[Solution] A color recognition index calculation unit 14 calculates a color recognition index, which is at least one of the contrast ratio and color difference as seen by a person with normal color vision, and a color recognition index as seen by a person with color weakness, for two uniform colors selected from the uniform colors registered in a uniform database 10. A determination unit 17 compares the color recognition indexes for people with normal color vision and those for people with color weakness calculated by the color recognition index calculation unit 14 with reference values, and determines the relationship in magnitude between the color recognition indexes for people with normal color vision and the reference values, and between the color recognition indexes for people with color weakness and the reference values. A display control unit 18 displays on a display unit 20 whether the two uniforms are suitable for people with normal color vision and whether the two uniforms are suitable for people with color weakness, according to the determination result by the determination unit 17.

Description

[Technical Field]

[0001] The present invention relates to a uniform combination feasibility determination device, a uniform combination feasibility determination method, and a uniform combination feasibility determination program. [Background technology]

[0002] Various sports such as soccer are broadcast on television or via the Internet, allowing viewers from all over the world to enjoy these sports. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2005-185588 Summary of the Invention [Problem to be solved by the invention]

[0004] In live broadcasts of sports such as soccer, rugby, American football, and basketball, in which players from two teams compete without being distinguished from each other, if the uniform colors of the two teams are similar, it becomes difficult to distinguish between the players of the two teams. Therefore, the two teams generally wear uniforms of different colors. However, even if people with normal color vision can distinguish the colors of the uniforms of the two teams, people with color blindness (color vision deficiency) may not be able to distinguish the colors of the uniforms of the two teams.

[0005] In some sports, two different uniforms are worn by the same team. For example, in soccer, the field players and goalkeepers wear different uniforms. While people with normal color vision can distinguish between the colors of two uniforms worn by the same team, people with color blindness may not be able to distinguish between the colors of the two uniforms.

[0006] It is said that the proportion of people with color blindness is roughly 1 in 20 men and 1 in 500 women in Asia, and 1 in 11-12 men and 1 in 200 women in Europe. There is a need for a uniform combination determination device, a uniform combination determination method, and a uniform combination determination program that can determine whether the colors of two uniforms can be combined by determining whether a person with normal color vision and a person with color blindness can distinguish between them. Patent Document 1 describes a system that warns people with color blindness about color combinations that are easily confused, but it is not possible to determine whether the two uniforms can be combined. [Means for solving the problem]

[0007] A first aspect of one or more embodiments provides a uniform combination feasibility determination device comprising: a uniform database that registers a plurality of uniform colors; a color recognition index calculation unit that calculates a color recognition index, which is at least one of the contrast ratio and color difference when viewed by a person with normal color vision, and the color recognition index when viewed by a person with color weakness, for two uniform colors selected from the colors registered in the uniform database; a determination unit that compares the color recognition index of the person with normal color vision and the color recognition index of the person with color weakness calculated by the color recognition index calculation unit with a reference value, and determines the relationship in magnitude between the color recognition index of the person with normal color vision and the reference value, and the color recognition index of the person with color weakness and the reference value; and a display control unit that displays on a display unit the feasibility of combining the two uniforms for the person with normal color vision and the feasibility of combining the two uniforms for the person with color weakness according to the determination result by the determination unit.

[0008] A second aspect of one or more embodiments provides a uniform combination feasibility determination method that calculates a color recognition index, which is at least one of the contrast ratio and color difference when viewed by a person with normal color vision, and the color recognition index when viewed by a person with color weakness, for two uniform colors selected from a plurality of uniform colors registered in a uniform database, compares the color recognition index of the person with normal color vision and the color recognition index of the person with color weakness with a reference value, determines the magnitude relationship between the color recognition index of the person with normal color vision and the reference value, and the magnitude relationship between the color recognition index of the person with color weakness and the reference value, and displays on a display unit the feasibility of combining the two uniforms for the person with normal color vision and the feasibility of combining the two uniforms for the person with color weakness according to the determination result of the magnitude relationship.

[0009] A third aspect of one or more embodiments provides a uniform combination feasibility determination program that causes a computer to perform the following steps: calculate a color recognition index, which is at least one of the contrast ratio and color difference when viewed by a person with normal color vision, for two uniform colors selected from a plurality of uniform colors registered in a uniform database, and the color recognition index when viewed by a person with color weakness; compare the color recognition index of the person with normal color vision and the color recognition index of the person with color weakness with a reference value to determine the magnitude relationship between the color recognition index of the person with normal color vision and the reference value, and the magnitude relationship between the color recognition index of the person with color weakness and the reference value; and display on a display unit the feasibility of combining the two uniforms for the person with normal color vision and the feasibility of combining the two uniforms for the person with color weakness according to the determination result of the magnitude relationship.

DETAILED DESCRIPTION OF THE INVENTION

[0012] Hereinafter, a uniform combination feasibility determination device, a uniform combination feasibility determination method, and a uniform combination feasibility determination program according to one or more embodiments will be described with reference to the accompanying drawings.

[0013] 1 shows a uniform combination acceptability determination device 100 according to one or more embodiments. The uniform combination acceptability determination device 100 includes a uniform database (hereinafter referred to as "uniform DB") 10, an operation unit 11, an operation determination unit 12, a selected uniform data storage unit 13, a color recognition index calculation unit 14, a color recognition index adjustment unit 15, a reference value setting unit 16, a determination unit 17, a display control unit 18, a memory unit 19, a display unit 20, and a printing machine 21. At least a portion of the uniform combination acceptability determination device 100 can be configured by a computer.

