ABSTRACT:
Color digital image signals generated by scanning an original or by a computer color graphics application are converted to signals representing normalized cone response values based on a color adaptation model of the human visual system. The cone response values are normalized to the white point of the input color digital image. The normalized cone response values are denormalized to the viewer adaptation point of the output viewing conditions of the output medium. The denormalized cone response values are transformed to signals for reproducing the digital color image.
