     An image sensor  35  is provided in the interior of the head  14 . The image sensor  35  is a known complementary metal oxide semiconductor (CMOS) image sensor, for example. The image sensor  35  is disposed such that it can capture an image of an area that includes the area below the needle bar  6 , and it is capable of creating image data. The image data that the image sensor  35  outputs are stored in a specified storage area of a RAM  63  (refer to  FIG. 16 ). The relationship between a coordinate system for the image that is described by the image data that the image sensor  35  has created and a coordinate system for the whole of space (hereinafter called the world coordinate system) is established in advance by parameters that are stored in a flash memory  64 . The relationship between the world coordinate system and the embroidery coordinate system is established in advance by parameters that are stored in the flash memory  64  (refer to  FIG. 16 ). Accordingly, the sewing machine  1  is capable of performing processing that specifies coordinates in the embroidery coordinate system based on the image data. 
     The image sensor  35  in the present embodiment has a function that creates the image data with the white balance corrected. More specifically, the image sensor  35  has an auto white balance function (hereinafter called the AWB) and a manual white balance function (hereinafter called the MWB). The AWB is a function that performs color temperature correction on the image data using determined white balance values (hereinafter called determined WB values) that are determined based on color information in the image data. The MWB is a function that performs color temperature correction on the image data using set white balance values (hereinafter called set WB values). The set WB values are white balance values (hereinafter called WB values) that are set by the CPU  61 , which will be described later. The color information is information that describes color. In the present embodiment, the color information is expressed in the form of gradation values (numerical values from 0 to 255) for the three primary colors red (R), green (G), and blue (B). 
     The plurality of types of the embroidery frames and holder members that can be mounted on the moving mechanism  40  will be explained. The embroidery frame includes a first frame member and a second frame member, and it can hold the sewing workpiece using the first frame member and the second frame member. Each one of the first frame member and the second frame member is a frame-shaped member.

The holder member includes a planar portion that has a surface that is planar, and the holder member is capable of holding an object that has been placed on the planar portion. The object may be, for example, an object of image capture by the image sensor  35 . 
     An embroidery frame  50  that can be mounted on the moving mechanism  40  and a holder plate  90  that can be mounted on the embroidery frame  50  will be explained with reference to  FIG. 1  and  FIGS. 4 to 8 . The left-right direction, the top side, and the bottom side in  FIGS. 4 and 7  respectively define the left-right direction, the rear side, and the front side of the embroidery frame  50  and the holder plate  90 . The holder plate  90  is a rectangular plate member whose long axis extends in the front-rear direction in a plan view. In other words, the short side direction of the holder plate  90  is the left-right direction. The long side direction of the holder plate  90  is the front-rear direction of the holder plate  90 . The side of the holder plate  90  on which a color reference member  93  that will be described later is provided is the front side of the holder plate  90 . The embroidery frame  50  of which an example is shown in  FIG. 1  includes an inner frame  51  and an outer frame  52  and is an embroidery frame of a known configuration that holds the sewing workpiece (not shown in the drawings) by using the inner frame  51  and the outer frame  52  to clamp it. As shown in  FIGS. 7 and 8 , the embroidery frame  50  is provided with a mounting portion  53 , four engaging portions  54 , and three engagement holes  55 . The mounting portion  53  is configured such that it can be removably mounted on the moving mechanism  40  of the sewing machine  1 . In the present embodiment, a detected portion  56  is provided on the mounting portion  53 , as shown in  FIG. 7 . The detected portion  56  has a shape that is particular to the type of the embroidery frame  50 . In a case where the embroidery frame  50  is mounted on the moving mechanism  40 , the sewing machine  1  is able to specify the type of the embroidery frame  50  based on the shape of the detected portion  56  of the mounting portion  53 , which is detected by a detector  36  (refer to  FIG. 16 ) that will be described later. The four engaging portions  54  and the three engagement holes  55  engage with the holder plate  90  that is mounted on the embroidery frame  50 . 
     As shown in  FIGS. 1, 7, and 8 , the holder plate  90  can be mounted on the embroidery frame  50 . The holder plate  90  is used in a case where an image of a sheet-shaped object, for example, will be captured by the image sensor  35 . The sheet-shaped object may be a paper, a work cloth, or a resin sheet, for example. As shown in  FIGS. 4 to 6 , the holder plate  90  is mainly provided with a planar portion  91 , four engaging portions  92 , three engaging portions  99 , the color reference member  93 , six magnetic bodies  95 , an indicator portion  97 , a base line  98 , and six magnets  100  (refer to  FIG. 7 ). To facilitate the explanation, the magnets  100  are not shown in  FIGS. 4 and 5 . The planar portion  91  has a surface  911  that is planar. As shown in  FIGS. 5 and 6 , the planar portion  91  in the present embodiment has a surface  912  that is also planar on the opposite side from the surface  911 . The four engaging portions  92  and the three engaging portions  99  are able to engage with the embroidery frame  50  that is mounted on the sewing machine  1 . More specifically, the four engaging portions  92  are notches that are provided in central portions of each of the four sides of the rectangular holder plate  90  and that extend toward the center of the holder plate  90 . Each one of the three engaging portions  99  is a protruding portion that is circular in a bottom view and that projects downward from the bottom face of the holder plate  90 . Two of the three engaging portions  99  are provided on the front side of the bottom face of the holder plate  90 , and one of the three engaging portions  99  is provided on the rear side of the bottom face of the holder plate  90 . 