[0014] The uniform DB 10 can be configured with a rewritable memory. The operation unit 11 can be configured with a mouse and keyboard, or with a touch panel integrated with the display unit 20. The operation determination unit 12 can be configured with a central processing unit (CPU) provided in a computer. The selected uniform data storage unit 13 can be configured with a memory for temporary storage. The color recognition index calculation unit 14, the color recognition index adjustment unit 15, the determination unit 17, and the display control unit 18 can be configured with a CPU. The reference value setting unit 16 can be configured with a non-volatile memory.

[0015] The storage unit 19 can be configured with any non-volatile memory, and may be a removable memory such as a memory card. The display unit 20 is, for example, a liquid crystal panel. The display unit 20 may be configured to be external to the uniform combination feasibility determination device 100. The printing machine 21 may also be configured to be external to the uniform combination feasibility determination device 100. The storage unit 19 and the printing machine 21 are not essential components.

[0016] Using soccer as an example, the type of uniform data stored in the uniform DB 10 will be described. The uniform DB 10 stores the colors of the uniforms worn by each of a plurality of teams. The uniform DB 10 stores the colors of the uniforms worn by each of the teams. * a * b * Color space L * value, a * value, b * The value is registered.

[0017] As conceptually shown in Figure 2, the uniform DB 10 has registered therein the colors of the uniforms worn by team A, namely, the colors of the uniforms AFP1 to AFP3 worn by the field players and the colors of the uniforms AGK1 to AGK3 worn by the goalkeepers. The different hatching of each uniform shown in Figure 2 indicates different colors. The uniform DB 10 has registered therein the colors of the uniforms BFP1 to BFP3 worn by the field players and the colors of the uniforms BGK1 to BGK3 worn by the goalkeepers, as the colors of the uniforms worn by team B.

[0018] Team A's uniform AFP1 is the uniform that Team A normally wears when playing against other teams as the home team, and Team A's uniform AFP2 is the uniform that Team A normally wears when playing against other teams as the away team. Team B's uniform BFP1 is the uniform that Team B normally wears when playing against other teams as the home team, and Team B's uniform BFP2 is the uniform that Team B normally wears when playing against other teams as the away team. Team A's uniform AFP3 and Team B's uniform BFP3 are so-called third uniforms.

[0019] The uniform DB 10 stores the colors of the uniforms worn by field players and goalkeepers of other teams (not shown). The uniform DB 10 also stores the color of the uniform RF1 as the color of the uniform worn by the referees.

[0020] The colors of each uniform registered in the uniform DB10 are defined as follows. FIG. 3A shows uniform AFP1 as an example of a uniform registered in the uniform DB10. Uniform AFP1 has the team name "TeamA" printed on the chest. A sponsor's name may be printed on the chest of a uniform instead of the team name. Uniform AFP1 is a single-color uniform. For example, the color of a rectangular area 31 enclosed by a dashed line below the team name or sponsor's name printed on the chest is defined as the color of uniform AFP1. In this way, if a single color exists within a predetermined area, such as area 31 on the front of the uniform, that single color can be registered in the uniform DB10 as the uniform color.

[0021] FIG. 3B shows a uniform AFP1' in which two colors are mixed, instead of the single-color uniform AFP1. When multiple colors exist within a predetermined area with a predetermined surface area, such as the area 31 on the front of the uniform, the color obtained by averaging the multiple colors within the predetermined area can be registered in the uniform DB10 as the color of the uniform. Specifically, the average RGB value, which is the average value of the R (red), G (green), and B (blue) values ​​of the three primary colors of all pixels included in the area 31 in the image data of the uniform AFP1', is calculated. The average RGB value is calculated as L * value, a * value, b * The color is converted into a value and registered in the uniform DB10 as the color of uniform AFP1'.

[0022] In Figure 3B, the color within range 31 of uniform AFP1' is different from the color within range 31 of uniform AFP1 shown in Figure 3A due to the averaging of two colors within range 31. Even if the uniform contains three or more colors, the color obtained by averaging the three or more colors within range 31 can be registered in uniform DB10 as the color of the uniform.

[0023] 4 shows a schematic configuration of a computer 200 that executes a uniform combination approval determination program according to one or more embodiments. The computer 200 includes a central processing unit (CPU) 201, a non-transitory storage medium 202, an operation unit 203, a storage unit 204, and a display unit 205. The non-transitory storage medium 202 stores a uniform combination approval determination program. When the CPU 201 executes the uniform combination approval determination program, the computer 200 has a configuration equivalent to that of the uniform combination approval determination device 100.

[0024] The operation unit 203 has the same configuration as the operation unit 11 in FIG. 1. The memory unit 204 has the same configuration as the memory unit 19 in FIG. 1. The display unit 205 has the same configuration as the display unit 20 in FIG. 1. The display unit 205 may be configured to be external to the computer 200. A printing machine (not shown) may be external to the computer 200. The uniform combination feasibility determination program has a uniform DB similar to the uniform DB 10.

[0025] 5A to 5D, a uniform combination approval determination method according to one or more embodiments will be described, which is executed by the uniform combination approval determination device 100. The flowcharts shown in Figures 5A to 5D also show the processing that the uniform combination approval determination program according to one or more embodiments causes the computer 200 (CPU 201) to execute.

