[0006] An information prompting program according to one aspect of the present invention causes a computer to perform the following steps: an acquisition step, acquiring information on the reference spectrum of a reference colorimetric material serving as a reference; a calculation step, calculating, based on the reference spectrum, a corresponding spectrum for causing a subject to produce a response consistent with or approximate to the response of a reference colorimeter's color vision system from visually recognizing the reference colorimetric material; a storage step, storing information on multiple raw material spectra corresponding to each of the multiple raw material colorimetric materials of the mixed object; a selection step, using the information on the corresponding spectrum and the information on the multiple raw material spectra to select, from the multiple raw material colorimetric materials, multiple mixed materials that emit a spectrum consistent with or approximate to the corresponding spectrum when mixed; and a prompting step, prompting the determination of information on the multiple mixed materials.

[0007] An information prompting method according to one aspect of the present invention comprises: an acquisition step, acquiring information of a reference spectrum of a reference colorimetric material serving as a reference; a calculation step, calculating, based on the reference spectrum, a corresponding spectrum for causing a subject to produce a response consistent with or approximate to the response of a reference colorimeter's color vision system from visually recognizing the reference colorimetric material; a storage step, storing information of multiple raw material spectra corresponding to each of multiple raw material colorimetric materials of a mixing object; a selection step, using the information of the corresponding spectrum and the information of the multiple raw material spectra to select, from the multiple raw material colorimetric materials, multiple mixed materials that emit a spectrum consistent with or approximate to the corresponding spectrum when mixed; and a prompting step, prompting information on the determination of the multiple mixed materials.

[0014] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the description of the drawings, the same or equivalent elements are labeled with the same symbols and repeated descriptions are omitted.

[0015] [System Overview] The information prompting system involved in this invention is a computer system or control system that provides manufacturing information when manufacturing color-developing materials that provide colors taking into account color vision diversity. Color vision diversity refers to the different states of color perception or recognition among people. The information prompting system can be used to enable people with different color vision to have a common perception of colors, or to promote mutual understanding related to color perception or recognition. Color-developing materials are materials that produce various spectral distributions of color in the visible region, such as dyes, pigments, pigments, and luminescent materials.

[0016] As for types of color vision, there are five types: C (Common), P (Protanope, red-blind), D (Deuteranope, green-blind), T (Tritanope, blue-blind), and A (Acromatic, total color blindness).

[0017] Type C is a group of photoreceptor cells containing three types of cones: L-cones, M-cones, and S-cones. L-cones are photoreceptor cells that respond with high sensitivity to long-wavelength light, such as red. M-cones are photoreceptor cells that respond with high sensitivity to medium-wavelength light, such as green. S-cones are photoreceptor cells that respond with high sensitivity to short-wavelength light, such as blue. In the case of Japanese people, 95% of men and 99% of women belong to Type C. Type C individuals are also known as normal color vision individuals.

[0018] On the other hand, people with P-type, D-type, T-type, and A-type color blindness are also referred to as colorblind individuals. P-type is composed of P-type intensity (Protanopia: red-blindness) lacking the L-cone and P-type weakness (Protanomaly: red-weakness) with sensitivity deviating from the L-cone but similar to the M-cone. D-type is composed of D-type intensity (Deuteranopia: green-blindness) lacking the M-cone and D-type weakness (Deuteranomaly: green-weakness) with sensitivity deviating from the M-cone but similar to the L-cone. T-type is the group lacking the S-cone. A-type is the group possessing only one type of cone or none at all. Among colorblind individuals, P-type and D-types constitute the majority, while T-type and A-types are extremely rare.

[0019] As an example of promoting the aforementioned shared perception or mutual understanding, an information prompting system can be used to manufacture color-developing materials that enable color-weak individuals to experience colors perceived by those with normal color vision, or to manufacture color-developing materials that achieve the opposite effect. Alternatively, an information prompting system can be used to manufacture color-developing materials that provide colors perceived equally by both those with normal color vision and those with color weakness. An information prompting system can be used to manufacture color-developing materials aimed at promoting shared perception or mutual understanding of colors among people with C, P, D, T, and A color vision types.

