[0038]
Labels of serial numbers are indicated in ascending or descending order according to a certain rule, such as alphabets written in uppercase or lowercase, such as A, B, C,... Or a, b, c. This is a symbol added to specify a characteristic point of the graphic or the graphic.
[0039]
In the graphic drawing process shown in FIG. 3, the process waits until there is a graphic input operation by the user, and in step S1, it is determined whether a graphic input operation has been detected via the input unit 3. When a figure input operation is detected (step S1: Y), the input figure is drawn in the figure display area 21c (step S2). At this time, the drawing position with respect to the graphic display area 21c is detected (step S3), and it is determined whether the drawing position is above the graphic display area 21c (step S4).
[0040]
Here, it is determined whether or not the drawing position of the figure is above the figure display area 21c. When the figure display area 21c is vertically divided, the drawing position (display position) of the figure is The determination can be made depending on whether it is located in the upper half or the lower half. At this time, a reference point in the figure may be determined, and the determination may be made based on whether the reference point is located in the upper half of the figure display area 21c. For example, if the graphic is a line segment or a curve, the midpoint can be used as the reference point, and if the graphic is a planar graphic or a three-dimensional graphic, the center or the center of gravity can be used as the reference point.
[0041]
In step S4, if the drawing position of the graphic is located above the graphic display area 21c (step S4: Y), as shown in FIG. 4, labels A, B, and C are placed above the vertices of the triangle. (Step S5). On the other hand, if the drawing position of the figure is below the figure display area 21c (step S4: N), as shown in FIG. 5, labels A, B, and C are attached below each vertex of the triangle (step S6). ).
[0042]
In FIG. 3, the figure is drawn in step S2 and the label is attached in step S5 or step S6, but the drawing of the figure and the processing for attaching the label may be performed simultaneously. At this time, after determining the labeling position, the figure may be drawn together with the label, or the label may be added together with the drawing of the figure, and then the label position may be adjusted and displayed according to the drawing position. You may do so.
[0043]
Next, another graphic drawing process executed by the graphic display device 1 will be described with reference to FIG. In the graphic drawing process shown in FIG. 6, a process is performed in which the position of the label with respect to the feature point is adjusted and the label is added according to which region in the horizontal direction indicated by the arrow in FIG. .
[0044]
6, steps S11 to S13 are the same as steps S1 to S3 in FIG. 3, and a description thereof will be omitted.
[0045]
In step S14, it is determined whether the drawing position of the figure is on the right side of the figure display area 21c. If the figure display area 21c is divided in the horizontal direction, the drawing position of the figure is located on the right half or the left half. Can be determined based on whether the At this time, similarly to the above, the determination can be made based on whether or not the predetermined reference point in the graphic is located in half of the graphic display area 21c.
[0046]
In step S14, when the drawing position of the figure is on the right side of the figure display area 21c (step S14: Y), as shown in FIG. 7, the labels A, B, and C are labeled to the left of each vertex of the triangle. (Step S15). On the other hand, when the drawing position of the figure is on the left side of the figure display area 21c (step S14: N), as shown in FIG. 8, the labels A, B, and C are attached to the right of each vertex of the triangle (step S16). .
[0047]
Also in FIG. 6, it goes without saying that the drawing and the labeling may be performed at the same time.
[0048]
Further, the graphic drawing processing shown in FIG. 3 and another graphic drawing processing shown in FIG. 6 may be executed in combination. FIG. 9 shows a flowchart of a graphic drawing process in which the graphic drawing process of FIG. 3 and the graphic drawing process of FIG. 6 are combined. As shown in FIG. 9, in steps S21 to S26, it is determined whether the drawing position of the graphic is above the graphic display area 21c as in steps S1 to S6 in FIG. 3, and further, in steps S27 to S29. In step S14, similarly to steps S14 to S16 in FIG. 6, it is determined whether the drawing position of the graphic is on the right side of the graphic display area 21c, and the position of the label is adjusted accordingly.
[0049]
According to the first embodiment described above, it is possible to automatically adjust the position at which the feature point of the graphic is labeled according to the drawing position of the graphic.
[0050]
When a plurality of figures are drawn on the figure display area 21c, the figures may be labeled with serial numbers in ascending order or in descending order. When labeling the serial numbers in descending order, the symbols may be added so that the end of the newly input figure is always A, or Z, Y, X... Symbols may be assigned in descending order. For example, when a triangle ABC is displayed in the graphic display area 21c, as shown in FIG. 10, each vertex of a newly drawn triangle (triangle indicated by a solid line) is labeled with a serial number DEF. Alternatively, as shown in FIG. 11, the labels attached to the vertices of newly drawn triangles (triangles indicated by solid lines) are A, B, and C, and each of the triangles already displayed (triangles indicated by dotted lines) The label attached to the vertex may be shifted from A, B, C to D, E, F.
[0051]
Further, the positions to be labeled in the graphic drawing processing shown in FIGS. 3, 6, and 9 are merely examples, and are not limited to these. For example, if the drawing position of the graphic is above the graphic display area 21c, the label may be attached below the vertex, and if it is below the vertex, the label may be attached above the vertex. When the figure is on the right side of the display area 21c, it may be attached on the right side of the vertex, and when the figure is on the left side of the figure display area 21c, it may be attached on the left side of the vertex. The point is that it is only necessary to automatically adjust the labeling position in accordance with the drawing position of the graphic with respect to the graphic display area 21c and add the label.