     The color reference member  93  is a member that serves as a color reference. The color reference member  93  includes a white color reference member  931  that serves as a reference for the color white and a black color reference member  932  that serves as a reference for the color black. In the present embodiment, each one of the white color reference member  931  and the black color reference member  932  is a known reflective plate whose surface is planar. The color reference member  93  may be formed by printing coatings of the specified colors on the planar portion  91 , and may also be formed by affixing to the planar portion  91  a reflective tape material of the specified colors. Each one of the white color reference member  931  and the black color reference member  932  lies on the same plane as the surface  911  of the planar portion  91  and is positioned to the outside of an image capture object range R 1 . More specifically, each one of the white color reference member  931  and the black color reference member  932  is provided such that it extends in the short side direction (the left-right direction) of the holder plate  90  at one end (the front end) of the holder plate  90  in the long side direction. Each one of the white color reference member  931  and the black color reference member  932  is provided within an image capture enabled range for the image sensor  35 . The image capture enabled range for the image sensor  35  is determined by an image capture range of the image sensor  35 , a movement enabled range for the moving mechanism  40 , the size of the embroidery frame or the holder member, and the like. The image capture object range R 1  is a rectangular range that is the object of image capture by the image sensor  35  and is the range that is indicated by dashed-two dotted lines in  FIGS. 4 and 7 . The image capture object range R 1  includes the center portion of the surface  911  of the planar portion  91 . In the present embodiment, the image capture object range R 1  is set by the sewing machine  1  within the image capture enabled range for the image sensor  35 , in accordance with the types of the embroidery frame and the holder member, based on data that are stored in the flash memory  64 . 
     In the present embodiment, each one of the white color reference member  931  and the black color reference member  932  is rectangular, with a smaller surface area than that of the image capture object range R 1 , and they are disposed adjacent to one another. The lengths of the white color reference member  931  and the black color reference member  932  in the long side direction (the left-right direction) are the same as the length of the image capture object range R 1  in the short side direction (the left-right direction). Furthermore, the lengths of the white color reference member  931  and the black color reference member  932  in the short side direction (the front-rear direction) are lengths that are set by taking into consideration the image capture range of the image sensor  35 . 
     Each one of the six magnetic bodies  95  is an iron plate that is circular in a plan view. Each of the magnetic bodies  95  is disposed inside a recessed portion  94  that is provided in the surface  911  and is circular in a plan view, and is embedded in the planar portion  91 . In other words, the top face of each of the magnetic bodies  95  is either even with the surface  911  or slightly below the surface  911  and does not protrude above the surface  911 . In the present embodiment, each one of the six magnetic bodies  95  is disposed in a position that coincides with a portion of the boundary of the image capture object range R 1  within the surface  911  of the planar portion  91 . Four of the six magnetic bodies  95  are disposed at the four corners of the rectangular image capture object range R 1 . The remaining two of the six magnetic bodies  95  are disposed in the centers of the two long sides of the rectangular image capture object range R 1 . As shown in  FIG. 7 , the holder plate  90  is provided with the six magnets  100 , which correspond to the individual magnetic bodies  95 . A sheet-shaped object, such as a rectangular paper  180  on which a  FIG. 200  is drawn, for example, can be affixed to the holder plate  90  by the six sets of the magnetic bodies  95  and the magnets  100 . That is, the six sets of the magnetic bodies  95  and the magnets  100  are configured to affix an object that has been placed on the planar portion  91 . 
     The indicator portion  97  is provided in at least the perimeter portion of the planar portion  91 . In the present embodiment, the indicator portion  97  includes eight indicators  96  that are positioned to the outside of the magnetic bodies  95  (in the same plane as the surface  911  and farther from the center of the holder plate  90  than are the magnetic bodies  95 ). Each one of the indicators  96  indicates the positions of the magnetic bodies  95  that are embedded in the planar portion  91 . Two of the eight indicators  96  are recessed portions that are provided such that they extend from one edge (the rear edge) toward the other edge (the front edge) in the long side direction of the holder plate  90 , and they indicate the positions of the magnetic bodies  95  in the long side direction of the holder plate  90 . Three of the eight indicators  96  are recessed portions that are provided such that they extend from one edge (the left edge) toward the other edge (the right edge) in the short side direction of the holder plate  90 , and they indicate the positions of the magnetic bodies  95  in the short side direction of the holder plate  90 . Three of the eight indicators  96  are recessed portions that are provided such that they extend from one edge (the right edge) toward the other edge (the left edge) in the short side direction of the holder plate  90 , and they indicate the positions of the magnetic bodies  95  in the short side direction of the holder plate  90 . Because the indicator portion  97  is positioned to the outside of the magnetic bodies  95 , cases occur in which, depending on the size of the sheet-shaped object, the indicator portion  97  is not covered by the sheet-shaped object, even if the magnetic bodies  95  are covered by the sheet-shaped object. In these cases, the user is able to specify the positions of the six magnetic bodies  95  based on the positions of the indicators  96  that indicate the positions in the short side direction of the holder plate  90  and on the positions of the indicators  96  that indicate the positions in the long side direction of the holder plate  90 . 
