Paper Abstract

As the spectral sensitivities of most color devices are typically different from that of human vision or corresponding output devices, signals from different channels (such as Red, Green and Blue) of a color recording device need to be properly mixed to generate color information suitable for viewing. The mixing (or transformation) which minimizes some error measure between the target and the transformed colors of a large set of color patches is normally used for this purpose. As the color error is the only criterion in determining such transformation, the measurement noises of the color device may often be amplified in the target color space without much control. We present in this paper a new color correction method that takes account of both the color error and the noise variance in reproduced images. This method is useful in applications where the measurement noises of recording devices are not necessarily low. The proposed method is then extended to include other color reproduction constraints. Analytical solutions and experimental results of the proposed method are both reported in the paper.
