The present invention also comprises a kind of measuring method of medical display color uniformity measuring system, is described below：
The mankind can coloured concept, mainly due to different wave length light enter human eye color perception different.Can
The wave-length coverage seeing light is 380nm～780nm.For example, wavelength is the visual experience caused by light radiation entrance human eye of 700nm
It is red, wavelength is the visual experience caused by light radiation entrance human eye of 580hm is yellow, and wavelength is the light radiation of 510nm
Entering the visual experience caused by human eye is green, and wavelength is that the visual experience caused by light radiation entrance human eye of 450hm is
Blueness etc..So, the color of light is relevant with the spectral power distribution of the light radiation entering human eye, when entering into the light in eyes
Spectrum radiation wavelength changes or when their relative spectral power distributions change, human eye to the color perception of light also with
And there occurs change.
And the Method and kit for applied in colorimetry, it is all to be adopted with consistent in the world with visual color matching law
Standard based on.International Commission on Illumination (CIE), by its colorimetry committee it is recommended that colorimetry method and basic
Standard.CIE recommends one group of " CIE that the law according to Jim Glassman color mixture obtains on the basis of experiment within 1931
Standard colorimetric observer's spectral tristimulus value " data, and 1931CIEXYZ has been obtained according to the linear transformation of this color system
Colorimeter system.
In engineer applied and actual production it has been found that human eye to the susceptibility of different wave length spectrum color distortion with
The different difference range of wavelengths are very big.For example, interval in wavelength 490nm-600nm, the ability of the distinguishing colours of human eye is very high,
As long as the difference that wavelength has 1nm just can be discovered, but, the poor ability of human eye distinguishing colours interval in wavelength 430nm-650nm, when
The change of color just can be realized during wavelength change 5-6nm of spectrum.
Color matching function according to CIE regulation in 1931WithAs following equation：
Wherein,
S(λ)：The relative spectral power distribution of light source
：CIE standard observer color matching function (1931), color matching function is three thorns of equal energy spectrum
Swash value, be the function of wavelength, these functions are consistent with the sensitivity of human eye.
R(λ)：The spectral reflectance of style, depending on material attribute itself
Further, xyz chromaticity coordinate is to be calculated according to the following formula by XYZ tristimulus values to get：
Thus obtain CIE 1931 xy chromaticity diagram, as shown in figure 1, in figure coordinate axess unit is 1, ellipse can not for human eye
The color aberration scope of identification, transverse direction is saturation, and ellipse short shaft direction is tone.
Fig. 2 is CIE 1976 UCS chromaticity diagram, and this chromaticity diagram is attempted providing one kind to exist for the roughly the same color of brightness
The visually more uniform colour space.In figure coordinate axess unit is 1, and the color aberration scope that ellipse can not identify for human eye is ellipse
Circle long axis direction is saturation, and ellipse short shaft direction is tone.In this UCS chromaticity diagram u and v value can according to the following formula by
Tristimulus values XYZ or calculated by chromaticity coordinate xy：
Wherein, X, Y, Z are tristimulus values, and x, y are the chromaticity coordinate in CIE 1931 xy chromaticity diagram.
The uniform color space set up on CIE 1976 UCS even color figure, can represent identical in same distance
The aberration of consciousness.The L*u*v* colour space (the also referred to as CIE LUV colour space) be CIE in regulation in 1976 several uniform colour spaces it
One, L*, u*, v* value can be calculated by following equation：
U*=13L* (u'-u'0)
V*=13L* (v'-v'0)
Wherein, Y is tristimulus values Y, and u', v' are the chromaticity coordinates in CIE 1976 UCS chromaticity diagram, Y0And u'0、
v'0It is tristimulus values Y and chromaticity coordinate u', v' of total reflection diffuser.
In the L*u*v* colour space, aberration Δ E*uvThe degree of aberration is described, but is not direction, it is determined by following equations：
Wherein, Δ L*, Δ u*, Δ v* are the differences of L*, u*, v* value between style color and aim colour
Colour difference formula Δ E* using the definition of CIE LUV uniform colour spaceuv, can be used to evaluate liquid crystal display in L*u*
The color homogeneity of display under v* color space.Further, realize medical display never with color space converting into target
After color space, i.e. L*u*v* color space, Δ E*uvMay also indicate that the color even of medical display color space conversion
Property, i.e. the degree of color aberration.
As shown in table 1, what Δ E value reflected is the size of gap between medical display actual measured value and standard value, because
This its numerical value is the smaller the better, fraction higher explanation color more distortion.
Table 1 uses Δ E value to assess medical display color uniformity error synopsis
As long as shown in figure 3, measurement numerical value under different color space for the display, such as sRGB color space, Adobe
Rgb color space, CIE XYZ color space, CIE LAB color space and other color spaces, are then computed being transformed into
CIE LUV color space, and calculate different color space corresponding Δ E under CIE LUV color space using said method, just
Can measure and assess the color uniformity of different color space conversion.
In sum, measure and assess color error under different color space for the medical display, i.e. medical display
The color uniformity of color space conversion, needs to build a complete medical display color uniformity measuring system, first
Measurement obtains medical display data that is a great deal of and reaching certain scale under different color space, then sets up not homochromy
There is under color space the tables of data of mapping relations, secondly calculate the data from a kind of input of color space according to these tables of data
It is mapped to the data of another kind of target color space output, and another kind of target color space is shown on above-mentioned medical display
The data exporting, measurement afterwards obtains the data of another kind of target color space output, finally with being actual measured value and theory
Value of calculation compares, and obtains the distribution situation of the color uniformity error of above-mentioned medical display.
