摘要

Imaging techniques have been developed to better account for fluorescent emission that may accompany reflected light during capture and processing of high color-fidelity imagery from art works and important historical documents. This approach is based on sequential capture of monochrome images of the object or scene, each illuminated by a narrow spectral band from a bank of light-emitting diodes (LED's) in the ultraviolet, visible, and near-infrared spectral regions. These images contain color reference materials in the field of view, and are augmented by images in which bandpass filters are placed in the capture path. Processing of these images allows the separate contributions of reflectance and fluorescence emission in narrow wavelength bands to be recognized and quantified, which allows accounting for any fluorescence contributions during nominal reflectance imaging so that adjustments may be made in subsequent rendering. This paper describes the apparatus, capture procedures, and processing techniques that are employed. The impact of fluorescence on color fidelity during reproduction, based on deltaE calculations, is calculated and discussed for highly fluorescent pastels.
