【摘要】 比较多种光源色域面积指标,研究3种常用的光源色域面积指标的关系.选取48个光源,用其光谱进行数值计算,计算其全色域指数(GAI)、光色品质色域面积(CQS_QG)指标和IES-TM-30-15相对色域面积(RG),并分析这3个色域面积之间的关系.结果表明:QG值与RG值的相关性最高,GAI值与QG值,RG值的相关性都不高;光源色域面积计算中,采用的颜色样本,颜色空间和参考光源对计算结果都有很大的影响.更多还原

【Abstract】 The various gamut area index of light sources are compared and the relationship of three common gamut area index were studied. 48 light sources were selected for numerical calculation using their spectrum. The gamut area index(GAI), QG of the color quality scale(CQS_QG) and RG of the IES-TM-30-15 relative gamut of these light sources were calculated, and the correlations among the three color gamut areas index were analyzed. The results showed that the correlation between QG and RG was the highest, while the correlation between GAI and QG or RG was low. Additionally, the color sample set, color space and reference illuminant have a significant influence on the quantification of gamut area.更多还原