[0052]
[Second embodiment]
Next, a second embodiment will be described.
Note that the configuration of the graphic display device according to the second embodiment is the same as that of the graphic display device 1 shown in FIGS. 1 and 2 in the first embodiment. The description and illustration are omitted, and only different functions will be described.
[0053]
The graphic display device 1 according to the second embodiment executes label position adjustment processing for adjusting the display position of a label when a graphic and a label attached to a feature point of the graphic overlap.
[0054]
Next, the operation of the second embodiment will be described with reference to FIG.
In the graphic drawing process shown in FIG. 12, the process waits until there is a graphic input operation by the user, and in step S31, it is determined whether the graphic input operation has been detected via the input unit 3. When the figure input operation is detected (step S31: Y), the inputted figure is drawn (step S32), and then, each feature point of the inputted figure is labeled (step S33).
[0055]
Then, it is determined whether or not the label attached in step S33 overlaps the graphic. Here, the determination as to whether or not the label and the graphic overlap may be made, for example, based on whether or not the line segment or curve constituting the graphic and the label overlap, or the graphic display area of the drawn graphic itself. Alternatively, the determination may be made based on whether or not the display area of the label itself labeled “overlaps”. For example, in the case shown in FIG. 13, since the label B and the side (line segment) BC overlap in the triangle ABC (graphic), it is determined that the label overlaps the graphic.
[0056]
Next, when it is determined that the label overlaps the graphic (step S33: Y), the line segment label is moved to a position that does not overlap the graphic as shown in (a) → (b) of FIG. In the case shown in FIG. 13, the position where the label B is attached is moved from (a) to (b).
[0057]
On the other hand, if the label does not overlap the figure, the display is performed as it is (step S33: N).
[0058]
According to the second embodiment, when a label is attached to a feature point of a graphic, the label can be attached so as not to overlap with a line segment or a curve constituting the graphic, and the graphic and the label can be displayed in a legible manner. .
[0059]
[Third Embodiment]
Next, a third embodiment will be described.
Since the configuration of the graphic display device according to the third embodiment is the same as that of the graphic display device 1 shown in FIGS. 1 and 2 in the first embodiment, the same components are denoted by the same reference numerals. The description and illustration are omitted, and only different functions will be described.
[0060]

[0061]
Further, when a graphic displayed on the graphic display area 21c is touched with the touch pen 3b, the graphic is selected. Further, when the selected figure is moved in a direction in which the touch pen 3b is to be moved on the display, the display position can be moved. The operation of the graphic display device 1 when adjusting the display position of the label at this time will be described with reference to FIG.
[0062]
In the label position adjustment process shown in FIG. 14, the process waits until there is a figure selection operation by the user, and in step S41, it is determined whether or not the figure selection operation has been detected via the input unit 3. When a figure selecting operation is detected (Step S41: Y), the selected figure is identified (Step S42), and the presence or absence of a figure moving operation by a touch pen operation is detected (Step S43).
[0063]
When the moving operation of the figure is not detected (step S43: N), the process returns to step S42. On the other hand, when a figure moving operation is detected (step S43: Y), it is determined whether or not the figure is moved within the figure display area 21c (step S44).
[0064]
When the moving position of the graphic by the operation of the touch pen 3b is within the graphic display area 21c (step S44: Y), the label is moved together with the moving of the graphic, and the graphic and the label are displayed at the moving position (step S45).
[0065]
On the other hand, when the graphic is moved out of the graphic display area 21c, the part moved out of the graphic display area 21c is not displayed (step S46). At this time, the label is also hidden as shown in FIG.
[0066]
Next, in step S47, it is determined whether or not this graphic has been moved again into the graphic display area 21c (step S47). When the label is moved into the graphic display area 21c again (step S47: Y), the label is displayed according to the position information of the label stored in the RAM 5 or the external storage memory 7.
[0067]
According to the third embodiment, even when a part of the graphic moves outside the graphic display area 21c, the position information of the label attached to the characteristic point located outside the graphic display area 21c and the like are stored in the RAM 5 or the external storage. Since the graphic is stored in the memory 7, the label can be displayed again when the graphic is moved into the graphic display area 21c again.
[0068]
In steps S45 and S47, the display position of the label may be adjusted according to the display position of the moved graphic with respect to the graphic display area 21c as described in the first embodiment. If the label and the graphic overlap when adjusting the display position of the label, the display position of the label may be further adjusted as described in the second embodiment. By doing so, it is possible to adjust the labeling position according to the display position of the moved figure.
[0069]
When a part of the graphic moves outside the graphic display area 21c in step S46, as shown in FIG. 16, the direction in which the feature point moved outside the graphic display area 21c is located is indicated by an arrow. A label attached to the feature point may be displayed. In this manner, even when a part of the graphic moves outside the graphic display area 21c, the direction in which the feature point is located is displayed by the arrow, so that the user can recall what the graphic is.
[0070]
It is preferable that the setting is made so that all of the graphics do not move out of the graphics display area 21c. By moving a part of the graphic to the outside of the graphic display area 21c in this manner, a new graphic input operation or a drawing operation using the touch pen 3b can be facilitated.
[0071]
