Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a graphic editing device, and particularly to an online handwritten input graphic editing device.

More specifically, the present invention specifies a graphic segment to be edited and designates editing contents using online handwritten input graphics, and allows graphic editing to be performed by 1-1-1, which is similar to the conventional graphic editing on paper using a lead box and an eraser. The present invention relates to an online handwritten input graphic editing device that allows editing.

[Background]

2. Description of the Related Art Conventionally, when editing figures using a computer, a menu-only system has been frequently used in which a menu is displayed on a display and a desired figure is selected from the menu using a cursor.

In particular, recently, a menu-based system has been proposed in which pictures such as files, cabinets, trays, etc. are displayed on the display, and the pictures are selected using a coordinate input device.

However, with these one-sided menus, the cursor must be moved up, down, left, and right to perform editing, which moves the point of view, tends to disrupt the operator's thinking, and reduces work efficiency. There were 9 flaws.

In other words, it is much easier to operate than the traditional method of writing and erasing letters and figures on paper using a pencil eraser and eraser. Rika Ride 7r requires training and mature #I to do all the work of the 4th volume
＜However, it had the disadvantage that it was difficult to achieve efficient editing.

[Purpose of the invention]

The present invention was made in view of these drawbacks, and its purpose is to provide an easy-to-use and easy-to-use method for editing figures that is as similar as possible to the conventional figure editing method using paper and pencil. - That is, the object is to provide an online handwritten input figure editing device that has a good so-called man-to-man interface.

[Summary of the invention]

In order to achieve the above object, the present invention selects a figure segment to be edited from among various figures displayed on the screen by selecting a closed figure that intersects a part of the figure segment. , input it by hand with the stylus pen, and then input the edit command shape to specify the editing contents by hand with the stylus pen,
The feature is that these two handwritten input figures are distinguished and the specified editing contents are applied to the specified figure and then to the second figure.

According to the present invention, a frame memory for displaying figures and an image display frame memory for displaying the trajectory of the stylus pen are separately provided, and the trajectory of the stylus pen, for example, an edit command figure is displayed as an edited figure. The main feature is that it is configured so that it can be easily erased.

[Embodiments of the invention]

Hereinafter, one embodiment of the present invention will be described in detail using FIGS. 1 to 15.

FIG. 1 is a schematic block diagram of one embodiment of the present invention.

Pen amplifier down information and position coordinate information a generated by the coordinate input device (tablet) 1 and the stylus pen 12 are input to the graphic recognition processing section 310 of the graphic editing and arithmetic system 30.

The figure recognition processing unit 310 generates a figure selection window (pink window) for selecting a figure segment to be edited, based on the information aK, and discriminates an editing operation command from handwritten figure coordinates. @b appears.

If this information is used, the information f of the editing function key 4 can be used to delete the figure,
Editing such as movement, enlargement, and reduction is processed while reading data into the graphic display frame memory 330 and the image display frame memory 340.

The figure display frame memo 1J330 is configured to write figures expressed as vectors, while the image display frame memory 340 is configured to input handwritten input data t-*, thereby simplifying the figure editing process. .

Further, the contents of the graphic display frame memory and the image display frame memory are combined in a bar-by-bar manner, for example, by an OR circuit 350, and displayed in the display & box 2.

In the illustrated embodiment, a coordinate input device, that is, a tano
This system uses a so-called integrated input/display device that integrates the input and display means 1 and the display means 2, and allows handwritten figures to be input and edited in the same manner as conventional paper and display devices, and its operability is improved. (so-called man-47 interface). Next, FIG. 14 shows the graphic editing function realized in one embodiment of the present invention. As shown in the figure, editing includes processing such as erasing, moving, enlarging, reducing, rotating, and shading1. ), we use the method of enclosing one part of the quadrilateral with a gold circle and writing the handwritten editing command inside this circle. An editing command is recognized from this handwritten information, and an edited figure as shown in FIG. 14 is obtained.

For example, as illustrated in FIG.
Enter a → mark for "Move", a "<" mark for "Enlarge/Reduce", an O mark for "Rotate", and a 1 mark for "Shadow" considering the direction of the shadow.