     The base line  98  is a guide for placing an object on the surface  911  of the planar portion  91 . In the present embodiment, the base line  98  is a straight line segment that extends along the outline of the image capture object range R 1 . 
     As shown in  FIG. 7 , when the holder plate  90  has been mounted on the embroidery frame  50 , the four engaging portions  92  engage with the corresponding four protruding engaging portions  54  of the embroidery frame  50 . As shown in  FIG. 8 , when the holder plate  90  has been mounted on the embroidery frame  50 , the three engaging portions  99  engage with the corresponding three engagement holes  55  of the embroidery frame  50 , which are through-holes in the up-down direction and are circular in a bottom view. The holder plate  90  is positioned in relation to the embroidery frame  50  and locked in place by these engagements. When the embroidery frame  50  on which the holder plate  90  has been mounted is mounted on the moving mechanism  40 , the surface  911  of the holder plate  90  is approximately parallel to the bed  11 . The planar portion  91  is disposed on the top side of the needle plate  21  and below the needle bar  6  and the presser foot  9 . Furthermore, as shown in  FIG. 8 , a rectangular sliding sheet  57  whose long axis extends in the long side direction of the embroidery frame  50  is provided on the underside of the right edge of the outer frame  52  of the embroidery frame  50 . The sliding sheet  57  is a sheet member that has been processed to give its surface a low coefficient of friction. The sliding sheet  57  is provided such that it protrudes slightly from the surface of the underside of the outer frame  52 . The amount that the sliding sheet  57  protrudes is determined by taking into consideration the distance between the embroidery frame  50 , which is mounted on the moving mechanism  40 , and one of the bed  11  and the needle plate  21 . Therefore, when the embroidery frame  50  has been mounted on the moving mechanism  40 , the sliding sheet  57  is in a state of contact with the top face of the one of the bed  11  and the needle plate  21 . When the embroidery frame  50  has been mounted on the moving mechanism  40 , one long side of the embroidery frame  50  is supported by the mounting portion  53 , and the other long side of the embroidery frame  50  is supported by the sliding sheet  57 . The embroidery frame  50  can more easily keep horizontal the surface of the planar portion  91  that is mounted on the embroidery frame  50  than would be possible if the sliding sheet  57  were not provided on the embroidery frame  50 . When the moving mechanism  40  moves the embroidery frame  50 , the moving mechanism  40  is able to move the embroidery frame  50  smoothly in a state of low friction resistance, because the sliding sheet  57  moves while in contact with the top face of the one of the bed  11  and the needle plate  21 . 
     A holder member  120  that can be mounted on the moving mechanism  40  will be explained with reference to  FIGS. 9 to 11 . The left-right direction, the top side, and the bottom side in  FIG. 9  respectively define the left-right direction, the rear side, and the front side of the holder member  120 . The holder member  120  is a rectangular plate member whose long axis extends in the front-rear direction in a plan view. In other words, the short side direction of the holder member  120  is the left-right direction. The side of the holder member  120  on which a mounting portion  122  that will be described later is provided is the left side of the holder member  120 . The long side direction of the holder member  120  is the front-rear direction of the holder member  120 . The side of the holder member  120  on which a color reference member  123  that will be described later is provided is the front side of the holder member  120 . The holder member  120  of which an example is shown in  FIGS. 9 to 11  is used in a case where an image of a sheet-shaped object, for example, will be captured by the image sensor  35 . The configuration of the holder member  120  is similar to the configuration of the holder plate  90 , so explanations of elements that are the same will be simplified. Note that the configuration of the holder member  120  omits the sliding sheet on the underside. 
     As shown in  FIGS. 9 to 11 , the holder member  120  is mainly provided with a planar portion  121 , the mounting portion  122 , the color reference member  123 , six magnetic bodies  125 , an indicator portion  127 , a base line  128 , and six magnets  130  (refer to  FIG. 2 ). The planar portion  121  has a surface  133  that is planar and has a rectangular shape in a plan view. As shown in  FIGS. 10 and 11 , the planar portion  121  in the present embodiment has a surface  134  that is also planar on the opposite side from the surface  133 . The mounting portion  122  is provided approximately in the center of one long side (the left side) of the perimeter portion of the planar portion  121  and is a rectangular component in a plan view whose long axis extends in the long side direction of the planar portion  121 . The mounting portion  122  supports the planar portion  121  and is configured such that it can be removably mounted on the moving mechanism  40  of the sewing machine  1 . In the present embodiment, a detected portion  129  is provided on the mounting portion  122 . The detected portion  129  has a shape that is particular to the type of the holder member  120  and that is different from the shape of the detected portion  56  that is provided on the mounting portion  53  of the embroidery frame  50 . Therefore, when the holder member  120  has been mounted on the moving mechanism  40 , the sewing machine  1  is able to specify that the holder member  120  has been mounted, based on the shape of the detected portion  129  that is detected by the detector  36 , which will be described later. 
