Abstract

A non-transitory computer-readable medium stores computer-readable instructions for sewing data generation executed by a processor in a sewing data generation device. The instructions comprises acquiring image data and determining a mode to determine a tendency of a plurality of thread colors to be used. The plurality of thread colors to be used is thread colors used in sewing of an embroidery pattern that represents an image represented by the acquired image data. The instructions also comprises selecting, on the basis of a target mode that is the determined mode, a plurality of thread colors among which at least one thread color is different for each of the modes, from a plurality of thread colors stored in a storage portion, as the plurality of thread colors to be used, and generating embroidery data to form, using a sewing machine, stitches of the selected plurality of thread colors to be used.

First claim

What is claimed is:

1. A non-transitory computer-readable medium storing computer-readable instructions for sewing data generation that are executed by a processor provided in a sewing data generation device, the computer-readable instructions performing processes comprising:
acquiring image data;
determining, from a plurality of modes, a mode to determine a tendency of a plurality of thread colors to be used, the plurality of thread colors to be used being thread colors used in sewing of an embroidery pattern that represents an image represented by the acquired image data;
selecting, on the basis of a target mode that is the determined mode, a plurality of thread colors among which at least one thread color is different for each of the modes, from a plurality of stored thread colors that are thread colors stored in a storage portion, as the plurality of thread colors to be used; and
generating embroidery data to form, using a sewing machine, stitches of the selected plurality of thread colors to be used.

2. The non-transitory computer-readable medium according to claim 1 , wherein
the plurality of stored thread colors are associated with each of a plurality of thread color groups each including a plurality of thread colors,
the instructions perform a process further comprising:
determining one of the plurality of thread color groups, and

the selecting of the plurality of thread colors to be used includes selecting the plurality of thread colors to be used from the plurality of stored thread colors associated with the determined thread color group.

3. The non-transitory computer-readable medium according to claim 1 , wherein
priority information for each of the plurality of stored thread colors is associated with each of the plurality of modes, the priority information indicating a priority of the selected plurality of thread colors to be used,
the priority information associated with each of the plurality of modes indicates a ranking of the priority that is mutually different for at least one of the stored thread colors, and
the selecting of the plurality of thread colors to be used includes selecting the plurality of thread colors to be used from the plurality of stored thread colors, in accordance with the priority indicated by the priority information associated with the target mode.

4. The non-transitory computer-readable medium according to claim 3 , wherein
the priority information indicates the priority on the basis of at least one of a brightness, a saturation, and a hue of the thread color.

5. The non-transitory computer-readable medium according to claim 3 , wherein
the plurality of modes include a mode that is associated with the priority information that indicates that the priority of a thread color having a low saturation is higher than the priority of a thread color having a high saturation, with respect to a plurality of thread colors that are chromatic colors having the same brightness as each other, among the plurality of stored thread colors.

6. The non-transitory computer-readable medium according to claim 3 , wherein
the plurality of modes include a mode that is associated with the priority information that indicates that the priority of a thread color having a high saturation is higher than the priority of a thread color having a low saturation, with respect to a plurality of thread colors that are chromatic colors having the same brightness as each other, among the plurality of stored thread colors.

7. The non-transitory computer-readable medium according to claim 3 , wherein
the plurality of modes includes one of
a mode associated with the priority information that excludes a thread color having a minimum brightness among the plurality of stored thread colors, from selection candidates in the selecting of the plurality of thread colors to be used, and
a mode associated with the priority information that indicates the thread color having the minimum brightness, among the plurality of stored thread colors, to be lowest ranking in the priority.

8. The non-transitory computer-readable medium according to claim 3 , the instructions perform a process further comprising:
setting a use number that is a number of the selected plurality of thread colors to be used,
wherein
the selecting of the plurality of thread colors to be used includes selecting, in accordance with the priority, a number of the plurality of thread colors to be used corresponding to the set use number, from among the plurality of stored thread colors.

9. The non-transitory computer-readable medium according to claim 8 , the instructions performing processes further comprising:
identifying, among the plurality of stored thread colors, a use frequency of the thread color corresponding to a color of each of pixels configuring the image represented by the acquired image data; and
determining, on the basis of the identified use frequency, whether the stored thread colors satisfy a predetermined condition,
wherein
the selecting of the plurality of thread colors to be used includes selecting, in accordance with the priority, the number of the plurality of thread colors to be used corresponding to the set use number, from among the thread colors determined to satisfy the predetermined condition, of the plurality of stored thread colors.

10. The non-transitory computer-readable medium according to claim 8 , the instructions performing a process further comprising:
receiving a specific thread color that is a thread color input by a user, of the plurality of stored thread colors,
wherein
the selecting of the plurality of thread colors to be used includes
selecting the received specific thread color as the thread color to be used, irrespective of the priority, and
selecting, in accordance with the priority, from among the thread colors excluding the specific thread color, of the plurality of stored thread colors, a number of the thread colors to be used corresponding to a difference between the use number and a number of the received specific thread colors.

11. The non-transitory computer-readable medium according to claim 1 , wherein
a type of a parameter relating to an image and a change amount of the parameter are associated with each the plurality of modes,
the instructions perform a process further comprising:
converting the acquired image data by changing the type of the parameter associated with the target mode in accordance with the change amount, and

when the image data is converted, the plurality of thread colors to be used are used to sew an embroidery pattern representing an image represented by the converted image data.

12. An embroidery data generation device comprising:
a processor; and
a memory storing computer-readable instructions that, when executed by the processor, perform processes comprising:
acquiring image data;
determining, from a plurality of modes, a mode to determine a tendency of a plurality of thread colors to be used, the plurality of thread colors to be used being thread colors used in sewing of an embroidery pattern that represents an image represented by the acquired image data;
selecting, on the basis of a target mode that is the determined mode, a plurality of thread colors among which at least one thread color is different for each of the modes, from a plurality of stored thread colors that are thread colors stored in a storage portion, as the plurality of thread colors to be used; and
generating embroidery data to form, using a sewing machine, stitches of the selected plurality of thread colors to be used.