[0026] The flowcharts shown in Figures 5A to 5D will be described as a method executed by the uniform combination acceptability determination device 100. In the processing executed by the uniform combination acceptability determination program on the computer 200, the operation unit 11 is replaced with an operation unit 203, and the operation determination unit 12, selected uniform data storage unit 13, color recognition index calculation unit 14, color recognition index adjustment unit 15, determination unit 17, and display control unit 18 are replaced with a CPU 201. The storage unit 19 is replaced with a storage unit 204, and the display unit 20 is replaced with a display unit 205. A printing machine not shown in Figure 4 will be referred to as a printing machine 21.

[0027] In FIG. 5A, when processing starts, the operation determination unit 12 determines in step S1 whether or not a match mode has been selected. Match mode is a mode in which a person with normal color vision and a person with color blindness can distinguish between the uniforms worn by two competing teams, and confirms whether the two uniforms can be combined. If match mode is selected (YES), the display control unit 18 displays an initial image of the match checklist 40 on the display unit 20 in step S2. If match mode is not selected (NO), the processing proceeds to step S20 in FIG. 5C. When the uniform combination determination program is launched, a default state may be set so that the match checklist 40 is selected.

[0028] FIG. 6 shows an example of an initial image of the match confirmation table 40. The confirmation table 40 has, as menus displayed on the menu bar, a file read button 401 labeled "File" and a reference value setting button 402 labeled "Reference Value Settings." The confirmation table 40 has a home team selection button 403 for selecting the home team, an away team selection button 404 for selecting the away team, and a mode selection button 405. The mode selection button 405 includes a button labeled "Match" for selecting the match confirmation table 40, and a button labeled "Design" for selecting the design confirmation table 50. The design confirmation table 50 will be described later.

[0029] The confirmation table 40 has a confirmation button 406 for confirming the home team selected with the home team selection button 403, the away team selected with the away team selection button 404, and a recommended uniform button 407 for displaying recommended uniforms.

[0030] The confirmation table 40 has a home team row 411 indicating a combination of one uniform worn by the home team and multiple uniforms worn by either the away team or the home team, and an away team row 412 indicating a combination of one uniform worn by the away team and multiple uniforms worn by either the home team or the away team. The confirmation table 40 has a general color vision column 420, a P color vision column 421, and a D color vision column 422 corresponding to normal color vision, protanopia (deuteranopia) color deficiency, and deuteranopia (deuteranopia) color deficiency, respectively. The confirmation table 40 may have either the P color vision column 421 or the D color vision column 422. It is preferable that the confirmation table 40 have both the P color vision column 421 and the D color vision column 422.

[0031] The general color vision column 420, P-type color vision column 421, and D-type color vision column 422 each include a contrast ratio determination column 420c, 421c, and 422c for indicating the result of a contrast ratio determination as one of the color recognition indices, and a color difference determination column 420e, 421e, and 422e for indicating the result of a color difference determination as another of the color recognition indices. Here, the color difference is ΔE00, which is a numerical value of the color difference calculated based on the CIEDE2000 color difference formula. Either the contrast ratio or the color difference may be used as the color recognition indices. It is preferable to use both the contrast ratio and the color difference as the color recognition indices.

[0032] Each section determined by a combination of the home team row 411, the away team row 412, the contrast ratio judgment columns 420c, 421c, and 422c, and the color difference judgment columns 420e, 421e, and 422e is a combination feasibility display column that shows whether two uniforms can be combined. A combination of two uniforms that is feasible means that the colors of the two uniforms can be distinguished, and for example, the two competing teams can be distinguished. A combination of two uniforms that is not feasible means that the colors of the two uniforms are difficult to distinguish, and for example, the two competing teams can be difficult to distinguish.

[0033] The confirmation sheet 40 has color display columns 430, 431, and 432 adjacent to the D-type color vision column 422, which show the colors that a person with normal color vision, a person with P-type color vision, and a person with D-type color vision will recognize when looking at each uniform. The confirmation sheet 40 has a save button 441 for storing the confirmation sheet 40 in the memory unit 19, and a print button 442 for printing the confirmation sheet 40 on the printer 21. The confirmation sheet 40 has an exit button 450 marked with an "x" in the upper right corner.

[0034] Returning to FIG. 5A, the operation determination unit 12 determines in step S3 whether or not the home team has been selected. If the home team has been selected (YES), the operation determination unit 12 determines in step S4 whether or not the away team has been selected. If the away team has been selected (YES), the operation determination unit 12 determines in step S5 whether or not the decision button 406 has been operated. An operation on the confirmation table 40 means, for example, touching the display unit 20 with a finger or the like if the operation unit 11 is a touch panel, or clicking with the mouse if the operation unit 11 is a mouse.

[0035] If the enter button 406 is operated in step S5 (YES), the operation determination unit 12 reads the uniform data of the selected team in step S8. The selected uniform data storage unit 13 stores the read uniform data. Taking team A shown in FIG. 2 as an example, the uniform data includes a uniform ID unique to each of the uniforms AFP1 to AFP3 and AGK1 to AGK3, and the color of each uniform.

