DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document browsing apparatus for displaying a document stored in a document storage device such as a document database. The present invention relates to a document browsing device that can be selectively displayed.

[0002]

2. Description of the Related Art A document database having a function of updating stored documents and having a feature that an updated document can be retrieved with the same document name as before updating, and a function of displaying an arbitrary document stored in the document database As a typical example of a document browsing system including a document browsing device having a URL, there is WWW (World Wide Web). In this case, an example of the document is HTML (Hyper-Text Markup Langua).
ge) A WWW server is an example of a document and the document database, and a WWW browser is an example of the document display device. In the document browsing apparatus, when displaying one document, the entire document to be displayed is displayed on a screen of one or more frames. Also, the creator / updater of the document in the document database is different from the viewer, and generally creates / updates the document regardless of the timing of browsing.

[0003]

In displaying such a document in such a document browsing system, the purpose of the viewer should be achieved if only the range required by the viewer can be displayed. However, when displaying a document on the document display device, the entirety of the specified document is displayed on a screen of one or more frames, so that the range required by the viewer in the displayed document is further displayed. To do so, the viewer must search for the necessary range by scrolling the screen or the like. Therefore, when the data amount of the designated document is large, there is a problem that the operation to find the part desired to be browsed is troublesome and time-consuming. In addition, when a document in which the required range has been searched once is updated, the viewer needs to search the required range again.

As described above, the range required by the viewer is
If the document is a part of a document stored in a document database, etc., in order for the viewer to continue browsing the range even after the document is updated, the viewer's There is a problem in that the viewer has to search the required range by himself.

[0005] In addition, even when it is desired to ignore an unnecessary range in a document, there is a problem that the viewer himself must search for a range that the viewer does not need every time the document is updated.

In addition, when the document is updated in the document database while the document is displayed, even if the “range requiring update of display” is a part of the document,
There is a problem that after displaying the updated "entire document", it is necessary to find the part viewed in the state before the update and display it again. Similarly, even if the “range that does not require a display update” is part of the document, after displaying the updated “entire document” including the part that does not need to be updated,
There is a problem that it is necessary to find the part that was being browsed in the state before the update and display it again.

Further, when displaying a document, only the entire document can be displayed, so that a range required by a viewer in the document cannot be displayed as a part of another display destination document. There is a problem. Similarly, there is a problem that a document cannot be displayed as a part of another display destination document except for a range not required by a viewer.

SUMMARY OF THE INVENTION It is an object of the present invention to make it possible to view only a portion selected by a viewer or only a portion other than a designated portion of a document displayed on a document display device without performing a troublesome search operation. It is an object of the present invention to provide a document browsing device capable of doing so.

1). For example, if the document browsing device 2401 is a WWW (World
If the browser is a Wide Web browser, the document name 801 contains the URL
(Uniform Resource Locator).

Next, the document browsing device 2401 obtains the document specified by the document name 801 specified by the browsing user from the document database 104 (step 2702). For example, if the document browsing device 2401 is a WWW browser,
The document database 104 represents a WWW server, and the document browsing device 2401 requires an HTTP (Hype
r-Text Transfer Protocol) is used.

Next, the document browsing device 2401 displays the document acquired from the document database 104 on the display device 101 (step 2703). The above is the document browsing process performed by the existing document browsing device 2401.

Next, for the displayed document,
The range specifying process in the first half of the process shown in FIG. 9 is performed (step 2704). The above is the process of specifying the desired browsing portion 203 in the display source document. In the processing so far, FIG.
Is obtained.

Next, the process is performed when the viewer specifies the same document name 801 as in step 2701 to the document browsing device 2401. First, the viewer reads the document browsing device 24.
01, the same document name 801 as specified in step 2701 is specified (step 2705). Next, similarly to step 2702, the document browsing device 2401 acquires the document specified by the document name 801 specified by the viewer from the document database 104 (step 2706).
Next, the range / point estimation device 2402 performs range specifying processing in the latter half of the processing shown in FIG. 9 (step 2707). As a result, the range / point estimation device 2402 specifies and extracts the desired browsing portion 203. Finally, the document browsing device 2
401 displays the desired browsing part 203 extracted in step 2707 on the display device 101 (step 270).
8). In FIG. 26, the display source range display 1001 displayed on the display device 101 corresponds to the browsing desired portion 203. Thus, the process for obtaining the display shown in FIG. 26 ends.

As a result, even if the contents of the document database 104 are updated, when browsing the document information with the same document name, only the part first designated as the part desired to be browsed is immediately displayed. As a result, effects such as saving the usage fee of the communication line can be obtained.
