However, the stitch data used for the embroidery sewing machine having the above-mentioned structure has been conventionally supplied by an apparatus maker or the like, and a large embroidery stitch data based on the original image desired by the user is provided. It could not be created. That is, devices that read an original image with a scanner or the like and create stitch data based on the image have already been put to practical use and are commercially available, but all of them correspond to standard embroidery frames of limited size. To date, there has not been provided an apparatus that can generate only the stitch data to be created and that can create the stitch data corresponding to the large embroidery frame as described above. An object of the present invention is to solve the above-mentioned problems of the prior art.

[0004]

In order to achieve the above object, an embroidery data creating apparatus according to the present invention comprises: means for providing data of an image to be embroidered; and means for dividing the image into two or more images. Means for generating stitch data based on the divided image; and changing a relative position of the embroidery frame and the embroidery object between the sewing of the one divided image and the sewing of another image. And means for generating notification data so as to make a notification about.
According to the above configuration, even if the image exceeds the size that can be embroidered, the stitch data can be generated by dividing the image into two or more. Since notification data for notification of a change in the relative position between the embroidery frame and the embroidery target cloth or the like is generated, it is possible to perform display such as a change in the mounting position of the embroidery frame based on the notification data. Become. The image may be divided and input in advance, or the original image may be divided and input in a plurality of times by a scanner or the like.
