Description

  The present invention relates to a printing image determination system, a printing image determination method, and a printing image determination program.

  As a printing apparatus that performs printing on a medium, for example, an ink jet type printing apparatus that ejects liquid droplets from a head onto the medium is known (for example, see Patent Document 1). Using such a printing apparatus, for example, an image can be formed on a signboard or the like.

Japanese Patent Laying-Open No. 2015-13455

  In recent years, for example, as in the landscape ordinance, use of a predetermined color for an image displayed on a signboard or the like in a certain area or more may be prohibited. When it is determined that such a regulated color is used in the image after the image is formed on the sign, it is necessary to re-form the image on the sign using a color different from the regulated color. Therefore, there is a need for a technique that can grasp before printing whether or not a printing image satisfies a standard based on such use prohibition regulations.

  The present invention has been made in view of the above, and it is possible to easily determine whether a print image satisfies a predetermined standard based on the use prohibition regulation before printing. It is an object to provide a system, a printing image determination method, and a printing image determination program.

  In the printing image determination system according to the present invention, when image data including a printing image to be printed by a printing apparatus is input, the printing image included in the input image data is determined based on a use prohibition regulation. And a control device that outputs a determination result and a display device that displays the determination result output from the control device.

  According to the present invention, the control device determines whether or not the print image satisfies a predetermined standard based on the regulation, and the determination result is displayed on the display device, so the determination result displayed on the display device is confirmed. By doing so, it becomes possible to easily grasp whether or not the printing image satisfies a predetermined standard based on the regulations before printing.

  In the printing image determination system, the predetermined reference based on the use prohibition regulation may be a color.

  Thereby, when the color to be used is regulated by the use prohibition regulation, it can be easily determined whether or not the printing image satisfies the regulation.

  In the printing image determination system, the predetermined reference based on the use prohibition regulation is an area of a region to which the color is added in addition to the color.

  Thereby, when a color and an area are regulated by the use prohibition regulation, it can be easily determined whether or not the printing image satisfies the regulation.

  In the printing image determination system, the control device determines whether the printing image includes a restriction target color as a predetermined reference based on the use prohibition restriction, and the printing image is When determining that the color to be regulated includes the color to be regulated, it is determined whether or not an area ratio with respect to the entire printing image for the region to which the color to be regulated is applied satisfies a predetermined area standard, and the area ratio is the predetermined color When the area standard is not satisfied, it is determined that the printing image does not satisfy the predetermined standard.

  As a result, it is possible to determine whether or not the print image satisfies a predetermined standard based on the color of the print image and the area of the region to which the color is added. Thereby, for example, when the regulated color such as a color prohibited to be used by the landscape regulations and the area ratio where the regulated color is used are regulated, whether or not the printing image satisfies the regulation. It can be easily determined.

  In the printing image determination system, when the control device determines that the printing image does not satisfy the predetermined standard, the control device assigns the region to which the restriction target color is attached to another region. It is displayed on the display device in an emphasized state.

  As a result, it is possible to easily grasp the region determined to not satisfy the predetermined standard in the print image.

  Further, in the printing image determination system, when the control device determines that the printing image does not satisfy the predetermined standard, the control target is applied to the region to which the control target color is attached. A candidate for a color different from the color is displayed on the display device.

  As a result, the user can easily change the color or the like of the area determined to have the restriction target color in the printing image.

  In the printing image determination method according to the present invention, when image data including a printing image to be printed in a printing apparatus is input, the printing image included in the input image data is determined based on a use prohibition regulation. Determining whether or not the above criteria are satisfied, and displaying the determination result on a display device.

  Further, the printing image determination program according to the present invention is configured such that, when image data including a printing image to be printed in a printing apparatus is input, the printing image included in the input image data is prohibited from use. And causing the computer to perform a process of determining whether or not a predetermined criterion based on the above is satisfied.

