The Foveon color image sensor has three photo-sensing layers. The spectral sensitivities of the three layers are extremely different from those of the RGB primary color filters. The color signals acquired by the Foveon sensor should be transformed to RGB color signals. For that purpose, we propose a new color transformation method. First, our method recovers the multi-spectral reflectance of each imaged color from its acquired color signals by solving the ill-posed problem with the regularization technique, and then transforms the multi-spectral reflectance to RGB color signals. We evaluate the performance of our method by computer simulations.
