A method and the device for acquiring and processing measurement quantities in a sewing machine (1) using at least one camera (25), situated on a sewing machine (1), for the acquisition and processing of image data for sewing machine elements and sewing elements. An image processing unit connected downstream from the camera (25) processes the images supplied by the camera (25), taking into account data stored in a target quantity memory, and influences the behavior of the machine control unit dependent on the result of the processing.

A method and apparatus for stitching a workpiece, such as a quilt, is disclosed. The method comprises displaying a predetermined pattern on a display and manipulating the predetermined pattern on the display. The display includes an indicator corresponding to a position of a sewing head relative to the workpiece. The method further includes moving a control handle operably connected to the sewing head to move the indicator relative to the pattern on the display and move the sewing head relative to the workpiece. Devices to practice the method include sewing machines having a sewing head moveable relative to a workpiece and a control handle operably connected to the sewing head to move the sewing head relative to the workpiece, wherein the display showing a pattern to be sewn is mounted relative to the control handle for movement with the control handle.

A sewing machine includes a bed portion, a conveyance portion, a sewing portion, an image capture portion, a projector, a processor, and a memory. The conveyance portion is configured to convey a sewing object placed on the bed portion. The memory is configured to store marker information and computer-readable instructions that, when executed by the processor, instruct the processor to perform processes. The processes include causing the image capture portion to perform the image capture at a predetermined timing, during a conveyance period, identifying the marker in a captured image, using the marker information stored in the memory, identifying a projection position corresponding to the identified marker, when the marker is identified, and causing the projector to project the projection image indicating the identified projection position, while following a movement of the marker on the sewing object being conveyed.

Software converts a photographic image into realistic and customized embroidery. Software reads photographic image, down-sampling or up-sampling so that a single pixel has a Density, One Grayscale image is created to calculate derivatives for each pixel using Sobel operator to calculate angle and magnitude and stores in a Sobel table. One Color Image is created to materialize and reduce color selection. A series of polylines are calculated to connect same-color pixels using the pixel's angle from the Sobel table. Polylines are reduced to a manageable size first by multiplying all points by Density resulting in stitch data in physical units, and by using a series of rules and formulas involving angles and magnitudes of each pixel from the Sobel table, Commands are appended to an embroidery machine to generate the final embroidery.

A sewing machine includes a display which displays a pattern and a marking. A marking-data disposing position specifier specifies the disposing position of another pattern relative to the pattern. A marked pattern replicator displays, on the display, plural marked patterns that are the patterns on which the corresponding markings are disposed. The positions where the plural marked patterns are displayed are set based on the markings of the plural marked patterns. After the display positions of the plural marked patterns are set, the marking of the marked pattern is deleted. Accordingly, pattern data of a new pattern is created.
