Field of the Invention The present invention relates to a sewing data creating device and a sewing data creating program, and more specifically, a sewing data creating device for creating coordinate data corresponding to a needle drop point on a screen and creating sewing data. And a sewing data creation program.

[0002]

2. Description of the Related Art Conventionally, when creating sewing data for a sewing machine, a digitizer is connected and a coordinate point sequence is created by digitizing from an original picture to create sewing data, or coordinate values are specified directly from the keyboard. Or, a predetermined shape is drawn by designating a position on the screen with a mouse or the like, and the coordinate value of the stitch is created from the designated position to create the sewing data.

[0003]

However, in the conventional sewing data creating apparatus, it is necessary to use an expensive digitizer or the like to determine the coordinate position, and the keyboard or mouse can be used without using the digitizer. If the coordinate values are directly specified, there is a drawback that complicated processing is required.

On the other hand, inexpensive scanners have become available in recent years, and sewing data can be created with a cheaper structure by assisting position input by using an image image read by the scanner. However, when the image data is read to create the sewing data, it is difficult to accurately read the image data in accordance with the sewing data.

An object of the present invention has been made in view of the above problems, and it is an object of the present invention to make it possible to easily create reliable sewing data from an image.

It is another object of the present invention to easily grasp the order of needle drop positions of sewing data and to easily edit and create sewing data.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in detail below based on the embodiments shown in the drawings.

FIG. 1 shows a schematic configuration of a sewing data creating apparatus of the present invention. The sewing data creating apparatus is a personal computer 1, an input device such as a keyboard 2 and a mouse 3 connected to the personal computer 1, and an image input. It includes a scanner 4 for display, a color monitor 6 for display, and the like. The sewing data created in accordance with the sewing data creation program can be stored in an external storage device such as the FD 5 or can be directly transmitted to the sewing machine 7 via the communication means.

FIG. 2 is a block diagram showing the structure of the sewing data creating apparatus. The personal computer 1 includes a CPU 10, a ROM 15, a RAM 16, a non-volatile memory 17, a communication means 13 and a hard disk (HD).
14 etc. are built in. The CPU 10 is responsible for overall control and controls the procedure for creating sewing data in accordance with the sewing data creation program. ROM
A control program for this is stored in 15. The RAM 16 stores calculation data and is used as a work area, and the non-volatile memory 17 stores a sewing data creation program, other data necessary for creating sewing data, setting data and the like. The communication means 13 is, for example, a serial communication port, and can send the created sewing data to the sewing machine 7.

An input device 11 such as a keyboard 2 and a mouse 3 is connected to the CPU 10, and operations such as creation, editing and saving of sewing data can be performed with these input devices. In, an image read by the scanner 4 is input, and the image is stored in the HD 14. The process of creating and editing these input data, images, and other sewing data can be displayed on the monitor 6.

Next, the flow of creating sewing data with such a configuration will be described with reference to the drawings starting from FIG.

First, in creating sewing data, various images such as a pattern to be used as an original picture (draft) are read by using the scanner 4, and a file name is designated for each image and saved in the HD 14. In this way, of the image files read by the scanner, a desired image file is designated and read on the image file read designation screen as shown in FIG. 4A, and the background (original picture) of sewing data creation Is displayed on the monitor 6 (step S1).

At this time, since the read image image does not necessarily match the scale of the display screen of the monitor 6, the image image is adjusted to the scale of the display screen by the subroutine shown in FIG. for that reason,
Information on the number of dots per unit length (display density) A in the current edit screen display of the monitor is acquired (step S2).
0), and then, the dot number information (reading density) B per unit length of the image image is acquired (step S21).
The dot number information B is used because the information indicating the image reading density in dots per inch is written in the image file. On the other hand, if there is no image read density information, the image density can be specified by specifying the number of dots per inch or the actual length of the image using the keyboard on the image density specification screen shown in FIG. Is specified.

