Information with respect to an embroidery frame and information with respect to a mark alignment region are acquired. The mark alignment region is displayed for guiding multiple marks that are provided to an embroidery frame in order to define an embroidery region in the embroidery frame. When the multiple marks thus displayed are all positioned within the mark alignment region, an image of the embroidery region is acquired. Image analysis is performed based on the information with respect to the embroidery frame thus acquired and the information with respect to the multiple corresponding marks within the acquired image. Subsequently, the embroidery region within the embroidery frame is determined based on the analysis result. This allows the embroidery region to be detected with high precision in a simple manner.

A sewing error management device includes a display 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 acquire an error image obtained by drawing an occurrence position of an error on a sewing pattern. The acquiring the error image is based on coordinates representing a formation position of a sewing stitch being sewn at a time point when the error occurs in sewing of the sewing pattern formed by a plurality of sewing stitches. The acquiring the error image is also based on an image showing a shape of the sewing pattern. And the computer-readable instructions further instruct the processor to display the acquired error image on the display portion.

An embroidery system includes a coloring device to color a thread. The embroidery system includes an embroidery device to perform embroidery of an embroidery design and underlay stitching. The embroidery device uses the thread colored by the coloring device for at least one of the embroidery of the embroidery design or the underlay stitching. The embroidery system includes circuitry to: create data of the embroidery design and the underlay stitching according to embroidery image data; create color data for coloring the thread to be used for coloring the at least one of the embroidery of the embroidery design or the underlay stitching; acquire roughness data representing roughness impression of the embroidery image data; and change an embroidery density of the embroidery design according to the roughness data.

Tools are provided that communicate to a pattern designer how much yarn is being used on every needle for a given tuft height pattern and permit the designer to adjust the pattern accordingly to balance the yarn usage on the needles. An electronic representation of a pattern design is received for controlling a carpet tufting operation. The pattern design includes a pile height per tuft. A grid is provided for representing the pattern design using different visual cues to represent different pile heights. A graph depicting use-of-yarn per needle for the carpet tufting operation is generated. The grid and the graph can be on a common user interface and can be viewable at the same time on a display device.

In one preferred mode, the operator selects by the touch panel 2 a pattern from the displayed patterns on the display 1 and starts the embroidery by operation of the start/stop switch. The CPU 10 is checking the detection signal from the sensor 3 and when the signal is on, the CPU 10 keeps the display 1 in operation. When the operator goes out from the sensor detectable area 60, the signal of the sensor 3 disappears and the CPU 10 generates the LED display 4 indicating the progress of the sewing. Since the operator can see the LED display 4 from the outside of the display visible area 61, the operator recognizes the conditions of the machine A.

An embroidery system includes a data reading device to read three-dimensional data of a design of an embroidery. The embroidery system includes processing circuitry to process the three-dimensional data read by the data reading device, to create embroidery data using height information included in the three-dimensional data. The embroidery system includes an embroidery forming section to form the embroidery on a target object according to the embroidery data created by the processing circuitry. The embroidery system includes a recording head to discharge a liquid droplet from a nozzle. The embroidery system includes control circuitry to control an operation of the recording head. The embroidery data includes data relating to an embroidery density that is a density of a thread in the embroidery and data relating to an application amount of the liquid droplet to be applied to the thread in the embroidery.
