As shown in Fig. 2, human eye with the wavelength for mutually different light there is 3 L of susceptibility to bore in retina Body, M cone and S cone detect incident light.L cone has susceptibility for the light near from yellow green to red wavelength, M cone has susceptibility for the light near from green to orange wavelength, and S cone is near from purple to blue wavelength Light have susceptibility.L cone, M cone and S cone export signal corresponding with the intensity of light of detection respectively.

In the colour vision model of Guth, the gangliocyte of eye uses the letter exported respectively from L cone, M cone and S cone Number, calculate the ATD ingredient of ATD color space.For example, gangliocyte calculates the intensity for the light that L cone detects and M cone is examined The value of the intensity addition of the light measured, i.e., the brightness of light is as A ingredient.Moreover, gangliocyte calculating is detected from L cone The intensity of light subtract value obtained from the intensity for the light that M cone detects as T ingredient.Moreover, gangliocyte is calculated from S The intensity for the light that cone detects subtracts value obtained from the intensity for the light that L cone and M cone detect as D ingredient.Also, Gangliocyte is color signal as luminance signal, D ingredient and T ingredient using calculated A ingredient to be exported to brain.Also, it is big Brain identifies the color and brightness of the object of observation based on the ATD ingredient received.

It does not function additionally, there are at least one cone missing in L cone, M cone and S cone or normally Situation.For example, L cone missing or the people not functioned normally are classified into difficult 1 type, 2 color of red and green discrimination Feel or 1 type, 3 colour vision.Moreover, the people that M cone is lacked or do not worked orderly is classified into red and green discrimination difficulty 3 colour vision of 2 type, 2 colour vision or 2 type.Moreover, S cone missing or the people not worked orderly are classified into the discrimination of blue and yellow Difficult 3 colour vision of 3 type, 2 colour vision or 3 type.Hereinafter, 1 type, 2 colour vision and 1 type, 3 colour vision are also referred to as " P (Protanope, protanope) Type colour vision ", 2 type, 2 colour vision and 2 type, 3 colour vision are also referred to as " D (Deuteranope, deuteranope) type colour vision ", 3 type, 2 colour vision and 3 types 3 colour visions are also referred to as " T (Tritanope, tritanope) type colour vision ".

In color processing apparatus 100 shown in Fig. 1, the colour vision model based on Guth, by the tristimulus of XYZ colour system Value XYZ is established as formula (1) with the ATD ingredient of ATD color space and is associated with.

[formula 1]

In addition, tristimulus values X ' Y ' Z ' expression has carried out the transformed tristimulus values XYZ of Judd.M is by tristimulus values X ' Y ' Z ' is transformed into 3 × 3 matrixes of the tristimulus values LMS of LMS color space, for example, indicating as formula (2).

[formula 2]

[formula 3]

In addition, the H of the type of each colour vision is not defined with the matrix of ingredient shown in formula (3)~formula (6), preferably root It is suitably determined according to the situation for being applicable in color processing apparatus 100.

In addition, m corresponds to various visual perception phenomenons and the coefficient that is adjusted, in order to correspond to the bright of above threshold grade The consciousness phenomenon of degree and 3 × 3 matrixes that such as formula (7) indicates like that.

[formula 4]

In addition, the H of p-type colour vision shown in formula (4)~formula (6)_P, D type colour vision H_DAnd the H of T-type colour vision_TIt is L cone respectively Body, M cone or S cone missing are the H when symptom of colour vision is most heavy.However, the symptom of colour vision due to according to each cone missing or The degree that does not work orderly and change, therefore personal difference is big.Therefore, for the people of p-type colour vision, the colour vision of D type or T-type colour vision Even if being applicable in any one H in formula (3)~formula (6), it is also difficult to reproduce the view mode in whole colour visions.

Therefore, in order to reproduce the view mode in whole colour visions and by the H in p-type colour vision, the colour vision of D type and T-type colour vision As formula (8)~formula defines (10).

H=k_PH_P+(1-k_P)H_C…(8)

H=k_DH_D+(1-k_D)H_C…(9)

H=k_TH_T+(1-k_T)H_C…(10)

Next, in step s 110, tristimulus of first transformation component 10 for the object color obtained in the step s 100 Value XYZ carries out Judd transformation, finds out the tristimulus values X ' Y ' Z ' for having carried out Judd transformation.Then, the first transformation component 10 is according to color The type and colour vision intensity of feel will carry out pair of Judd transformation using any one formula of formula (8)~formula (10) and formula (1) As the tristimulus values X ' Y ' Z ' of color is transformed to the ATD ingredient of ATD color space.

In addition, the first transformation component 10 is whenever being transformed to ATD ingredient for the tristimulus values XYZ of object color, by object color Tristimulus values XYZ carries out Judd transformation, but Judd transformation also can be omitted.

Next, in the step s 120, calculation part 20 is with the ATD ingredient of the object color converted in step s 110 On the basis of, calculate the ATD ingredient with defined color difference.

Here, the color difference Δ E such as formula between 2 ATD ingredients (A1, T1, D1), (A2, T2, D2) in ATD color space (11) it is found out shown in by the geodesic integral between 2 ATD ingredients.

[formula 5]

DE indicates the slight distance in geodesic curve, is indicated by (dA2+dT2+dD2) 1/2/r.r₁And r₂Indicate ATD ingredient The length of the vector of the vector and ATD ingredient (A2, T2, D2) of (A1, T1, D1).R is indicated from origin (0,0,0) to ATD ingredient Distance until (A, T, D).θ is indicated formed by the vector of ATD ingredient (A1, T1, D1) and the vector of ATD ingredient (A2, T2, D2) Angle (radian).

Also, by the way that formula (11) to be standardized with threshold value, color difference Δ E is indicated as formula (12).In addition, W is Weber fraction is set as 0.01 equal value.

[formula 6]

Calculation part 20 by ATD ingredient (A1, T1, D1) as the ATD ingredient of object color in the case where, use formula (12) count Calculating color difference Δ E becomes the ATD ingredient (A2, T2, D2) of defined color difference (for example, Δ E=1 etc.).

In addition, in the case where defined color difference is set as " 0 ", it is convenient to omit the processing of step S120.

Next, in step s 130, the second transformation component 30 uses the type and colour vision of colour vision identical with step S110 Intensity, formula (1) will be transformed into the tristimulus of XYZ colour system by the calculated ATD ingredient (A2, T2, D2) of step S120 Value.Color processing apparatus 100 is for corresponding with output device 300 to by the transformed tristimulus values execution of the second transformation component 30 SRGB etc. color adjustment, exported to output device 300.Then, color processing apparatus 100 terminates color treatments.
