Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an edit graphic selecting system, and more particularly to an edit graphic selecting system used in a graphic editing / creating apparatus for performing a graphic editing / creating process by utilizing an arithmetic processing function or graphic processing function of a computer. .

[0002]

2. Description of the Related Art In a graphic editing / creating apparatus or the like for performing processing such as editing and creation of a graphic utilizing an arithmetic processing function and a graphic processing function of a computer, a plurality of graphics displayed on a display screen are displayed. It is common to move, copy, or delete a graphic. An example of such a conventional editing figure selection system for selecting one of a plurality of figures will be described.

FIG. 8 shows a first example of a conventional editing figure selecting system.
FIG. 9 is a diagram showing a figure or the like on a display screen for explaining the example (hereinafter also referred to as a first conventional example, the same applies to other examples).

In the first conventional example, a plurality of figures P1
1 and P12, respectively, are set with graphic range frames PF11 and PF12 indicating that they are within the graphic region. The cursor CS is moved with a mouse or the like to move the graphic range frame (PF11) of the graphic to be selected (eg, P11). Can be selected by putting it in parentheses. This system has the advantage that the load on figure selection is small because the internal processing is simple,
This is effective when the figure to be selected does not overlap another figure.

[0005] As a second conventional example, there is a "system for selecting an arbitrary figure from a plurality of figures superimposed and displayed", which is used when the coordinates of a cursor are located within the area of a plurality of figures. In order to facilitate selection of a target figure from among them, an option such as “next candidate” is provided, and when the operator inputs “next candidate”, the cursor coordinates are present in the area. Are sequentially selected as candidates for selection (see, for example, Japanese Patent Application Laid-Open No. 4-246785). FIG. 9 shows a flowchart of the second conventional example.

Further, as a third conventional example, when an arbitrary figure is selected from a multiply folded figure, a display area including a selection target figure is specified in advance, and a figure to be displayed at an arbitrary set time is specified. In some cases, a figure is selected by switching and inputting a "confirm" key when a target figure is displayed. This example has an advantage that the operation does not become complicated when a small figure is selected because the target figure can be selected without moving the cursor after the display area including the selection target figure is specified (for example, see Japanese Patent Laid-Open No. -334415). The system configuration of the third conventional example is shown in FIG.
Shown in

[0007]

In the first and second prior art examples, the above-mentioned conventional editing graphic selection system requires that the cursor be moved to the figure range frame of the graphic to be selected and determined. For this reason, it takes time to move the cursor or the like, or when a figure is very small, for example, about 1 mm square, it is difficult to accurately move the cursor within the figure range frame of the figure. In the third conventional example, the superimposed graphics are sequentially switched at set time intervals, and when the graphics to be selected are displayed, the enter key is pressed. If you select a figure, the display order of the selection target figure is slow, so that it takes time to select it.If you miss the selection target figure, it takes time until the next display There is a problem in that it takes a long time until-option, also not so in order to to need to have to increase the extremely tense missed, there is a problem that the degree of fatigue climb.

And a display device 3 for displaying a cursor CS. The cursor CS is moved to a predetermined position of a predetermined graphic (for example, P2) among the graphics (P1, P2) displayed on the display device 3, and this graphic is displayed. (P2) is selected, and the control device 4 includes a plurality of graphics (P1, P2
2) Position coordinates (PP1, PP2) indicating a predetermined position in the display area of these figures are set corresponding to each of them, and these are stored in the storage unit 43, and the coordinates of the display position of the cursor CS and the plurality of figures are displayed. (P1, P2) Each position coordinate (P
P1, PP2) and the cursor CS and a plurality of figures (P

P2) Refer to the distances between them, and, based on the result of this reference, a figure whose distance is the shortest (for example, P2)
Is controlled so that the cursor CS is automatically moved to and displayed at the position coordinate (PP2).

Next, the figure selecting operation according to the first embodiment will be described.

A plurality of graphics (P) displayed on the display screen
When a specific figure (for example, P2) is selected from (1, P2), in step S1, the position coordinates (PP1, PP2) of all the figures displayed on the screen and the position coordinates of the cursor CS are determined. The distance between the cursor CS and each of the plurality of figures is obtained and stored in the memory unit 43. In step S2, a figure (P2) having the shortest distance from the position coordinates of the cursor CS stored in the memory unit 43 is searched, and the position coordinates of the cursor CS are set to the position coordinates of the searched figure (P1). Change by 44.