[0020] The information prompting system generates a corresponding color, which is another color that takes into account the diversity of color perception, based on a reference colorimetric material that serves as a reference. It also provides information about the colorimetric material used to manufacture this corresponding color. The reference color is the color specified for generating the corresponding color. In other words, the corresponding color is the color that corresponds to the reference color. In one example, the information prompting system generates a corresponding spectrum of the corresponding color based on a reference spectrum that serves as the spectrum of the reference color.

[0021] [System Structure] The information prompting system consists of one or more computers. In this embodiment, the information prompting system 1 is configured to include one computer, namely the color conversion system 10, and one computer, namely the material selection system 20. However, the information prompting system 1 may include three or more computers, or it may consist of only one computer. When multiple computers are used, these computers are connected by communication networks such as the Internet or intranets, thereby logically constructing a single information prompting system.

[0022] A computer that constitutes an information display system typically includes a processor, memory, communication interface, input devices, and output devices. Examples of processors include CPUs and GPUs. Memory can consist of flash memory, hard drives, etc. Communication interfaces can consist of network cards or wireless communication modules. Examples of input devices include keyboards, pointing devices, touch panels, microphones, sensors, and cameras. Examples of output devices include displays, touch panels, head-mounted displays (HMDs), and speakers.

[0023] An information prompting program for enabling a computer to function as an information prompting system includes program code for implementing the various functional modules of the information prompting system. This information prompting program may, for example, be provided after being non-transitorily recorded on a tangible recording medium such as a CD-ROM, DVD-ROM, or semiconductor memory. Alternatively, the information prompting program may be provided via a communication network as a data signal superimposed on a carrier wave. The provided information prompting program may be recorded in memory, for example.

[0024] refer to Figure 1 The structure of an information prompting system 1 involved in an example will be explained. Figure 1 This is a diagram showing the functional structure of the information prompting system 1. The information prompting system 1 includes a color conversion system 10 and a material selection system 20.

[0025] The color conversion system 10 is a computer system that generates a corresponding spectrum based on a reference spectrum. The color conversion system 10 consists of a single computer or multiple computers connected to each other via a communication network. The color conversion system 10 includes a processor 101 and a memory 102. In one example, the processor 101 functions as an acquisition unit 11, a response calculation unit 12, a spectrum calculation unit 13, and a generation unit 14. The memory 102 stores a predetermined reference model as data representing the color vision system of a reference color visioner. At least one of a normal color visioner and a color-deficient person is considered as the reference color visioner. The reference model can be prepared separately for both normal color visioners and color-deficient persons. When a color-deficient person is considered as the reference color visioner, the reference model can be prepared according to the type of color vision, for example, a P-type reference model and a D-type reference model can be prepared.

[0026] The acquisition unit 11 is a functional module that acquires input data (information) representing the reference spectrum, the subject model, and the consideration ratio. The subject model is data representing the subject's color vision system. The reference spectrum is the spectrum related to the reference color emitted by the reference color-developing material that serves as the reference. The subject refers to a person conceived as an object providing the corresponding color. The subject can be a person with normal color vision or a specific type of color weakness, such as type P or type D. The consideration ratio is an indicator representing the degree of change from the reference color to the corresponding color.

[0027] The response calculation unit 12 is a functional module that calculates the reference response using the response from the color vision system of a person who has visually recognized the reference color. The response calculation unit 12 calculates the reference response based on the reference spectrum and the reference model. The response corresponds to the electrical signal transmitted to the brain from the L-cone, M-cone, and S-cone via the optic nerve.

[0028] The spectral calculation unit 13 is a functional module that calculates a converted spectrum, which is used to make the subject model output a response that is consistent with or approximates a reference response. "A response that is consistent with or approximates a reference response" means a response whose difference from the reference response is below a predetermined threshold.

[0029] The generation unit 14 is a functional module that generates a corresponding spectrum based at least on the converted spectrum. In one example, the generation unit 14 generates a corresponding spectrum based on a reference spectrum, a converted spectrum, and a consideration of scale. The corresponding spectrum is a spectrum that produces a response in the subject that is consistent with or approximately similar to the reference response of a reference colorimeter who visually recognizes the reference colorimetric material.

