ABSTRACT:
Characterizing a color imaging system involves generating color values representing colors of output samples of the color imaging system. The color values are converted into a device-independent color coordinate system using an adjustable white reference vector and a black reference vector. The white reference vector is calculated using the black reference vector. Color values can be transformed between color imaging systems using the device-independent color coordinate system.