Subsequently, the image image is enlarged or reduced at an A / B ratio (step S22), and the enlarged or reduced image image is displayed on the monitor screen (step S2).
3). As shown in FIG. 6A, this display is displayed so that the center position 20a of the image image 20 coincides with the origin O of the editing coordinate system. This is step S2 in FIG.
Equivalent to.

However, the position of the image image and the position for designating the needle drop point at the time of creating sewing data are generally different from each other, and it is difficult to specify the needle drop point along the image image as it is. The image images are aligned (step S3 in FIG. 3). The details are shown in FIG. First, the center coordinate P of the input coordinate system is acquired (step S30). This is done by designating the X and Y values in the center position coordinate designation dialog, as shown in FIG. Then, drawing is performed from the drawing start position obtained from the center coordinates of the image image and the vertical and horizontal sizes thereof (step S31).

Alternatively, this alignment is shown in FIG.
As shown in, the position P to be matched with the image image and the sewing position on the screen is designated by the mouse, the difference in the number of dots in the drawing of both is calculated, and the image drawing is shifted by that amount and drawn. That is, in FIG. 7B, with the origin O as the first point, the coordinate value of the position is obtained with the mouse (step S32), and subsequently, the point P is obtained as the second point (step S33). ), The difference between the coordinate values is calculated (step S34). Then, the difference is added to the center coordinates of the image image (step S35), and drawing is performed from the drawing start position obtained from the drawing center point P and its vertical and horizontal sizes (step S36).

Further, this movement amount may be directly specified by a keyboard as shown in FIG. 8B instead of being specified by the mouse. At this time, as shown in FIG. 8C, the rotation angle θ of the image image is also designated, and the image image is rotated to perform drawing. FIG. 6B shows the image image 20 in which the center position is moved and the angle is rotated for alignment as described above.

In this way, the original image is set at a predetermined position and angle, and then the shape of the needle drop point is created in accordance with the image as shown in the data creation screen shown in FIG. 9 (A). I will do it. For this, the shape is designated by moving the cursor position to a representative point such as the contour points P1 to P10 of the image image 20 with the mouse and plotting (clicking) it. The sewing data creation program automatically calculates the coordinate values of the points connecting the points P1 to P10 at the specified pitch and displays them as black points, and the coordinate values of these black points are the needle drop points. Then, the movement amount between the needle drop points is output to a predetermined format, and sewing data is created as vector data. The above corresponds to step S4 in FIG.

When the image image 20 and the sewing shape data are simultaneously drawn on the sewing data creation screen of FIG. 9A, the image image 20 obstructs the detailed shape of the sewing shape. Since there is, Figure 9 (B)
On the image image ON / OFF designating screen as shown in FIG. 3, the button 22 of “close bitmap” is clicked. As a result, the image image 20 can be hidden, and the image image 20 can be displayed by clicking the “display bitmap” button 21.

Further, when the image image is a black and white image, it does not pose a problem, but in the case of a color image image, since coordinates and other information are displayed in color on the sewing screen, the sewing data is created or edited. It becomes the same color and cannot be distinguished. In that case, if you specify "Yes" for "Automatic color change of bitmap" on the image file reading specification screen shown in FIG. 4A, a dot of the same color as the predetermined color is searched and that color is searched. Each RGB value is changed to a value obtained by subtracting a predetermined number, and an image image is taken in and drawn.

Such processing is illustrated in FIG. First, the extraction dot position of the image image is initialized (step S40), the color information of the designated dot is extracted (step S41), and it is determined whether the color information matches the color to be color-changed (step S42). If they match, a value obtained by subtracting a predetermined value from each RGB value of the designated dot is set as a new RGB value of the dot (step S4).
3). Subsequently, the dot position is updated (step S4
4), this is repeated until it is completed for all the dots (step S45).

