43). It is determined whether the analyzed script indicates an image file (S945). If the script is an image file, an instruction is given to the reading unit 910 to read the image file (S955). Then, the read image file is developed by the image developing unit 916 according to the type of the image file (S959).
If it is not an image file, another process is performed as shown in S957. Next, in S961, it is determined whether the description of the hypertext is completed, and the analysis of the hypertext is repeated until the description is completed. The result analyzed by the hypertext analysis unit in this way is sent to the layout configuration unit 918. The image data expanded by the image expansion unit 916 is also sent to the layout configuration unit 918. The layout configuration unit 918 configures a layout of a homepage to be displayed using the analysis results and the developed image data. The display unit 920 displays a homepage according to the layout created by the layout configuration unit 918. Thus, the conventional web browser displays hypertext.

[0007] The transmission speed and screen display capability supported by the information processing device (client) connected to the server are various. For an information processing apparatus having a relatively low transmission speed or an information processing apparatus having a limited screen display capability, downloading and displaying image data included in a hypertext is a very burdensome operation. Therefore, some information processing apparatuses do not display image data among data included in the hypertext in order to escape the load. However, in this case, if there is a link to another hypertext in the image data that is not displayed, the display of the link page icon cannot be seen and the user cannot move to the link page.

[0008] HTML (Hyper Text Ma), which is an example of the above-described hypertext description language, is used.
rkup Language) contains hypertext (for example, a Web homepage).
When the information processing apparatus that displays the Web homepage does not support image display, a format is provided in which text display explaining image display is performed instead of image display. This is a format for assuming the function of the information processing apparatus when creating a hypertext in advance, and unless a description in the format is prepared on the web page of the Web,
It cannot be used only by the browser that displays the home page of b.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiment 1 In this embodiment, a description will be given on the assumption that a hypertext is described in an HTML language used on the Internet as a specific example. FIG. 1 is a diagram showing an example of an environment to which the hypertext display system of the present invention is applied. Reference numeral 1 denotes a plurality of servers connected to the Internet 2000. The information processing device 90 is connected to the Internet via a communication line. And Internet 2
000 is connected to the server 1. The hypertext display system 100 of the present invention is applied to the information processing device 90. Information processing device 9
0 assumes a device having a communication function connectable to a normal personal computer and a server and a display function for displaying data. PHS (personal h
An Android phone or a portable information device using a mobile phone as a communication means may be used. Communication means include ordinary telephone lines and ISDN besides PHS and mobile phones.

k), etc., the connection to the server via a cable is also possible.

As an example of an information processing apparatus having a limited transmission speed, consider a case where a portable information processing apparatus is used. Current PH used in portable information processing devices
Communication protocol PIAFS (PHS In
ternet AccessForum Standa
rd) is a transmission rate of 32 kbit / s. This is much slower than connecting via ISDN,
The time for reading the same file can be quite different. The size of the display screen is, for example, 640 × 480 dots in the case of a VGA in a personal computer, while it is 23 in the case of a portable information processing device.
Some are 9x160 dots, and it seems that there is a considerable difference in displaying the same hypertext file.
Further, the processing performance of the CPU also affects the download and display of the homepage.

FIG. 2 is a block diagram showing functions of the hypertext display system of the present invention. The hypertext display system 100 reads the hypertext via the communication line 1000 from the reading unit 10 to the display unit 20.
It consists of. Hypertext analysis unit 14
Has an image file reading unit 15. Other processing units, that is, the reading unit 10, the storage unit 12, the image development unit 16,
The layout composing section 18 and the display section 20 correspond to the reading section 910 to the display section 920 shown in FIG.

FIG. 3 is a flowchart showing the processing procedure of the hypertext analysis unit and the image file reading unit of the present invention. The processing of S11 to S15 in FIG.
Since the processing corresponds to the processing of steps 941 to S945, the description is omitted. If it is determined in S15 that the description (script) of the read hypertext is an image file, the image file reading unit determines in S17 whether the image file has a link. If there is a link, the image file shown in S25 is read.
Next, the image developing unit 16 performs the image developing process shown in S29. This processing corresponds to the processing of S955 and S959 in FIG. If there is no link in the image file in the determination of S17, the image file reading unit 15
An instruction to display an alternative icon at a position where the image file should be displayed is created and output without reading the image file (S27). For alternative icon display,
It will be described later. If it is determined in step S15 that the file is not an image file, another process is performed in step S19. The above processing is repeated until the hypertext read from the storage unit 12 ends.

Next, the display of the substitute icon will be described with reference to the drawings. FIG. 4 is a diagram showing an example of a hypertext displayed by the hypertext display system of the present invention. FIG. 5 is a diagram showing an HTML description corresponding to the display of the hypertext shown in FIG. Reference numerals 51 to 59 in FIG. 5 are descriptions corresponding to the displays 30 and 32 in FIG. Numeral 30 is a display of the image file shown at 53, and as shown at 51, '. / Inde
x_e. The file is linked to the file "htm '". Also, the character string “English” shown in 32
Version 'is also linked as described at 51. The underline of 32 indicates that this character string is linked. Note that, in the description of the hypertext illustrated in FIG. 5, descriptions regarding other character strings displayed in FIG. 4 are omitted. Reference numeral 34 in FIG. 4 denotes the display of the image file described in 65 in FIG. As described above, the HTML description shown in FIG. 5 is displayed as shown in FIG. 4 by the conventional web browser.