  According to these inventions, since it is possible to determine whether or not a printing image satisfies a predetermined standard based on regulations and display the determination result on the display device, for example, determination to be displayed on the display device By allowing the user to confirm the result, it is possible to easily determine whether or not the printing image satisfies a predetermined standard based on regulations before printing.

  Hereinafter, embodiments of a printing image determination system, a printing image determination method, and a printing image determination program according to the present invention will be described with reference to the drawings. In addition, this invention is not limited by this embodiment. In addition, constituent elements in the following embodiments include those that can be easily replaced by those skilled in the art or those that are substantially the same.

  FIG. 1 is a diagram illustrating an example of a printing image determination system (hereinafter referred to as a determination system) SYS according to the present embodiment. As shown in FIG. 1, the determination system SYS includes a control device 10, an input device 20, and a display device 30. Note that the input device 20 can input information to the control device 10. In the present embodiment, a configuration in which, for example, a keyboard 21 and a mouse 22 are provided as the input device 20 is described as an example, but the present invention is not limited thereto, and other input devices such as a touch panel may be provided. Further, as the display device 30, for example, a display device such as a liquid crystal display is used, but other display devices may be used.

  The control device 10 is connected to the printing device P and transmits image data including an image for printing to the printing device P. The image data including the print image is in a state created in advance by the user. FIG. 2 is a block diagram illustrating a configuration example of the control device 10. As illustrated in FIG. 2, the control device 10 includes a control unit 11 and a storage unit 12.

  The storage unit 12 includes a color system data storage unit 16 and a reference data storage unit 17. The color system data storage unit 16 stores color data for each color system. As the color system, color data for each color system is stored for color systems such as the CMYK color system, the RGB color system, the Lab color system, the XYZ color system, the Munsell color system, and the like.

  The reference data storage unit 17 stores, as reference data, items related to a predetermined reference based on the use prohibition regulations for printing images. For example, as in the landscape regulations, colors (hue, lightness, saturation) that are prohibited from being used in images displayed on a signboard or the like may be specified in some areas. Further, such a color to be regulated may be used as long as it is equal to or less than a predetermined area ratio with respect to the entire image, but there are cases where use exceeding a predetermined area ratio is prohibited.

  In the program storage unit 18, when image data including a printing image to be printed by the printing apparatus P is input to the control apparatus 10, the printing image included in the input image data is a predetermined one based on the use prohibition regulation. A printing image determination program for causing the control device 10 to perform processing for determining whether or not the standard is satisfied is stored. The program storage unit 18 may store a display program for causing the display device 30 to display the determination result determined by the printing image determination program. Further, the print image determination program may include the display program.

  In the present embodiment, a predetermined reference based on the use prohibition restriction as described above is stored in the storage unit 12 in advance as reference data. When image data including a printing image is input to the control device 10, the control unit 11 compares the image data with the reference data, so that the printing image included in the image data satisfies a predetermined criterion. It is determined whether or not. The control unit 11 includes a color system adjustment unit 13, a color determination unit 14, and an area determination unit 15.

  When the color system of the color in the reference data is different from the color system of the ink color in the printing apparatus P, the color system adjusting unit 13 converts one color system to the other color system. For example, in the landscape regulations as described above, a color to be regulated (regulated color) is set based on the Munsell color system. On the other hand, in the printing apparatus P as in the present embodiment, the ink color is set based on, for example, the CMYK color system or the RGB color system. Therefore, in the present embodiment, the color system adjusting unit 13 converts the color system of the printing apparatus P into the Munsell color system.

  In this case, the color system adjustment unit 13 first converts the color of the ink set in the CMYK color system or the RGB color system into a color of the Lab color system. Thereafter, the color converted to the Lab color system is converted to an XYZ color system. Then, the color converted into the XYZ color system is converted into the Munsell color system. When the color system is converted, the color system adjustment unit 13 uses the color system data stored in the color system data storage unit 16 of the storage unit 12. Thus, by sequentially converting the ink colors set in the CMYK color system or the RGB color system, it is possible to obtain the Munsell color system color corresponding to the ink color with high accuracy.

