Abstract:
A method for calibrating at least one non-reference imaging device to a reference imaging device, comprising the steps of:determining a set of 1-D characteristic functions for each non-reference imaging device, each set relating a plurality of primary colors of that non-reference imaging device with a plurality of color elements of an input device; determining a set of 1-D characteristic functions for the reference imaging device relating a plurality of primary colors of the reference imaging device with a plurality of color elements of the input device; determining a set of 1-D transfer functions in the form of a set of 1-D look-up tables for each non-reference imaging device based on the determined set of 1-D characteristic functions for the reference imaging device and the determined set of 1-D characteristic functions for that non-reference imaging device; and applying each set of 1-D look-up tables to the corresponding non-reference imaging device to calibrate that non-reference imaging device to the reference imaging device.