     The color reference member  123  is a member that serves as a color reference. The color reference member  123  is located in the perimeter portion of the planar portion  121 , at one end of the holder member  120  in the long side direction, to the outside (on the front side) of an image capture object range R 2 , which is bounded by the base line  128 . In the same manner as the color reference member  93 , the color reference member  123  includes a white color reference member  131  that serves as a reference for the color white and a black color reference member  132  that serves as a reference for the color black. The lengths of the white color reference member  131  and the black color reference member  132  in the long side direction (the left-right direction) are the same as the length of the image capture object range R 2  in the short side direction. Furthermore, the lengths of the white color reference member  131  and the black color reference member  132  in the short side direction (the front-rear direction) are lengths that are set by taking into consideration the image capture range of the image sensor  35 . 
     Each one of the six magnetic bodies  125  is an iron plate that is circular in a plan view. In the same manner as the magnetic bodies  95 , each of the magnetic bodies  125  is embedded inside a recessed portion  124  that is provided in the surface  133  and is circular in a plan view. The holder member  120  is provided with the six magnets  130  (refer to  FIG. 2 ), which respectively correspond to the magnetic bodies  125 . A sheet-shaped object can be affixed to the holder member  120  by the six sets of the magnetic bodies  125  and the magnets  130 . In other words, the six sets of the magnetic bodies  125  and the magnets  130  are configured such that they fix in place an object that is placed on the planar portion  121 . 
     The indicator portion  127  is provided in at least the perimeter portion of the planar portion  121 . In the same manner as the indicator portion  97 , the indicator portion  127  is provided with eight indicators  126 . Each one of the eight indicators  126  indicates the positions of the magnetic bodies  125  that are embedded in the planar portion  121 . 
     The base line  128  is a guide for placing an object on the surface  133  of the planar portion  121 . In the present embodiment, the base line  128  is a straight line segment that extends along the outline of the rectangular image capture object range R 2 . When the holder member  120  has been mounted on the moving mechanism  40 , the surface  133  of the holder member  120  is approximately parallel to the bed  11 . The planar portion  121  is disposed on the top side of the needle plate  21  and below the needle bar  6  and the presser foot  9 . 
     A holder member  150  that can be mounted on the moving mechanism  40  will be explained with reference to  FIGS. 12 to 15 . The left-right direction, the top side, and the bottom side in  FIG. 12  respectively define the left-right direction, the rear side, and the front side of the holder member  150 . The holder member  150  is a rectangular plate member whose long axis extends in the front-rear direction in a plan view. In other words, the short side direction of the holder member  150  is the left-right direction. The side of the holder member  150  on which a mounting portion  152  that will be described later is provided is the left side. The long side direction of the holder member  150  is the front-rear direction of the holder member  150 . The side of the holder member  150  on which a color reference member  153  that will be described later is provided is the rear side. The holder member  150  of which an example is shown in  FIGS. 12 to 15  is used in a case where an image of a sheet-shaped object, for example, will be captured by the image sensor  35 . The configuration of the holder member  150  is similar to the configurations of the holder plate  90  and the holder member  120 , so explanations of elements that are similar will be simplified. 
     As shown in  FIGS. 12 to 15 , the holder member  150  is mainly provided with a planar portion  151 , the mounting portion  152 , a protective plate  155 , the color reference member  153 , a raised portion  154 , and four magnets  160  (refer to  FIG. 15 ). The planar portion  151 , the mounting portion  152 , the protective plate  155 , and the raised portion  154  are formed as a single unit from a resin material. The planar portion  151  has a surface  163  that is planar and is rectangular in a plan view. A drawing area  158  is an area that is rectangular in a plan view and includes a center portion of the surface  163 . The drawing area  158  is formed by a plate  165  that is made of a magnetic material (for example, iron). The plate  165  has been given a surface treatment that makes it possible to do at least one of drawing with a writing instrument (for example, a special pen) and erasing with an erasing instrument. Specifically, the surface of the plate  165  is a whiteboard that has been coated with a fluorine resin, for example. The user is able to perform drawing with a writing instrument and erasing with an erasing instrument in the drawing area  158  of the plate  165 . The drawing area  158  is congruent with an image capture object range that is set in a case where the holder member  150  is mounted on the sewing machine  1 . A recessed portion (not shown in the drawings) with which the plate  165  engages is formed in the planar portion  151 . The depth of the recessed portion is approximately equal to the thickness of the plate  165 . The back face of the plate  165  adheres to the recessed portion of the planar portion  151 , affixing the plate  165  to the planar portion  151 . Furthermore, as shown in  FIG. 14 , a plurality of reinforcing ribs are formed in a lattice pattern on the back face of the planar portion  151 . 