  The color determination unit 14 determines whether the printing image converted into the Munsell color system includes a restriction target color. In this case, examples of the color to be regulated include a color whose use is prohibited or regulated by the landscape ordinance. Such restriction target colors are stored as reference data in the reference data storage unit 17. The color determination unit 14 compares the color of each pixel of the printing image converted into the Munsell color system and the restriction target color of the reference data, and determines whether or not they are the same color. If the color determination unit 14 determines that both are the same color, the color determination unit 14 determines that the print image includes the restriction target color. If the color determination unit 14 determines that both are not the same color, the color determination unit 14 determines whether the color of each pixel of the print image is a color that approximates the restriction target color.

  When comparing the color of each pixel of the printing image with the restriction target color of the reference data, the color determination unit 14 can compare based on, for example, hue and saturation. For example, depending on the landscape ordinance, there may be a case where a range of saturation is provided in the restriction target color, such as a color whose saturation in a predetermined hue is a certain level or more. In such a case, the color determination unit 14 determines that the two colors to be compared are the same color when the hue and saturation are both the same or within the range.

  When determining that the printing image includes the restriction target color, the area determination unit 15 determines whether the area ratio of the region to which the restriction target color is attached to the entire printing image satisfies a predetermined area criterion. To do. In this case, the area determination unit 15 obtains the number of pixels determined as the restriction target color, and calculates a ratio with respect to all the pixels of the printing image. The area determination unit 15 can determine whether the area ratio satisfies a predetermined area reference value by comparing the calculation result with the area reference value of the reference data. For example, in the landscape ordinance, when it is prohibited to use a regulated color exceeding a predetermined area ratio, the area determination unit 15 determines that the area ratio is a predetermined area when the calculation result is equal to or smaller than the area reference value. It is determined that the standard is satisfied. On the other hand, when the calculation result exceeds the area reference value, the area determination unit 15 determines that the area ratio does not satisfy the predetermined area reference.

  When the area determination unit 15 determines that the area ratio does not satisfy the predetermined area standard, the control unit 11 determines that the printing image does not satisfy the predetermined standard. The control unit 11 outputs a determination result.

  The display device 30 displays the determination result output from the control device 10. FIG. 3 is a diagram illustrating an example of a display screen when the determination result by the control unit 11 is displayed. As illustrated in FIG. 3, the control unit 11 displays the determination result window 40 on the display device 30 after performing the determination. The determination result window 40 includes an image display unit 41, a target area display unit 42, an operation button display unit 43, a color information display unit 44, an overall information display unit 45, and a confirmation button display unit 46. Yes.

  The image display unit 41 displays the printing image IM. The target area display unit 42 displays the name of the determination area where the determination has been made. Although the landscape regulations differ from region to region, in this embodiment, a determination result corresponding to each region is displayed.

  The operation button display unit 43 is used when the reference data is added, changed, deleted, or the like for the region displayed in the target region display unit 42. The operation button display unit 43 deletes the add button 43a for adding the reference data set for the area, the change button 43b for changing the reference data set for the area, and the reference data set for the area. A delete button 43c is displayed.

  For example, when the mouse 22 is used as the input device 20, the add button 43 a, the change button 43 b, and the delete button 43 c displayed on the operation button display unit 43 are selected by moving the mouse cursor and clicking. Further, when a touch panel is used as the input device 20, the input device 20 is selected by touching the target area.