[0036] If the home team is not selected in step S3 (NO), if the away team is not selected in step S4 (NO), or if the enter button 406 is not operated in step S5, the operation determination unit 12 determines in step S6 whether the design mode has been selected by operating the button for selecting the design confirmation table 50 among the mode selection buttons 405. If the design mode has been selected (YES), the process proceeds to step S21 in FIG. 5C. The design mode is a mode for determining whether a person with normal color vision and a person with color blindness can distinguish between two uniforms worn by the same team, and confirming whether the two uniforms can be combined. The design mode is a mode suitable for use in determining the colors of multiple uniforms when designing multiple uniforms to be worn by one's team.

[0037] If the design mode is not selected (NO), the operation determination unit 12 determines in step S7 whether or not an instruction has been given to end the display of the checklist 40. If the end button 450 is operated, the display control unit 18 ends the display of the checklist 40. If an instruction to end the display of the checklist 40 has not been given (NO), the process returns to step S3.

[0038] Following step S8, the color recognition index calculation unit 14 calculates a color recognition index between the colors of the uniforms in step S9. In detail, the color recognition index calculation unit 14 calculates a color recognition index, which is at least one of the contrast ratio and color difference, when a person with normal color vision views the two uniform colors, and a color recognition index when a person with color-deficient vision (a person with P-type color vision and a person with D-type color vision) views the two uniform colors.

[0039] The color recognition index calculation unit 14 can calculate the contrast ratio between the colors of the two uniforms and the value of ΔE00 as follows.

[0040] The color recognition index calculation unit 14 calculates the L of each uniform registered in the uniform DB 10. * value, a * value, b * The color perception index calculation unit 14 converts the RGB values ​​into X, Y, and Z tristimulus values ​​in the XYZ color system, and then converts the X, Y, and Z tristimulus values ​​into L, M, and S cone stimulus values ​​in the LMS color space for a normal color vision person, a P-type color vision person, and a D-type color vision person. The color perception index calculation unit 14 converts the L, M, and S cone stimulus values ​​back into X, Y, and Z tristimulus values ​​and then back into RGB values, thereby calculating the contrast ratio when a normal color vision person, a P-type color vision person, and a D-type color vision person each view the colors of the two uniforms.

[0041] The color recognition index calculation unit 14 calculates the L of each uniform registered in the uniform DB 10. * value, a * value, b * The color recognition index calculation unit 14 converts the L, M, and S cone stimulus values ​​back into the X, Y, and Z tristimulus values, and then converts the X, Y, and Z tristimulus values ​​into the L, M, and S cone stimulus values ​​in the LMS color space for a normal color vision person, a P-type color vision person, and a D-type color vision person. * value, a * value, b * The values ​​are converted into ΔE00 values ​​when a person with normal color vision, a person with P-type color vision, and a person with D-type color vision each view the colors of the two uniforms, and the values ​​are calculated.

[0042] In step S10, the determination unit 17 determines whether each uniform combination is acceptable, as will be described later. In step S11, the display control unit 18 displays whether the combination is acceptable in each combination acceptable / unacceptable display column of the checklist 40. Thereafter, the process proceeds to step S12 in FIG. 5B.

[0043] Take the example where team A is selected as the home team and team B is selected as the away team. Team A is the first team and team B is the second team. As shown in FIG. 7, the home team row 411 displays a uniform AFP1 for the field players of team A. The home team row 411 also displays a uniform BFP2 for the field players of team B, a uniform AGK1 for the goalkeepers of team A, a uniform BGK2 for the goalkeepers of team B, and a uniform RF1 for the referees, which are to be combined with the uniform AFP1.

[0044] The away team row 412 displays the uniform BFP2 for the field players of team B. The away team row 412 also displays the uniform AGK1 for the goalkeepers of team A, the uniform BGK2 for the goalkeepers of team B, and the uniform RF1 for the referees, which are to be combined with the uniform BFP2. As shown in FIG. 7 , the display control unit 18 may display a combination selected from the uniforms of team A and team B registered in the uniform DB 10 on the checklist 40.

[0045] The reference value setting unit 16 (uniform combination possibility determination program) sets, as an example, reference values ​​as shown in Fig. 8. In Fig. 8, FP indicates a uniform for any field player, GK indicates a uniform for any goalkeeper, and RF indicates a uniform for any referee. C, P, and D indicate normal color vision, P-type color vision, and D-type color vision, respectively.

[0046] FP-FP indicates a combination of a uniform for the home team's field players and a uniform for the away team's field players. FP-GK indicates a combination of the home team's FP and the home team's GK, a combination of the home team's FP and the away team's GK, a combination of the away team's FP and the home team's GK, or a combination of the away team's FP and the away team's GK. FP-RF indicates a combination of the home team's FP and RF, or a combination of the away team's FP and RF. GK-RF indicates a combination of the home team's GK and RF, or a combination of the away team's GK and RF.

[0047] As shown in Figure 8, the reference values ​​for normal color vision, P-type color vision, and D-type color vision are set as follows: a contrast ratio of 3.0 and a ΔE00 value of 14.0 for FP-FP, and a contrast ratio of 2.5 and a ΔE00 value of 12.0 for FP-GK, FP-RF, and GK-RF.

[0048] Figure 8 shows that a contrast ratio of at least 3.0 and a ΔE00 value of at least 14.0 are required between the color of the home team's field player uniforms and the color of the away team's field player uniforms. Figure 8 also shows that a contrast ratio of at least 2.5 and a ΔE00 value of at least 12.0 are required between the color of the field player uniforms and the color of the goalkeeper uniforms, between the color of the field player uniforms and the uniforms of the referees, and between the color of the goalkeeper uniforms and the uniforms of the referees.

