In this embodiment, this process is performed for data having a 252×252 dot configuration, every other dot for horizontal data, and every other line for vertical data. The dot data after processing is as shown in FIG. O Setting the needle drop point coordinates For the needle drop point coordinates of the stitch data, give the coordinates for setting the needle drop point in each line and between each line in advance as shown by black dots in the 5th section, and search the original data after division. Stitch data is generated using the coordinates of the left and right ends of the dot column in each row and the needle drop point coordinates located inside the coordinates. O For correction of input image deviation and generation of embroidery data,
The procedure for correcting an input image and generating embroidery data will be explained with reference mainly to FIG. 1 and FIGS. 8 to 15. In the following description, a case will be described in which the first reference point and the second reference point are used as reference markers, and the planar position and rotation angle of the read image data in the XY force direction are corrected. In FIG. 1, 5n (n=12.3...) indicates the steps of each process. Prior to step 51 in FIG. 1, the first original image is separated for each color to create a plurality of second original images. To explain using the example in Figure 8, "red", "green" and "
The first original picture ○PO consisting of three colors of ``black'' is divided into the 9th original for each color.
As shown in Figure 11, three second original pictures OPI~O
A first reference point P1 and a second reference point P2 as reference markers are provided at the same position in the reading frame to create three second original images. [1] Image reading In the image reading step, one of the second original images separated for each color is read by the image input means, and the image data is written into the VRAM of the embroidery data creation device 10. [2] Find the center coordinates of the first reference point. The center coordinates of the first reference point P1 are determined by the following processing procedure. Search within the rectangular area above the manually generated image data. In FIG. 14, dots of the image are searched in a predetermined order within a predetermined range, including the origin PO of the input original image data, and a dot somewhere among the spread reference points PI is found. Determine whether a dot is detected within the rectangular range. If no dots are detected, the input of the original image is incorrect, so the process returns to Sl and after re-inputting, the subsequent processing is performed, and if any dots are detected, the process proceeds to the next step. First, find the left and right end dot positions of a continuous dot column in that row (horizontal direction), search the row above it in the range between the two found dot positions, and if there is a dot, find the left end of that dot column. and the right end, and then perform the same operation on the row above it to find the row number immediately before the dot row disappears and the position of the left end of the dot row, that is, the upper end position Yal (FIG. 14). A search is made for the line below the do/do positions detected in S4, and the search is performed in the same manner as above to find the lower end position Yb1 (FIG. 14). Center coordinates of the first reference point P1 (X cl , Y cl
), find Ycl in the Y direction. Ycl is determined by the following formula. Ycl=(Yal+Yb1)/2 Search the continuous dot column in the row of Ycl, and search the left mX
Find the center coordinate Xcl in the X direction from al and the right 1Xbl. Xcl is determined by the following formula. Xcl-(Xal+Xbl)/2 [3] Find the center coordinates of the second reference point. S8-513 Similar to 52-S7, search for a second reference point P2 within a predetermined range from the origin PO of the original image data, and
Find the center coordinates (X c2. Y c2) of. In the process 59 from S8, it is determined whether a dot is detected within the rectangular range. If no dots are detected, the input of the original image is incorrect, so the process returns to Sl, and after re-inputting, the subsequent processing is performed. [4] Find the deviation in the rotational direction and in the X and Y directions. The rotational deviation eo of each dot of the original image data from the center coordinates of the reference points P1 and P2 is determined by the following equation. eo -tan-'((Xc2-Xcl)/(Yc2-
Ycl] Displacement X of each dot in the original image data in the X and Y directions when P1 is made to match the origin PO of the original image data
Find dSYd. X d = X cl d - Ycl [5] This is a correction calculation processing step in which each dot of the input image is moved to a corrected coordinate position. 515.516 In Sl, the input image memory is searched, and the coordinates after correction are calculated using the following formula, and in 516, the pixel (
Move the dot). If the position coordinates before correction are X, Y and the position coordinates after correction are X new, Y new, then new -X-Xc + Y-Yc -5in 19

6. Reference marker erasing step for erasing dot data at the first and second reference points After moving all the dots, the dot data at the first reference point PL and the second reference point P2 are erased. [7] Generation of embroidery data This is a stitch data generation processing step, in which stitch data is generated according to the method shown in the stitch data generation process of the flowchart shown in FIG. 2, and a color change code is added after the generation. In this embodiment, first, stitch data is generated from corrected original image data for the "red" original image pattern shown in FIG. 9, and then a color change code is added. It is determined whether there is a next color, and if there is a next color to be input, the process returns to Sl and executes the subsequent processing. In this embodiment, the above operations [1] to [7] are also performed for the "green" and "black" images in FIGS. 1O and 11. If the next color is exhausted, the process advances to S20. Add an