    摘要： A color gamut forming apparatus includes a reference color acquiring unit and a converted color gamut forming unit. The reference color acquiring unit sets at least a saturated color, which is reproducible on a contour of an input color gamut, as a reference input color and acquires a reference output color which is a color obtained by converting the input reference color into a color being reproducible in an output color gamut. The converted color gamut forming unit forms, in the output color gamut, a converted color gamut in which the reference output color corresponding to the saturated color on the contour of the input color gamut is a convex point.

    摘要： An image processing apparatus includes a characteristics acquisition unit that acquires some of color reproduction characteristics of additive color mixing applied in a display; and a transform method determination unit that determines a transform method from one color gamut of an input color space to another color gamut used by an output device, based on the color reproduction characteristics acquired by the characteristics acquisition unit.

    摘要： 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.