[0030] The response calculation unit 12, the spectrum calculation unit 13 and the generation unit 14 mentioned above correspond to the calculation unit that calculates the corresponding spectrum based on the reference spectrum.

[0031] The material selection system 20 is a computer system that provides information on multiple mixed materials used to manufacture a colorimetric material, which provides a corresponding color based on a corresponding spectrum. The material selection system 20 consists of a single computer or multiple computers interconnected via a communication network. The material selection system 20 includes a processor 201 and a memory 202. In one example, the processor 201 functions as a selection unit 21 and a prompting unit 22. The memory 202 pre-stores data representing multiple raw material spectra and multiple absorption spectra, where the raw material spectra are the colorimetric characteristics of multiple raw material colorimetric materials corresponding to the mixed object, and the multiple absorption spectra are the color absorption characteristics of multiple wavelength-absorbing materials corresponding to the mixed object. The raw material colorimetric material is a material that becomes a raw material for the colorimetric material, such as dyes, pigments, chromophores, phosphors, etc. Examples of raw material colorimetric materials include azo dyes. Wavelength-absorbing materials are materials that absorb specific wavelengths when mixed with the raw material colorimetric material.

[0032] Color-producing materials made from multiple mixed materials can be luminescent materials. A luminescent material is a component that emits light through excitation energy (electrical energy, chemical energy, light energy, etc.). A luminescent material is a component manufactured in such a way that, based on information provided by the material selection system 20, it has multiple mixed materials as selected mixed materials in multiple mixing ratios. The multiple mixed materials prepared for manufacturing the luminescent material, i.e., phosphors of various colors, can be manufactured, for example, by the method disclosed as Example 1 in Japanese Patent Application Publication No. 2009-161372. The quantum dots (quantum dot phosphors) disclosed in that document have a sharp emission spectrum with a full width at half maximum (FWHM) of about 30 nm. The luminescent material thus manufactured has a corresponding spectrum based on a reference spectrum, which helps in color expression that takes into account the diversity of color perception.

[0033] Light-emitting materials, used as color-developing materials, can be used to manufacture various articles. Light-emitting materials can be phosphors or phosphors. Examples of applications include displays, signal transmitters, lighting, wavelength conversion films, backlights, indicators, luminescent dyes, luminescent coatings, or luminescent inks. By using articles containing light-emitting materials, it is possible to achieve shared color perception between people with normal color vision and those with color weakness, or to promote mutual understanding related to color recognition or identification. It also provides color-weak individuals with the same opportunities to enjoy using articles as people with normal color vision. Alternatively, it is expected that using articles containing light-emitting materials will give color-weak individuals confidence in color selection or reduce errors in color selection.

[0034] In one example, the raw material spectrum is represented by reflectance (%) at various wavelengths (nm) in the visible light region. The raw material spectrum can be expressed by a spectral function that represents the relationship between wavelength and reflectance. In another example, the absorption spectrum is represented by absorbance at various wavelengths (nm) in the visible light region. The absorption spectrum can be expressed by a spectral function that represents the relationship between wavelength and absorbance.

[0035] The selection unit 21 uses data from the corresponding spectrum, data from multiple raw material spectra, and data from multiple absorption spectra to select multiple mixed materials from multiple raw material color-developing materials and multiple wavelength absorption materials. At this time, the selection unit 21 also calculates the mixing ratio of the multiple mixed materials.

[0036] The prompting unit 22 displays information about the multiple mixed materials selected by the selection unit 21 and the mixing ratios of these materials calculated by the selection unit 21. For example, the prompting unit 22 establishes a corresponding association between one mixed material "mixed material A" and its mixing ratio "ratio A" and displays a corresponding association between another mixed material "mixed material B" and its mixing ratio "ratio B". The prompts based on the information from the prompting unit 22 can be made using the output device of the computer constituting the material selection system 20, or they can be made by sending the information from the computer constituting the material selection system 20 to an external device via a communication interface.

