Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document editing device,
In particular, the present invention relates to a document editing apparatus and a document display method having a function of editing a document including a sentence and a chart and displaying the edited document on a screen.

[0002]

2. Description of the Related Art Generally, a document handled by a document editing apparatus is composed of parts such as a sentence consisting of character strings, mathematical expressions, charts and the like. Here, the part of the character string consisting of sentences and mathematical expressions is referred to as text. Normally, a text editing device handles text and charts separately due to the difference in data properties, and inserts the chart referenced in the text into a specified place in the text and displays it on the screen or on paper as necessary. It is being printed (report by IPSJ research group,
Document processing and human interface 20-3, September 8, 1988).

However, in the case of a document printed on paper as the final output, the place where the reference chart is inserted is limited by various conditions such as the size of the paper, the flow of text, and the size of the chart. Therefore, even in the case of the WYSIWYG display system, the reference chart is not always arranged on the same page as the portion related to the text, and thus there is a problem that it is difficult to read.

In order to cope with such a problem, for example, conventionally, information on a reference relation is given between constituent elements such as chapters, sections, figures, and tables constituting a document, and the document is constructed based on the information on the reference relation. It has been proposed that the elements be traced to enable the reference to the closely related elements (Nikkei Byte, 1987, 1).
January issue pp153-157-Hypercard: HyperC
ard, or IPSJ research group report May 1990 2
5th Multimedia communication and distributed processing 45-15).

In Japanese Patent Laid-Open No. 1-196659, information for associating a specific word in a text with a chart or the like is added, and the specific word displayed on the screen is designated by a pointing device or the like. Proposes to display a chart near the specific word in the displayed text, which allows the text and the chart that are closely related to each other to be seen on the screen at the same time.

[0006]

However, according to the above-mentioned conventional technique, in order to simultaneously display the chart related to the displayed text on the screen, the reference chart is read while reading the document displayed on the screen. When I find out something, I have to operate a pointing device etc. to give an instruction to display the reference chart, so that the instruction operation is troublesome and the operation of reading the document is temporarily interrupted, so it is difficult to read. There is a problem.

Further, since the reference chart is inserted and displayed in the displayed text, the display amount (information amount) of the text is limited. Especially, when there are a plurality of reference charts, the displayed amount of the displayed text becomes extremely small, and the description content may not be understood.

An object of the present invention is to provide a document editing apparatus and a document display method thereof which can automatically display a reference chart related to the displayed text without limiting the display amount of the text.

[0009]

In order to achieve the above object, the document display method of the present invention is a description in which a text and a figure are displayed separately in different areas of the screen and the figure is referred to in the text. It is characterized by detecting a copy and displaying the reference chart in the chart display area of the screen.

Further, the document editing apparatus of the present invention reads out and displays a memory in which text data and figure data forming a document are stored, text designated by a display command and text data and figure data corresponding to the figure. Display control means for displaying on the screen is provided, and the display control means displays the text and the chart respectively in the first and second display areas that are set separately on the display screen, and displays them in the second display area. It is characterized in that interlocking display means is provided for changing the display command so as to match the chart referred to in the text displayed in the first display area.

Here, the interlocking display means is a reference chart detecting means for detecting the presence or absence of the chart referred to in the description of the text displayed in the first display area, and the reference chart detecting means. It may be configured to include interlocking control means for outputting a command for displaying the reference chart in the second display area to the display control means. On the contrary, a command to detect the description portion of the text referring to the chart displayed in the second display area and the text including at least the detected description portion are displayed in the first display area. It is also possible to include an interlocking control means for outputting a command to the display control means.

Further, a reference symbol for identifying the reference chart is added to the text data in the vicinity of the position of the description referring to the chart in the text, and the reference chart detecting means determines whether or not the reference chart exists. Is preferably detected. According to this, it is possible to easily and quickly detect the presence or absence of the reference chart in the text.

