Description

Sewing data writing device and sewing data writing program {APPARATUS FOR PRODUCING SEWING DATA AND PROGRAM FOR PRODUCING SEWING DATA}

The present invention relates to a sewing data creating apparatus and a sewing data creating program for acquiring a coordinate value corresponding to a needle drop point on a screen to create sewing data.

When creating sewing data for a conventional sewing machine, use a digitizer to create a coordinate sequence by using the digitizer to create sewing data, create direct coordinate values from the keyboard, or specify a position on the screen from the mouse. By drawing a predetermined shape, a seam coordinate value was created from a designated position to create sewing data.

However, in the conventional sewing data generating apparatus, an expensive digitizer or the like needs to be used to determine the coordinate position, and complicated processing is required when specifying the coordinate value directly from the keyboard or the mouse without using the digitizer. Has the drawback.

On the other hand, recently low cost scanners have become available, so that sewing data can be created at a lower cost by assisting in position input using the image image read by the scanner. However, in the case of creating sewing data by reading an image image, it is difficult to accurately read the image image, and thus there is a problem that it is difficult to obtain accurate sewing data.

An object of the present invention is to make it possible to easily create reliable sewing data from an image image.

In addition, an object of the present invention is to be able to easily grasp the order of the needle drop position of the sewing data, it is possible to easily edit and create the sewing data.

Moreover, the subject of this invention is making it possible to produce sewing data by simple operation.

EMBODIMENT OF THE INVENTION This invention is demonstrated in detail based on the Example shown to the following figure.

In Fig. 1, the sewing data generating apparatus includes a personal computer 1, input devices such as a keyboard 2 and a mouse 3 connected to the personal computer 1, an image input scanner 4, And a color monitor 6 for display. The sewing data created in accordance with the sewing data creation program can be stored in an external storage device such as a flexible disk (FD) 5 or transmitted directly to the sewing machine 7 through communication means.

In Fig. 2, the configuration of sewing data creation is shown as a block, and the personal computer 1 includes a central processor unit (CPU) 10, a read-only memo (ROM) 15, and a random access memory (RAM) 16. ), A nonvolatile memory 17, a communication means 13, a hard disk (HD) 14, and the like. The CPU 10 is in charge of the entire control and controls the order when creating the sewing data according to the sewing data creating program. The ROM 15 stores a control program therefor. The RAM 16 stores operation data or is used as a work area. The nonvolatile memory 17 stores a sewing data creating program, data necessary for creating sewing data, setting data, and the like. The communication means 13 can, for example, transmit sewing data created through a serial communication port to the sewing machine 7.

In addition, an input device 11 such as a keyboard 2 or a mouse 3 is connected to the CPU 10, and the input device 11 can be used to create, edit and save sewing data. The image read by the scanner 4 is input to the CPU 10, and the image is stored in the HD14. 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 in such a configuration will be described with reference to the drawings below in FIG. 3.

First, various types of images, such as paper, which are to be used as the original image (bottom image) in reading sewing data, are read using the scanner 4, and file names are designated for each image image and stored in HD14. In this way, among the image files read out from the scanner, a desired image file is designated on the designated screen for reading the image file as shown in Fig. 4A, and displayed on the monitor 6 as a background (original picture) for sewing data creation. (Step S1).

At this time, the read image image does not necessarily match the scale of the monitor 6 display screen, so that " display the image image according to the screen scale " in step S2 of FIG. Specifically, the subroutine shown in FIG. 5 makes the image image fit the scale of the display screen. Therefore, the number of dots per unit length information (display density) A in the display of the editing screen of the current monitor is obtained (step S20), and then the number of dots per unit length information (read density) B of the image image is obtained. It acquires (step S21). The dot number information B is used because information indicating the read density of the image in dots per inch is written in the image file. On the other hand, when there is no read density information of the image, the image density is designated by specifying the number of dots per inch or the actual length of the image by the keyboard on the image density specifying screen shown in Fig. 4B.

Subsequently, the image image is enlarged or reduced in the ratio A / B (step S22), and the enlarged and reduced image image is displayed on the screen of the monitor (step S23). This display is displayed such that the center position 20a of the image image 20 coincides with the origin O of the edit coordinate system as shown in Fig. 6A.

However, the position of the image image and the position at which the needle drop point is designated at the time of sewing data are generally hidden so as not to overlap. In that state, it is difficult to specify the needle drop point along the image image. "Alignment of the image image" is performed.

Specifically, it is performed by the subroutine shown in FIG. 7 (A), for example. First, the center coordinate P of the input coordinate system is acquired (step S30). This designates and inputs X and Y values in the center position coordinate designation dialog (center position coordinate designation screen) as shown in Fig. 8A. Subsequently, drawing is performed from the drawing start position obtained from the center coordinates of the image image and the vertical and horizontal sizes (step S31).

Alternatively, this alignment is performed by specifying a position P to be aligned at the image image and the sewing position on the screen with a mouse as shown in Fig. 6A, calculating the difference in the number of dots between the two drawing images, and performing image drawing. It is also possible to draw so far. That is, in the subroutine shown in Fig. 7B, the coordinate value of the position is acquired with the mouse as the first point (O) as the first point (step S32), and the coordinate value is subsequently acquired as the second point P. (Step S33), the difference of the coordinate value 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 point P and the drawing start position obtained from the vertical and horizontal sizes (step S36).