[0037] [Color Vision Model] Both the reference model and the subject model can be considered color vision models representing the human color vision system. In one example, the color vision model represents the sensitivity characteristics of the L-cone, M-cone, and S-cone. Sensitivity characteristics are also known as spectral characteristics. Figure 2 This is a graph showing examples of the sensitivity characteristics of each cone for individuals with normal color vision and those with color weakness. The horizontal and vertical axes of the graph represent wavelength (nm) and relative sensitivity, respectively. Figure 2 The color-deficient individuals shown correspond to type P color weakness. Compared to those with normal color vision (type C), the color-deficient individuals exhibit a greater degree of overlap in the sensitivity characteristics of their M and L cones. This difference in sensitivity characteristics leads to differences in color perception or recognition.

[0038] [spectrum] Figure 3This is a graph showing an example of a reference spectrum processed by the color conversion system 10 and the corresponding spectrum generated therefrom. The horizontal and vertical axes of the graph represent wavelength (nm) and reflectance (%), respectively. Here, an example is shown where a model using a normal color visioner is used as the reference model, and data from a P-type color-deficient individual is used as the subject model, to generate a corresponding spectrum considering a 100% proportion. As the reference spectrum 301, a spectrum with a peak at approximately 600 nm is used as the processing target, and a spectrum as the corresponding spectrum 302 is generated, which has a bottom at approximately 510 nm and a flat characteristic in the wavelength region above 630 nm.

[0039] [System Operation] refer to Figure 4 The information prompting method executed by information prompting system 1 is described. Figure 4 This is a flowchart representing an example of the operation of the information prompting system 1 as a processing flow S1.

[0040] In step S11, the acquisition unit 11 acquires the reference spectrum, the subject model, and the consideration ratio. In one example, the user of the color conversion system 10 inputs the reference color of the reference color-developing material, the subject's color perception type, and the consideration ratio. The acquisition unit 11 accepts this input and reads the reference spectrum corresponding to the reference color and the subject model corresponding to the color perception type from a predetermined storage device. Alternatively, the acquisition unit 11 may accept the input of the reference spectrum, the subject model, and the consideration ratio. Alternatively, the acquisition unit 11 may receive this data from another computer.

[0041] In one example, the reference spectrum is represented by the reflectance (%) at various wavelengths (nm) in the visible light region. The reference spectrum can be expressed by a spectral function that represents the relationship between wavelength and reflectance.

[0042] In one instance, the subject model represented as follows: Figure 2 The sensitivity characteristics of the L-cone, M-cone, and S-cone are shown. The subject model can be expressed by a sensitivity function representing the relationship between wavelength and relative sensitivity. This sensitivity function can be prepared separately for each of the L-cone, M-cone, and S-cone. As mentioned above, the subject model represents any color vision system (color vision model) in individuals with normal color vision and those with color weakness.

[0043] In one example, the consideration ratio is represented by a value greater than 0% and less than 100%. When the consideration ratio is 0%, the corresponding color is the same as the reference color. When the consideration ratio is 100%, the color perceived by the subject viewing the corresponding color is the same as or approximately the same as the color perceived by the reference colorist viewing the reference color. That is, when the consideration ratio is 100%, the subject can experience the situation of the reference colorist viewing the reference color through the corresponding color. When the consideration ratio is within a specific value or range, the color perceived by both the subject viewing the corresponding color and the reference colorist can be the same or approximately the same. This consideration ratio could be, for example, 20% or close to that value.

[0044] In one example, the acquisition unit 11 modifies at least a portion of the reference spectrum without changing the RGB values ​​of the reference color. The acquisition unit 11 can acquire the modified spectrum as the final reference spectrum. Correspondingly, the acquisition unit 11 can update the consideration scale taking into account the degree of modification, and acquire the updated consideration scale as the final consideration scale.

[0045] In step S12, the response calculation unit 12 calculates the reference response based on the reference spectrum and the reference model. The reference response can be defined by the response α from the L-cone, the response β from the M-cone, and the response γ from the S-cone. In this invention, the reference response is expressed as (α, β, γ).