[0049] The contrast ratio and ΔE00 value for FP-FP are set to be larger than the contrast ratio and ΔE00 values ​​for FP-GK, FP-RF, and GK-RF because there is a greater need to distinguish between the uniforms for the home team's field players and the uniforms for the away team's field players. The same reference value may be used for all of FP-FP, FP-GK, FP-RF, and GK-RF. Different reference values ​​may be set for FP-GK, FP-RF, and GK-RF. The user can set any reference value by operating the reference value setting button 402.

[0050] The determination unit 17 compares the color recognition index for people with normal color vision and the color recognition index for people with color weakness with the reference values ​​set as shown in Fig. 8 to determine the magnitude relationship between the color recognition index for people with normal color vision and the reference values ​​and the color recognition index for people with color weakness. As shown in Fig. 7, the display control unit 18 displays whether the combination of two uniforms is possible for people with normal color vision and whether the combination of two uniforms is possible for people with color weakness in each combination possibility display column of the checklist 40 according to the determination result.

[0051] 7 shows an example in which the determination unit 17 determines whether or not a combination of two uniforms is acceptable based on three levels: "acceptable," "acceptable depending on conditions," and "unacceptable." For combinations of field player uniforms, if the contrast ratio is equal to or greater than the reference value of 3.0, the combination is deemed "acceptable," if it is 2.5 to 2.9, the combination is deemed "acceptable depending on conditions," and if it is 2.4 or less, the combination is deemed "unacceptable." For combinations of field player uniforms and goalkeeper uniforms, combinations of field player uniforms and referee uniforms, and combinations of goalkeeper uniforms and referee uniforms, the combination is deemed "acceptable" if the contrast ratio is equal to or greater than the reference value of 2.5, if it is 2.1 to 2.4, the combination is deemed "acceptable," and if it is 2.0 or less, the combination is deemed "unacceptable."

[0052] Similarly, for the ΔE00 value, the ranges of "Acceptable," "Acceptable under certain conditions," and "Not acceptable" are set based on the reference value of ΔE00 of 14.0 or 12.0.

[0053] In Fig. 7, the display control unit 18 displays "OK" if the combination of two uniforms is possible, "Conditional" if possible depending on the conditions, and "NG" if possible. Note that Fig. 7 shows an example in which there is no value for ΔE00 that corresponds to possible depending on the conditions, and there are only values ​​that correspond to possible and impossible. The display control unit 18 may display the corresponding symbols instead of "OK", "Conditional", and "NG".

[0054] The determination unit 17 may determine whether the combination of two uniforms is acceptable in two stages: "acceptable" and "unacceptable." In this case, the determination unit 17 determines that the combination of two uniforms is acceptable if the color recognition index is equal to or greater than a reference value, and determines that the combination of two uniforms is unacceptable if the color recognition index is smaller than the reference value.

[0055] The sections directly below the sections marked C, P, and D in color display columns 430, 431, and 432 display the colors perceived by a person with normal color vision, a person with P-type color vision, and a person with D-type color vision when they view uniform AFP1. The color display columns 430, 431, and 432 corresponding to the rows of uniforms BFP2, AGK1, BGK2, and RF1 in the home team row 411 display the colors perceived by a person with normal color vision, a person with P-type color vision, and a person with D-type color vision when they view uniforms BFP2, AGK1, BGK2, and RF1, respectively. The color display columns 430, 431, and 432 corresponding to the rows of uniforms AGK1, BGK2, and RF1 in the away team row 412 display the colors perceived by a person with normal color vision, a person with P-type color vision, and a person with D-type color vision when they view uniforms AGK1, BGK2, and RF1, respectively.

[0056] In the sections marked AFP1, BFP2, AGK1, BGK2, RF1 in the home team row 411 and BFP2, AGK1, BGK2, RF1 in the away team row 412, the colors that a person with normal color vision would recognize when looking at each uniform may be displayed, similar to the color display column 430.

[0057] When any of the combination feasibility display fields displaying, for example, "OK," "Conditional," or "NG" is operated, the determination unit 17 displays the value of the color recognition index calculated by the color recognition index calculation unit 14 in each combination feasibility display field, as shown in Fig. 9. If the value of the color recognition index is displayed in the check list 40, the user can directly recognize the contrast ratio and the value of ΔE00.

[0058] As described above, the user can determine whether or not two uniforms can be combined using the checklist 40 displayed on the display unit 20 as shown in FIG. 7. It is up to the operator whether two uniforms can be combined if both the contrast ratio and the ΔE00 value are acceptable, or whether two uniforms can be combined if at least one of the contrast ratio and the ΔE00 value is acceptable. It may be decided that two uniforms can be combined if both the contrast ratio and the ΔE00 value are acceptable for all people with normal color vision, P-type color vision, and D-type color vision. It may be decided that two uniforms can be combined if both the contrast ratio and the ΔE00 value are acceptable for any of people with normal color vision, P-type color vision, and D-type color vision.

[0059] The conditions under which two uniforms can be combined can be decided by the league to which each team belongs, and the league to which each team belongs can decide how strictly the colors of the two uniforms can differ during a match and set a standard value.