Next, regarding the detailed structure and operation of each part in Fig. 1,
It is described below.

FIG. 2 is a detailed block diagram showing a specific configuration of the figure recognition processing section 310 shown in FIG.

Handwritten input figures with the stylus pen 12 are roughly divided into closed figures a1 for selecting figures displayed on the screen in advance, and closed figures a2 for m-set operation commands t7.
), I That is, these input figures are first identified and separated into closed figures and closed figures by the open/open figure identification processing unit 312.The 3° identification is performed by the stylus pen 12 as shown in FIG.
This can be easily done depending on whether or not the end point Q of the stroke is within a circle of a predetermined radius r around the starting point P of the 0 stroke. That is, if it is within the radius r, it is a closed figure,
If not, it is determined that the shape is open.

Note that the starting point P of the stroke is determined by the down signal of the stylus pen 12, and the end point Q is determined by the up signal. It is necessary to do so.

- Also, the squillous pen 1 read from the tablet 1
Based on the position coordinates of 2, the moving direction (vector) of the stysis pen 12 is determined by the direction code (8) shown in FIG. 3, for example.
direction) and stored in memory along with coordinate information, which serves as information for recognition.

When the closed/closed figure identification processing unit 312 recognizes that the handwritten input figure is a closed figure, the maximum and minimum values y (max) of the coordinates of this closed figure a1 in the X direction and the X direction are determined.
, y (min), x (max), x
(min), the figure pink window (hereinafter simply referred to as window) WID as shown in Fig. 5,
The figure pick window generation unit 314 generates the window and sends it to the figure editing unit 320 together with the figure to be edited.

On the other hand, the open figure is input to the editing operation command identification section 316, and an editing command COM is output.

The editing operation command COM can be determined by the procedure shown in Flowchart 1 of FIG.

That is, after performing the pre-processing, the stesoge 316-
1, the first coordinate point input is taken in. The stem game 316-2 determines whether the input coordinates are the starting point based on whether or not the pen down signal is detected. If it is the starting point, the process jumps to step 316-5, and it is determined whether processing of all input points has been completed, that is, whether a pen amplifier signal has been detected.

When the input point is determined not to be the starting point in the determination of the stesoge 316-2, a direction vector (with reference to FIG. 3) is calculated from each coordinate of the previous input point and the current input point (stesoge 316-a). .

In the next step 316-4, it is detected whether or not the same direction vector continues for a predetermined number of times.

When the same direction vector is continued multiple times as planned e'5
, proceeds to the stem game 316-4A, recognizes the vector as a directional pattern, and creates data.

If it is not determined in step 316-4 of [''I) that petals in the same direction have been continuously detected the predetermined number of times, the process jumps to step 316-5.

If it is determined in step 316-5 that no pen-up signal is detected and that all input points have not been processed, i is incremented by 1 (1+1) in step 316-6.
Then, the process returns to step 316-1.

Then, the (++i)th coordinate point of the stylus pen 12 is read and the above-described process is repeated.

That is, steps 316-1 to 316-5 to 316-
Through the loops 6 to 316-1, a direction pattern for the input figure is created as shown in FIG.

In the example of FIG. 15, for example, the direction pattern for the "erase" command is 1\1 + 6 + 1 t 6
+ 1 +6.1,6,1. E becomes. In fr, o, ko\, E indicates the end point of the direction pattern. Similarly, each of the commands ``move,''``enlarge/reduce,''``rotate,'' and ``shade'' has its own directional pattern.

Returning to the flowchart in Figure 6, if the direction pattern is not correct as described above, check it with the direction pattern defined in the dictionary in advance, find a matching pattern among them, and edit it. Output as command COM (stesoge 316-7).

As described above, in the figure recognition processing unit 310, the figure pink window WID and the editing operation command COM are
Gamaru. These data are transmitted together with the input position [Pj of the stylus Ben 1 to the figure editing section 320 in FIG. 1. A detailed block diagram of the figure editing section 320 is shown in FIG. is the graphic display processing section 32
6 will be man-powered. Based on this, the graphic display processing section 32
6 detects the segment of the graphic to be edited cut out by the graphic big window WID.

