Abstract:
A color signal processing apparatus includes a total amount calculating unit, a limit value calculating unit and a correcting unit. The total amount calculating unit calculates a total amount value of an input color signal in an output device color space which has, as color components, colors of coloring materials used in an output device. The limit value calculating unit calculates a limit value for limiting a total amount of a color signal, in accordance with the calculated total amount value. The correcting unit corrects the input color signal in the output device color space so that the total amount value of the input color signal becomes the calculated limit value or less.
