Next, the operation of the computer system 1 will be described. FIGS. 5 and 6 are flowcharts showing single page display processing executed by the computer system 1 according to the embodiment to which the present invention is applied. The single-page display process shown in FIGS.
The process is executed when only one page of the document stored in the storage device 16 is designated by the instruction input from the user 2.

First, when a page to be displayed is specified by an instruction input from the input device 12 (step S1), the CPU 11 stores an attribute page object E corresponding to the specified page in the RAM 13. It is determined whether or not there is (step S2). Here, when the corresponding attribute page object E is not stored in the RAM 13, the CPU 11 reads out the page document B of the page specified in step S1 from the storage device 16 and converts it into the display data C. , Stored in the RAM 13 (step S
3).

Subsequently, the CPU 11 determines the attribute of each record in the display data C stored in the RAM 13 (step S4), and stores the actual data contained in each record by classifying them by attribute. Then, an attribute page object E is generated (step S5).

Here, the CPU 11 determines whether or not the process of generating the attribute page object E for the page specified in step S1 has been completed (step S6). Is completed, the process proceeds to step S7.

On the other hand, in step S2, step S
The attribute page object E of the page specified in 1 is already in RAM
13 is determined to be stored in step S13, the process proceeds to step S7.

In step S7, a display format is selected and designated by an instruction input from the input device 12. That is,
In step S7, "designated attribute display" for displaying only the designated attribute among the contents of the page designated in step S1
"Page time display" for displaying the contents of a specified page for each attribute within a predetermined time, and "displaying the contents of a specified page for each attribute according to the data amount of each attribute." A predetermined display format is selected from the three display formats "display by data amount". The display format that can be selected and designated in step S7 is the display format set in the display format setting table (FIG. 4). In the process of step S7, the display format setting table (FIG. 4) is set. The contents may be displayed on the display device 14 and shown to the user.

If "specified attribute display" is selected in step S7, if an attribute to be displayed in a page to be displayed is specified by an instruction input from the input device 12 (step S8), the CPU 11 Reads out the display data of the designated attribute such as the character attribute display data F and the image attribute display data G from the attribute page object E stored in the RAM 13 (step S9), and reads the read display data. The image is developed on the display screen memory D in the RAM 13 (step S10). Then, it is determined whether or not all the display data of the attribute specified in step S8 has been read (step S11). If all the display data has been completed, the process proceeds to step S12.
Return to 9.

In step S12, when a plurality of attributes are specified in step S8, it is determined whether or not any of the plurality of attributes has not been processed yet. Then, for all the attributes specified in step S8, if the processes in steps S9 to S11 have been performed, the process proceeds to step S13, and if there are any attributes that have not been processed, the process returns to step S8.

In step S13, the page specified in step S1 is displayed on the display device 14 based on the data drawn and developed in the display screen memory D, and the process is terminated.

If "page time display" is selected and designated as the display format in step S7, the CPU
11 resets the count value of the time counter in the RAM 13 (step S14). Then, when the attribute to be displayed preferentially is designated by the CPU 11 (step S15), the CPU 11 reads out the display data of the designated attribute from the attribute page object E (step S16), and expands the data on the display screen memory D. (Step S1
7).

In step S15, the order in which the attributes are specified may be stored in the storage device 16 in advance, and the attributes may be specified by the CPU 11 according to the order, or the input device It is also possible to adopt a configuration specified by the user by inputting an instruction from the user 12.

Thereafter, the CPU 11 determines whether or not all display data of the specified attribute has been read from the attribute page object E (step S18). Proceeding to step S19, if there is display data that has not been read,
It returns to step S16.

In step S19, referring to the count value of the time counter in the RAM 13, it is determined whether or not this count value exceeds the time limit set in the display format setting table (FIG. 4). Here, if the time limit has not been exceeded, the process returns to step S15. If the time limit has been exceeded, the process proceeds to step S13, where the display by the display device 14 is executed.

If it is determined in step S7 that "display by data amount" is selected and designated as the display format, the flow shifts to step S20 (FIG. 6), where each of the contents included in the content of the page designated in step S1 is included. Recognize the amount of attribute data. Thereafter, the CPU 11 refers to the state of the "high-speed display flag" set in the display format setting table (FIG. 4) (step S21). If the flag is set to ON, the process proceeds to step S22 and proceeds to step S22. Among the attributes whose data amount is recognized in S20, an attribute having a small data amount is designated.
Then, the display data having the designated attribute is read from the attribute page object E stored in the RAM 13 (step S23), and the read display data is read from the RAM 13
(Step S2)
4).

Here, the CPU 11 determines whether or not all the display data of the designated attribute has been read (step S25).
Then, if there is data that has not been read yet, the process returns to step S23. In step S26, it is determined whether or not a predetermined number of attributes have been specified. If the number of specified attributes is less than the predetermined number, the process returns to step S22. If it has reached, the process proceeds to step S13 (FIG. 5), the display is executed by the display device 14, and the process ends.

If the setting of the "high-speed display flag" in the display format setting table (FIG. 4) is OFF in step S21, the CPU 11 proceeds to step S21.
The process proceeds to S27, and among the attributes whose data amount has been recognized in step S20, an attribute having a large data amount is designated.

Then, the CPU 11 reads the display data of the designated attribute from the attribute page object E (step S28), and renders the read display data on the display screen memory D (step S29).

