Abstract:
A computer readable medium encoded with a computer program arranged such that, upon execution of the computer program, a processor performs a method for recalibrating a multi-color imaging system, wherein the imaging system is capable of forming different colors based on input color values, and wherein the input color values control amounts of the colors formed by the imaging system, the method comprising:controlling the imaging system to form different color combinations by combining two or more of the different colors;controlling a measuring device to measure color values for each of the different color combinations;comparing each of the measured color values to corresponding reference color values, the reference color values representing a calibrated condition of the imaging system;calculating an error value representing a deviation of the measured color values from the reference color values; andadjusting one or more of the input color values to reduce the error value to a predetermined degree, wherein the adjustment of the input color values for one of the colors is performed independently of the adjustment of the input color values for others of the colors.
