中文摘要:
      目的 本文旨在探讨不同年龄段的个体色度观察者在特定视场条件下色适应变换结果的分布规律。方法 划分连续的不同年龄构成的分组观察者,基于Monte Carlo算法和个体色度观察者模型拟合生成相应年龄分组下的模拟个体观察者,继而在设定的视场条件对各年龄分组观察者进行色适应变换。结果 得到年龄跨度20~70岁的5个年龄分组下,共计5 000位拟合个体色度观察者,在设定视场条件下的60万组对应色预测结果。结论 设定条件下,年龄分组个体观察者的色适应结果分布存在分化,其对不同色调参考色的敏感度也存在差异。此外,标准色度观察者与个体色度观察者的色适应结果在特定条件下存在不同程度的偏差。
英文摘要:
      The work aims to explore chromatic adaptation transformation rules of individual colorimetric observers grouped by different ages under specific view conditions. Observers were grouped in a continuous way according to different ages to generate individual observers based on the Monte Carlo algorithm and an individual colorimetric observer model. Then, chromatic adaptation transformations were then carried out on those modelling observers under certain view conditions. 5000 individual observers of five age groups ranging from 20 to 70 years old were generated. The prediction results of 600,000 sets of corresponding color under certain view conditions were obtained. It is found that chromatic adaptation results of individual observers are differentiated within different age groups. They also show color specificity in different references. Moreover, there are different degrees of deviations between the color adaptation results of standard colorimetric observer and individuals corresponding to different conditions.