The display position of the image can be changed by operating the vertical and horizontal scroll bars 23 and 24. When the up and down buttons 23a and 23b of the vertical scroll bar 23 are clicked, the coordinate position drawn on the editing screen moves up and down by a predetermined amount. As the coordinate position on the edit screen changes vertically, the drawing position of the image image also changes vertically. Similarly, when the left and right buttons of the horizontal scroll bar 24 are clicked, the coordinate position drawn on the edit screen is moved in the left and right direction by a predetermined amount, and the drawing position of the image image is also changed left and right accordingly.

The sewing data created in this way is
It can be stored in a recording medium such as the HD 14 or the FD 5 together with the processed image data such as movement, rotation and color change (step S5 in FIG. 3). The detailed flow is shown in FIG. First, the file name of the created sewing data is acquired (step S50), the file name of the image image is made the same as the sewing data (step S51), and the file name of the image image is written in the sewing data (step S51). S52). Then, the sewing data and the image image are stored in association with each other (step S53).

The sewing data created and saved in this way can be edited. When editing (YES in step S6 of FIG. 3), the saved sewing data is associated and saved. It is read out and edited together with the image image being displayed (step S7).

The stored sewing data and the flow of reading the image image are shown in the lower part of FIG. 11. First, the file name of the sewing data is acquired (step S54), and the sewing data is read ( Step S5
5). At this time, the file name of the image image written in the sewing data is acquired (step S56),
Read image file (step S5)
7).

As described above, when the created sewing data is edited, the image image thus saved is automatically read and the sewing data is drawn by superimposing it on the image image. Further, only the image image can be saved independently, and the association with the bitmap can be deleted.

The created sewing data is edited by a function of editing the input shape element unit and the calculated needle drop unit. By clicking with the mouse, which element is used and which needle drop is used. You can specify it. Further, the designated element / needle drop point is stored as a focused element and a focused needle drop point, and the position can be moved back and forth by one by clicking the pointer button or pressing the left and right arrow keys. Here, the order before and after the element is determined by the input order, and before and after the needle drop is arranged in the order of the direction of the input shape, so the order of the needle drop points is determined.

At this time, the display color of the element is displayed in yellow for the previous element, in red for the element of interest, and in green for the next element. As a result, when the target element is moved with the pointer, the display color changes, and it is possible to intuitively understand in what order the elements are connected. Further, when the needle drop points are edited, the three needle drops before the focused needle drop point are displayed in yellow, the focused point is displayed in red, and the three trailing points are displayed in green. This screen display is shown in FIG. 12, and its flow is shown in FIG.

First, all needle drop points of the created or read sewing data are graphically displayed for each stitch, and a line segment connecting them is drawn (step S60).
Subsequently, the designated needle drop point of interest is searched, the drawing position is obtained (step S61), and the color of the needle drop point corresponding to the obtained drawing position is drawn in red (step S62).
This is indicated by reference numeral 30 in FIG. Further, three points before the needle drop point 30 of interest are searched, the drawing position thereof is obtained (step S63), and the color of the needle drop point 31 is drawn in yellow (step S64). Then, the three points after the needle drop point of interest are searched for and the drawing position thereof is obtained (step S6).
5) Then, the color of the needle drop point 32 is drawn in green (step S66).

In this manner, each time the needle drop point of interest is designated, the display form (color) of the needle drop point of interest and the needle drop points before and after it change, and the order of the needle drop points is intuitively identified. Since it becomes possible to edit and create sewing data easily. The sewing data created by editing can be similarly stored in the recording medium.

In the above embodiment, the sewing data creation is
Although it is configured by a personal computer, it may be realized by providing the configuration shown in FIG. 2 on the sewing machine.

[0038]

As described above, according to the present invention,
Since the coordinate position for needle drop can be designated along the image image adapted to the sewing data creation screen, accurate sewing data can be created by a simple operation.

Further, in the present invention, since the created sewing data is stored and read in association with the image image as a basis thereof, the sewing data can be easily edited.

Further, in the present invention, the needle drop point of interest and the needle drop points before and after it are displayed by changing the display form, so that it is possible to clearly grasp the sewing direction or the order, and the reliability is improved. It is possible to create sewing data with