[0060] In FIG. 5B, the operation determination unit 12 determines in step S12 whether or not the recommended uniform button 407 has been operated. If the recommended uniform button 407 has been operated (YES), the process proceeds to step S14. If the recommended uniform button 407 has not been operated (NO), the operation determination unit 12 determines in step S13 whether or not the uniform has been changed manually. If the uniform has been changed manually (YES), the process proceeds to step S14. If the uniform has not been changed manually (NO), the process proceeds to step S15.

[0061] In the example shown in Figure 7, the combination of the uniform AFP1 for field players of Team A and the uniform BFP2 for field players of Team B is often not allowed. Assume that all combinations of the uniform AFP1 for field players of Team A and the uniform BFP3 for field players of Team B, which is not shown in Figure 7, are allowed.

[0062] 10, when the recommended uniform button 407 is operated, the display control unit 18 displays the uniform BFP3 as the uniform for the field players of team B to be combined with the uniform AFP1 for the field players of team A in step S14. The combination of the uniform AFP1 and the uniform BFP3 is determined to be acceptable for all people with normal color vision, P-type color vision, and D-type color vision, and the combination of the two uniforms is displayed as OK.

[0063] The uniform AFP1 in the home team row 411 may be manually changed to the uniform AFP2 or AFP3, or the uniform combined with the uniform AFP1 may be changed to another uniform. The uniform BFP2 in the away team row 412 may be manually changed to the uniform BFP1 or BFP3, or the uniform combined with the uniform BFP2 may be changed to another uniform. If the uniform displayed in the confirmation list 40 is manually changed, the display control unit 18 displays the confirmation list 40 updated to include the changed uniform and whether it can be combined in step S14.

[0064] In step S15, the operation determination unit 12 determines whether or not the save button 441 has been operated to save the confirmation table 40. If the operation to save the confirmation table 40 has been operated (YES), the storage unit 19 saves the confirmation table 40 in step S16, and the process proceeds to step S19. If the operation to save the confirmation table 40 has not been operated (NO), the operation determination unit 12 determines in step S17 whether or not the print button 442 has been operated to print the confirmation table 40. If the operation to print the confirmation table 40 has been operated (YES), the printer 21 prints the confirmation table 40 in step S18, and the process proceeds to step S19. If the operation to print the confirmation table 40 has not been operated (NO), the process proceeds to step S19.

[0065] In step S19, the operation determination unit 12 determines whether or not the design mode has been selected. If the design mode has been selected (YES), the process proceeds to step S21 in FIG. 5C. If the design mode has not been selected (NO), the operation determination unit 12 determines in step S20 whether or not an instruction to end the display of the checklist 40 has been given. If an instruction to end the display of the checklist 40 has not been given (NO), the process returns to step S3. If an instruction to end the display of the checklist 40 has been given (YES), the display control unit 18 ends the display of the checklist 40. In this way, the confirmation of the acceptability of each uniform combination using the checklist 40 for the battle mode is completed.

[0066] The display control unit 18 can read out the check list 40 stored in the storage unit 19 and display it again on the display unit 20 by operating the operation unit 11.

[0067] 5C, in step S21, the display control unit 18 displays an initial image of the design checklist 50 on the display unit 20. The initial image of the design checklist 50 is not shown. The initial image of the design checklist 50 is in a state in which no team has been selected in the checklist 50 shown in FIG. 11 and the availability of each uniform combination is not displayed.

[0068] As shown in FIG. 11 , the check table 50 has a file read button 501, a reference value setting button 502, a team selection button 503, a mode selection button 505, a save button 541, a print button 542, and an end button 550. The check table 50 has first to third uniform combination rows 511 to 513 indicating combinations of three field player uniforms and three goalkeeper uniforms worn by the team selected with the team selection button 503, as well as a general color vision column 520, a P color vision column 521, and a D color vision column 522. The check table 50 may have either the P color vision column 521 or the D color vision column 522. It is preferable that the check table 50 have both the P color vision column 521 and the D color vision column 522.

[0069] The general color vision column 520, P-type color vision column 521, and D-type color vision column 522 each include a contrast ratio judgment column 520c, 521c, and 522c, and a color difference judgment column 520e, 521e, and 522e. Here, the color difference is also defined as ΔE00. Either the contrast ratio or the color difference may be used as the color recognition index. It is preferable to use both the contrast ratio and the color difference as the color recognition index.

[0070] The check list 50 has recommended value display buttons 551 to 553 labeled "recommended value" corresponding to the first to third uniform combination rows 511 to 513, respectively.

[0071] Each section determined by the combination of the first to third uniform combination rows 511 to 513, the contrast ratio judgment columns 520c, 521c, and 522c, and the color difference judgment columns 520e, 521e, and 522e is a combination possibility display column that indicates whether two uniforms worn on the same team can be combined. Two uniforms worn on the same team that are possible to combine means that the colors of the two uniforms can be distinguished and players with different roles on the same team (field players and goalkeepers) can be distinguished. Two uniforms worn on the same team that are not possible to combine means that the colors of the two uniforms are difficult to distinguish and players with different roles on the same team are difficult to distinguish.

[0072] Returning to FIG. 5C, the operation determination unit 12 determines in step S22 whether or not a team has been selected. If a team has not been selected (NO), the operation determination unit 12 determines in step S23 whether or not a battle mode has been selected. If the battle mode has been selected (YES), the process proceeds to step S2 in FIG. 5A. If the battle mode has not been selected (NO), the operation determination unit 12 determines in step S24 whether or not an instruction to end the display of the check list 50 has been given. If an instruction to end the display of the check list 50 has been given (YES), the display control unit 18 ends the display of the check list 50. If an instruction to end the display of the check list 50 has not been given (NO), the process returns to step S22.

