Patent ID: 8049892

Claim:
A method comprising: disposing a material between a filter and a plurality of backings, each backing comprising a different color; receiving light from a plurality of sections of the material at a digital imaging device, each section disposed over a different one of the backings, the light comprising a defocused image of the material, the light in the defocused image comprising an average light from the material; filtering the light into at least three spectral bands using the filter, wherein different regions of the filter pass different spectral bands, the different regions of the filter arranged in a matrix having a plurality of rows and a plurality of columns; measuring the light in each of the spectral bands, wherein the light in each spectral band comprises a portion of the average light from the material falling within that spectral band; and determining at least one colorimetric quantity associated with the material using the measured light in the spectral bands, the at least one colorimetric quantity comprising at least one CIE value.