The display control means displays a plurality of charts in a window display so as to be superimposed on each other and displays the charts in the second display area, and the reference chart window according to the description before the cursor displayed in the first display area. Is preferably displayed on the foreground.

[0014]

According to the above solving means, the object of the present invention can be achieved by the following actions. The interlocking display means automatically interlocks and displays the chart referenced in the display text on the screen. Thus, for example, even if the user scrolls the display of the text, the reference chart related to the scrolled text is automatically displayed, so that the user can read the document without being disturbed.

Since the reference chart display area is provided in a separate area on the same screen as the text display area,
The reference chart to be displayed does not limit the display amount of text, which makes the document easier to read.

Further, as will be described later, the display control means of the text editing section 1 and the chart editing section 5 respectively independently displays the text and the chart in windows which are separately displayed without overlapping on the same screen, Moreover, it is formed so as to perform display control.

Next, the text data of the present invention will be described before describing the configuration of the portion related to the characteristic portion of the present invention. As shown in FIG. 2, a reference numeral (hereinafter, referred to as an anchor) 12 for associating the description and the reference chart with a description part that refers to the chart in the text data 11 12
Is added to the text data 11. For example, when the text data 11 has a description such as "... is as shown in FIG. 2", "<FIG. 2>" is added as an anchor 12 to the end of the sentence. This anchor 12 is latent data on the display, and is not displayed or printed on the screen.
Not limited to the example of FIG. 2, the anchor 12 may be any code as long as it indicates one point in the vicinity of the description of the reference chart in the text and can identify the reference chart. The method of adding the anchor 12 is that the user adds the anchor 12 to the text data via the input unit 3 when creating the document, and
In addition to registering the correspondence between 2 and the chart, the text editing unit 1 identifies the description related to the chart in the text and adds it to the anchor 12 at a predetermined position in the text data. Correspondence can be registered automatically.

The interlocking display means for interlockingly displaying the text and the figure by using the text data to which the anchor 12 is added will be described. In FIG. 1, the interlocking display means is an anchor detection section 6 which is a reference code detection means,
Anchor information management unit 7, interlocking control unit 8, interlocking instruction unit 9
It is configured to include. First, when the user inputs a text display command, the text editing unit 1 reads the text data corresponding to the request from the memory 4a via the anchor detection unit 6 and displays the text on the screen. At this time, the anchor detection unit 6 determines the presence or absence of the anchor 12 in the display text, and outputs the detection information of the anchor 12 to the anchor information management unit 7. The anchor information management unit 7 manages the next anchor information.

Anchor in display text (display anchor) -Anchor of newly displayed chart (anchor of new display chart) -Anchor in display text for which corresponding chart is not displayed (chart Anchor disappeared from the display text due to the change of the display text (disappeared anchor) -Anchor appearing in the display text due to the change of the display text (new display anchor)
Anchor located before the cursor and closest to the cursor (anchor immediately before the cursor) The anchor information “anchor of newly displayed chart” of the anchor information management unit 7 is updated by the chart editing unit 5. To be done. The anchor information “disappeared anchor” is detected and updated by the text editing unit 1. In response to the request for interlocking display, the interlocking control unit 8 retrieves anchor information from the anchor information management unit 8, retrieves the display status information of the chart from the chart editing unit 5, and interlocks the interlocking instruction set in the interlocking instruction unit 9. A control command for interlocking display is output to the chart editing unit 5 or the text editing unit 1 according to the display method. In the interlocking instruction section 9, the necessity of interlocking display and the interlocking display method of the later-described tables and texts are set.

Hereinafter, the detailed structure of the above-mentioned characteristic portion will be described together with its operation with reference to FIGS.

