Method of colorimetrically calibrating an image capturing device

摘要

A method of calculating a set of color-correction matrix coefficients for an image capturing device uses an LED illuminator having programmable output characteristics and spectral characteristics. A first XYZ data set is created from computed tristimulus values for each of the object stimulus. An image of each one of the predetermined set of object stimulus is captured thereby producing a plurality of images. RGB values are determined and normalized for each image thereby creating an RGB data set. A set of color-correction matrix coefficients are then calculated for the RGB data set corresponding to the first XYZ data set, thereby producing a color corrected RGB data set.