  The color information display unit 44 displays various types of information about the colors determined as the restriction target color by the color determination unit 14 among the colors included in the print image. The color information display unit 44 includes, for example, target color data 44a indicating the color of an area (hereinafter, referred to as a target area IMa) determined to be the same as or approximate to the restriction target color in the printing image IM, Pre-conversion color system data 44b representing the color of the target area IMa in the print image input to the control unit 11 with numerical values of the color system before conversion (CMYK color system or RGB color system), and a Munsell table After-conversion color system data 44c indicating the color of the target area IMa after conversion to the color system, area ratio data 44d indicating the area ratio of the target area IMa in the entire printing image IM, and the target area IMa The restriction content data 44e for is displayed.

  In the example shown in FIG. 3, the target area IMa has an area ratio of 50% of the entire printing image IM, the color of the target area IMa is red, the restriction target color in the use prohibition restriction is red, and the area A case where the standard is 50% or more is given as an example. In this case, in the area A, when a printing image in which the red area has an area ratio of 50% or more of the entire area is printed on a signboard or the like, the signboard is subject to regulation.

  In such an example, the determination result window 40 includes numerical values indicating red (“C0, M100, Y100, K0”, “4 R4 / 14”) as the pre-conversion color system data 44b and the post-conversion color system data 44c. ) Is displayed. Further, the area ratio data 44d indicates that the area ratio of the target region IMa is 50%. Further, the restriction content data 44e displays that it is a prohibited color.

  In the color information display unit 44, when the control unit 11 determines that the print image does not satisfy the predetermined standard, the color information display unit 44 may display a color candidate different from the restriction target color. In this case, the control unit 11 extracts and displays a color different from the restriction target color among the colors stored in the reference data storage unit 17. Examples of colors to be extracted include, but are not limited to, colors that have the same hue and whose saturation is not regulated.

  In addition, in the determination result window 40, a highlight display selection unit 44f is provided below the color information display unit 44. The highlight display selection unit 44f selects whether or not to highlight the target region IMa including the color displayed on the color information display unit 44 with respect to other regions. For example, by checking the highlighting selection unit 44f, the target area IMa is highlighted with respect to other areas. In this case, the highlighted display with respect to another area | region includes displaying in a different aspect from another area | region. For example, it includes display forms such as blinking the target area IMa, displaying the outline of the target area IMa thick or dark, and displaying the color of the target area IMa different from other areas.

  The overall information display unit 45 displays information other than information related to color, for example, information related to the area ratio of the target region IMa. Note that information other than the color and area ratio may be displayed on the overall information display unit 45. The confirmation button display unit 46 displays a confirmation button. The determination result window 40 can be closed by selecting the confirmation button.

  FIG. 4 is a diagram showing an example of a screen displayed when the add button 43a of the operation button display unit 43 is selected in the determination result window 40 shown in FIG. As shown in FIG. 4, when the add button 43 a is selected, the control unit 11 causes the display device 30 to display a reference data setting window 50 for setting reference data for each region.

  The reference data setting window 50 includes restriction type selection units 51, 52, and 53. The restriction type selection unit 51 selects whether to set a restriction target color. By checking the restriction type selection unit 51, it becomes possible to set the restriction target color and the area ratio. In the restriction type selection unit 51, the restriction target color setting unit 54 can set the saturation and hue of the restriction target color. The saturation of the restriction target color can be set, for example, by inputting a numerical value to the saturation setting unit 54a. The hue of the restriction target color can be set by adding, changing, or deleting the hue by the hue setting unit 54b.

  In addition, the individual setting selection unit 54c can individually set the saturation for each hue. FIG. 5 is a diagram illustrating an example of a screen displayed when the individual setting selection unit 54c individually sets the saturation for each hue in the reference data setting window 50 illustrated in FIG. As shown in FIG. 5, when the add button of the individual setting selection unit 54c is selected, an individual setting window 60 is displayed. The individual setting window 60 includes a hue selection unit 61, a saturation input unit 62, and operation buttons 63. The hue selection unit 61 can select a hue to be set from a plurality of candidates. The saturation input unit 62 inputs the saturation to be set. The operation button 63 has an add button 63a and a cancel button 63b. When the hue is selected by the hue selection unit 61 and the add button 63a is selected in the state where the saturation is input by the saturation input unit 62, the selected hue and the input saturation are added as reference data for the restriction target color. . The cancel button 63 b cancels the selection content in the hue selection unit 61 and the input content in the saturation input unit 62. The saturation and hue setting results set in this way are displayed, for example, on the setting result display unit 54d shown in FIG. Further, the area ratio can be set by the area ratio setting unit 55. The area ratio setting unit 55 can be set by checking the setting selection unit 55a and inputting a numerical value to the area ratio input unit 55b.