Then, among the graphics to be edited, the graphics defined to be integrated with the segments are output as edited graphics (Sefumen)G. The edited graphic segment G is transmitted to the graphic processing unit 324 at 1°, while the stylus pen 120 input coordinates Pi are
(σ) In order to display the locus, the graphic display processing unit 32
6, the data d is stored in the image display frame memory 340.
It is imported as 4i.

11 editing operation commands COM in the figure editing processing unit 324,
Graphic editing is performed using the function key information f1 and the selected fc grid graphic segment G as input data using a known method as will be described later.

The specific processing procedure of the graphic editing is shown in the flowcharts of FIGS. 8 to 12.

FIG. 8 is a flowchart 1 showing the processing procedure of the "erase" command.

- First, in order to erase the trajectory display (handwriting editing command) of the stylus pen 12, the image display frame memory 340't-clear step 581), and then the figure selected by the figure display processing section 326 in FIG. Based on the data of segment G, the corresponding data in the graphic display frame memory 330 is erased (step S82
),.

As a result, the corresponding one of the figures shown on the display device is erased (see Nα1 in FIG. 14).

When the editing end key 41 is operated, the erasing process ends.

FIG. 9 is a flowchart showing the processing procedure of the "move" command.

As in the case of Figure 8, at the beginning, image 142J
= Clear all 340 and erase the trajectory display of C1 Squillous Ben 12 from the display screen Ifi]-l) (step St+X).

Next, when the coordinates of the stylus pen 12 are moved using the entire tuplet, the selected segment follows this movement and is moved (step 592).
.

Since the collective method of moving the figure in a stiff manner is well known to those skilled in the art, its explanation will be omitted.
゜When the selected figure segment has been moved and positioned to the desired position, ? Anction L = +
When the knitting end key 41 of A is pressed down, the movement of the figure ends (step SC+3).

A specific example of this processing is shown in FIG. 13(a). In the figure, 100 is a selected editing graphic segment before processing, and 102 is a movement locus of the stylus pen 12.

FIG. 10 is a flowchart showing the processing procedure of the "enlargement/reduction" code 77.

As in the case of FIG. 8, clear the image display memo 9340 and display the trajectory of the stylus pen 12 IIll
After deleting from lImj (step 51oz), it is determined whether the function key 41 or 42 or 43 (Fig. 1) is pressed (step 5102).

If the function key -42 has been pressed down, the process proceeds to step 5103, and the selected graphic segment is enlarged in predetermined increments (magnification), as shown by reference numeral 103 in FIG. 13(b). do.

Then, the process advances to step 5105, and it is checked whether the mix completion key 41 has been operated. If it is being operated, this process ends, but if it is not being operated, t
Then, repeat steps 8102 and 8103 again to enlarge the selected graphic segment by 1L) degrees.

That is, the operator can perform graphic enlargement simply by holding down the function key -42 until the selected graphic segment is enlarged to the desired size.

If it is determined in step 5102 that the function key 43 is pressed, the process advances to step 5104. In step 5104, the first
As shown by the reference numeral 104 in Figure 3 (・''), the selected button/
This graphic segment is reduced in predetermined increments (reduction ratio) 3. Then, as in 1iiT, the process advances to step 5105 and it is determined whether the editing end key 41 has been operated. If the operation is being performed, this process ends, but if the operation is not being performed, steps 13102 and 51 are performed again.
Repeat step 04 to reduce the selected graphic segment again.

In this manner, the target graphic segments are successively reduced as long as the function key 43 is held down.

If the selected graphic segment is enlarged or reduced too much, pressing the function key 43 or 42 allows the selected graphic segment to be reduced or enlarged in predetermined steps.

Once the graphic segment has been edited to the desired size, press the editing end key 41'lc to end the process.
The procedure for reduction processing is also well known to those skilled in the art.

