Abstract

PROBLEM TO BE SOLVED: To facilitate the operation for work in changing edition of a coordinate data sequence by resolving such problem that the number of operation steps required for editing is large and the work is apt to be complicated because the operation step where changing edition of values of single coordinate data is performed by dragging each single coordinate with a mouse or the like is conventionally repeated plural times in the case where it is necessary to perform changing edition of values of an outline coordinate data sequence in an objective part in order to deform a partial shape or the like in a picture. SOLUTION: A cursor having a cursor shape indicating an editable area of which the area size can be varied by an input means like a keyboard is displayed on an editing picture. When the cursor is moved, the values of plural coordinate data of a coordinate sequence indicating a partial area, the boundary, or the like of a display picture are made to coincide with coordinates on the outline of the editable area if this coordinate sequence is within the editable area, and thus simultaneous change editing of plural coordinate data of the picture is performed.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an industrial field where coordinate data of an image needs to be edited.
For example, the present invention relates to an editing method using input means such as a mouse or a cursor key when it is necessary to change and edit a value of a contour coordinate data series of a target portion in order to deform a partial shape in an image.

[0002]

2. Description of the Related Art Conventionally, when it is necessary to change and edit the value of a contour coordinate data series of a target partial image, for example, to deform a partial shape in the image, input means such as a mouse or a cursor key is used. Edit, change single coordinate data value.

[0003] When inputting a new image or overwriting data of an existing image, an input method is called a pen tool shape on an edit screen in advance. After setting the shape,
A method of simultaneously inputting a plurality of image data by input means such as a mouse or a cursor key may be used as a known method technique, but is not a new or overwriting data input, but a line or a line representing a contour shape of a partial image. In a line graph or the like, when a coordinate data series value once determined is changed and edited, an editing method for individual single coordinate data has been used.

[0004]

Although the editing method for individual single coordinate data can change and edit precise coordinate data, it is possible to edit a coordinate data series or a contour coordinate data series representing line information or a boundary in a line graph. When trying to change and correct the shape and the like, a plurality of coordinate data values need to be changed and corrected, so that the number of operation steps required for editing is increased and the work tends to be complicated.

An object of the present invention is to solve the above-mentioned problem, and to facilitate an operation at the time of changing and editing a once-determined coordinate data series value instead of inputting a new or overwritten image. With the goal.

[0006]

In order to achieve the above object, according to the present invention, a cursor for indicating an editable area is displayed on an edit screen, and a change and edit operation is performed by input means such as a mouse or a cursor key. The present invention is characterized in that coordinate data values to be instructed are simultaneously changed and edited for a plurality of coordinate data instead of individual single coordinate data.

[0007]

When the cursor for indicating the editable area on the edit screen is moved by input means such as a mouse or a cursor key, if the target coordinate data series is included in the editable area, the cursor is moved to the position where the editable area is included. The plurality of coordinate data values are changed to the same values as the coordinates on the outline of the editable area displayed in a cursor shape.

[0008]

The present invention will be described below in more detail with reference to examples. FIG. 1 is an example of a computer system used in an embodiment of the present invention. The system shown in FIG. 1 includes an image display device 11, a computer central processing unit 12, a keyboard 13 having cursor keys, a mouse 14, and the like. ing.

The central processing unit 12 of the computer displays an image on the image display device 11. FIG. 2 (a),
(B), (c) shows an example of the displayed image. In the example of the image shown in FIG. 2A, for example, there is a partial shape 21 representing an object or the like to be edited in the image, and the outline of the partial shape is represented by a coordinate data sequence 22.

Conventionally, in order to change and edit the shape of the partial shape 21, the outline coordinate data sequence 22 of the partial shape is obtained by operating procedures shown in FIGS. 2 (a), 2 (b) and 2 (c). The coordinates were changed and modified. That is, as a first operation step, as shown in FIG. 2A, input means such as a mouse 14 and a keyboard 13 having cursor keys are used.
The position of the arrow-shaped cursor displayed on the image display device 11 is moved, the cursor is made to coincide with, for example, a single coordinate 23 in the outline coordinate data sequence 22 of the partial shape, and a drag operation is performed. The coordinate data value of one coordinate 23 is changed and edited.

Next, as shown in FIG. 2B, as a second operation step, a contour coordinate data series 2
In the same manner as described above, a cursor operation is performed on, for example, the single coordinate 24 of the two, and a drag operation is performed to change and edit the coordinate data value of the single coordinate 24.

After the completion of the second operation step, as shown in FIG. 2C, a third operation step is performed on the single coordinate 25 of the outline coordinate data series 22 of the partial shape. In the same manner as described above, the drag operation is performed after the cursor is matched, and the coordinate data value of the single coordinate 25 is changed and edited. Hereinafter, through the same operation steps, the single coordinate data value of the outline coordinate data series 22 of the partial shape is changed and edited to change and edit the outline of the partial shape.

