EMBROIDERY DATA PREPARING DEVICE OF SEWING MACHINE

摘要

PROBLEM TO BE SOLVED: To effectively remove noise of image data generated in reading in an original pattern by an image input device. SOLUTION: Image data of an original pattern read in by an image input device are stored in an image data memory part 41. A check bit indicating part 42a indicates check bits successively, and a periphery bit indicating part 42b indicates the peripheral bits. An all black/all white judging part 42e judges whether the peripheral bits read out by the image data memory part 41 are all black or white. If the peripheral bits are judged to be all one color, the check bits are changed to be of the same color. On the other hand, if the peripheral bits are not of one color, the check bits are stored in data as of the original colors.