- There is also a function key 42 for enlarging or reducing.
Once the function key 43 is operated, the enlargement or reduction operation may be repeated at scheduled time intervals until the editing end key 41 is operated. or 43
There is no need to keep pressing .

FIG. 11 is a flowchart showing the processing procedure of the "1 rotation" command.

As in the case of moving or shrinking/enlarging as described in +jil,
Stop r1 Clear the image display memory 340 and display the trajectory of the Nutira pen 12! jDelete from page 1 (
Step 5ill). Thereafter, similarly to the enlargement/reduction processing shown in FIG. 10, it is determined in the suanop 5112 whether or not the function key 42 or 43 is pressed.

Then, depending on which 7γ adjustment key is pressed down, the process of clockwise rotation (step 511a) or counterclockwise rotation (step 5114) is performed as shown in (c) in FIG.
It is processed in predetermined increments as if it were a large scale. , kf:
At step 8115, the editing end key 41 is pressed to complete the process (step 8115).

Such graphic rotation processing techniques are also well known to those skilled in the art. Also, the processing procedure can be changed as in the case of enlargement/reduction.

FIG. 12 is a flowchart showing the processing procedure of the "shading" command for emphasizing a figure.

Similar to the case of if+statement, the image display memory 340
is cleared, and the trajectory display of the Squirluspe/12 is erased from the light display screen (step 5121). Thereafter, in step 5122, a desired shadow location is determined based on the direction of the stroke of the input graphic.

There are four corners as shading 1161 places, and FIGS. 13 and 15 show examples in which the upper right corner is shaded.

Next, in step 5123, it is determined whether the function key 42 or 43 has been pressed. Then, depending on whether Tochi's function key is pressed down,
It is determined whether the shading is to be increased or decreased, and in step 5124 or 8125, as shown in FIG. This shading process ends when the editing end key 41 is pressed (step 81).
26).

Techniques for such graphic shading and processing are well known to those skilled in the art. ′! Also, the processing procedure can be changed as in the case of enlargement/reduction.

[Transformation row]

The present invention can be implemented with the following modifications. This does not necessarily mean that there is no calligraphy in the omitted closed figure. In other words, the effect of the present invention does not change even if a handwritten trick command is input near the figure to be edited.

(2) In the previous example, the handwritten editing operation command is
3. Although the input is made using strokes, ie - brush strokes, this may be done using multiple strokes. for example,"
The effect of the present invention is the same even if "movement" is entered with two strokes like the → mark instead of with a single stroke of the pass mark.

(3) Although the above embodiment uses an integrated input and display device, the input and display devices may be separated. For example, instead of a flat display, a CRT device, which has been commonly used in the past, may be used as the display device. However, in this case, since the input and display devices are separate, it is difficult to expect much improvement in operability or man-machine performance.

(4) In the above embodiment, a dedicated function key is used, but this function key may be provided on the stylus pen. In this case, all graphics can be edited with one hand.

〔Effect of the invention〕

As is clear from the above explanation, according to the present invention, effects such as the following are achieved.

(]) Specify the shape to be edited by enclosing (cutting) a part of the shape displayed on the screen with a hand-drawn closed shape, and then specify the shape within the closed shape or near the shape to be edited. The editing type can be specified by writing the edit command shape by hand, which is similar to traditional editing on paper using a pencil and eraser, and is easier to operate than the traditional menu-based shape editing. This will improve the so-called man-machine characteristics.

Therefore, confusion in the operator's thinking is reduced, and even non-experts can easily edit without requiring any skill.

(2) When equipped with an input display integrated device, the trajectory of the stylus pen can be displayed as is, and it can be considered as an extension of the conventional paper and pencil, further improving man-machine performance.

(3) Editing processes such as enlarging, reducing, rotating, etc. of figures can be visually confirmed, making operations extremely easy. .

(4) Separately having a figure display frame memory for displaying figures expressed in vectors and an image display frame memory for displaying the trajectory of the stylus pen;
Since this is combined and displayed, it becomes extremely easy to delete the shape of the editing command from the final shape1.
