1. An embroidery data creation apparatus comprising:

  • a thread color relation value storage device that stores a color relation value that corresponds to a color, for each embroidery thread which is used in an embroidery data, wherein the embroidery data is created based on image data already formed with an aggregate of pixels;

    a preview image creation device that creates a preview image required to confirm a result of an embroidery performed using the embroidery data created based on the image data;

    a preview display device that displays the preview image created by the preview image creation device;

    a reference region specification device that specifies as a color modification reference region at least one region in the preview image being displayed on the preview display device;

    a thread color selection device that selects a thread color to be used for the reference region specified by the reference region specification device from among the thread colors whose color relation values are stored in the thread color relation value storage device;

    an image data color modification device that modifies the color of the image data by changing the color relation value of the pixels in the image data based on the color relation value corresponding to a color of a reference image region which is a region in the image data corresponding to the reference region and the color relation values stored in the thread color relation value storage device corresponding to the thread color selected by the thread color selection device; and

    an embroidery data creation device that creates the embroidery data from color-modified image data obtained after modifying the color by using the image data color modification device,wherein the image data color modification device comprises;

    a calculation formula determination device that determines a calculation formula that is used when changing the color relation values of the pixels in the image data, based on the color relation value of the reference image region and the color relation value of the selected thread color; and

    a post-modification color relation value calculation device that substitutes the color relation value of a modification pixel in the image data whose color relation values are to be changed into the calculation formula determined by the calculation formula determination device, thereby calculating a post-modification color relation value of the modification pixel.
