  • Publication number: 20060152718
    Abstract: To determine the spectra of objects that have different degrees of fluorescence, a plurality of reference databases are provided, each reference database being suited to a different degree of fluorescence. A most appropriate one of the reference databases is selected based on a predicted degree of fluorescence of an object for which a reflectance spectrum is to be determined. The prediction of the degree of fluorescence may be based on user input, or may be predicted by using a priori information, such as a priori knowledge of media types.

  • Publication number: 20060132777
    Abstract: An LED spectrophtometer device for determining an aspect of the color of an object may include: a visible spectrophotometer comprising a plurality of light emitting diodes that emit light in the visible spectrum onto the object; at least one detector for detecting said light after being directed onto the object and for generating an output; and a UV light emitting diode assembly that emits light in the near ultraviolet spectrum and communicates with at least one detector for generating an output. The device may further include a processor that combines the outputs of the at least one detector of the visible spectrophotometer and the at least one detector in communication with the UV light emitting diode assembly.