Next, a display example by the hypertext display system of the present invention will be described with reference to the drawings. FIG. 6 is a view showing an example of hypertext displayed by the hypertext display system of the present invention (display of an image without a link is omitted).

The operation will be described with reference to the flowchart of FIG. 5 in FIG.
When the script shown in FIG. 3 is analyzed, it is an image file, so the determination in S15 is Yes, and in S17, it is further determined whether there is a link. Since the description of 53 is linked as shown at 51, the result is Yes, and the image file designated by 53 is read in S25, and the read image file is read by S29. The image is developed by the image developing unit 16. The developed image is displayed as shown at 30 in FIG. Next, for the image file described in 65 of FIG. 5, it is determined that there is no link in the determination of S17, so the result is No, and an alternative icon display instruction is created as shown in S27. As a result, the originally specified image file '. / Image / 97summer / s
hop. gif 'is not displayed, and an alternative icon 74 indicating that the image file should have been displayed is displayed as shown in FIG.

As described above, the image file reading unit 15 determines whether or not there is a link in response to the designation of the image file. If there is a link, the image file is read. By giving an instruction to display an alternative icon, it is possible to omit reading, analysis, and display processing of an image file that places a load on the information processing apparatus. Furthermore, since the image file having the link is read or displayed, it is possible to avoid a situation where, when the display of all the image files is omitted, it is not possible to move to the link destination where the image file is attached.

Next, at step S25 in the flowchart of the process shown in FIG.
The case where the processes of and S27 are performed in reverse will be described. That is, when there is a link, an instruction to display an alternative icon is issued, and when there is no link, an image file is read or displayed. FIG. 7 is a diagram showing an example of hypertext displayed by the hypertext display system of the present invention (the display of images with links is omitted). When there is a link to the HTML description shown in FIG. 5, when the image file reading unit 15 operates to display an alternative icon, as shown in 70 in FIG. About the image file
The replacement icon is displayed without loading. Also,
For the description without a link (65 in FIG. 5), as shown at 34 in FIG. 7, the image file is read, and the image is developed and displayed.

As described above, the image file to which the link is attached is not read or displayed, but the icon is displayed instead, so that the display of the hypertext corresponding to the description to which the link is attached is changed to the display of the image file. It can be completed earlier than when reading is performed, and it is possible to move to the link destination earlier. In this case,
Instead of the icon display shown at 70 in FIG.
May be displayed. FIG. 8 is a diagram showing an example of an icon corresponding to an image with a link displayed by the hypertext display system of the present invention.

FIG. 9 is a flowchart showing another processing procedure of the hypertext analyzer of the present invention. Steps S111 to S119 of the processing procedure illustrated in FIG. 9 correspond to S11 to S19 of FIG. 3 described above, and thus description thereof will be omitted. The image file reading unit 15 acquires the image file size in S121 when the determination is Yes in S117 whether there is a link. Next, in S123, it is determined whether or not the obtained image file size is equal to or smaller than a predetermined threshold. The threshold value compared with the image file size in the determination in S123 is set in advance according to the image processing capability of the information processing apparatus on which the hypertext display system operates. Alternatively, the threshold may be set in consideration of the processing capability of the processor of the information processing device. If the image file size is equal to or smaller than the threshold, the image file is read in S125, and the read image file is expanded by the image expansion unit in S129. If the image file size is larger than the threshold value, the image file is not read and the display of the alternative icon is instructed in S127.
When processing is performed according to this processing procedure, 53 in FIG.
If the file size of the image file specified by is larger than a predetermined threshold, a display as shown in FIG. 10 is performed. That is, although 70 in FIG. 10 has a link,
The alternative icon is displayed when the image file size is larger than the predetermined threshold, and the alternative icon 74 is displayed when there is no link. Similarly, when the processing is performed according to the processing procedure of FIG. 9, when the file size of the image file defined in 53 is equal to or smaller than a predetermined threshold,
The displayed home page is displayed in the format shown in FIG.

FIG. 11 is a flowchart showing another processing procedure of the hypertext analyzer of the present invention. Here, a case will be described in which the image file reading unit 15 does not determine whether there is a link to the image file, but determines whether to read the image file only based on the image file size. If the script is an image file as determined in S215, the image file size is acquired in S221. To obtain the image file size, it is assumed that the browser makes an inquiry about the size of the image file using a function provided in the hypertext display system in advance. For example, an image file size may be obtained using a command to open a file. If the acquired image file size is smaller than the predetermined threshold, the image file is read or the image is expanded (S225, S229). If the image file size is larger than the predetermined threshold, an instruction to display a substitute icon is issued (S227). When the image file reading unit 15 makes such a determination, an alternative icon is displayed as in the case of an image having a large file size, such as 74, as in the case shown in FIG. As shown at 30 in FIG. 6, the image file is read or displayed.

As described above, it may be determined whether or not to read an image file specified only by the image file size, with or without a link. In this case, it is possible not to read an image file having a large image file size, which places a load on the reading unit 10, the image expanding unit, and the display unit.