     The mounting portion  152  is provided approximately in the center of one long side of the perimeter portion of the planar portion  151  and is a rectangular component in a plan view whose long axis extends in the long side direction of the planar portion  151 . The mounting portion  152  supports the planar portion  151  and is configured such that it can be removably mounted on the moving mechanism  40  of the sewing machine  1 . A detected portion  159  is provided on the mounting portion  152 . The detected portion  159  has a shape that is particular to the type of the holder member  150 . Therefore, when the holder member  150  has been mounted on the moving mechanism  40 , the sewing machine  1  is able to specify that the holder member  150  has been mounted, based on the shape of the detected portion  159  that is detected by the detector  36 , which will be described later. 
     The protective plate  155  is a component that is provided in order to prevent the holder member  150  from being mounted by mistake on a sewing machine that is not provided with the image sensor  35 . The protective plate  155  is a component that protrudes from the outer edge of the mounting portion  152 , parallel to the surface  163  of the planar portion  151 . Specifically, the protective plate  155  includes a portion that extends farther to the left than the left edge of the mounting portion  152  and a portion that extends farther to the rear than the rear edge of the mounting portion  152 . When the user mounts the holder member  150  on a sewing machine, the user moves the mounting portion  152  of the holder member  150  toward the rear from a state in which the holder member  150  is disposed in front of the sewing machine, inserting the mounting portion  152  into the right side face of a moving mechanism of the sewing machine. The holder member  150  is configured such that, in a case where the user tries to mount the holder member  150  on a sewing machine that is not provided with the image sensor  35 , the protective plate  155  interferes with the moving mechanism of the sewing machine, and the mounting portion  152  cannot be inserted into the moving mechanism. In contrast, in a case where the user mounts the holder member  150  on the sewing machine  1  of the present embodiment, which is provided with the image sensor  35 , the protective plate  155  does not interfere with the moving mechanism  40 , and the mounting portion  152  can be inserted into the moving mechanism  40 . 
     The color reference member  153  is a member that serves as a color reference. The color reference member  153  is located in the perimeter portion of the planar portion  151 , at one end of the holder member  150  in the long side direction, to the outside (on the rear side) of the drawing area  158 . In the same manner as the color reference member  93 , the color reference member  153  includes a white color reference member  161  that serves as a reference for the color white and a black color reference member  162  that serves as a reference for the color black. The white color reference member  161  and the black color reference member  162  are each rectangular in a plan view, and their lengths in the long side direction (the left-right direction) are the same as the length of an image capture object range R 3  in the short side direction. The lengths of the white color reference member  161  and the black color reference member  162  in the short side direction (the front-rear direction) are lengths that are set by taking into consideration the image capture range of the image sensor  35 . 
     The raised portion  154  is provided on the planar portion  151  and protrudes higher than the surface of the color reference member  153  in at least a portion of the perimeter of the color reference member  153 . The raised portion  154  surrounds the entire perimeter of the color reference member  153  at a specified width (for example, one millimeter). The height of the raised portion  154  may be one millimeter, for example. 
     As shown in  FIG. 15 , each of the four magnets  160  is a thin plate-shaped magnet that is rectangular in a plan view. The sticking of the magnets  160  to the plate  165  makes it possible for a sheet-shaped object such as a paper  190 , for example, to be affixed to the holder member  150 . In other words, the four magnets  160  and the plate  165  are configured to fix in place an object that is placed in the drawing area  158  (the image capture object range) of the planar portion  151 . Because the magnets  160  are disposed in the drawing area  158 , it is preferable for the thicknesses of the magnets  160  to be such that the magnets  160  will not interfere with the presser foot  9  when the holder member  150  is moved by the moving mechanism  40 . It is therefore preferable for the thicknesses of the magnets  160  to be fairly thin, such as one millimeter, for example. The sizes of the individual magnets  160  are set as desired by taking into consideration the shape, the size, and the like of the plate  165 , and may be 90 millimeters by 15 millimeters, for example. 
     When the holder member  150  has been mounted on the moving mechanism  40 , the surface  163  of the holder member  150  is approximately parallel to the bed  11 . The planar portion  151  is disposed on the top side of the needle plate  21  and below the needle bar  6  and the presser foot  9 . As shown in  FIGS. 13 and 14 , a rectangular sliding sheet  157  whose long axis extends in the long side direction of the holder member  150  is provided on the right edge of a back face  164  of the holder member  150 . The sliding sheet  157  is a sheet member that has been processed to give its surface a low coefficient of friction. The sliding sheet  157  is provided such that it protrudes slightly from the surface of the underside of the holder member  150 . The amount that the sliding sheet  157  protrudes is determined by taking into consideration the distance between the holder member  150  and one of the bed  11  and the needle plate  21 . When the holder member  150  has been mounted on the moving mechanism  40 , the sliding sheet  157  is in a state of contact with the top face of the one of the bed  11  and the needle plate  21 . When the holder member  150  has been mounted on the moving mechanism  40 , one edge of the holder member  150  in the long side direction is supported by the mounting portion  152 , and the other edge of the holder member  150  in the long side direction is supported by the sliding sheet  157 . The holder member  150  can more easily keep horizontal the surface  163  of the planar portion  151  than would be possible if the sliding sheet  157  were not provided on the holder member  150 . When the moving mechanism  40  moves the holder member  150 , the moving mechanism  40  is able to move the holder member  150  smoothly in a state of low friction resistance, because the sliding sheet  157  moves while in contact with the top face of one of the bed  11  and the needle plate  21 . 