[0046] In one example, the response calculation unit 12 calculates the response from the cone that perceives the reference color for each of the L-cone, M-cone, and S-cone of the reference colorimeter, as follows: The response calculation unit 12 calculates the product of the relative sensitivity of the cone at each wavelength in the visible light region and the reflectance shown by the reference spectrum. This product can be said to represent the degree of excitation. The response calculation unit 12 calculates the sum of the products at each wavelength as the response from the cone.

[0047] Let the wavelength be represented by x, and let the sensitivity functions of the L-cone, M-cone, and S-cone be represented by f, respectively. L (x), f M (x), f S (x) represents the spectral function of the reference color, which is represented by g(x). At this time, the responses α, β, and γ can be expressed as equations (1) to (3), respectively.

[0048] α=∫f L (x)g(x)dx……(1) β=∫f M (x)g(x)dx……(2) γ=∫f S (x)g(x)dx……(3) That is, the response calculation unit 12 can calculate the integral of the product of the sensitivity function and the spectral function in each cone as a reference response (α, β, γ).

[0049] In step S13, the spectral calculation unit 13 calculates the converted spectrum based on the reference spectrum, the subject model, and the reference response. In one example, the spectral calculation unit 13 modifies at least a portion of the reference spectrum to generate a candidate spectrum. Then, the spectral calculation unit 13 inputs the candidate spectrum into the subject model and calculates the response of the color vision system of a subject who visually recognizes the color shown by the candidate spectrum as the subject response (α´, β´, γ´). The spectral calculation unit 13 determines whether the subject response (α´, β´, γ´) is consistent with or approximately similar to the reference response (α, β, γ). The spectral calculation unit 13 modifies at least a portion of the reference spectrum and searches for subject responses (α´, β´, γ´) that are consistent with or approximately similar to the reference response (α, β, γ), and finally determines the converted spectrum. The converted spectrum can also be described as the corresponding color considering a 100% proportion.

[0050] In step S14, the generation unit 14 generates a corresponding spectrum based on the reference spectrum, the conversion spectrum, and the consideration scale. In one example, the generation unit 14 synthesizes the reference spectrum and the conversion spectrum to generate the corresponding spectrum by a linear combination based on the consideration scale. Let the reference spectrum, the conversion spectrum, and the consideration scale be represented as S... d S v r, then the corresponding spectrum S c This is expressed by equation (4). r is greater than 0 and less than 1. When r=1, that is, when the proportion is 100%, the generation unit 14 directly sets the conversion spectrum to the corresponding spectrum.

[0051] S c =(1-r)·S d +r·S v ... (4) In step S15, the selection unit 21 acquires information about multiple mixed materials related to the multiple mixed materials used to manufacture a colorimetric material having a color corresponding to a corresponding spectrum. In one example, the selection unit 21 refers to the corresponding spectrum, multiple raw material spectra corresponding to multiple raw material colorimetric materials, and multiple absorption spectra corresponding to multiple wavelength absorption materials, and selects multiple mixed materials for mixing to manufacture the colorimetric material from a plurality of pre-conceived raw material colorimetric materials and multiple wavelength absorption materials.

[0052] More specifically, the selection unit 21 calculates a superimposed spectrum by weighting and superimposing any number of raw material spectra from multiple raw material spectra and any number of absorption spectra from multiple absorption spectra, and determines whether the superimposed spectrum is consistent with or approximate to the corresponding spectrum. Then, if the selection unit 21 determines that the superimposed spectrum is consistent with or approximate to the corresponding spectrum, it selects the raw material colorimetric material and wavelength absorption material corresponding to the multiple spectra that serve as the superimposed source of the superimposed spectrum as multiple mixed materials. Furthermore, the selection unit uses the weights of each spectrum used in the calculation of the superimposed spectrum to determine the mixing ratio of the mixed materials corresponding to each spectrum. In this way, the selection unit 21 obtains information on multiple mixed materials and information on the corresponding mixing ratios as mixed material information.

