Abstract
A method for obtaining a target color measurement using an electronic image capturing device comprising the steps of: (1) determining one or more of a field correction array, level correction vectors, a color correction matrix, and a calibration correction and; (2) adjusting a target color measurement based upon one or more of a field correction array, level correction vector, a color correction matrix, and a calibration correction to obtain a corrected color target measurement.
