Title: Correction apparatus for sewing data and correction method

Abstract: A correction apparatus is designed to correct sewing data used on a sewing machine that forms an embroidery pattern on a cap by moving a needle bar upward and downward and a frame holding the cap in the X- and Y-axis directions. In the correction apparatus for correcting sewing data, the correction apparatus first reads sewing data as an original data, then finds the coordinates of a stitch point for each stitch from the read original data. The correction apparatus corrects the X coordinate of the stitch point based on a correction value that varies according to the Y coordinate, to create an execution data different from that in the original data. The correction value is calculated using the coordinate data of the Y-axis direction as a variable and a correction parameter that can be changed as a constant. As a result, the use of the corrected sewing data enables the sewing machine to form an embroidery pattern on the cap as the same as the original data indicates, unaffected by the shape of the cap and the different movement amounts between the crown side and the visor side of the cap.