FIG. 3 shows an operation procedure of the document editing apparatus when a text or graphic display command is input. First, the operation in the case of displaying the reference chart automatically in conjunction with the text display will be described. When a text display command is input by the user from the input / output unit 3 (step S1), the display control means of the text editing unit 1 operates to read the text data of the text according to the display command from the memory 4a, as shown in FIG. The text is displayed in the text window 22 of the display screen 21 shown in A) (step S2). At that time, if the presence, position, and code of the anchor 12 (a, b, ...) Are detected from the text data displayed by the anchor detection unit 6, the anchor information management unit 7
Updates the anchor information based on the detected data (step S3).

FIG. 4 shows a processing procedure of the anchor information management unit 7. Based on the data input from the anchor detection unit 6, it is determined whether the anchor 12 appears in the display text (step S11). When it is determined that the anchor appears, the detected anchor 12 is registered as the "display anchor", the "new display anchor", and the "hidden chart non-display", respectively (steps S12, 13, 14). After this registration or when it is determined that the anchor has appeared, whether or not the anchor has disappeared from the displayed text is determined based on the "lost anchor" data transferred from the text editing unit 1 (step S15). If the anchor has disappeared, the deleted anchor is deleted from the registered "display anchor" (step S16). When there is no disappeared anchor in the determination in step S15, and after the processing in step S16, it is determined whether or not there are anchors that are being displayed before and after the change of the display text, and a positive anchor "new display" is displayed. Erase from "anchor" (step S17). If the determination in step S15 is negative, or after the new display anchor has been deleted, it is determined whether or not the cursor has moved (step S19). That is, as shown in FIG.
It is determined whether or not the position of the cursor 13 displayed in the display text has moved. In general, the cursor 13 is often pointing to the part where the user is gazing, so that the overlapping of a plurality of windows for displaying the chart is changed according to the position of the cursor, as described later. The position of the cursor 13 is detected by the text editing unit 1, and the detected information is transferred to the anchor information management unit 7. If it is determined in step S19 that the cursor has moved, the anchor 12 closest to the cursor 13 among the anchors 12 in the description before the cursor 13 is updated as the "anchor immediately before the cursor" (step S2).
0). According to the example of FIG. 9A, <FIG. 3> of the anchor 12b is registered as the anchor immediately before the cursor.

After the anchor information updating process is completed, in step S4 of FIG. 3, the interlocking control unit 8 executes the interlocking process of the text and the diagram according to the setting contents of the interlocking instruction unit 9. The interlocking process in this case is executed by the interlocking controller 8 according to the procedure shown in FIG. That is, in step S21, the anchor information of the anchor information management unit 7 is referenced, and if there is a new display anchor, a display command for interlocking display of the chart corresponding to the anchor is output to the display control means of the chart editing unit 5. (Step 23). Thereby, for example, FIG.
Anchor 12 present in the displayed text, as shown in
"Fig. 2" and "Fig. 3" corresponding to a and 12b are displayed in the chart windows 23a and 23b. Chart window 23
Are assigned to each chart. When a plurality of chart windows 23 are displayed, they may be displayed in an overlapping manner as shown in FIG. 9 (A) or may be displayed so as not to overlap as shown in FIG. 9 (B). Further, when a plurality of chart windows 23 are displayed, a chart (FIG. 9) corresponding to “anchor immediately before cursor” is displayed based on anchor information.
In the case of (A), it is preferable to display "FIG. 3") at the frontmost position. The processing procedure of the interlocked display control in this case is shown in steps S41 to S43 of FIG.

Next, the display text is scrolled and the anchor 12a disappears as shown in FIGS.
When the anchor 12c newly appears, the change is registered in the anchor information management unit 7. As a result, step S in FIG.
At 24 and 25, the chart ("FIG. 2") corresponding to the disappeared anchor is hidden, and the procedure returns to steps S22 and 23 to newly display the chart ("FIG. 4") corresponding to the newly displayed anchor. . FIG. 10A to FIG. 10E show how scrolling the text display changes the display of the chart in conjunction with the scrolling. FIG. 3A shows a case where the text being displayed does not have a reference chart description. In FIGS. 6B to 6D, since the anchor 12c appears by scrolling, the chart "FIG. 4" corresponding to the anchor 12c is displayed in conjunction with each other. Then, FIG. 6E shows that the anchor “12c” disappears due to the scrolling, and in conjunction with this, the chart “FIG. 4” is hidden. In addition, FIG.
As shown in (A) and (B), when the cursor 13 is moved, the overlapping relationship between the chart windows 23c and 23d is also changed depending on the positional relationship between the anchors 12c and 12d and the cursor 13.

