Paper Abstract

Colorimetric calibration techniques were studied for scanners that do not adhere to colorimetric requirements (the Luther condition) from the aspects of accuracy and signal noise. A newly developed calibration technique was compared with conventional polynomial regression models and was found to be more accurate. Computer simulations were performed to find the relationship between scanner responsivities and resultant chroma noise. The scanner matching the Luther condition exhibits larger chroma noise than a scanner having three separated responsivities due to the overlap among responsivities of each channel.
