A New Color Conversion Algorithm for Digital Camera Based on Fourier Basis Functions

Color management for digital camera is one of the key techniques in color image reproduction in computer multimedia processing. A New color management model is presented based on analyzing color rendering principle of digital camera. First, the paper takes standard color target for experimental sample and substitutes color blocks in color shade district for complete color space, which solves the difficulties of selecting experimental color target. Second, data collecting method is introduced and some data bases for deducing the model are created. Then, the color management model based on neural network with fourier basis functions is deduced and analyzed and some methods are adopted to speed up model convergence and to simplify model structure. Finally the experimental results show that the model can improve digital camera color management accuracy and can be used in its color management practically.
