Description

[Technical Field]

[0001] One aspect of the present invention relates to a color design support device, method, and program that support the design of color schemes for information transmission media such as guide signs, printed materials, and homepages. [Background technology]

[0002] In recent years, visual information transmission technology has become more sophisticated and diverse, and information is now provided using a variety of color combinations. However, color vision varies from person to person, and certain color schemes can result in visual information not being conveyed correctly. For example, some colors are difficult to distinguish for people with different color vision than the average person, or for people whose color vision has declined with age. For this reason, when designing color schemes for information transmission media, it is important to take into account the diversity of human color vision.

[0003] Therefore, in the past, the color scheme for an object was determined by the following procedure: first, a color scheme was provisionally set for people with normal color vision, then the provisional color scheme was checked to see how it would look to people with color vision different from that of the general public, and any colors that were determined to have a problem with their appearance as a result of this check were corrected (see, for example, Non-Patent Document 1). [Prior art documents] [Non-patent literature]

[0004] [Non-Patent Document 1] "Tokyo Metropolitan Government Color Universal Design Guidelines," Community Welfare Promotion Division, Department of Life and Welfare, Bureau of Social Welfare and Public Health, Tokyo Metropolitan Government, Internet<URL: https: / / www.fukushi.metro.tokyo.lg.jp / kiban / machizukuri / kanren / color.html> , published in March 2011 Summary of the Invention [Problem to be solved by the invention]

[0005] However, the color scheme method described in Non-Patent Document 1 takes into consideration how to enable people with color vision different from that of normal color vision to correctly recognize information, but does not take into consideration aspects such as design and beauty.

[0006] Furthermore, Non-Patent Document 1 also describes another color scheme method that uses only colors included in a pre-recommended color scheme set. However, this method limits the number of colors that can be used even by people with normal color vision, and the flexibility of color schemes is lost, making it difficult to create color schemes that take design and beauty into consideration.

[0007] In general, the design and beauty of color schemes are extremely important factors, as they affect the ability to convey information to both people with color vision deficiencies and those with normal color vision.

[0008] This invention was made with the above-mentioned circumstances in mind, and aims to provide a technology that enables highly flexible color arrangements for both those with color vision deficiency and those with normal color vision, thereby ensuring design and beauty and improving information transmission. [Means for solving the problem]

[0009] To solve the above problems, a first aspect of a color design support device or support method according to the present invention, when supporting the design of a color scheme for an information communication medium, acquires reproduction color information of colors distinguishable by the color vision corresponding to each of a plurality of types of color vision and information representing color confusion lines. In this state, when a first color vision classified as a color vision deficiency is designated among the color visions, first, a first color distinguishable by the designated first color vision is selected from the reproduction color information corresponding to the first color vision. Next, a second color different from the first color and suitable for a general second color vision is acquired, selected by a user based on the color confusion lines corresponding to the first color vision and including the first color. The first color is corrected based on the acquired second color.

[0010] According to a first aspect of the present invention, when a first color vision classified as a color vision deficiency is designated as a color vision for which a color scheme is to be set, a first color suitable for the first color vision is first selected. Next, colors that correspond to the first color vision and are on a confusion color line that includes the first color are presented to a user, and the first color is corrected based on a second color that is different from the first color and suitable for a general second color vision, selected and input by the user. As a result, it is possible to propose a color scheme that is distinguishable by a first color vision person classified as a color vision deficiency, for example, and has excellent information transmission properties that are eye-catching for general color vision people.

[0011] A second aspect of the color design support device according to the present invention, when supporting the design of a color scheme for an information communication medium, acquires reproduction color information of colors distinguishable by the color vision corresponding to each of a plurality of types of color vision and confusion color line information, which represents a confusion color line using an xy function formula in an xy chromaticity space. In this state, when a first color vision classified as a color vision deficiency is designated from among the plurality of types of color vision, a first color distinguishable by the designated first color vision is selected based on the reproduction color information corresponding to the first color vision. Next, a second color different from the first color and suitable for a general second color vision is selected based on the xy function formula representing the confusion color line corresponding to the first color vision and including the first color.

