matrix conversion unit and a specific matrix display unit.

Thus, in displaying the table on the small screen, it is possible to improve the listability of the part that the user gazes at.

Here, the flow of processing of the image content inference means 107 will be described with reference to FIG. First, the information of the image data logo1, which is the first to be inferred, is collated with the substitution rule (step 4-1). Here, FIG. 5 shows an example of the substitution rule. Reference numeral 501 denotes a plurality of image data of the same reference destination appearing on the same page, and the reference destination character string is a graphic keyword character string dot, ball / square.
In the case of including “e”, “rect / line”, and “bar / arrow”, the rule indicates that the substitute image “ball” / “square” / “line” / “arrow” can be substituted for each keyword character string. 502, the image data is located in the link, and the reference character string is the button keyword character string next / back / home / yes / no.
In the case where "" is included, the rule indicates that the alternative image corresponding to each keyword character string can be replaced with "Next" / "Return" / "Home" / "Yes" / "No". 50
Reference numeral 3 indicates a rule that when the image data is located in the link and the image data of the same reference destination appears three or more times on the same page, the image data can be replaced with the substitute image “button”. Reference numeral 504 denotes HEIGHT indicating the size of image data.
And WIDTH attributes are specified and HEIGHT
If <16 and WIDTH <16, HEIGHT <12 and WIDTH> 1 are added to the substitute image “ball”.
When the value of 00 is satisfied, the rule that each of the alternative images “line” can be replaced is indicated. Returning to the flow of the processing, the information of the image data logo1 does not conform to any of the rules, and as shown in 201 in FIG.
No. 1 adds information that it is impossible to substitute to the inference result information (step 4-2). Next, returning to step 4-1, the information of the image data redball is collated with the substitution rule. This matches the rule of 501 because a plurality of characters appear on the same page and the reference character string includes the graphic keyword character string "ball". In step 4-2, as shown in 202 in FIG. Is added to the inference result information. Next, step 4-1
To check the information of the image data line1 against the substitution rule. This is HEIGHT and WID indicating the size
TH attribute is specified, HEIGHT <12 and W
Since IDTH> 100 is satisfied, the rule of 504 is satisfied, and as shown in 203 of FIG.
“e” adds to the inference result information information that the substitute image “line” can be substituted. Next, returning to step 4-1, the information of the image data gohome is compared with the substitution rule.
Since this is located in the link and the reference character string includes the button keyword character string home, it conforms to the rule of 502, and in step 4-2, as shown at 204 in FIG.
home adds information that the substitute image “home” can be substituted to the inference result information. This completes the evaluation of all the image data, thus ending the processing.

Therefore, even if the setting is not to acquire the image data, the image data redball, line1, and gohome for the purpose of design are displayed alternately as shown in FIG. The legibility and design are improved as compared with the display according to the above method. Further, even when an image display is instructed, it is sufficient to acquire only the image data logo1 that cannot be replaced, and communication costs and service usage fees can be saved.

In this embodiment, only a small number of alternative rules have been described. However, the number of keywords is increased (combination with color names such as bullet as graphic keywords, enter, netscape as button keywords, etc.) It is possible to improve the inference correctness rate by evaluating a value or evaluating a position in a document structure such as a paragraph or a table. In addition, since the inference may be wrong, the mode can be switched to a mode in which the inference is invalidated, so that browsing can be performed at the discretion of the user.