  Further, as shown in FIG. 4, the restriction type selection unit 52 selects whether or not to set a prohibited color. The prohibited color is a regulated color that is regulated regardless of the area ratio when it is included in the printing image IM. The prohibited color can be set by checking the restriction type selection unit 52. In the restriction type selection unit 52, the prohibited color setting unit 56 can set the saturation and hue of the prohibited color. For example, the saturation of the prohibited color can be set by inputting a numerical value to the saturation setting unit 56a. The hue of the forbidden color can be set by adding, changing, or deleting the hue by the hue setting unit 56b. Similarly to the restriction target color, the individual setting selection unit 56c can individually set the saturation for each hue. The saturation and hue setting results are displayed, for example, on the setting result display unit 56d.

  The restriction type selection unit 53 sets whether to include raster data such as photographs and paintings as restriction objects. Depending on the region, raster data may be subject to regulation. Raster data can be regulated by checking the regulation type selection unit 53. In this case, the control unit 11 may determine whether or not the printing image IM is raster data by determining whether or not the printing image IM has a data format unique to raster data. Further, image data of raster data is stored in the storage unit 12, and the control unit 11 compares the print image IM with the image data in the storage unit 12 to determine whether the print image IM is raster data. It may be determined.

  FIG. 6 is a flowchart illustrating an example of the printing image determination method according to the present embodiment. As shown in FIG. 6, the image data is input to the control device 10 when the user creates image data including the print image IM and inputs the image data to the control device 10 (step S <b> 10). When the image data is input, the control unit 11 determines whether or not the printing image IM included in the input image data satisfies a predetermined standard based on the use prohibition regulation (step S20). In step S20, the control unit 11 determines whether or not the printing image IM satisfies a predetermined standard by comparing the printing image IM and the reference data.

  FIG. 7 is a flowchart illustrating an example of the determination step S20. As shown in FIG. 7, the color system adjustment unit 13 determines whether the color system of the printing image IM included in the input image data matches the color system of the restriction target color set as the reference data. If they are different, the color system of the printing image IM is converted to the color system of the restriction target color (step S21). In step S21, the color system adjusting unit 13 converts the CMYK color system or the RGB color system of the printing image IM into the Munsell color system of the restriction target color.

  After the color system is converted, the color determination unit 14 determines whether or not the color of the printing image IM after the conversion of the color system satisfies a predetermined standard (step S22). In step S <b> 22, the color determination unit 14 compares the color of each pixel of the printing image after converting the color system and the restriction target color of the reference data, and both are the same color (or similar color). It is determined whether or not. When both are not the same color (or similar color), the color determination unit 14 determines that the color of the printing image IM after converting the color system satisfies a predetermined standard. When both are the same color (or similar color), the color determination unit 14 determines that the color of the printing image IM after converting the color system does not satisfy a predetermined standard.

  In step S22, when it is determined that the color of the printing image IM after conversion of the color system does not satisfy the predetermined standard (No in step S22), the area determination unit 15 is assigned the restriction target color. It is determined whether or not the area ratio of the target area IMa with respect to the entire printing image IM satisfies a predetermined area standard (step S23). In step S23, the area determination unit 15 obtains the number of pixels determined as the restriction target color, and calculates a ratio with respect to all the pixels of the printing image IM. The area determination unit 15 determines whether or not the area ratio satisfies a predetermined area reference value by comparing the calculation result with the area reference value of the reference data.