     An electrical configuration of the sewing machine  1  will be explained with reference to  FIG. 16 . The sewing machine  1  is provided with the CPU  61  and with a ROM  62 , the RAM  63 , the flash memory  64 , and an input/output interface (I/O)  66 , each of which is connected to the CPU  61  by a bus  65 . 
     The CPU  61  performs main control of the sewing machine  1  and, in accordance with various types of programs that are stored in the ROM  62 , performs various types of computations and processing that are related to image capture and sewing. The ROM  62  is provided with a plurality of storage areas that include a program storage area, although they are not shown in the drawings. Various types of programs for operating the sewing machine  1  are stored in the program storage area. 
     Storage areas that store computation results from computational processing by the CPU  61  are provided in the RAM  63  as necessary. Various types of parameters and the like for the sewing machine  1  to perform various types of processing are stored in the flash memory  64 . Drive circuits  71  to  74 , the touch panel  26 , the start/stop switch  29 , the image sensor  35 , and the detector  36  are connected to the I/O  66 . The detector  36  is configured to detect the type of the embroidery frame or the holder member that is mounted on the moving mechanism  40 , and to output a detection result. 
     The sewing machine motor  81  is connected to the drive circuit  71 . The drive circuit  71  drives the sewing machine motor  81  in accordance with a control signal from the CPU  61 . As the sewing machine motor  81  is driven, the needle bar up-down drive mechanism  34  (refer to  FIG. 3 ) is driven through the drive shaft (not shown in the drawings) of the sewing machine  1 , and the needle bar  6  is moved up and down. The X axis motor  83  is connected to the drive circuit  72 . The Y axis motor  84  is connected to the drive circuit  73 . The drive circuits  72  and  73  respectively drive the X axis motor  83  and the Y axis motor  84  in accordance with control signals from the CPU  61 . As the X axis motor  83  and the Y axis motor  84  are driven, the embroidery frame  50  is moved in the left-right direction (the X axis direction) and the front-rear direction (the Y axis direction) by amounts that correspond to the control signals. By driving the LCD  15  in accordance with a control signal from the CPU  61 , the drive circuit  74  causes the LCD  15  to display an image. 
     The operation of the sewing machine  1  will be explained briefly. During embroidery sewing in which the embroidery frame  50  is used, the needle bar up-down drive mechanism  34  (refer to  FIG. 3 ) and the shuttle mechanism (not shown in the drawings) are driven in conjunction with the moving of the embroidery frame  50  in the left-right direction (the X axis direction) and the front-rear direction (the Y axis direction) by the moving mechanism  40 . These operations cause an embroidery pattern to be sewn, by the sewing needle  7  that is mounted on the needle bar  6 , in the sewing workpiece that is held in the embroidery frame  50 . When an ordinary utility pattern that is not an embroidery pattern is sewn, the sewing is performed as the sewing workpiece is moved by the feed dog (not shown in the drawings), in a state in which the moving mechanism  40  has been removed from the bed  11 . When an image of an object is captured using any one of the embroidery frame  50 , the holder member  120 , and the holder member  150 , the one of the embroidery frame  50 , the holder member  120 , and the holder member  150  that is mounted on the moving mechanism  40  is moved in the left-right direction (the X axis direction) and the front-rear direction (the Y axis direction) by the moving mechanism  40 . The image sensor  35  captures the image within the image capture range. In this manner, the image data are created for an image that has been captured of the object, the color reference member, and the like that are within the image capture range. 
     When any one of the embroidery frame  50  on which the holder plate  90  is mounted, the holder member  120 , and the holder member  150  has been mounted on the moving mechanism  40  of the sewing machine  1 , the sewing machine  1  is able to perform the processing that is hereinafter described. Specifically, because the image sensor  35  of the sewing machine  1  has the AWB, a control portion of the sewing machine  1  is able to adjust the white balance of image data based on the image data that have been captured for the color reference members  93 ,  123 ,  153 . Because the individual color reference members  93 ,  123 ,  153  respectively include the white color reference members  931 ,  131 ,  161 , the sewing machine  1  is particularly able to adjust the white balance appropriately based on the image data that have been captured for the white color reference members  931 ,  131 ,  161 . Further, because the image sensor  35  also has the MWB, the sewing machine  1  is able to define the WB values when an image of an object is captured as being the same as the WB values when images are captured of the color reference members  93 ,  123 ,  153 . Because the image of the object is captured in a state in which the object is disposed along a surface that is planar, the sewing machine  1  is able to acquire image data that describe an image in which deformation of the object that is due to wrinkling, sagging, and the like is reduced. 
     The sewing machine  1  is able to perform color-related correction on the image data (second image data) for a captured image of an object, based on the image data (first image data) for a captured image of any one of the color reference members  93 ,  123 ,  153 . For example, based on the first image data, the sewing machine  1  is able to perform known shading correction on the second image data. In that case, the sewing machine  1  is able to acquire the second image data in which uneven coloring and uneven lighting have been reduced from what they were prior to the correction. 
