The figure shows an example of a screen on which a straight line is displayed as a priority figure.
FIGS. 19A and 19B are block diagrams of a graphic selecting apparatus according to still another embodiment of the present invention. FIGS. 19A and 19B are illustrations of a graphic selecting screen in the apparatus shown in FIG. The present invention is not limited by the embodiment shown in the drawings.

In the figure selecting device 1 shown in FIG. 1, the figure data memory 2 stores a straight line α shown in FIG. 2, a rectangle β shown in FIG. 3, a square γ shown in FIG. And the relative position are stored. The input order of the figures is the order of the straight line α, the rectangle β, and the square γ, and the relative position is such that the points A and B of the line α coincide with the diagonal points of the rectangle β, and the right side of the rectangle β B and D coincide with the point on the right side of the square γ.

Based on the output of the graphic data memory 2, the display image generating unit 3 generates a composite graphic and displays it on the display 5 via the display controller 4. FIG. 5 shows a composite figure displayed on the screen.

In the process of selecting a figure, the operation of the mouse 6 by the user is interpreted by the input interpreting unit 7, data relating to the position of the cursor is created by the cursor data creating unit 8, and sent to the display image creating unit 3 and the candidate extracting unit 9. Can be

When an extraction instruction signal is sent from the input interpretation unit 7 to the candidate extraction unit 9, the candidate extraction unit 9 checks the positional relationship between each figure stored in the figure data memory 2 and the cursor, and based on the candidate function 15. A candidate figure is extracted and sent to the candidate figure memory 10. The candidate function 15 is, for example, shown in FIGS.
10 as shown in FIG candidate region G _u, G _v, is to determine whether a candidate based on whether the cursor is within the G _w. According to this, when the cursor K is at the point D as shown in FIG. 6, the straight line α is not extracted as a candidate, but the rectangle β and the square γ are extracted as candidates.

When the extraction end signal is input from the candidate output unit 9 to the tentative selection unit 11, the tentative selection unit 11 tentatively selects one of the candidate figures and outputs it to the tentatively selected figure memory 12. This tentative selection is performed based on, for example, the input order of the figures, and the rectangle β
When the square and the square γ are candidate figures, the previously input rectangle β is provisionally selected.

The display image creation unit 3 checks the candidate figure stored in the candidate figure memory 10 and the temporarily selected figure stored in the temporarily selected figure memory 12 and adds an identification mark to each of them.
For example, as shown in FIG. 6, □ a, c, b, and d are added to the four points A, C, B, and D of the rectangle β of the tentatively selected figure to be another candidate figure. Square γ has four points F, E, B, D
○ f ', e', b ', d' are added to.

Therefore, the user immediately and immediately determines that the rectangle β is the most probable candidate figure, the square γ is the next most probable candidate figure, and it is inappropriate to select the straight line α at the position of the cursor K. You can know clearly.

If the user wants to select the square γ, the user may operate the button of the mouse 6 to give a next selection instruction.
In response to the next selection instruction signal, the temporary selection unit 11 sets the candidate graphic input next to the current temporary selection graphic as a new temporary selection graphic. Therefore, the screen display on the display 5 is as follows.
As shown in FIG. In other words, □ f, e, b, d indicate that the square γ is a tentatively selected figure, and ○ a ′, c ′,
The rectangle β is indicated by b ′ and d ′ as the next candidate figure.

If the user selects the square γ, the user presses the button of the mouse 6 and inputs a selection confirmation instruction. As a result, the selection determining unit 13 determines and outputs the current temporarily selected figure as the selected figure.

If there is no desired graphic in the tentatively selected graphic and the other candidate graphic, the mouse 6 is operated to input a cancel instruction. When the cancellation signal is input or an end signal is sent from the selection deciding unit 13, the cancellation ending unit 14 resets the candidate figure memory 10, the tentative selection unit 11, and the tentatively selected figure memory 12.

As understood from the above description, according to the figure selecting apparatus 1, two or more candidate figures are displayed simultaneously,
Whether the position of the cursor K is appropriate or not can be immediately known, and a different figure can be easily selected without moving the cursor K.

Next, the figure selecting device 21 shown in FIG. 11 will be described.

In the figure selecting apparatus 21, the figure data memory 2, the candidate extracting unit 9, the candidate figure memory 10, and the candidate function 15 are the same as the corresponding components of the apparatus 1 of the embodiment, and are denoted by the same reference numerals. . Accordingly, the graphic data memory 2 stores straight lines α, rectangles β, and squares γ shown in FIGS. When the cursor is near the point D of the figure, the rectangle β and the square γ are stored in the candidate figure memory 10 as candidate figures.

The priority calculation unit 31 calculates the priority based on the priority function 30 from the positional relationship between the cursor position and the candidate graphic.