  When it is determined in step S22 that the color of the printing image IM after conversion of the color system satisfies the predetermined standard (Yes in step S22), or the target area IMa to which the restriction target color is added in step S23 When it is determined that the area ratio with respect to the entire print image IM satisfies the predetermined area standard (Yes in step S23), the control unit 11 restricts the use of the print image IM included in the input image data. It is determined that a predetermined criterion based on the above is satisfied (Yes in step S24 and step S20).

  On the other hand, when it is determined in step S23 that the area ratio of the target area IMa to which the restriction target color is added to the entire printing image IM does not satisfy the predetermined area standard (No in step S23), the control unit 11 Then, it is determined that the printing image IM included in the input image data does not satisfy a predetermined standard based on the use prohibition regulation (No in Step S25 and Step S20).

  When it is determined in step S20 that the predetermined standard is satisfied (step S24, Yes in step S20), as illustrated in FIG. 6, the control unit 11 displays on the display device 30 that the standard is satisfied ( Step S30). In step S30, the control unit 11 displays, for example, that the printing image IM satisfies the standard in the overall information display unit 45 of the determination result window 40 shown in FIG.

  Moreover, when it determines with not satisfy | filling a predetermined reference | standard in step S20 (step S25, No of step S20), the control part 11 displays on the display apparatus 30 that the reference | standard is not satisfy | filled (step S40). In step S40, the control unit 11 displays, for example, information on the color of the target area IMa on the color information display unit 44 of the determination result window 40 shown in FIG.

  As described above, in the printing image determination system SYS according to the present embodiment, when image data including the printing image IM to be printed in the printing apparatus P is input, the printing image included in the input image data. It is determined whether or not IM satisfies a predetermined standard based on the use prohibition regulation, and includes a control device 10 that outputs a determination result and a display device 30 that displays the determination result output from the control device 10.

  In the printing image determination method according to the present embodiment, when image data including the printing image IM to be printed in the printing apparatus P is input, the printing image IM included in the input image data is prohibited from being used. It includes determining whether or not a predetermined standard based on regulations is satisfied, and displaying the determination result on the display device 30.

  The printing image determination program according to the present embodiment prohibits the use of the printing image IM included in the input image data when the image data including the printing image IM to be printed in the printing apparatus P is input. Causes the computer to perform processing for determining whether or not a predetermined standard based on regulations is satisfied.

  According to the present invention, the control device 10 determines whether or not the printing image IM satisfies a predetermined standard based on the regulation, and the determination result is displayed on the display device 30. By confirming the determination result, it is possible to easily grasp whether or not the printing image IM satisfies a predetermined standard based on regulations before printing.

  In the printing image determination system SYS, the predetermined reference based on the use prohibition regulation is color. Thereby, when the color to be used is regulated by the use prohibition regulation, it can be easily determined whether or not the printing image IM satisfies the regulation.

  In the printing image determination system SYS, the predetermined reference based on the use prohibition regulation is an area of a region to which the color is added in addition to the color. Thereby, when a color and an area are regulated by the use prohibition regulation, it can be easily determined whether or not the printing image satisfies the regulation.

  In the printing image determination system SYS according to the present embodiment, the control device 10 determines whether the printing image IM includes a restriction target color as a predetermined reference based on the use prohibition restriction, and the printing image. When it is determined that the IM includes the restriction target color, it is determined whether or not the area ratio of the target area IMa to which the restriction target color is attached to the entire printing image IM satisfies a predetermined area standard, and the area ratio is predetermined. If the area standard is not satisfied, it is determined that the printing image IM does not satisfy the predetermined standard. As a result, it is possible to determine whether or not the printing image IM satisfies a predetermined criterion based on the color of the printing image IM and the area of the target region IMa to which the color is added. Thereby, for example, when the regulated color such as a color prohibited to be used by the landscape regulations and the area ratio where the regulated color is used are regulated, whether or not the printing image satisfies the regulation. It can be easily determined.

