Influence of Noise on the Colorimetric Calibration of an Image Acquisition Device and Its Measure for Evoluation

Abstract

Color image data from an image acquisition device are transformed to colorimetric values to achieve device independent color reproduction at an early stage in a color management system. This transformation is usually called colorimetric calibration or color correction. The accuracy of the calibration depends on its spectral sensitivities of a set of color sensors and noise present in a device. In this article, a measure to evaluate the influence of noise on the accuracy of calibration is described and a method is discussed to predict the influence using prior knowledge of spectral properties of sensor sensitivities, reflectances of objects and illuminants is available.
