BabelColor CRI显色性测量功能

BabelColor显色指数CRI工具可以接受仪器的测量数据或者颜色文件(不是必须测量仪器),对于颜色文件,需要包含光谱数据(5nm或者10nm间隔)

CRI显色指数测量工具由当前的CRI方法(CIE 13.3: 1995)和三种提出的指标组成:颜色质量比(CQS, NIST Version 9.0.3),CRI2012 (nCRI Version 12.0)和 TM-30-15 方法(IES, 2015)。同时,它还计算了色域(GAI: Gamut Area Index)和内存颜色(MCRI: Memory Color Rendering Index)的具体设计指标,上面的截图显示了标准CIE荧光灯#4相关的测试结果,下面是您从这种度量中得到的数据的列表。

  • 测试源数据:CCT(K)、Duv(CIE1960)、亮度(lux)、LER(lm/W)、反射率
  • CRI显色指数:A graph of the 14 individual indices and Ra; numerical values of Ra (a general score based on the first 8 indices and better known as the current CRI), R9, R(9-14) (for indices 9 to 14) and R(1-14) for indices 1 to 14; a graph of the samples (a*, b*) coordinates; a representation of the samples illuminated by the Reference and Test sources; the CIELAB color difference between the patches.
  • CQS颜色质量比 (Color Quality Scale, NIST Version 9.0.3):A graph of the 15 individual indices and Qa; numerical values of Qa (general score based on the 15 indices), Qf (fidelity index) and Qg (relative gamut area); a graph of the samples (a*, b*) coordinates; a representation of the samples illuminated by the Reference and Test sources; the CIELAB color difference between the patches.
  • CRI2012 (nCRI Version 12.0):A graph of the 17 individual indices and Ra,2012; numerical value of Ra,2012 (based on the 17 indices); a graph of the samples (a’M, b’M) coordinates; a representation of the samples illuminated by the Reference and Test sources; the color difference between the patches.
  • TM-30-15 (IES, 2015):Numerical values of the Fidelity Index (Rf), the Gamut Index (Rg); the fidelity index for skin (Rf,skin), the color fidelity (Rfces) for each of the 99 Color Evaluation Sample (CES), the color fidelity (Rfh) for each of the 16 Hue Angle Bins, the chromaticity coordinates (J’a’b’) of all CES reference and test patches, the color difference (DeltaE’) for each set of CES patches, the average chromaticity coordinates (a’M, b’M)) of the Hue Angle Bins, and of the normalized chromaticity data used to draw the Color Vector Graphic (CVG). A graph of the reference source, which is different from the source used in other color rendering metrics when the CCT is between 4500 K and 5500 K; a bar graph of the color fidelity by sample (Rfces); a bar graph of the color fidelity by Hue Angle Bin (Rfh); a graph of the average chromaticity (a’M, b’M)) of the reference and test data of the Hue Angle Bins, which is used to compute the gamut area; a Color Vector Graphic (CVG) used to evaluate color saturation and desaturation; a plot of Rg versus Rf; and a visual representation of the 99 CES reference and test patches.
  • GAI色域指数 (Gamut Area Index):GAI 指标
  • GAI和Ra:GAI和Ra的算术平均值(当前CRI).
  • MCRI内存显色指数(Memory Color Rendering Index):Rm (general memory color quality index); Sa (degree of similarity); Si (special color quality indicators of the ten objects)