[0012] According to the second aspect of the present invention, a second color that is different from the first color and that is adapted to general second color vision is automatically selected, thereby reducing the burden on the designer in selecting colors. [Effects of the Invention]

[0013] In other words, according to one aspect of the present invention, it is possible to provide a technology that enables highly flexible color schemes for both people with color vision deficiency and people with normal color vision, thereby ensuring design and beauty and improving information transmission.

DETAILED DESCRIPTION OF THE INVENTION

[0015] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0016] [One embodiment] (Configuration example) One embodiment of the present invention uses an information processing device such as a personal computer to assist a color designer (also called a user) in designing color schemes for information transmission media such as guide signs and printed materials installed at stations and event venues, or websites.

[0017] 1 and 2 are block diagrams showing an example of the hardware and software configurations of a color design support device TM according to an embodiment of the present invention.

[0018] The color design support device TM is configured by, for example, a general-purpose personal computer used by a designer. The color design support device TM may also be configured by a server computer located on the web or in the cloud.

[0019] The color design support device TM includes a control unit 1 that uses a hardware processor such as a central processing unit (CPU). A storage unit having a program storage unit 2 and a data storage unit 3, a communication interface (hereinafter, interface will be referred to as I / F) unit 4, and an input / output I / F unit 5 are connected to the control unit 1 via a bus 6.

[0020] The communication I / F unit 4 transmits and receives information data to and from a web or cloud site (not shown) or another information processing terminal, in accordance with a communication protocol defined by a network including the Internet or an intranet, for example.

[0021] The input / output I / F unit 5 performs input / output processing of input information and display information between the input device 7 and the display device 8. The input device 7 is made up of, for example, a keyboard and a mouse, and is used by the designer to input various requests related to color scheme design, color specification information, etc. to the color design support device TM.

[0022] The display device 8 is composed of a display using, for example, liquid crystal or organic EL (Electro Luminescence) and is used to display color samples of correction candidate colors presented by the color design support device TM during the color scheme design process, as well as display information of information transmission media colored with the corrected color scheme combination.

[0023] The input / output I / F unit 5 may be connected to an external storage medium such as a USB (Universal Serial Bus) memory.

[0024] The program storage unit 2 is, for example, a combination of a non-volatile memory such as an HDD (Hard Disk Drive) or SSD (Solid State Drive) as a storage medium that can be written to and read from at any time, and a non-volatile memory such as a ROM (Read Only Memory), and stores application programs necessary to execute various processes related to one embodiment of the present invention, in addition to middleware such as an OS (Operating System).

[0025] The data storage unit 3 is, for example, a combination of a non-volatile memory such as an HDD or SSD as a storage medium that can be written to and read from at any time, and a volatile memory such as a RAM (Random Access Memory), and the storage area thereof is provided with a color vision-specific reproduction color storage unit 31, a color confusion line information storage unit 32, and a color combination information storage unit 33.

[0026] The color vision-specific reproduced color storage unit 31 is used to store reproducible colors created for each color vision. The reproduced colors for each color vision are the overall image of colors recognized by a person with color vision classified as color vision deficiency (hereinafter also referred to as a person with color vision deficiency) when he or she views all hues, and are assumed to be an infinite number of colors. The reproduced colors for each color vision are expressed as combinations of specific distinguishable colors, but may also be expressed as combinations of different confusion color lines distinguishable by a person with color vision deficiency.

[0027] The color confusion line information storage unit 32 stores programs for creating color confusion line information that have been created in advance for each type of color vision. The information representing the color confusion lines for each type of color vision is, for example, an xy function that shows the relationship between x (red) and Y (green) on the CIE (International Commission on Illumination) xy chromaticity diagram.

[0028] The color scheme combination information storage unit 33 is used to store color scheme combination information generated by the color scheme design support process performed by the control unit 1.

