摘要
本文讨论了3种相关色温的计算方法,它们是比较距离找对应黑体点法,黑体轨迹的Tchebycheff近似法和利用等温线交点找对应等温线法。所有这些方法都具有计算速度快、精度高、数据量少的特点。
Three methods of calculating correlated colour temperature are discussed in this article. They are fulfilled by finding the nearest blackbody chromaticity coordinates with comparison of distance by Tchebycheff approximation of blackbody locus and by finding correlated isotherm with the help of intersection points of various isotherms. All the methods are rapid in calculation speed, high in calculation accuracy and small in data amount.