The operation of automatically displaying the reference chart in conjunction with the text display has been described above. Next, the description portion of the text referring to the display chart is automatically scrolled in conjunction with the display chart. The operation of displaying will be described. In this case, as shown in the flowchart of FIG.
When the user inputs a graphic display command from the input / output unit 3 (step S7), the display control means of the graphic editing unit 5 operates to read the graphic data of the graphic corresponding to the display command from the memory 4b, and the display data of FIG. The designated chart, for example, "FIG. 4" is displayed in the chart window 23c in the chart display area of the display screen 21. Next, in step S9 of FIG. 3, the anchor information management unit 7 takes in information from the text editing unit 1 whether or not the anchor corresponding to the displayed chart is displayed, and registers the result as anchor information. Specifically, as shown in the flowchart of FIG.
If the anchor corresponding to the chart displayed in the determination in step S51 is not displayed in the display text,
In step S52, it is registered as "anchor of new display chart". Then, returning to step S4 in FIG.
Executes the processing shown in FIG. That is, in step S31, the anchor information of the anchor information management unit 7 is referred to,
When there is "anchor of new display chart", a command to scroll the text so that the description corresponding to the anchor is displayed is output to the text editing unit 1 (step S3).
3). As a result, for example, when the chart "FIG. 4" is newly displayed as shown in FIG. 12B from the state in which the chart is not displayed as shown in FIG. The displayed text is scrolled so that the description part of the text referring to, that is, the anchor 12c corresponding to the chart appears in the center of the text window 22.
Similarly, as shown in FIG. 7C, when "FIG. 5" of the chart is displayed in response to the display command, the anchor 12d corresponding to the chart appears in the center of the text window 22 so that the display text is displayed. Is scrolled. In this state, even if the display of "FIG. 4" and "FIG. 5" is erased by the display instruction of the user, the display of the text window 22 is maintained as it is.

As described above, according to the processing shown in FIG. 3, the chart is displayed in conjunction with the display text,
Also, the text can be displayed in conjunction with the display chart. Further, according to the processing of FIG. 3, both linked display methods can be linked by the processing of step S5. That is, after one of the interlocked displays is executed, it is determined in step S5 whether or not the interlocked display has been executed.
The process returns to step S4 via 9 to perform a process of interlockingly displaying the text in accordance with the interlocked display chart. If the text is displayed in conjunction with the display chart in the determination in step S5, the process returns to step 4 via step S3, and the chart is displayed in conjunction with the interlocked display text. If there is no interlocking in the determination in step S5, the process proceeds to step S6 and returns to the input waiting by the user.

According to the above-described embodiment, the anchor detection unit 6, the anchor information management unit 7, the interlocking control unit 8, and the interlocking instruction unit 9 are provided.
The table referred to in the display text is automatically linked and displayed on the screen by the linked display means. Thus, for example, even if the user scrolls the display of the text, the reference chart related to the scrolled text is automatically displayed, so that the user can read the document without being disturbed. Further, conversely, since the description part of the text related to the displayed chart is automatically scrolled and displayed on the screen, the related explanation can be easily searched based on the chart. .

Since the reference chart display area is provided in a separate area on the same screen as the text display area,
The reference chart to be displayed does not limit the display amount of text, which makes the document easier to read.

In the above embodiment, the interlocked display is provided with all of the case where the related chart is displayed from the text, the case where the related text is displayed from the chart, and the case where the overlapping display of the display chart is interlocked with the movement of the cursor. However, the present invention is not limited to this, and