[0029] The control unit 1 includes, as processing units according to an embodiment of the present invention, a color vision-specific reproduction color acquisition processing unit 11, a color confusion line information acquisition processing unit 12, a color vision type designation information acquisition processing unit 13, a color scheme combination provisional setting processing unit 14, a color scheme combination correction processing unit 15, and a color scheme combination information output processing unit 16.

[0030] The processing units 11 to 16 are all realized by causing a hardware processor of the control unit 1 to execute an application program stored in the program storage unit 2. Note that some or all of the processing units 11 to 17 may be realized using hardware such as an LSI (Large Scale Integration) or an ASIC (Application Specific Integrated Circuit).

[0031] The color vision-specific reproduction color acquisition processing unit 11 acquires color vision-specific reproduction colors via the communication I / F unit 4 from, for example, an information site that manages color design guide information, and stores the acquired color vision-specific reproduction colors in the color vision-specific reproduction color storage unit 31 by linking them to color vision type information.

[0032] The confusion color line information acquisition processing unit 12 acquires a confusion color line information creation program, which has been created in advance for each type of color vision, from the information site via the communication I / F unit 4, and stores the acquired confusion color line information creation program in the confusion color line information storage unit 32. Note that if the confusion color line information creation program has been stored in advance in the confusion color line information storage unit 32, there is no need to acquire the program.

[0033] The color vision type designation information acquisition processing unit 13 receives, via the input / output I / F unit 5, information designating the type of color vision classified as color vision deficiency, for example, input by the designer via the input device 7. The color vision type designation information acquisition processing unit 13 may also have a function to acquire information representing the information transmission medium before coloring.

[0034] The color combination provisional setting processing unit 14 sets color combinations for color vision deficiency people, reads color vision-specific reproduction colors corresponding to the type of color vision specified by the color vision type specification information from the color vision-specific reproduction color storage unit 31, selects color combination candidates that can be distinguished by color vision deficiency people based on the read color vision-specific reproduction colors, and enables the designer in charge of color design to provisionally set the color combinations. Note that the color combination provisional setting processing unit 14 may autonomously set the color combination candidates without presenting the color combination candidates to the designer.

[0035] The color combination correction processing unit 15 corrects the color combination provisionally set for color vision deficiency by the color combination provisional setting processing unit 14 so that it is suitable for people with normal color vision who do not fall under the category of color vision deficiency (hereinafter also referred to as normal color vision deficiency), and stores information representing the corrected color combination in the color combination information storage unit 33. An example of the color combination correction processing will be described in the operation example.

[0036] The color combination information output processing unit 16 reads out color combination information from the color combination information storage unit 33, generates display information for an information transmission medium colored using the read color combination, and outputs the generated display information from the input / output I / F unit 5 to the display device 8 for display.

[0037] (Example of operation) Next, an example of the operation of the color design support device TM configured as above will be described.

[0038] Here, we will explain the example of protanopes (hereinafter referred to as protanopes) with mutations in the red (L) cones, deuteranopes (hereinafter referred to as D-type color vision) with mutations in the green (M) cones, and tritanopes (hereinafter referred to as T-type color vision) with mutations in the blue (S) cones, and will focus on protanopes in particular, and propose color combinations that are suitable for both protanopes and people with general color vision.

[0039] FIG. 3 is a flowchart showing an example of the processing procedure and processing contents of the color scheme design support processing executed by the control unit 1 of the color design support device TM.

[0040] (1) Acquisition of reproduced colors for each color vision For example, suppose that a person in charge of color scheme design inputs a color scheme assistance request via the input device 7.

[0041] When the control unit 1 of the color design support device TM detects the color scheme support request in step S10, first in step S11, under the control of the color vision-specific reproduction color acquisition processing unit 11, it accesses, for example, an information site that manages color design information, and acquires information representing color vision-specific reproduction colors from the information site via the communication I / F unit 4. Then, it associates the acquired information representing color vision-specific reproduction colors with color vision type information and stores it in the color vision-specific reproduction color storage unit 31.

