Abstract: A color processing apparatus includes an obtaining unit, a setting unit, and a color converting unit. The obtaining unit obtains a predetermined corresponding relationship between total amount limit information regarding limitation of a total amount of inks of colors, and a combination in which, among droplet diameters of inks of colors ejectable to satisfy the total amount limit information, droplet diameters of at least two or more inks are made uniform, and the types of droplet diameters of inks of the colors are two or fewer types. The setting unit sets the combination of droplet diameters corresponding to the accepted ink total amount limit information, on the basis of the obtained corresponding relationship. The color converting unit converts a color in an input color gamut reproducible by an input device into a color in an output color gamut in accordance with the set combination of droplet diameters.

Abstract: A color processing apparatus includes a correction unit. When, among colors on a color gamut boundary from a lowest-lightness color on an achromatic color axis to a highest-chroma color in a predetermined color space in an output color gamut of an output device in the color space, there exist a high-lightness color whose lightness is higher than that of the highest-chroma color and a color with the same lightness as that of the high-lightness color but with different chroma, and when there exists a low-lightness color whose lightness is lower than that of the lowest-lightness color on the achromatic color axis in the color space, the correction units corrects the low-lightness color to a higher lightness side higher than that of the lowest-lightness color on the achromatic color axis.

Abstract: A color adjustment device includes a color-value obtaining unit, a color-property-value deriving unit, a correction-item selection unit, a target-property-value setting unit, a correction-coefficient deriving unit, and a color-adjustment-profile generating unit. The color-value obtaining unit obtains color values when an image is displayed on image display devices. The color-property-value deriving unit derives values of color properties from the color values. The correction-item selection unit selects a color property as a correction item on the basis of the derived values. The target-property-value setting unit sets a target property value for the correction item. The correction-coefficient deriving unit derives a correction coefficient to be used to correct the values of the color property to the target property value. The color-adjustment-profile generating unit generates a color-adjustment profile on the basis of the correction coefficient.

Abstract: An image adjusting apparatus includes the following elements. A set color temperature obtaining unit obtains a set color temperature which is set when a white image is displayed, in an image display apparatus. A maximum tone value calculator calculates a maximum tone value of a reference color when the displayed white image is changed into a white image corresponding to the set color temperature. A tone characteristic setting unit sets a tone characteristic of the reference color on the basis of the calculated maximum tone value. If the calculated maximum tone value is decreased from a maximum tone value before the set color temperature is set, the tone characteristic setting unit corrects, in a region in which a tone value of an input image signal is equal to or smaller than a predetermined value, the tone characteristic so that a tone value of an output image signal is increased.

Abstract: 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.

Abstract: 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.

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.
