摘要：

Directly recovering the spectral information of surface colors using digital camera signals is important for color reproduction under various illuminating conditions. The RGB signals for color samples were obtained by a commercial digital camera under two different CIE illuminants, D65 and A, to reconstruct their corresponding spectral reflectance based on the algorithm combining principal component analysis (PCA) and polynomial model. The experimental results indicate that the spectral reconstruction accuracy could be improved by simultaneously utilizing the RGB signals under the two illuminants, in which case the metameric characteristics of color pairs could also be well reproduced.
