Abstract
A color image of an object is processed so that the processed image accurately portrays the colors of the object regardless of varying exposure conditions. An object and a color chart that is comprised of a plurality of color chips having known colorimetric parameters are imaged under the same predetermined exposure conditions. Then, colorimetric parameters are determined for each imaged color chip of the imaged color chart. A correlation, between the known and the determined colorimetric parameters, is computed and, on the basis of the computed correlation, the color of the imaged object is corrected.
