Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Field of Application) The present invention relates to a document editing device for editing a compound document in which text composed of character strings and graphics are mixed.

(Prior Art) Word processors have become popular as text creation devices, and CAD (Computer
A! ded Deslgn ) is often used.

(Problems to be solved by the invention) Among word processors, there are few that can create documents containing a mixture of figures, and even if they can, there is no function to edit them all at once, making editing operations complicated and difficult to use. The problem was that it was bad.

In addition, CAD has a function to make fine copies of drawings,
Although it is excellent at creating graphics, it has a problem in that it is difficult to input and edit text like a word processor.

This invention was made in order to solve the above problems, and provides a document editing device that can easily edit a compound document containing a mixture of text and figures using operations similar to hand-proofreading on paper. The purpose is to

[Structure of the invention]

(Means for Solving the Problems) The present invention includes a document buffer that stores text data and graphic data to be edited, and a display control unit that reads data from the document buffer and displays the text and graphics on a display device. an input device that inputs calibration symbol data by hand in association with the display position coordinates of the display device; an input control unit that stores the input calibration symbol data in a graphic buffer; and a figure recognition unit that reads out the data in the document buffer and the figure recognition unit, calculates the distance between the text and figures and the trajectory of the proofreading symbol, and identifies figures and characters in the vicinity of the proofreading symbol trajectory. a neighborhood pattern search section that assigns a code; an operation estimation section that estimates editing contents of text and graphics based on the figure recognition result of the figure recognition section and the identification code of the neighborhood pattern search section; and an estimation by the operation estimation section. The present invention is characterized by comprising an editing processing section that edits graphic data and text data in the document buffer according to the results.

(Function) In the present invention, text data and graphic data from a document buffer are read out and displayed on a display device, and when a proof symbol is input by hand while looking at the display screen, the input control unit records the trajectory of the proof symbol. The coordinate data represented is stored in the figure buffer, the figure recognition section recognizes the proofing symbol according to this, and the neighborhood pattern search section calculates the distance between the text and figure and the proofing symbol and finds nearby characters. When an identification code is given to a figure and a figure, the operation estimation unit estimates the editing contents of the text and figure, and then the editing processing unit edits the figure data and text data in the document buffer. You can easily edit a compound document containing a mixture of documents using the same operations as hand-proofing it on paper.

(Embodiment) FIG. 1 is a block diagram showing the configuration of an embodiment of the present invention. The document data edited in the same figure, that is,
One-summer document data containing a mixture of text and graphics is stored in a document buffer 1, and a display control section 2 displays the document on a CRT 3 serving as a display device. On the other hand, a tablet 4 with a stylus pen (not shown) 6 is provided as an input device for giving editing instructions for this document.
Calibration symbol data can be entered by hand in association with the display position coordinates of RT3. An input control section 6 is connected to the tablet 4, which reads coordinate data representing the locus of the calibration symbol and stores it in the graphic buffer 5. In this case, since the coordinate data of the graphic buffer 5 is also given to the display control unit 2, the calibration symbol is also displayed on the CRT 3. In addition, the figure recognition unit 7 recognizes what kind of proofreading symbol it is from the coordinate data in the figure buffer 5, and compares the data in the figure buffer 5 with the data in the document buffer 1 to determine the locus of the proofreading symbol, the text, and the like. A neighborhood pattern search unit 8 is provided which calculates the distance between figures and assigns identification codes to neighboring figures and characters.

Furthermore, an operation estimation section 9 estimates the editing content based on the recognition result of the figure recognition section 7 and the identification code of the neighborhood pattern search section 8; It also includes an editing processing section 10 that edits graphic data.

The operation of this embodiment configured as described above will be explained according to the flowchart of FIG. 2.

First, data of a document to be edited, that is, a compound document consisting of sentences and figures, is stored in a document buffer 1.
This compound document is displayed on the CRT 3 by the display control section 2. In order to edit the displayed document in this state, in step]01, when the calibration symbol data is manually entered from the tablet 4 using a stylus pen, the calibration symbol is displayed superimposed on the document on the CRT 3. Also,
In step 102, the figure recognition unit 7 reads the coordinate data representing the locus of the calibration symbol stored in the figure buffer 5 and recognizes the figure shape, and at the same time, in step 103, the neighborhood pattern search unit 8 The coordinate data is compared with the text data and figure data in the document buffer 1, the distances between the proofreading symbol locus and the text and figure are calculated, and identification codes are given to the characters and figures closest to the proofreading symbol locus. This is done to limit the search range and shorten the processing time. Next, step 1
At step 04, the operation estimation section 9 estimates the editing content intended by the operator based on the recognition result of the figure recognition section 7 and the identification code of the neighborhood pattern search section 8. Therefore, editing processing section 1
0 edits the text data and graphic data in the document buffer 1 in step 105, and the display control unit 2 displays the editing results in step 106. At this time, the display control unit 2 erases the calibration symbol based on the data in the graphic buffer 5.

Next, in order to better understand this embodiment, a detailed editing operation will be explained using a specific document and proofing symbol.

