A practical 6-band still camera system for accurate color reproduction is presented. This camera system consists of a commercial digital camera and a customized color filter. Two 3-band images captured with and without the filter are used for color reproduction. Color reproduction process is carried out in GPU so that result image of color reproduction can be displayed on monitor interactively.
