[0010]
As described above, the embroidery sewing machine can perform embroidery sewing using the embroidery frame 20 having a size four times as large as the embroidery possible range K by sequentially rotating the embroidery frame 20 and executing embroidery sewing. The data for use in such an embroidery sewing machine can be generated by the embroidery data creation apparatus shown in FIG.
Accordingly, various modes such as data generation for two sections or multi-section edge stitch data generation according to the corresponding embroidery sewing machine are possible.
It is also possible to provide a configuration that specifies the number of divisions and a division method for dividing an image.
[0011]
The operation will be described with reference to FIG. Here, for the sake of simplicity, the case of dividing into two sections will be described.
When there is a slide input designation by the slide input designation device 3 (step S1), and the user divides the original image G into two steps and causes the image scanner 2 to read, the first step image is first captured (step S3). ), Stitch data and display data are generated based on the image data (step S4). At the same time, control data is generated (step S5). Next, the second step image is captured (step S6), and similarly, stitch data and display data are generated (step S7), and control data is generated (step S8). Then, data to be displayed by combining the first image and the second image is generated (step S9), and data for performing a slide instruction notification between the first image and the second image in the embroidery sewing machine or the like is generated. Generate (step S10), and store the generated data in the memory card 15 (step S11). If it is not a slide input in step S1, an image is simply captured (step S12), pattern stitch data and display data are generated (step S13), and further control data is generated (step S14). Is stored in the memory card 15.
With the above configuration, the original image G having a size exceeding the embroidery range K is divided and input by the image scanner 2, and stitch data, display data, control data, and the like for sewing the pattern having the size based on the original image G Slide instruction notification data can be generated.
[0012]
In the above description, the original image G is divided and input. However, the original image G having a size exceeding the embroidery range K is input by a scanner or the like, or the small original image G within the embroidery range K is input. When the image data is input by the image scanner 2 and enlarged by the pattern enlargement device 6 to obtain image data exceeding the embroidery range K, it is possible to divide the image and generate data such as stitch data.
After designating the slide by the slide input designating device 3, by designating integral reading by the step / integral designating device 4, the original image G read in one step is enlarged by the pattern enlarging device 6, and the enlarged image is divided. It is supposed to enter the mode.