An example of the priority function 30 will be described with reference to FIGS.

For example, in the case of a straight line u, as shown in FIG.
Sub-priority 1 if the cursor is inside the rectangle diagonal to, sub-priority 2 if the cursor is within a certain distance from the line, and if there is a cursor within a certain distance from the points A and B Sub-priority 4 is set, and the sum of these sub-priorities is set as the priority of the straight line U. For example priority if there is Kasoru to P ₁ is 1, the priority if the P ₂ is 2, P ₃
If if any is priority 1 + 2 = 3, the P ₄ 2 + 4 =
Is 6, which is 1 + 2 + 4 = 7, if the P _5.

In the case of a square v, as shown in FIG. 13, sub-priority 1 if within the square v, sub-priority 2 if within a certain distance from the line, and within a certain distance from the point. If there is, the sub-priority is set to 4, and these are added to calculate the priority. Therefore, the priority if the R ₁ is 1, the priority if the R ₂ is a 2, a 1 + 2 = 3, if the R _3, R ₄
In a 2 + 4 = 6, if, if the R ₅ 1 + 2 + 4 = 7
It is.

Further, in the case of a circle w, as shown in FIG. 14, sub-priority 1 if within the circle w, sub-priority 2 if within a certain distance from the line portion, and constant vertical and horizontal directions of the line portion If it is within a certain distance from the area or the center point G, the sub-priority is set to 4, and these are added to calculate the priority. For example, a priority 1 if the cursor is Q _1, is a priority 2 if the Q _2, if the Q ₃ is 1 + 2 = 3, the priority 1 if the Q ₄
+ 4 = 5, and if the Q ₅ is 2 + 4 = 6, 1 + 2 + 4 = 7, if the Q _6.

Although details are omitted, the priority is calculated based on the straight line u, the polygon is based on the square v, and the closed curve is based on the circle w.

When the cursor K is located at the point D as shown in FIG. 15, a rectangle β and a square γ are extracted as candidate graphics, and 6 is calculated as the priority of each. Therefore,
Since the priorities are equal, the previously input rectangle β is set as the priority figure and is output to the priority figure memory 32.

The display image creation unit 23 creates a composite figure based on the figure data stored in the figure data memory 2, and
A priority figure identification mark is added. For example, as shown in FIG. 15, a rectangle β which is a priority figure is indicated by a line thicker than other figures.

When the user wants to select the square γ, the cursor K is moved as shown in FIG. That is, when the cursor K approaches the point F, the priority of the square γ becomes 6, but the priority of the rectangle β becomes 2, so that the square γ becomes the priority figure. If the cursor K is further moved as shown in FIG. 17, the priority of the straight line α becomes the highest, and the straight line α becomes the priority figure.

When the desired graphic becomes the priority graphic, it is determined as the selected graphic in the same manner as in the apparatus 1 of the embodiment. When one selected figure is determined, the candidate figure memory 10 and the like are reset.

According to the figure selecting device 21, since the priority of each figure is determined by at least two levels of sub-priority, fine and flexible priorities can be defined.
"Convenience" can be improved.

Next, FIG. 18 shows a graphic selecting apparatus 51 of still another embodiment. The figure selecting apparatus 51 has both the features of the embodiment apparatus 1 shown in FIG. 1 and the features of the embodiment apparatus 21 shown in FIG. Thus, the priorities of all the figures are calculated based on the priority function 30, and those having a certain priority or higher are extracted as candidate figures. Then, the extracted candidate figures are stored in the candidate figure memory 60, and the temporary selection section 61 first provisionally selects the one with the highest priority from among them, and sends it to the temporary selection figure memory 12. When a next selection instruction signal is given from the user, the temporarily selected figure is changed to the one with the next highest priority, and the like.

FIG. 19A shows an example of a screen obtained by the figure selecting device 51. Since the cursor K is located at the point E, the priority of the straight line α is 1, the priority of the rectangle β is 3, and the square is square. The priority of γ is 6, and these are extracted as candidate graphics.
The square γ having the highest priority is the provisionally selected figure, the rectangle β is the next candidate figure, and the straight line α is the next next figure.

FIG. 19 (b) shows another example of the screen obtained by the figure selecting device 51. Since the cursor K is at the point B,
The priority of the straight line α, rectangle β, and square γ is 6,
All are extracted as candidate figures. Then, since the priorities are the same, the straight line α becomes the tentatively selected figure, the rectangle β becomes the next candidate figure, and the square γ becomes the next next candidate figure in the input order.

According to the figure selecting device 51, the advantages of both the embodiment device 1 shown in FIG. 1 and the embodiment device 21 shown in FIG. 11 can be obtained.