FIGS. 3 (a), 3 (b) and 3 (c) show an operation method for change editing based on an embodiment of the present invention. In the example of the image shown in FIG. 3A, for example, there is a partial shape 31 representing an object or the like to be edited in the image, and the outline of the partial shape is represented by a coordinate data sequence 32. Further, the image display device 11 includes:
For example, a circular cursor 33 for displaying an editable area is displayed, and the position of the circular cursor is set to, for example, ((FIG. 3) by input means such as a mouse 14 and a keyboard 13 having cursor keys. It can move in the direction of the arrow shown in a).

As a result of moving the position of the circular cursor, if a part of the coordinate data series 32 is included in the editable area represented by the circular cursor 33 as shown in FIG. The plurality of coordinate data values of the data series 32 are changed to the same values as the coordinates on the outline of the editable area displayed in the shape of the cursor.

When the position of the circular cursor is further moved,
As shown in FIG. 3C, a plurality of coordinate data values of the coordinate data series 32 are changed to the same values as the coordinates on the outline of the editable area displayed in the shape of the cursor, as described above.

That is, the operation of changing and editing the value of the coordinate data series once determined is performed by inputting means such as a mouse 14 and a keyboard 13 having a cursor key. Just move.

Next, a case where a plurality of coordinate data values are changed and edited will be described with reference to FIG. When a part of the coordinate data series 41 is included in the editable area represented by the circular cursor, intersections 42 and 43 between the coordinate data series 41 and the editable area represented by the circular cursor exist. However, the contour of the editable area has a contour 45 on one side of the editable area and a contour 45 on the opposite side, with the intersections 42 and 43 as the centers.

The plurality of coordinate data values are changed to the same values as the coordinates on the outline of the editable area displayed in the shape of a cursor, but as shown in FIG. 4A, one of the editable areas is changed. Whether the coordinates are changed to the same value as the coordinates on the outline 44 on the side or the same as the coordinates on the outline 45 on the opposite side is determined by, for example, a shift key of a predefined key on the keyboard 13. It can be determined depending on whether or not the button is pressed.

As shown in FIG. 4B, the size of the editable area is determined by using a predefined key of the keyboard 13, such as a plus (+) key or a minus (-) key. The width of the editable area can be adjusted by changing the diameter of the circle as the editable area and continuously changing it as shown by circles 46, 47, and 48.

As shown in FIG. 4C, the shape of the editable area is a square 49, a rectangle,
Alternatively, a shape such as an ellipse can be adopted.

FIG. 5 shows an example of the processing performed by the central processing unit 12 of the computer according to the embodiment of the present invention. In the routine of FIG. 5, the processing may be started each time the operator moves the mouse 14 and the interrupt processing is instructed to the central processing unit 12, or the processing may be started every elapse of a predetermined time. .

When the process starts, it is determined in step 501 whether or not the process is to be terminated. If not, the process proceeds to step 502.

In step 502, it is determined whether or not the plus (+) key of the keyboard 13 has been pressed. If the key has been pressed, the flow advances to step 503 to increase the diameter of the editable area. If the plus (+) key of the keyboard 13 has not been pressed, the process proceeds to step 504.

In step 504, it is determined whether or not the minus (-) key of the keyboard 13 has been pressed. If the key has been pressed, the flow advances to step 505 to decrease the diameter of the editable area. If the minus (-) key of the keyboard 13 has not been pressed, the process proceeds to step 506.

In step 506, it is determined whether or not a coordinate series is included in the editable area. If no coordinate series is included in the editable area, the process returns to step 501 without doing anything. If the editable area includes a coordinate series, the process proceeds to step 507.

In step 507, it is determined whether or not the shift key of the keyboard 13 has been pressed. If not, the process proceeds to step 508, and if it has been pressed, the process proceeds to step 509.

In step 508, the coordinate data value to be edited is changed so as to be on the contour coordinates of the editable area in the clockwise direction from the upper intersection to the lower intersection with the editable area. Return to.

In step 509, the coordinate data value of the edit target is changed so as to be on the contour coordinates of the editable area in the counterclockwise direction from the upper intersection to the lower intersection with the editable area. Return to processing.

In the embodiment of the present invention, the coordinate data values to be edited are matched so as to be on any one of the outline coordinates of the editable area. If is a finite subregion in,
A similar effect may be obtained by using a means for calculating the logical sum of the finite area to be edited and the editable area, a means for masking the finite area to be edited with the editable area, or the like.

[0030]

According to the present invention, when it is necessary to change and edit a coordinate series representing a partial area or a boundary of an image,
It is possible to change and edit multiple coordinate data values at the same time simply by moving the position of the cursor, without performing the complicated operation of dragging each single coordinate with the mouse as in the conventional case. Therefore, there is an effect that a coordinate series representing a partial area or a boundary of an image can be easily changed and edited.