     An object that is placed on the planar portion  91  can be affixed to the holder plate  90  along the planar surface  911 . An object that is placed on the planar portion  121  can be affixed to the holder member  120  along the planar surface  133 . The holder member  150  is provided with the planar portion  151 , which includes the drawing area  158 , in which writing can be done by a writing instrument. The user can use a writing instrument to freely draw an illustration, a figure, a text character, a symbol, and the like in the drawing area  158 . The plate  165  is a whiteboard that has been given a surface treatment that makes it possible to do drawing with a writing instrument and erasing with an erasing instrument, so the writing with a writing instrument can be done repeatedly. An object that is placed on the planar portion  151  can be affixed to the holder member  150  along the planar surface  163 . With the holder member  150 , the user may draw an illustration and the like in the drawing area  158  and may also draw an illustration and the like on the object. 
     When the embroidery frame  50  with which the holder plate  90  is engaged has been mounted on the sewing machine  1 , which is provided with the moving mechanism  40 , in a case where one of the holder member  120  and the holder member  150  has been mounted, the sewing machine  1  is capable of performing image processing that is hereinafter described. That is, the sewing machine  1  is able to correct image data (the second image data) that have been created by capturing an image of an object, based on image data (the first image data) that have been created by capturing an image of one of the color reference members  93 ,  123 ,  153 . The sewing machine  1  is able to appropriately correct uneven coloring in the second image data that is due to image capture conditions such as brightness and the like. In other words, the holder plate  90  and the holder members  120 ,  150  are more suitable for the creating of the image data by the image sensor  35  of the sewing machine  1  than is the embroidery frame  50 , which simply holds the object. The holder plate  90  and the holder members  120 ,  150  are able to eliminate the burden on the user of preparing a color reference member that is separate from the holder member. 
     The sewing machine  1  on which the holder member  120  is mounted is able to correct the second image data based on the color information in the image data that have been created for a captured image of the white color reference member  131 . The holder member  120  therefore makes it possible for the sewing machine  1  to create the second image data such that the second image data describe the colors of an object more appropriately, particularly white and colors that are close to white. The sewing machine  1  on which the holder member  120  is mounted is able to correct the second image data based on the color information in the image data that have been created for a captured image of the black color reference member  132 . The holder member  120  makes it possible for the sewing machine  1  to create the second image data such that the second image data describe the colors of an object more appropriately. These effects can also be achieved by the sewing machine  1  on which the embroidery frame  50  with which the holder plate  90  is engaged has been mounted and by the sewing machine  1  on which the holder member  150  is mounted. 
     The holder plate  90 , with its simple configuration of the magnets  100  and the magnetic bodies  95 , makes it possible to affix an object along the planar portion  91 , which is planar. The holder member  120 , with its simple configuration of the magnets  130  and the magnetic bodies  125 , makes it possible to affix an object along the planar portion  121 , which is planar. The holder member  150 , with its simple configuration of the magnets  160  and the plate  165 , makes it possible to affix an object along the planar portion  151 , which is planar. Because the holder plate  90  is provided with the indicator portion  97 , the user is able to know the positions of the magnetic bodies  95  that are embedded in the planar portion  91 , even in a state in which an object has been placed on the surface  911  of the planar portion  91 . Therefore, using the magnets  100 , the user is easily able to perform the task of affixing the object along the surface  911  of the planar portion  91 . Because the holder member  120  is provided with the indicator portion  127 , the user is able to know the positions of the magnetic bodies  125  that are embedded in the planar portion  121 , even in a state in which an object has been placed on the surface  133  of the planar portion  121 . Therefore, using the magnets  130 , the user is easily able to perform the task of affixing the object along the surface  133  of the planar portion  121 . 
     The holder plate  90  includes the base line  98 . Therefore, using the base line  98  as a reference, the user is able to place an object in an appropriate position on the surface  911  of the planar portion  91 . The holder member  120  includes the base line  128 . Therefore, using the base line  128  as a reference, the user is able to place an object in an appropriate position on the surface  133  of the planar portion  121 . The appropriate position may be, for example, a position in which the object fits within the image capture object range. 
     When the holder member  120  has been mounted on the sewing machine  1 , the color reference member  123  is disposed farther to the front than is the needle bar  6 . Therefore, in the process by which the holder member  120  is mounted on the sewing machine  1 , the possibility can be reduced that the color reference member  123  will be damaged by coming into contact with the sewing needle  7  that is mounted on the lower end of the needle bar  6  and with the presser foot  9  that is mounted on the lower end of the presser bar  8 . The same sort of effect can also be achieved with the holder plate  90 . In contrast, when the holder member  150  has been mounted on the sewing machine  1 , the color reference member  153  is disposed farther to the rear than is the needle bar  6 , and the drawing area  158  is disposed farther to the front than is the needle bar  6 . Therefore, after the holder member  150  has been mounted on the sewing machine  1 , it is easy for the user to perform the tasks of drawing an illustration or the like in the drawing area  158  with a writing instrument, affixing an object to the drawing area  158 , and adjusting the position of an object in the drawing area  158 . Furthermore, when the user performs these tasks with the color reference member  153  positioned to the rear of the drawing area  158 , the user can avoid touching the color reference member  153 , getting the color reference member  153  dirty, and damaging the color reference member  153  by mistake. 