end code and terminate the program. ○Stitch data generation process Next, details of the stitch data generation process of step 518 in FIG. 1 will be explained with reference to FIG. In the figure, Tn (n=1, 2.3, . . . ) indicates each processing step. The upper left corner of the image (21 points in the example of FIG. 13) is the starting point of the search. [11] First detection step This is a step in which the inside of a rectangle is searched and the presence or absence of image data (hereinafter referred to as a dot) can be determined. Search within a relatively narrow predetermined rectangular area in a predetermined order. In the first search, a range from the upper left end of the image to the lower right quarter of a predetermined rectangular range is searched. The presence or absence of a dot is determined, and if there is a dot, the process proceeds to T8, and if there is no dot, the process proceeds to T4. [12] Second detection step Search the line from the previous final stitching position from left to right, and when the right end is reached, search the line below from left to right. Repeat this operation until a dot is found. Starting from the previous final stitching position, search from right to left within that line, and when the left end is reached, search the line above it from right to left. Repeat step 2 until you find the dot. The presence or absence of a dot is determined, and if there is a dot, the process proceeds to T7; if there is no dot, the process proceeds to T25. If a dot is found in the searches at T4 and T5, the one with the shorter distance from the previous final stitch position is selected. If only one dot is found, select it. If the dot is not found by searching T4 and T5, please use l!
! Since the processing of the read image from the original picture No. 2 has been completed and the conversion to stitch data has been completed, a color change code is added and the process returns to the main routine shown in FIG. [13] First starting point determination step This is a step of searching the upper and lower ends of the image block and generating jump stitches. In the row with the dots selected with T2 or T7, the leftmost and rightmost dots of the dot column! Find the row above it within the range of both found dot positions, and if there is a dot, find the left and right ends of that dot column, search the row above it in the same way, and find the dot. Find the row number and left end position of the dot column immediately before the column disappears as the top end position. In the row with the dot selected in T2 or T7, find the left and right end dot positions of the dot column, search the row below it within the range of both found dot positions, and if there is a dot, search the left end of that dot column. The right end is found, and the rows below that are searched in the same way, and the row number and the left end position of the dot row immediately before the end of the dot row are found as the lower end position. IO Set the current stitch start position to be the one closest to the previous final stitch position between the top and bottom ends. ll Generate jump data between the previous final stitch position and the current stitch start position. The embroidery direction is determined depending on whether the current stitch start position is the top or bottom of the block, so the process branches to the corresponding step. The processing from 713 to T18 is a needle drop point setting step in which a straight stitch is formed from the stitch start position, a stitch is generated while searching downward from the upper end of the block, and the processed dot row is erased. , 719~T2
Processing No. 3 is a second starting point determining step in which the previous (upper) row is searched in parallel. The processes from T33 to T38 form a straight stitch from the stitch start position, generate stitches while searching upward from the bottom edge of the block, and erase the processed dot rows. Processing is a process of searching the previous (lower) row in parallel. The series of processing from 733 to T43 is basically the same as the processing from 713 to T23, except that the vertical direction is reversed, so the processing from T13 to T23 will be mainly described here. [14] Needle drop point setting step T13, T14 At T13, find the left and right ends of the dot row in the row of the stitch start position, and in the meantime set the straight stitch needle drop point, set the first needle to the left end. As shown in Fig. 5, the second needle and subsequent needles are set at positions that are related to the predetermined sewing pitch and line number, and finally, the needle drop point is set at the right end position. At T14, the dot row for the row for which the needle drop point setting has been processed is deleted from the image memory. T15~718 Find the left end of the dot column in the lower row as the next row, and if there is a dot column in the lower row, find the position related by row number between it and the right end of the previous row. Set the needle drop point from the right edge to the left edge. [15] Second starting point determination step (not shown) searches the upper row as the previous row, T19
If there is an unprocessed dot column in the previous row, T
The process proceeds to T20, and if there is no dot row, the process proceeds to T23 and thereafter. Search in the upward direction to find the top position as the starting point. Determine whether there is a starting point. The presence or absence of a start point is determined based on whether the distance from the previous final stitch position is within a certain distance. If there is a starting point, T2
If there is no starting point, proceed to T23 or later. If there is a starting point, generate a jump stitch. Although not shown, the lower row is searched to determine if there is a dot column. If there is a dot row, return to T13 and 713 to T
The process of 23 is repeated, and if there is no dot row, the process returns to T2 and the process from T2 is performed. The processing from 733 to T43 is basically the same as the processing from T13 to T23, except that the vertical direction is reversed.
