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 conversion device is provided including: a setting unit that sets a conversion mode, based on characteristics of a source color region related to an input image signal in a color space, for converting the input image signal to an image signal that falls within at least one color region from a plurality of color regions that have been defined in the color space; and a conversion unit that converts the input image signal in accordance with the conversion mode into the image signal that falls within the color region.

Abstract: In an image processing apparatus, a first conversion unit converts, on the basis of an input device profile, input data into first device-independent data expressed by a color space that is independent of an apparatus. A storage unit stores plural conversion profiles for converting using a color appearance model in the color space that is independent of the apparatus in correspondence with plural device characteristics that are dependent on apparatuses. A selection unit selects a conversion profile corresponding to characteristics of the input device, characteristics of an output device, observation conditions of the input data and the output data. A second conversion unit converts, on basis of the selected conversion profile, the first device-independent data into second device-independent data. A third conversion unit converts the second device-independent data into the output data on the basis of an output device profile.