In addition, the movement amount can be designated and input directly by the keyboard in the bitmap movement dialog (positioning screen during drawing) as shown in FIG. At this time, in the bitmap rotation dialog (drawing angle designation screen) as shown in Fig. 8C, the rotation angle θ of the image image is designated and input, and the image image is rotated to draw. The image image 20 in which the center position is moved to rotate the angle and the position is shown in Fig. 6B.

Thus, step S4 of 3 is performed after making the image image used as an original picture into a predetermined position and angle. That is, the shape of the needle drop point is created in accordance with the image image as in the data creation screen shown in Fig. 9A. This moves the cursor position to a representative point such as contour points P1 to P10 of the image image 20 by the mouse, and designates the shape by reading the coordinates of the cursor position by plotting (clicking) it. The sewing data creation program automatically calculates the coordinate values of the points obtained by dividing the line connecting each point P1 to P10 with the specified pitch, displays them as black points, and drops the needles by setting the coordinate values of these black points as needle drop points. The amount of movement between the points is output to a predetermined port map, and sewing data is created as vector data.

In addition, when the image image 20 and the sewing shape data are simultaneously drawn on the sewing data creation screen of FIG. 9A, the image shape 20 may be disturbed and the detailed shape of the sewing shape may not be known. On the ON / OFF designation screen of the image image as shown in Fig. 9B, the button 22 of "Close bitmap" is clicked. Thereby, the image image 20 can be made non-display, and when the clicker 21 of "bitmap display" is clicked, the image image 20 can be displayed.

In the case of a black and white image of an image image, it does not matter much, but in the case of a color image image, coordinates and the like are displayed in color on the sewing screen, and the same color is used for sewing data creation or editing. In this case, if "Automatic color conversion of bitmap" is designated as "Yes" in the image file reading designation screen shown in Fig. 4A, dots of the same color as a predetermined color are searched for each value of RGB of the color. Is converted to a value obtained by subtracting a predetermined number to extract and draw an image image.

This processing is shown in FIG. First, the extraction dot position of the image image is initialized (step S40), color information of the designated dot is taken out (step S41), and it is determined whether or not it matches the color to be changed in color (step S42). If there is a match, the value obtained by subtracting the predetermined value from the respective RGB values of the designated dots is used as the new RGB value of this dot (step S43). Subsequently, the dot position is changed (step S44), and the process is repeated until all dots are finished (step S45).

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

The sewing data thus produced can be stored in a recording medium such as HD14 or FD5 together with 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), and the file name of the image image is made the same name as the sewing data (step S51), and the file name of the image image is written in the sewing data (step S52). The sewing data is stored in association with the image image (step S53).

When the sewing data created and saved in this way is edited (YES in step S6 in FIG. 3), the stored sewing data is read and edited together with the stored image image (step S7).

The saved 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 obtained (step S54), and the sewing data is read (step S55). At this time, the file name of the image image written in the sewing data is acquired (step S56), and the file name of the image image is read (step S57).

When editing the sewing data thus created, the stored image image is read automatically, and the sewing data is drawn in superimposition with the image image. In addition, only the image image can be preserved independently, or the association with the bitmap can be deleted.

In addition, the created sewing data is edited by the input shape element unit and the calculated needle drop unit, and can be designated by clicking with a mouse on which element and which needle drop is to be used. In addition, the specified element / needle drop point is remembered as a locking element and a needle drop point, and the position can be hidden so that the position does not overlap one by one by clicking the pointer button or pushing down the left and right arrow keys. Here, the front and rear of the element is determined in the input order, and the front and rear of the needle drop are arranged in the direction of the input shape, so the order of the needle drop point is determined.

At this time, the display color of the element is indicated by yellow before the element, the red by the element, and the green by the element after the one. Accordingly, when the elements are hidden with the pointer, the display color changes so that the order in which the elements are connected is intuitively known. When the needle drop point is edited, the needle drop points of the front three points of the needle drop point are yellow, the ring point is red, and the next three points are displayed in green. This screen display is shown in FIG. 12, and the flow thereof is shown in FIG.

First, all needle drop points of the created or read sewing data are graphically displayed every needle, and line segments connecting them are drawn (step S60). Subsequently, the designated needle drop point is searched to obtain the drawing position (step S61), and the color of the needle drop point corresponding to the obtained drawing position is drawn in red (step S62). This is shown at 30 in FIG. Further, three points in front of the tree needle dropping point 30 are searched to obtain the drawing position (S63), and the color of the needle dropping point 31 is drawn in yellow (step S64). Subsequently, three points behind the tree needle drop point are searched to obtain the drawing position (step S65), and the color of the needle drop point 32 is drawn in green (step S66).

In this way, whenever the needle drop point is specified, the display form (color) of the needle drop point and the needle drop point before and after changes, and the order of the needle drop points can be identified intuitively. This is facilitated. The sewing data created by editing can likewise be stored in the recording medium.

In the above embodiment, the sewing data is created by a personal computer, but may be realized by arranging the configuration shown in FIG. 2 on the sewing machine.

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

In addition, in the present invention, the created sewing data is stored in association with the image image on which it is based, and is read in, so that the sewing data can be easily edited.

In addition, in the present invention, since the needle drop point and the needle drop point before and after the display are changed and displayed, the sewing direction or order can be grasped clearly, and reliable sewing data can be created.