[0042] Figure 4 shows examples of the color vision characteristics of people with normal color vision, people with P-type color vision, and people with D-type color vision. As shown in this example, the combinations of "blue" and "purple," "light blue" and "pink," "gray" and "light green," "dark green" and "brown," "dark red" and "burnt brown," "red" and "green," and "yellow" and "yellowish green" are distinguishable by people with normal color vision, but are difficult for people with P-type color vision and people with D-type color vision to distinguish.

[0043] In other words, P-type and D-type color vision individuals have difficulty distinguishing between colors in the "green" and "red" systems, as shown in Figure 5, but can distinguish between colors in the "blue" and "green" systems.

[0044] Therefore, taking into consideration the characteristics of color vision of P-type and D-type color vision persons, a boundary line TH1 is set between the "blue" system and the "green" system, and color combinations are selected from the color areas on either side of this boundary line TH1, and the selected color combination is used as a color scheme for P-type or D-type color vision persons. TH0 indicates the center of the area of colors that are difficult for P-type and D-type color vision persons to distinguish.

[0045] In the above explanation, an example was given in which color vision-specific reproduction colors corresponding to all types of color vision were acquired, but it is also possible to specify the color vision of the design target in advance and acquire only the color vision-specific reproduction colors corresponding to the specified type of color vision.Furthermore, instead of acquiring color vision-specific reproduction colors from an information site each time the color scheme support process is executed, it is also possible to continuously use color vision-specific reproduction colors that have been stored once.

[0046] (2) Acquisition of a program for creating color confusion line information Next, in step S12, the control unit 1 of the color design support device TM, under the control of the confusion color line information acquisition processing unit 12, acquires a previously created confusion color line information creation program via the communication I / F unit 4, and stores the acquired confusion color line information creation program in the confusion color line information storage unit 32. Note that if the confusion color line information creation program has been previously stored in the confusion color line information storage unit 32, the acquisition process is omitted.

[0047] Figure 6 shows the CIExy chromaticity diagram, which shows a standard chromaticity distribution, and an outline of the confusion lines corresponding to P-type color vision, D-type color vision, and T-type color vision based on this chromaticity diagram. In this diagram, each straight line in the two-dimensional chromaticity xy space is a confusion line, and each of these confusion lines can be expressed by an xy function.

[0048] Although colors on the color confusion line appear different to people with general color vision, they will appear confused as the same color to people with dichromatic color vision, such as people with P-type color vision or D-type color vision. In other words, when a color distinguishable for people with P-type color vision or D-type color vision is selected, any color on the color confusion line that includes this color can be substituted, and a variety of colors can be presented to people with general color vision while maintaining the color distinguishability for people with P-type color vision or D-type color vision. The color design support device TM performs the color scheme correction process described below by focusing on this characteristic.

[0049] Figures 7 and 8 show specific examples of color confusion lines corresponding to protanopia and deuteranopia, respectively. Note that protanopia has a mutation in the red (L) cones, making it difficult for people with protanopia to recognize the color "red" with a wavelength of 670 nm or more, as shown in Figure 7. For this reason, reds with wavelengths of 670 nm or more are excluded from the color confusion lines.

[0050] (3) Preliminary color combination For example, when designing a color combination that takes into consideration people with color vision deficiencies for an information transmission medium such as a homepage, the designer inputs the type of color vision for which the design is to be performed and template data for the information transmission medium before coloring using the input device 7.

[0051] In response to this, when the control unit 1 of the color design support device TM detects the input of the designation of the color vision type in step S13 under the control of the color vision type designation information acquisition processing unit 13, in step S14, under the control of the color scheme combination provisional setting processing unit 14, firstly reads out color vision-specific reproduction colors corresponding to the color vision designated by the color vision type designation information from the color vision-specific reproduction color storage unit 31. Then, the color scheme combination provisional setting processing unit 14 selects and provisionally sets a color scheme combination that can be distinguished by people with the designated color vision, based on the read out color vision-specific reproduction colors.