     The holder member  150  includes the raised portion  154 . The raised portion  154  inhibits the inflicting of damage on the color reference member  153  when the holder member  150  is mounted on the sewing machine  1 , removed from sewing machine  1  and stored, and the like. In a case where the holder member  150  has been mounted on the sewing machine  1 , which is provided with the moving mechanism  40 , the holder member  150  is able to inhibit a decrease in the precision of the processing by the sewing machine  1  that corrects the second image data based on the image data that have been created by capturing an image of the color reference member  153 . 
     The holder member  150  includes the sliding sheet  157 . If the holder member  150  is compared with a known embroidery frame that has approximately the same outside diameter, the holder member  150  is heavier than the embroidery frame by the weight of the planar portion  151 . However, the holder member  150  is provided with the sliding sheet  157  on the back face  164 , on the opposite side from the surface  163  of the planar portion  151 . Accordingly, when the holder member  150  is mounted on the moving mechanism  40  and the sliding sheet  157  is in contact with the top face of the one of the bed  11  and the needle plate  21  of the sewing machine  1 , the holder member  150  is able to move smoothly in a state of low friction resistance. 
     The holder member of the present disclosure is not limited to the embodiments that are described above, and various types of modifications may be made within the scope of the present disclosure. For example, modifications (A) and (B) described below may be made as desired. 
     (A) The configuration of the sewing machine  1  on which the holder member is mounted may be modified as desired. The sewing machine  1  may be an industrial sewing machine, and may also be a multi-needle sewing machine. 
     (B) It is sufficient for the holder plate  90  to be provided with at least the planar portion  91 , the engaging portions  92 , the color reference member  93 , and an affixing portion that is configured to affix an object to the holder plate  90 , while other elements of the holder plate  90  may be omitted as desired, and the configuration of the holder plate  90  may be modified. It is sufficient for the holder member  120  to be provided with at least the planar portion  121 , the mounting portion  122 , the color reference member  123 , and an affixing portion that is configured to affix an object to the holder member  120 , while other elements of the holder member  120  may be omitted as desired, and the configuration of the holder member  120  may be modified. The sizes, the shapes, and the positions of the planar portions  91 ,  121  may be modified as desired, taking into consideration the size of the object, the range of movement of the moving mechanism  40 , the image capture range of the image sensor  35 , and the like. It is sufficient for the engaging portions  92 ,  99  to be able to engage with an embroidery frame that is held by sewing machine  1 , and the shapes, the positions, the number, and the like of the engaging portions  92 ,  99  may be modified as desired. 
     The color reference members  93 ,  123  may each be configured such that they are provided with only one of the white color reference member and the black color reference member. The positions, the sizes, the shapes, and the like of the color reference members  93 ,  123  may be modified as desired. For example, the color reference members may be provided over the entire image capture object ranges of the planar portions  91 ,  121 . In that case, the first image data may be captured in a state in which the object is not affixed to the planar portions  91 ,  121 , that is, in a state in which the color reference members are exposed to the image sensor  35 . The second image data may be captured in a state in which the object is affixed to the planar portions  91 ,  121 , that is, in a state in which the color reference members are not exposed to the image sensor  35 . 
     It is sufficient for an affixing portion to be configured to fix an object in place, and in addition to being at least one set of a magnet and a magnetic body, the affixing portion may also be at least one pair of magnets that are disposed such that they attract one another, and adhesive film, or the like. It is not necessary for the holder member  150  to be provided with the four magnets  160  (refer to  FIG. 2 ). In the holder member  150 , the material of the plate  165  may be modified as desired, and the plate  165  may be formed from a magnet, for example. In a case where the plate  165  is formed from a magnet, it is sufficient for the holder member  150  to be a magnetic body, such as an iron plate or the like, instead of being provided with the magnets  160 . It is sufficient for the indicators  96 ,  126  to be provided in at least the perimeters of the planar portions  91 ,  121 , respectively, and to indicate the positions where the magnetic bodies  95 ,  125  are embedded in the planar portions  91 ,  121 , respectively, and the shapes, the sizes, the positions, the number, and the like of the indicators  96 ,  126  may be modified as desired, in accordance with the image capture object range and the like. It is sufficient for the base lines  98 ,  128  to serve as guides for the placing of an object. It is not necessary for the base lines  98 ,  128  to indicate the image capture object range that is set by the sewing machine  1 . The indicators and the base lines may also be printed marks or raised portions, for example. In the holder member  150 , the sliding sheet  157  may be omitted as desired. The holder member  120  may also be provided with the sliding sheet  157  in the same manner as the holder member  150 . In the holder member  150 , the raised portion  154  may be omitted as desired. The holder plate  90  and the holder member  120  may also be provided with the raised portion  154  in the same manner as the holder member  150 . The raised portion  154  may also be provided in at least a portion of the area around any one of the color reference members  93 ,  123 ,  153 .