[0073] If a team is selected in step S22 (YES), the operation determination unit 12 reads the uniform data of the selected team in step S25. The selected uniform data storage unit 13 stores the read uniform data. Taking team A shown in Figure 2 as an example, the uniform data includes a uniform ID unique to each of the uniforms AFP1 to AFP3 and AGK1 to AGK3, and the color of each uniform.

[0074] In step S26, the color recognition index calculation unit 14 calculates a color recognition index between the colors of the uniforms. In detail, the color recognition index calculation unit 14 calculates a color recognition index that is at least one of the contrast ratio and color difference when a person with normal color vision sees the colors of the two uniforms, and a color recognition index when a person with color-deficient vision (a person with P-type color vision and a person with D-type color vision) sees the colors of the two uniforms. In step S27, the determination unit 17 determines whether each combination of uniforms is possible, similar to the determination of whether a combination of two uniforms is possible in the battle mode. In step S28, the display control unit 18 displays whether the combination is possible in each combination possible display column of the checklist 50, as shown in FIG. 11.

[0075] 11, if the color recognition index is equal to or greater than the reference value, the combination of the two uniforms is determined to be acceptable and is displayed as "OK," whereas if the color recognition index is less than the reference value, the combination of the two uniforms is determined to be unacceptable and is displayed as "NG." As with the checklist 40, a "Conditional" option may be added if the combination is acceptable under certain conditions.

[0076] In FIG. 11, the colors that a person with normal color vision would recognize when looking at each uniform should be displayed in the sections marked AFP1 to AFP3 and AGK1 to AGK3 in the first to third uniform combination rows 511 to 513.

[0077] Returning to Fig. 5C, in step S29, the operation determination unit 12 determines whether or not an operation to display recommended color values ​​for any two uniform combinations has been performed. If an operation to display recommended values ​​has not been performed (NO), the process proceeds to step S33 in Fig. 5D. If an operation to display recommended values ​​has been performed (YES), the color recognition index adjustment unit 15 calculates, in step S30, a lightness increase / decrease value that makes the combination acceptable.

[0078] 12A and 12B conceptually show the procedure for calculating the brightness increase / decrease value executed internally by color recognition index adjustment unit 15. As shown in FIG. 11, assume that the combination of field player uniform AFP1 and goalkeeper uniform AGK1 is often unacceptable, and a command is issued to display recommended color values ​​for the combination of uniform AFP1 and uniform AGK1 using recommended value display button 551. Of uniform AFP1 and uniform AGK, color recognition index adjustment unit 15 leaves the color of uniform AFP1 unchanged and sets it as a reference value, and changes the color of uniform AGK.

[0079] As shown in Figure 12A, when a person with normal color vision viewed the uniform AFP1, L * The value is 39, which is the L value when a person with normal color vision sees the AGK uniform. * The value is 53. * The value is the brightness. Uniform AGK L * Increasing the value by 5, 10, 15, 20, 25, 30 will result in the changed L * The values ​​are 58, 63, 68, 73, 78, and 83. Uniform AGK L * Decreasing the value by 5, 10, 15, 20, 25, 30 will result in the changed L * The values ​​are 48, 43, 38, 33, 28, and 23.

[0080] AGK uniform L * When the value is 53, the RGB values ​​are 82, 140, and 85, and the contrast ratio is 1.7. * The RGB values ​​and contrast ratios are shown for values ​​58 to 83 and 48 to 23. * The contrast ratio is 2.0 to 4.4, corresponding to values ​​of 58 to 83. * The contrast ratios are 1.4 to 1.7, corresponding to values ​​of 48 to 23.

[0081] As shown in Figure 12B, when a P-type color vision person looks at the uniform AFP1, * The value is 27, and the L value is 27 when a P-type color vision person sees the uniform AGK. * The value is 57. Uniform AGK L* Increasing the value by 5, 10, 15, 20, 25, 30 will result in the changed L * The values ​​are 62, 67, 72, 77, 82, and 87. Uniform AGK L * Decreasing the value by 5, 10, 15, 20, 25, 30 will result in the changed L * The values ​​are 52, 47, 42, 37, 32, and 27. * The contrast ratios are 3.4 to 7.3 and 2.4 to 1.0, corresponding to values ​​of 62 to 87 and 52 to 27. RGB values ​​are omitted.

[0082] As shown in Figure 12B, when a D-type color vision person looks at the uniform AFP1, * The value is 42, and the L value is 42 when a D-type color vision person sees the uniform AGK. * The value is 51. Uniform AGK L * Increasing the value by 5, 10, 15, 20, 25, 30 will result in the changed L * The values ​​are 56, 61, 66, 71, 76, and 81. Uniform AGK L * Decreasing the value by 5, 10, 15, 20, 25, 30 will result in the changed L * The values ​​are 46, 41, 36, 31, 26, and 21. * The contrast ratios are 1.8 to 3.7 and 1.2 to 2.1, corresponding to values ​​of 56 to 81 and 46 to 21. RGB values ​​are omitted.