Next, in step S3, the position coordinates of the cursor CS changed by the cursor movement control unit 44 are transmitted to the display device 3 via the interface 41, and the cursor CS is moved to the position of the position coordinates on the display screen. indicate.
Next, in step S4, it is determined whether a key input from the keyboard 1 or the mouse 2 has been made. If there is a key input, it is determined in step S5 whether or not the input is for the next candidate key.
Move S and return to step S1.

If it is determined in step S5 that the input is not for the next candidate key, it is determined in step S6 whether the input is for the enter key.
If not, the process returns to step S4, and if it is the decision key, in step S7, the figure (P2) of the currently displayed position coordinates of the cursor CS is decided as the selected figure.

Next, the operation when one figure is selected from the two figures P1 and P2 displayed on the display screen will be described with reference to FIG.

Before the figure selection instruction, as shown in FIG.
It is assumed that two figures P1 and P2 are displayed on the display screen and the position coordinates (X, Y) of the cursor CS are close to the figure P2. In step S1, figures P1, P
2 position coordinates PP1 (X1, Y1), PP2 (X2, Y
2) The distance between the position coordinates (X, Y) of the cursor CS is obtained.

For simplicity of description, the distance between the position coordinates PP1 (X1, Y1) of the figure P1 and the position coordinates (X, Y) of the cursor CS is represented by a line segment L1, and the position coordinates PP2 of the figure P2. The distance between (X2, Y2) and the position coordinates (X, Y) of the cursor CS will be referred to as a line segment L2.

Since the line segment L2 has the shortest distance obtained in step S2, if there is a figure selection instruction, in step S3, as shown in FIG.
The cursor CS is displayed at the position (X2, Y2), and the process waits for a key input in step S4. When the enter key is input, the graphic P2 is passed through steps S5 and S6 and step S7.
Is determined as the selected figure.

When the cursor CS is moved closer to the figure P1 while waiting for a key input in step S4, the operations of step S5, step S1, step S2, step S3, and step S4 are repeated. 3
The position of the cursor CS displayed at the position coordinates PP2 (X2, Y2) of the figure P2 is moved by the movement of the cursor as in (c), and the position coordinates PP1 (X1, Y
The position cursor CS of 1) is displayed.

Then, when the enter key is input, step S
5. After step S7, figure P1 is determined as the selected figure in step S7.

As described above, when a specific figure is selected from a plurality of figures, the distance between the position coordinates of all the figures displayed on the display screen and the position coordinates of the cursor is obtained.
When there is a figure selection instruction, the cursor moves to the figure whose distance is the shortest as the selected figure, and when the confirm key is selected, the figure is confirmed as the selected figure at that time. If the cursor movement key is selected, move the cursor on the display screen, recalculate the distance between the cursor position coordinates and the position coordinates of each figure, and select the figure with the shortest distance as the selected figure. This process is repeated until the coordinate is moved to an arbitrary coordinate of the figure and the enter key is selected. Therefore, just by moving the cursor close to the position coordinates of the graphic to be selected, even a very small graphic can be accurately and easily adjusted to the position coordinates of the selected graphic. Is shortened.

In the above example, the figure selecting operation in the case where the figures do not overlap is described. However, even when an arbitrary figure is selected from a plurality of overlapping figures, the key input step S4 of FIG. , Next candidate key step S
5 and the processing of step S6 of the confirmation key are repeated,
As in the third conventional example, it is possible to easily obtain the same effect as the graphic selecting operation in the case where the graphics do not overlap with each other without operation fatigue.

FIG. 4 is a flowchart for explaining a graphic selecting operation according to the second embodiment of the present invention, and FIG. 5 is a view showing a graphic on a display screen for explaining the graphic selecting operation.

In the second embodiment, a rectangular figure range frame (PF3, PF4) is set for each of a plurality of figures (P3, P4), and these figure range frames (PF3, P4) are set.
3, PF4) (PP31-PP34, PP41-
(PP44) The distance between the cursor CS and the shortest distance among the distances between the four corners and the cursor is stored in the memory unit 43 as the distance between the figure and the cursor. It is.

