Abstract

When marks all align with a mark alignment region in an image, an image is acquired for an embroidery frame and embroidery design sewn to a portion of a cloth mounted on the frame. Image analysis is performed based on correspondence between acquired information for the embroidery frame and for the marks. The embroidery region of the embroidery frame is determined based on analysis results. Acquired images of the cloth having the embroidery design portion and an embroidery design to be sewn to it are displayed. The embroidery design image to be sewn is edited to connect it to the image of the embroidery design already sewn to the portion in the displayed image. This prevents the occurrence of overlapping or gaps between embroidery design units even if accumulated shrinkage occurs in sewing, or slight alignment errors occur in position or rotation when cloth is mounted on the embroidery frame.

First claim

What is claimed is:

1. An embroidery design connecting data generating apparatus comprising:
an embroidery frame information acquisition unit that acquires information with respect to an embroidery frame and information with respect to a mark alignment region displayed on a display unit for guiding a plurality of marks arranged at preset positions within the embroidery frame for defining an embroidery region of the embroidery frame;
an image acquisition unit that acquires an image of the embroidery frame and an embroidery design sewn to a portion of a cloth mounted on the embroidery frame when the plurality of marks are all aligned with the mark alignment region in an image displayed on the display unit;
an acquired image analyzing unit that performs image analysis for the plurality of marks in the image acquired by the image acquisition unit based on a correspondence with the information with respect to the embroidery frame acquired by the embroidery frame information acquisition unit;
an embroidery region determination unit that determines the embroidery region of the embroidery frame based on an analysis result obtained by the acquired image analyzing unit; and
an embroidery design image editing unit that edits an image of an embroidery design to be sewn to the cloth such that it is connected to the image of the embroidery design that has already been sewn to the portion of the cloth in a state in which the display unit displays the image acquired by the image acquisition unit for the embroidery design that has already been sewn to the portion of the cloth, the image of the embroidery design to be sewn to the cloth, and an image of the embroidery region thus determined.

2. The embroidery design connecting data generating apparatus according to claim 1 , comprising an embroidery design data generating unit that generates data of the embroidery design based on the information with respect to the embroidery frame.

3. The embroidery design connecting data generating apparatus according to claim 1 , wherein the embroidery design to be sewn to the cloth is the same as the embroidery design that has been sewn to the portion of the cloth.

4. The embroidery design connecting data generating apparatus according to claim 2 , comprising an embroidery design data editing unit that edits the data of the embroidery design generated by the embroidery design data generating unit, based on the image of the embroidery design edited by the embroidery design image editing unit before it is sewn to the cloth.

5. The embroidery design connecting data generating apparatus according to claim 1 , comprising an input operating unit that allows a user to input an operating instruction,
wherein the embroidery design image editing unit edits the image of the embroidery design to be sewn to the cloth, according to an operating instruction received via the input operating unit.

6. The embroidery design connecting data generating apparatus according to claim 5 , comprising a sewing execution number-of-times determination unit that determines a number of times that sewing of the embroidery design is to be performed for the cloth, based on the information with respect to the embroidery frame acquired by the embroidery frame information acquisition unit and information received via the input operating unit with respect to a region of the cloth to be subjected to the embroidery sewing.

7. The embroidery design connecting data generating apparatus according to claim 1 , wherein the image acquisition unit performs image acquisition giving priority to a region of the cloth that is not adjacent to other regions thereof each having an embroidery design sewn portion.

8. The embroidery design connecting data generating apparatus according to claim 7 , comprising an operation guidance unit that provides a user with at least one from among a guidance display and an audio guidance in the image acquisition operation of the image acquisition unit.

9. The embroidery design connecting data generating apparatus according to claim 1 , wherein the embroidery design image editing unit modifies the image of the embroidery design by shifting at least one from among a vertex or otherwise a side of the outer shape of the embroidery design in an image having a polygonal shape.

10. The embroidery design connecting data generating apparatus according to claim 1 , comprising a gravity direction detection unit that detects a gravity direction,
wherein the display unit further displays an image acquisition orientation guidance display for guiding an alignment between an image acquisition optical axis of the image acquisition unit and the gravity direction based on a detection result obtained by the gravity direction detection unit.

11. The embroidery design connecting data generating apparatus according to claim 10 , wherein, when the marks are aligned within the mark alignment region and when judgment has been made based on the detection result obtained by the gravity direction detection unit that the image acquisition optical axis aligns with the gravity direction, the image acquisition unit automatically performs image acquisition.

12. The embroidery design connecting data generating apparatus according to claim 11 , comprising a correction unit configured such that, when there is an inclination between the display unit and the embroidery region thus determined in the image acquired by the image acquisition unit, the inclination is corrected.

13. An embroidery design connecting data generating method employed in an embroidery design connecting data generating apparatus, the embroidery design connecting data generating method comprising:
acquiring, by an embroidery frame information acquisition unit of the embroidery design connecting data generating apparatus, information with respect to an embroidery frame and information with respect to a mark alignment region displayed on a display unit for guiding a plurality of marks arranged at preset positions within the embroidery frame for defining an embroidery region of the embroidery frame;
acquiring, by an image acquisition unit of the embroidery design connecting data generating apparatus, an image of the embroidery frame and an embroidery design sewn to a portion of a cloth mounted on the embroidery frame when the plurality of marks are all aligned with the mark alignment region in an image displayed on the display unit;
performing image analysis, by an acquired image analyzing unit of the embroidery design connecting data generating apparatus, for the plurality of marks in the image acquired by the image acquisition unit based on a correspondence with the information with respect to the embroidery frame acquired by the embroidery frame information acquisition unit;
determining, by an embroidery region determination unit of the embroidery design connecting data generating apparatus, the embroidery region of the embroidery frame based on an analysis result obtained by the acquired image analyzing unit; and
editing, by an embroidery design image editing unit of the embroidery design connecting data generating apparatus, an image of an embroidery design to be sewn to the cloth such that it is connected to the image of the embroidery design that has already been sewn to the portion of the cloth in a state in which the display unit displays the image acquired by the image acquisition unit for the embroidery design that has already been sewn to the portion of the cloth, the image of the embroidery design to be sewn to the cloth, and an image of the embroidery region thus determined.

14. A sewing system comprising an embroidery design connecting data generat