  Further, in the printing image determination system SYS according to the present embodiment, when the control device 10 determines that the printing image IM does not satisfy the predetermined standard, the control region 10 sets the target region IMa to which the restriction target color is added to the other region. The area is highlighted on the display device. Thereby, it is possible to easily grasp the target area IMa determined as not satisfying the predetermined standard in the printing image IM.

  In the printing image determination system SYS according to the present embodiment, when the control device 10 determines that the printing image IM does not satisfy a predetermined standard, the control device 10 applies to the target region IMa to which the restriction target color is attached. A candidate for a color different from the color to be regulated is displayed on the display device. Thus, the user can easily change the color or the like of the target area IMa that is determined to have the restriction target color in the printing image IM.

  Further, when the control device 10 determines that the printing image IM does not satisfy the predetermined standard, the user manually selects a color candidate different from the restriction target color for the target region IMa to which the restriction target color is attached. Can be selected.

  FIG. 8 is a diagram illustrating an example of a display screen when the user selects a color candidate. As illustrated in FIG. 8, the control device 11 displays the selection window 70 on the display device 30 after performing the determination. The selection window 70 includes a first color information adjustment unit 71, a second color information adjustment unit 72, a color display unit 73, a determination result display unit 74, an automatic conversion button 75, a recalculation button 76, and a decision button. 77 and a cancel button 78.

  The first color information adjustment unit 71 and the second color information adjustment unit 72 display information about the color of the printing image IM (hereinafter referred to as image color) based on different color systems, and are candidate colors. Information (hereinafter referred to as candidate colors) can be adjusted.

  The first color information adjustment unit 71 displays image colors based on, for example, the CMYK color system, and can adjust candidate color information.

The second color information adjustment unit 72 includes a pre-change information display unit 72a that displays image color information and a post-change information display unit 72b that displays candidate color information. The color information displayed on the pre-change information display portion 72a is a fixed value. On the other hand, the color information displayed on the post-change information display part 72b can be changed by the user. The post-change information display portion 72b is provided with a color information change button 72c. By operating the user to press the color information change button 72c, the color information options are displayed based on the Munsell color system. The user can set candidate colors by selecting color information from the displayed options. Color information of the set candidate colors is displayed on the post-change display unit 72b.

  The color display unit 73 includes a pre-change color display unit 73a that displays image colors and a post-change color display unit 73b that displays candidate colors. The user can directly compare the image color and the candidate color by viewing the image color and the candidate color displayed on the pre-change color display unit 73a and the post-change color display unit 73b.

  The control device 10 determines whether or not the predetermined standard is satisfied when the candidate color set by the user is set by the first color information adjustment unit 71 or the second color information adjustment unit 72. The determination result display unit 74 displays the determination result of the control device 10. For example, when it is determined that a predetermined criterion is satisfied, “◯” is displayed on the determination result display unit 74. If it is determined that the predetermined standard is not satisfied, “x” is displayed on the determination result display unit 74. The control device 10 performs color display processing so that the operation of the first color information adjustment unit 71 or the second color information adjustment unit 72 by the user is immediately reflected in the display of the color display unit 73 and the determination result display unit 74. The determination process and the determination result display process may be performed in real time.

  The automatic conversion button 75 is a button for automatically selecting a candidate color by the control device 10 and reflecting the selection result in the selection window 70. The recalculation button 76 is a button for returning the selection result selected by the user to the initial state. The decision button 77 is a button for setting a candidate color selected by the user or a candidate color selected by the control device 10 using the automatic conversion button 75. The cancel button 78 is a button for canceling the selection result and closing the selection window 70.

  In this way, by allowing the user to manually select a color candidate that is different from the restriction target color, the user can easily and flexibly change the color.