[0052] For example, if P-type color vision is specified as the type of color vision for which the color scheme is being designed, the color scheme combination provisional setting processing unit 14 reads out the color vision-specific reproduction colors prepared for P-type color vision, and presents the read out color vision-specific reproduction colors to the person being designed, thereby enabling the person being designed to select a color scheme combination.

[0053] Figure 9 shows a color sample of an example of a color combination selected for P-type color vision. In this example, "blue," "light blue," "brown," "dark brown," and "yellow" are selected. All of these colors are color combinations that P-type color vision people can distinguish.

[0054] (4) Correcting color combinations Next, under the control of the color combination correction processing unit 15, the control unit 1 of the color design support device TM executes the process of correcting the provisionally set color combination as follows.

[0055] That is, first, in step S15, the color combination correction processing unit 15 calculates, for each of the colors constituting the provisionally set color combination, a color confusion line that corresponds to the color vision type designated by the designer and includes the provisionally set colors, using a color confusion line information creating program stored in the color confusion line information storage unit 32. Then, on the calculated color confusion line, a plurality of colors different from the provisionally set colors are selected as correction candidate colors.

[0056] More specifically, the color combination correction processing unit 15 first uses the color confusion line information creation program to calculate color confusion line information using the x and y values of the provisionally set color in the xy chromaticity space as parameters, and displays the color confusion line information on the display device 8 in step S16 to present it to the designer in charge of color design. The designer in charge of color design selects correction candidate colors within a convertible range using the xy function representing the color confusion line information, taking into consideration the design, and inputs the selected correction candidate colors. In this way, the designer can select correction candidate colors from all colors defined on the color confusion line.

[0057] When presenting the correction candidate colors, the color combination correction processing unit 15 displays the correction candidate colors using, for example, a slider so that the designer can select any color from an infinite number of candidate colors while checking the effects. Note that instead of using a slider, display sample information of a medium reflecting the correction candidate colors may be generated and presented.

[0058] When the designer operates to specify a correction candidate color, the color scheme combination correction processing unit 15 receives, in step S17, the specification information of the specified and input correction candidate color via the input / output I / F unit 5. Then, the color scheme combination correction processing unit 15 corrects the previously provisionally set color based on the specified and input correction candidate color. More specifically, the provisionally set color is replaced with the specified and input correction candidate color.

[0059] For example, when correcting the color combination provisionally set for P-type color vision shown in Figure 9, the colors are corrected to be more eye-catching for people with normal color vision, for example, "blue" to "purple," "light blue" to "pink," "brown" to "green," "dark brown" to "red," and "yellow" to "yellow-green." Figure 10 shows an example of applying such corrections to the color scheme of the word "Color."

[0060] Subsequently, in step S18, the color scheme combination correction processing unit 15 stores information representing the color scheme combination after correction in the color scheme combination information storage unit 33. The color scheme combination correction processing unit 15 performs the above-described correction process for each of the colors constituting the provisionally set color scheme.

[0061] (5) Output of color combination information Finally, in step S19, under the control of the color combination information output processing unit 16, the control unit 1 of the color design support device TM reads information representing the result of the color combination from the color combination information storage unit 33, and outputs the display information of an information transmission medium such as a homepage, which has been colored based on the read color combination information, from the input / output I / F unit 5 to the display device 8 for display.

[0062] The control unit 1 of the color design support device TM repeatedly executes a series of steps S13 to S19 for each input of a new color vision type until a request to end the design support process is input. Then, when it detects in step S20 that a request to end the design support process has been input, the process ends.

