The present invention relates to a method for manufacturing a embroidery pattern or a quilting pattern of cloth for an interior panel of a vehicle, by which the embroidery pattern or the quilting pattern is manufactured individually or simultaneously on the cloth that is the interior panel for the vehicle by using a computer-aided embroidery machine.

An embroidery sewing machine calculates the number of designs to be used for sewing for a length that is closest to a desired sewing length, based on the desired sewing length and information regarding the designs. The embroidery sewing machine calculates the sewing length based on the calculated number of designs and the information regarding the designs. Furthermore, the embroidery sewing machine adjusts the length of each design such that the calculated sewing length matches the desired sewing length, and converts the adjusted data of the designs into embroidery data. This enables sewing such that the sewing start and end points match each other or junction matching is secured, even in a case of sewing in the form of various kinds of combinations of curves and lines or the like. In addition, this provides an embroidery sewing machine that is capable of executing sewing with an improved appearance.

A sewing machine includes a sewing portion, a movement portion, a processor and a memory. The memory is configured to store computer-readable instructions that, when executed by the processor, instruct the processor to perform processes. The processes include acquiring pattern data indicating positions of a plurality of needle drop points to sew a pattern, acquiring a position of a sewing start point of the pattern, performing first correction, performing second correction that uses the acquired position of the sewing start point as a base point, and corrects the pattern data, by changing, by an acquired change amount, the positions of the plurality of needle drop points represented by the pattern data corrected by the first correction, and controlling the sewing portion and the movement portion and sewing the pattern on the sewing object, in accordance with the pattern data corrected by the second correction.

A method of generating an image that shows an embroidery area in an embroidery frame for computerized embroidery includes: acquiring a first image of a calibration board that has multiple feature points forming a contour approximating an embroidery area defined by the embroidery frame; identifying the feature points of the calibration board in the first image to acquire multiple graphical feature points; acquiring a geometric curved surface that fits the graphical feature points and that includes multiple curved surface points; acquiring a second image in which the embroidery area of the embroidery frame is shown; and performing image correction on the second image based on the geometric curved surface to generate a corrected image.

Presented are a method, apparatus, and computer-readable medium for stitching. The method includes examining, by an examiner, an embroidery design, wherein the examiner is operably coupled to a controller and a sewing head, and wherein the controller comprises a memory having a capacity, and wherein the controller is operable to cause the sewing head to stitch a work piece. The method further includes determining, by the examiner, a needle drop location of each stitch of the embroidery design, and dividing, by the examiner, the examined embroidery design into a plurality of separate sections. The method still further includes transmitting the plurality of separate sections at a plurality of different times to the controller such that the controller the plurality of separate sections do not exceed the capacity of the memory at any one of the plurality of different times.

A non-transitory computer-readable medium stores computer-readable instructions. The instructions, when executed, cause a processor of a sewing data generation device configured to generate sewing data to perform processes. The processes include acquiring pattern data to sew an embroidery pattern. The processes further include setting an outline having an offset portion and a complementary portion on the basis of the pattern data. The outline is a single line surrounding the outside of a contour of the embroidery pattern. The offset portion is a part of the single line and is offset from the contour toward the outside of the embroidery pattern by a predetermined amount. The complementary portion is another part of the single line and being offset from the contour toward the outside of the embroidery pattern by an amount larger than the predetermined amount. The processes also include generating sewing data to sew the outline.

A decoration pattern data generating apparatus includes: a controller, the controller being configured to control the decoration pattern data generating apparatus to select an embroidery pattern to be sewn, specify an outline of the embroidery pattern, based on embroidery pattern data for sewing the selected embroidery pattern; set an area outside the specified outline, as a decoration area; and generate decoration pattern data for sewing a decoration pattern in the set decoration area.