Here, the CPU 11 determines whether or not all the display data of the designated attribute has been read out (step S30). If all the display data has been read out, the process proceeds to step S31, and the data is still read out. If there is no display data, the process returns to step S28. In step S31,
It is determined whether a predetermined number of attributes has been specified or not. If the number of specified attributes is less than the predetermined number, the process returns to step S27, and the number of specified attributes has reached the predetermined number. In this case, the process proceeds to step S13 (FIG. 5), and the display is executed by the display device 14, and then the process is terminated.

FIG. 7 is a flowchart showing a multi-page display process executed by the computer system 1.
The multi-page display process shown in FIG. 7 is a process executed when a plurality of pages are designated as objects to be displayed by input of an instruction from the input device 12.

When a plurality of pages are designated as pages to be displayed by inputting an instruction from the input device 12 (step S5).
1), the CPU 11 determines whether or not the attribute page objects E for all the designated pages are stored in the RAM 13 (step S52). Here, when the attribute page objects E for all the designated pages are not stored, the CPU 11 stores the missing attribute classification data by the same processing as the above-described steps S3 to S6 (FIG. 5). It is generated and stored in the RAM 13 (step S53), and the process proceeds to step S54. Also, attribute page objects E for all designated pages are
If it is stored in the AM 13, step S52
Then, control goes to a step S54.

In step S54, the CPU 11 divides the time limit set in the display format setting table (FIG. 4) stored in the storage device 16 by the number of pages designated in step S51, and Calculate time limit of RAM
13 is stored. Thereafter, a predetermined page is designated as a processing target among the pages specified in step S51 (step S55), and the count value of a time counter provided in the RAM 13 is reset (step S56).

Then, a predetermined attribute of the page specified in step S55 is specified (step S57), display data of this attribute is read from the attribute page object E (step S58), and the read display data is stored in the RAM.
13 in the display screen memory D (step 5
9).

In step S57, as in step S15 (FIG. 5), the order in which the attributes are specified is stored in the storage device 16 in advance, and the attributes are specified by the CPU 11 in accordance with this order. Or a configuration specified by the user by inputting an instruction from the input device 12.

Here, the CPU 11 determines whether or not all the display data of the attribute specified in step S57 has been read (step S60). If all the display data has been read, the process proceeds to step S61, and the CPU 11 proceeds to step S61. If there is data that has not been read, the process returns to step S58.

In step S61, it is determined whether or not the count value of the time counter in the RAM 13 has exceeded the time limit calculated in step S54. If it has, the process proceeds to step S62, and if not, the process proceeds to step S62. Step S
Returning to step 57, the attribute to be processed next is specified.

In step S62, it is determined whether or not the processing has been completed for all the pages specified in step S51.
Returning to step 5, if all pages have been processed, step S6
Then, the process proceeds to 3, and each page is displayed based on the data developed in the display screen memory D of the RAM 13, and the process is terminated.

FIG. 8 is a diagram showing a document display screen 100 as an example of a screen displayed in the single page display processing shown in FIGS. 5 and 6 and the multiple page display processing shown in FIG. On this document display screen 100,
A bar-shaped splitter 101 that divides a document display screen 100 into right and left, and a tree display unit 1 that tree-displays a page document B of each page created by various applications such as a word processor or a presentation program.
02, and an overview display unit 103 for displaying the contents of the page document B specified in the page documents B displayed on the tree display unit 102.

Here, in the tree display section 102, folders are displayed for each application that has created a document, and the documents created by the application are displayed in a tree as subfolders. Further, in the subfolder of each document, a page document B indicating each page of the document is displayed as a tree.

The overview display section 103 displays an overview of a page selected and designated by the user. For example, the overview display unit 10 of the document display screen 100 shown in FIG.
3 displays a character attribute display window 104a in which only character attributes of a predetermined page are displayed, and an all attribute display window 104b in which all attributes are displayed.

Therefore, the user selects and specifies the file displayed on the tree display unit 102 by, for example, dragging and dropping the mouse of the input device 12 and specifies the attribute to be displayed, thereby selecting and specifying the page document. The content of B can be displayed on the overview display unit 103.

As described above, according to the computer system 1 as an embodiment to which the present invention is applied, in the display processing for displaying the contents of a predetermined page of a document created by various applications, the designated page is displayed. The page document B is read from the storage device 16, the page document B is converted into the display data C, and the actual data included in the converted record of the display data C is stored for each attribute, thereby forming the attribute page object. E is generated and stored in the RAM 13, and the attribute page object E
Among the display data, the display data of the designated attribute, such as the character attribute display data F and the image attribute display data G, is read out, drawn and developed on the display screen memory D of the RAM 13, and displayed by the display device 14. Let it. As a result, only the attributes that can be displayed at high speed, such as character attribute data, are displayed in the designated page, so that it can be used in a much shorter time than when displaying all attribute data. It is possible to give only an outline to the user. Therefore, since only the outline of the designated page is displayed in a short time, work efficiency can be greatly improved.

Further, according to the computer system 1 of the above embodiment, the attribute to be displayed as the outline of the specified page document B can be specified. To display only the image attribute.
As a result, various page documents B can be displayed according to the content of each page document B, and the work efficiency can be further improved.

Further, display data is stored in a RAM for each attribute.