[0063] (effect) As described above, in one embodiment, first, color vision-specific reproduction colors corresponding to the type of color vision and a color confusion line information creation program prepared for each color vision, such as a program using an xy function formula in xy chromaticity space, are acquired and stored in the color vision-specific reproduction color storage unit 31 and the color confusion line information storage unit 32, respectively, in the data storage unit 3. Then, when the type of color vision to be designed is specified and input in this state, the designer is first prompted to select a color combination for people with color vision deficiency based on the color vision-specific reproduction colors corresponding to the type of color vision, and the selected color combination is provisionally set. Next, based on the xy function formula of the color confusion line information creation program corresponding to the type of color vision and including the provisionally set colors, correction candidate colors suitable for people with normal color vision are displayed on the display device 8 from the color confusion line by changing parameters so that multiple colors can be selected from an infinite number of colors. The provisionally set color combination is then corrected based on the correction candidate colors selected by the designer, and the display information of the information communication medium colored using the corrected color combination is displayed on the display device 8.

[0064] Therefore, according to one embodiment, it is possible to propose to designers color combinations that are highly designable even for people with P-type color vision or D-type color vision, which are classified as color vision deficiencies, and that are also likely to attract the eye of people with normal color vision, i.e., have excellent information transmission properties.

[0065] [Other embodiments] (1) In one embodiment, color samples of all colors on the color confusion line, excluding the colors provisionally set for color vision deficiency, are presented to the designer, allowing the designer to select and specify any color. However, it is also possible to select multiple correction candidate colors from the color confusion line and present them to the designer, and obtain information representing the color selected by the designer from the multiple colors presented.

[0066] (2) In the embodiment, the case where the correction candidate color is selected based on the xy function formula representing the color confusion line has been described as an example. However, the present invention is not limited to this. For example, data representing multiple color samples included on the color confusion line may be stored in advance in the color confusion line information storage unit 32, and a desired color may be selected as the correction candidate color from among the multiple stored color samples.

[0067] (3) In one embodiment, a case has been described in which a series of color combination design processes are performed each time color vision type information is input. However, for example, each time the color combination design process is completed, the correction results of the color combination, such as the number of selections or selection frequency, can be saved in the data storage unit 3 for each color vision as correction history information. When the next design process is performed, a recommendation level can be set for each previously selected color according to the number of selections or selection frequency based on the correction history information corresponding to the target color vision, and correction candidate colors can be selected and presented according to this recommendation level.

[0068] (4) In one embodiment, the reproduced colors for each color vision are acquired and stored. However, for example, the reproduced colors for each color vision created by the designer may be acquired. Also, the color design support device TM may independently create and store the reproduced colors from color universal design color samples based on information that indicates the characteristics of how colors appear for each color vision.

[0069] (5) In one embodiment, a case is described in which colors on the confusion color line that correspond to a first color vision and include a first color are presented to a user in charge of color scheme design, and the user selects and inputs a second color that is different from the first color and is suitable for a general second color vision from the presented colors on the confusion color line.

[0070] However, the present invention is not limited to this, and the control unit 1 may automatically select a second color that is different from the first color and is suitable for general second color vision based on the xy function formula of the color confusion line. In this case, for example, colors previously selected by the user may be saved as a selection history, and the color that has been selected most frequently may be automatically selected based on this selection history. In this way, it is possible to select a color that meets the user's desire while reducing the burden on the user required for color selection. The automatic correction color selection process can also be realized by the control unit 1 causing a processor to execute a program.

[0071] (6) In addition, various modifications can be made to the type and functional configuration of the color design support device, its processing procedures and processing contents, the type of color vision and the configuration of the corresponding color scheme recommendation information, etc., without departing from the spirit of this invention.

[0072] Although the embodiments of the present invention have been described in detail above, the above description is merely an example of the present invention in every respect. It goes without saying that various improvements and modifications can be made without departing from the scope of the present invention. In other words, when implementing the present invention, specific configurations according to the embodiments may be appropriately adopted.

[0073] In short, this invention is not limited to the above-described embodiments, and the components can be modified and embodied in practice without departing from the spirit of the invention. Furthermore, various inventions can be formed by appropriately combining multiple components disclosed in the above-described embodiments. For example, some components may be omitted from all the components shown in the embodiments. Furthermore, components from different embodiments may be appropriately combined.