[0083] Here, if the standard value of the contrast ratio is 3.0, the standard value of 3.0 or more is achieved for all people with normal color vision, P-type color vision, and D-type color vision, as shown in the bold solid line, in the L * This is when the value is increased by 25. The contrast ratios for normal color vision, P-type color vision, and D-type color vision are 3.8, 6.3, and 3.2, respectively. If the reference value for the contrast ratio is 2.5, as in Figure 8, then L * Just increase the value by 15.

[0084] As described above, it is assumed that the determination unit 17 determines that the combination of two uniforms is unacceptable for people with normal color vision or people with color weakness based on the magnitude relationship between the color recognition index of a person with normal color vision and the reference value and the color recognition index of a person with color weakness and the reference value. It is assumed that an instruction is given to display recommended color recognition index values ​​that make the combination of the two uniforms acceptable on the display unit 20. The color recognition index adjustment unit 15 adjusts the lightness of the color of one of the two uniforms so that the contrast ratio when a person with normal color vision and a person with color weakness view the colors of the two uniforms is equal to or greater than the reference value.

[0085] Returning to FIG. 5C, in step S31, the display control unit 18 displays the colors of the uniforms that can be combined on the display unit 20. In step S32, the operation determination unit 12 determines whether or not an operation to display recommended color values ​​for the other two uniform combinations has been performed. If an operation to display recommended color values ​​for the other two uniform combinations has not been performed (NO), the process proceeds to step S33. If an operation to display recommended color values ​​for the other two uniform combinations has been performed (YES), the color recognition index adjustment unit 15 similarly adjusts the brightness of the color of one of the two uniforms.

[0086] Let's assume that the brightness of the uniform colors is adjusted for the combinations of uniform AFP1 and uniform AGK1, uniform AFP1 and uniform AGK3, and uniform AFP2 and uniform AGK2, which are all combinations that are not permitted in the confirmation table 50 shown in Figure 11. Figure 13 shows an example of an adjusted color table that includes recommended values ​​for the color recognition index of uniforms that are permitted to be combined and are displayed on the display unit 20. In the adjusted color table shown in Figure 13, the results show the contrast ratio when a person with general color vision views the two uniforms after adjusting the brightness of the colors of uniforms AGK1, AGK3, and AGK2.

[0087] As shown in Fig. 13, the adjusted color table shows the RGB values ​​of uniform AFP1 and uniform AGK1 after brightness adjustment, uniform AFP1 and uniform AGK3 after brightness adjustment, and uniform AFP2 and uniform AGK2 after brightness adjustment. The adjusted color table shown in Fig. 13 also shows the ΔE00 values ​​when a person with P color vision and a person with D color vision views the two uniforms. The adjusted color table may be displayed on display unit 20 simultaneously with check table 50, or may be displayed on display unit 20 in place of check table 50.

[0088] By looking at the adjusted color chart, users can recognize the colors that are acceptable for combinations of two uniforms for people with normal color vision, P-type color vision, and D-type color vision. By setting the colors of the uniforms worn by their team to the colors shown in the adjusted color chart, users can avoid situations where they cannot distinguish between the uniforms for field players and the uniforms for goalkeepers on the same team.

[0089] 5D, the operation determination unit 12 determines in step S33 whether or not the operation to save the confirmation table 50 has been performed using the save button 541. If the operation to save the confirmation table 50 has been performed (YES), the storage unit 19 saves the confirmation table 50 in step S34, and the process proceeds to step S37. If the operation to save the confirmation table 50 has not been performed (NO), the operation determination unit 12 determines in step S35 whether or not the operation to print the confirmation table 50 has been performed using the print button 542. If the operation to print the confirmation table 50 has been performed (YES), the printer 21 prints the confirmation table 50 in step S36, and the process proceeds to step S37. If the operation to print the confirmation table 50 has not been performed (NO), the process proceeds to step S37.

[0090] In step S37, the operation determination unit 12 determines whether or not the battle mode has been selected. If the battle mode has been selected (YES), the process proceeds to step S2 in FIG. 5A. If the battle mode has not been selected (NO), the operation determination unit 12 determines in step S38 whether or not an instruction to end the display of the check list 50 has been given. If an instruction to end the display of the check list 50 has not been given (NO), the process returns to step S22 in FIG. 5C. If an instruction to end the display of the check list 50 has been given (YES), the display control unit 18 ends the display of the check list 50. In this way, the confirmation of the acceptability of each uniform combination using the check list 50 for design mode is completed.

[0091] By operating the operation unit 11, the display control unit 18 can read out the check table 50 stored in the memory unit 19 and display it again on the display unit 20. After reading out the check table 50 stored in the memory unit 19 and displaying it again on the display unit 20, the color recognition index adjustment unit 15 can also calculate the increase / decrease value of the lightness that makes the combination possible.

[0092] The present invention is not limited to one or more of the embodiments described above, and various modifications are possible without departing from the spirit of the present invention. The uniform combination feasibility determination program described above is configured to allow switching between battle mode and design mode. In this way, the uniform combination feasibility determination program can be used in both battle mode and design mode. The uniform combination feasibility determination program for battle mode and the uniform combination feasibility determination program for design mode may be configured as separate computer programs.

[0093] In one or more of the embodiments described above, a case where the possibility of combining two uniforms is confirmed is described in detail using soccer as an example of a sport in which players from two teams compete against each other without being separated. The uniform combination possibility determination device, uniform combination possibility determination method, and uniform combination possibility determination program according to one or more of the embodiments can also confirm the possibility of combining two uniforms for sports such as volleyball in which players from two teams compete against each other separated.