[0053] In step S16, the prompting unit 22 prompts the mixed material information obtained by the selection unit 21. As an example, the prompting unit 22 establishes a corresponding association between one mixed material "mixed material A" and its mixing ratio "ratio A" and prompts the other mixed material "mixed material B" and its mixing ratio "ratio B".

[0054] According to the information prompting system 1 described above, similar to the reference colorimeter, it can calculate the corresponding spectrum that enables the subject to perceive the color of the reference colorimetric material, and based on this corresponding spectrum, select multiple mixed materials from multiple raw material colorimetric materials to achieve a spectrum that is consistent with or similar to the corresponding spectrum, and prompt information about these multiple mixed materials. Thus, manufacturing information can be provided when manufacturing colorimetric materials that provide color considering the diversity of color vision.

[0055] Furthermore, in addition to multiple raw material color-developing materials, it is possible to select from wavelength-absorbing materials multiple mixed materials that emit a spectrum consistent with or similar to the corresponding spectrum, and to provide information about these multiple mixed materials. Thus, the freedom in manufacturing information when producing color-developing materials to provide color, taking into account the diversity of color perception, is increased.

[0056] Furthermore, by considering the proportions, the desired corresponding spectrum can be calculated. As a result, for example, information on the manufacture of color-developing materials that can be perceived equally by both normal color visioners and color-deficient individuals can be provided.

[0057] Furthermore, it also provides information related to the mixing ratio of multiple mixed materials when manufacturing materials that emit a spectrum consistent with or similar to the corresponding spectrum, thus providing reliable manufacturing information when manufacturing color-producing materials that provide color while taking into account the diversity of color vision.

[0058] [Variation Example] The technology involved in this invention has been described in detail above based on various examples. However, this invention is not limited to the above examples. Various modifications can be made to the technology involved in this invention without departing from its spirit.

[0059] In the example above, the color conversion system 10 generates the corresponding spectrum based on the consideration ratio. However, if the color conversion system 10 directly sets the conversion spectrum to the corresponding spectrum, that is, if the corresponding spectrum is generated with a consideration ratio of 100%, the color conversion system 10 may not acquire or utilize the consideration ratio.

[0060] The processing order of a method executed by at least one processor is not limited to the example above. For example, some of the steps described above may be omitted, or the steps may be executed in a different order. Furthermore, any two or more of the steps described above may be combined, or some of the steps may be modified or deleted. Alternatively, other steps may be executed in addition to those described above.

[0061] In comparing the magnitude of two values ​​in this invention, either "above" or "greater than" can be used, or either "below" or "less than" can be used.

[0062] In this invention, the expression "at least one processor executes the first process, executes the second process, ... executes the nth process," or its corresponding expression, represents the concept that the executing entity of the n processes from the first process to the nth process, i.e., the processor, changes midway. That is, this expression represents the concept of two cases: the case where all n processes are executed by the same processor, and the case where the processor changes in any way among the n processes.

[0063] The articles used with the color-developing materials involved in this invention are classified into various categories. These categories include, for example, clothing / fashion, school / children's clothing, brand / advertising, toys, and others. Specific examples of articles included in these categories are described below.

Thus, the scope of items covered by this invention is broad, encompassing specific items within each category. Therefore, it can address various uses or scenarios.

[0064] [Postscript] As can be understood from the various examples above, the present invention includes the following methods.

[0065] (Note 1) An information notification system, comprising: The acquisition unit acquires information about the reference spectrum of the reference colorimetric material, which serves as the reference. The calculation unit, based on the reference spectrum, calculates a corresponding spectrum for producing a response in the subject that is consistent with or approximates the response of the color vision system of a reference colorimeter who visually recognizes the reference colorimetric material; The storage unit stores information on the spectra of multiple raw materials corresponding to each of the multiple raw material color-developing materials in the mixed object; The selection unit uses the information of the corresponding spectrum and the information of the multiple raw material spectra to select from the multiple raw material color-developing materials a plurality of mixed materials that emit a spectrum consistent with or similar to the corresponding spectrum when mixed; and The prompt section provides information on identifying the plurality of mixed materials.