Figure 3 shows proofreading symbols that give editing instructions, respectively.
a) represents a "nail J", (b) represents a "make", (c) represents a "deletion J", (d) represents a "replacement", and (e) represents a "movement of character strings and figures".

Now, consider the case where the text shown in FIG. 4(a) is edited using the "replace" symbol shown in FIG. 3(d). The text data in this case is stored in the document buffer 1, and the display control section 2 displays this text on the CRT 3. When the operator uses the tablet 4 to input the symbol T1 for "swap" by hand, the coordinate data representing the trajectory is stored in the graphic buffer 5, and the display control unit 2 inputs the symbol T1 by handwriting.
This is displayed over the text in order to be displayed on RT3. The figure recognition unit 7 recognizes this as an "exchange" symbol with a starting point P, an ending point P6, and an intermediate point P2, P3, P4, and P5. Neighboring pattern search unit 8 has 4 points P
1. A rectangle surrounded by P2, P3, and P4, and 4 points P3,
Search document buffer 1 for characters inside the rectangle surrounded by P4, P5, and P6, and select "symbol" and "handwritten"
Add an identification code to the character string. The operation estimation unit 9 estimates that the output of the figure recognition unit 7 is a swapping symbol, and since the pattern given the identification number n by the neighborhood pattern search unit 8 is a character string, it is a character string swapping operation. do. The editing processing unit 10 takes out the text shown in FIG. 4(a) stored in the document buffer 1 and rearranges the character strings.

Therefore, the display control unit 2 changes the display to the text shown in FIG. 4(b).

Next, as another example, the operation for editing the layout by moving the positions of figures and character strings will be explained using the "move character string and figure" symbol in FIG. 3(C).

As shown in FIG. 5(a), a document consisting of two rectangles B1, 81 line segments L1 to L3, and a character string C1 is stored in the document buffer 1 and displayed on the CRT 3 by the display control unit 2. do. Here, the operator inputs into the tablet 4 a handwritten figure T2 indicating a pattern to be moved. When the handwritten figure T2 is input, the coordinate data of its trajectory is stored in the figure buffer 5, and the display control section 2 displays this figure on the CRT 3 and superimposes it on the original document. The figure recognition unit 7 recognizes that the handwritten figure T2 is a "circle" because the starting point P7 and the ending point P8 are close to each other and the handwritten figure T2 forms a loop. On the other hand, the neighboring pattern search unit 8 searches the document buffer 1 for a pattern inside the handwritten figure T2. In this example, identification codes are given to rectangle B2, line segment L3, and character string C1. At this time, since the line segment L2 is a pattern that spans the inside and outside of the handwritten figure T2, it is given an identification code different from the one described above.

Since the output of the figure recognition unit 7 is a circle symbol and the pattern has been given an identification code by the neighborhood pattern search unit 8, the operation estimation unit 9 estimates that the pattern to be moved has been specified, and uses the above two types. The display control unit 2 changes the display color of the data in the document buffer 1 to which the identification code has been assigned, for example, and displays it on the CRT 3. At this time, the operation estimation unit 9 deletes the display contents of the graphic buffer 5, and thereby
Delete the handwritten figure T2 displayed on RT3.

Subsequently, when the handwritten figure T3 is inputted by the tablet 4, its coordinate data is stored in the figure buffer 5 via the input control unit 6, and the coordinate data of the handwritten figure T3 is stored in the figure buffer 5 via the display control unit 2.
Display on T3.

Here, the figure recognition unit 7 recognizes that it is a straight line whose end point is P9 and whose starting point is Plo. The neighborhood pattern search unit 8 searches the document buffer 1 for neighborhood patterns of the handwritten figure T3, but in this example, there is no pattern to which an identification code is attached.

Since the output from the figure recognition unit 7 is a straight line symbol and a movement target pattern has already been designated, the operation estimation unit 9 estimates that it is a movement operation. Since the handwritten figure T3 was written downward, the movement direction is vertically downward in the drawing, and the movement distance is 2 points P9. Let it be the distance between PIOs.

The editing processing unit 10 calculates the coordinates of the rectangle B2, the line segment L3, and the character string C1 to be moved in parallel by the amount of movement,
Write to document buffer 1. Since the line segment L2 is assigned a different identification code, only the coordinates of the end point touching the rectangle B2 are translated in parallel, and the coordinates are similarly shifted to the document buffer 1.
write to.

Finally, the pattern after movement is displayed via the display control unit 2.
When displayed on RT3, it will look like FIG. 5(b).

In the above embodiment, a tablet whose surface is traced with a stylus pen is used as an input device, but it is also possible to apply a light pen on a CRT screen or trace the surface using a liquid crystal display device. However, it goes without saying that the same editing as described above is possible as long as the handwriting can be done in association with the display coordinates of the display device.

〔Effect of the invention〕

As is clear from the above explanation, 1. According to the present invention, by recognizing a handwritten figure, identifying the nearest characters and figures in document figure data that has already been inputted with respect to the figure, and estimating the operation intended by the operator, the figure and text are Compound documents containing a mixture of documents can be edited easily by hand-proofing them on paper using the same operations.