The explanation will be omitted here. According to the embroidery data creation method described above, embroidery data that can be used for color embroidery is created from a plurality of second original images that are created separately for each color from the first original image.
From the first original picture ○PO shown in Fig. 8, a plurality of second original pictures 0PI-〇P3 shown in Figs. 9 to 11 are created for each color, and embroidery data is created using the embroidery data creation method explained above. However, by performing embroidery stitching, beautiful embroidery using colors is possible without overlapping each color. O Embroidery stitching with a three-dimensional effect Depending on the pattern, design, etc. of the original pattern to be embroidered, it is more effective to embroider by partially overlapping the embroidery parts of each color to create a three-dimensional effect. There is. In that case, the reference markers of the second original image should be shifted relative to each other depending on the edge, the width of each line should be made thicker, etc., and then the embroidery data should be created using the embroidery data creation method described above. By creating and sewing embroidery, some of the stitches of different colors overlap, making it possible to create beautiful colored embroidery with stitches that have a three-dimensional feel. O When setting a reference line as a reference mark The above explanation is based on the 12 images created separately for each color from the first original drawing.
Although we have explained the case where the Ml reference point and the second reference point are provided as reference marks on the W image of It is possible to perform the same processing as when a reference point and a second reference point are provided. This will be explained below with reference to FIG. The figure is $2
This is part of the W image data read from the original image, and Q is the read dot data of the reference line. The first reference point R1 and the second reference point R2 are set using an appropriate method with respect to the dot data Q of the reference line (hereinafter referred to as reference line Q).
By determining the corrected movement amount and corrected rotation angle of the original image data in the XY length direction, it is possible to obtain the corrected movement amount and corrected rotation angle of the original image data in the same manner as described above, and similarly to the above, the coordinates of the first reference point R1 are
It is used to determine the corrected movement amount in the length direction, and the corrected rotation angle can be determined from the positional relationship of the coordinates of the first reference point R1 and the second reference point R2. In the example of FIG. 16, the first reference point R1 and the second reference point R2 with respect to the reference line Q are the upper left end and lower left end points of the reference 41tQ, respectively. Instead of point R2, the point R2' at the left end of the reference line Q, which is a certain distance from the first reference point, can also be used. Further, the first reference point R1 and the second reference point R2 with respect to the reference line Q can be set in relation to the center line of the reference line Q, for example, instead of the example shown in FIG. Q When using only one reference point as a reference mark When using only one reference point as a reference mark, the first
This will be explained with reference to FIG. In the figure, a scanner guide 5 as a guide means
0, a first guide 52 and a second guide 53 are arranged on a substrate 51, and the first guide 52 extends over the upper end of the maximum movable range in the Y direction of the image scanner 20 (FIG. 3). The second guide 53 is the image scanner 20
guide in the X direction. When reading the original image data from the second original image OP4, first, the second original image OP4 is placed and fixed on the substrate 51 so that its Y-direction component is parallel to the second guide 53, and then the image scanner 20 is placed on the second original image OF2 so that its upper end is in contact with the first guide 52, and then the image scanner 20 is placed on the second guide 53.
The original image data is read from the second original image OP4 by moving it in contact with the guide surface 53a of the second original image OP4. In this case, correction of the original image data after reading is not necessary for the rotation angle, and only correction in the XY length direction is required.
It is only necessary to provide a reference mark for the second original image that serves as a reference for the position in the x and Y force directions. For example, as shown in FIG. 17, a single reference point R' can be used as the reference mark. O Embroidery data usage mode The above embodiment is an embroidery data creation device l. By setting the RAM card 30 storing the embroidery data created in the sewing machine into the sewing machine and pressing the start/stop key 41 of the sewing machine, embroidery is sewn based on the embroidery data read from the offline RAM card 30. In addition, the color change code automatically stops the sewing machine and allows you to change the upper thread color, but this can also be done online. That is, in the embodiment described above, an image processing program is stored in the ROM built into the sewing machine, a dedicated terminal is provided for the sewing machine I, an image scanner as an image scanning device is connected, and the same process as described above is performed. The original image data is read from the original image pattern, the embroidery data is created online using a processing program similar to that of the embroidery data creation device described above, the created embroidery data is temporarily stored, and embroidery is performed via a data buffer, etc. It can also be done.

【Effect of the invention】

As described above, according to the present invention, embroidery data that can be embroidered in color can be created by simple input operations using a relatively inexpensive monochrome image input device, and when input by reading the original pattern, the 2
By overlapping the desired constituent parts of the original drawings, the thickness of the overlapping part is created in some of the seams, and remarkable effects such as beautiful and three-dimensional embroidery can be achieved.
