One of the key technologies of color management is colorimetric characterization for digital imaging devices. According to the principle of colorimetric characterization of digital imaging device, the non-linear relationship between the RGB of digital imaging device and the CIE Lab of standard colorimetry value is established by means of polynomial regression method. Meanwhile, under Matlab software programming, a fast modeling software has been designed for colorimetric characterization of digital image processing devices. The experimenta