Next, a graphic selecting operation according to the second embodiment will be described.

When a specific figure (for example, P4) is selected from a plurality of figures (P3, P4) displayed on the display screen, in step S11, all the figures (P4) displayed on the display screen are selected. P3, P4) figure range frame (PF
3, PF4) (PP31-PP34, PP41-
The distance between the coordinates of PP44) and the position coordinates of the cursor CS is obtained and stored in the memory unit 43. Next, step S12
Then, the shortest distance stored in the memory unit 43 is searched for, using the shortest distance from the cursor position coordinates of the four corners obtained for each figure as the distance from the cursor of the figure, and searching the figure (P4 ) (In this example, PP
In step 41), the cursor movement control unit 44 changes the coordinates of the cursor CS position.

Thereafter, as in the first embodiment, the operations of steps S3 to S8 are executed to determine the selected figure. However, after step S8, the process returns to step S11.

On the display screen, as shown in FIG. 5A, there are a figure P3 and a figure P4, and when the figure P4 is closer to the cursor position than the figure P3 (L4 <L3), the figure is selected. When the instruction is given, as shown in FIG. 5B, since the distance L4 of the figure P4 is shorter, the position coordinates PP41 of the figure P4 are obtained.
Is moved to and displayed. And this figure P
If 4 is an object to be selected, the enter key is input to confirm the selected figure.

In the second embodiment, the distance between the figure and the cursor is the shortest distance of the figure range frame with respect to the cursor position. Therefore, as in the first embodiment, one position of the figure There is an advantage that the distance between the cursor and the figure on the display screen can be easily grasped as compared with the case where the distance between the cursor and the figure is determined by the distance between the coordinates and the cursor.

FIGS. 6 and 7 are a flow chart for explaining a graphic selecting operation according to the third embodiment of the present invention, and figures showing a graphic displayed on a display screen.

In the third embodiment, when the vertical position between the current cursor position and the graphic to be selected is far apart, the number of the line on which the graphic to be selected is displayed is designated. Then, the cursor is quickly moved to that line, and the time until the selected figure is determined is shortened.

In the third embodiment, a line number is entered in step S4 of key input in the first and second embodiments.

In FIG. 6, steps up to step S5 are the same as in the first embodiment except that a line number is input. Next, in step S14, it is determined whether or not a line number has been input. If the line number has been input, the cursor CS is moved to the input line number in step S15 (control of the cursor movement control unit 44 and the like). Originally), the process returns to step S1, and the subsequent operations are repeated. Steps S6 and S7 are the first
This is the same as the embodiment. After the operation in step S8, the process returns to step S3 with the solid line in FIG. 6, but may return to step S1 as indicated by the broken line.

In FIG. 7, when the cursor CS is displayed at the position coordinates of the figure P5 (FIG. 7A), the figure P6 is displayed to quickly move the cursor CS to the position coordinates of the figure P6. The cursor CS is moved to that line by inputting the line number of the area (FIG. 7 (B) (1)), and then the cursor CS is moved to the position coordinates of the graphic P6 (FIG. 7 (B)). (1)) is shown.

In these embodiments, when the input of the next candidate key or the movement of the cursor is made, the cursor between the figure selected immediately before these inputs (the cursor CS is displayed at the position coordinates) and the cursor is displayed. Even if the distance between them is the shortest, this figure is excluded from the selection candidates by the CPU.
42 and the like.

[0040]

As described above, according to the present invention, the position coordinates of each of a plurality of figures and the distance between the same-shaped range frame and the cursor position are calculated and stored. The cursor is moved to the position coordinate of the shortest figure among these distances. If the figure is a target to be selected, this is determined as a selected figure. If not, the next candidate key input, cursor movement input, The same operation is repeated by moving the cursor by inputting the line number, etc., and the selected figure is determined, so even if the figure is very small or the figure is superimposed, simple keys can be used. There is the effect that the selected figure can be determined accurately and easily by input and rough cursor movement, and without fatigue in operation, in a short time.
