Abstract: A color gamut boundary information generating device includes a receiving unit, a tetrahedralizing unit, a first generating unit, and a correcting unit. The receiving unit receives pieces of coordinate information indicating points in a color space. The tetrahedralizing unit performs a tetrahedralization process. The first generating unit generates boundary information, which is a set of outermost triangular faces among triangular faces obtained through the tetrahedralization process. The correcting unit selects a target face from among the triangular faces included in the boundary information, regards a tetrahedron including the target face as a target tetrahedron, determines whether or not the target tetrahedron satisfies a condition, and, if the target tetrahedron does not satisfy the condition, selects the triangular faces included in the target tetrahedron except the target face, eliminates the target face from the boundary information, and adds the selected triangular faces to the boundary information, thereby correcting the boundary information.

Abstract: A device includes a setting section that sets a single-color amount limit and an ink total amount limit, an upper half outline constructing section, a lower half outline constructing section, a restricting outline constructing section, and a color space converter. The upper half outline points are points at which one or more color components are 0% and that satisfy the single-color amount limit and the ink total amount limit. The lower half outline points are points at which one or more color components satisfy the single-color amount limit and that satisfy the ink total amount limit. The restricting outline points satisfy the single-color amount limit and the ink total amount limit, and are connected to the upper or lower half outline points which satisfy the single-color amount limit and the ink total amount limit. The color space converter converts the constructed outline points into another color space.

Abstract: A color gamut boundary information generating device includes a mapping unit, a triangulating unit, and a generating unit. The mapping unit maps boundary points existing at plural coordinates in a color space that is independent of an output device to corresponding points in a two-dimensional region while maintaining respective phases of the boundary points. The triangulating unit performs triangulation on the inside of a convex hull including plural points in the two-dimensional region obtained by the mapping unit, thereby generating triangulation information, which is a result of the triangulation. The generating unit generates color gamut boundary information on the basis of the triangulation information generated by the triangulating unit. The color gamut boundary information is information that specifies a three-dimensional shape in the color space, the three-dimensional shape having a boundary including the boundary points.

Abstract: An image processing system includes a profile generating section, a designating section, a calculating section and a correcting section. The profile generating section generates a color conversion profile based on first colorimetric values obtained from a first color chart output from a target device and second colorimetric values obtained from a second color chart from an output device other than the target device. The calculating section calculates difference information between a first data value obtained by converting a designated color into a device-independent color space and a second data value obtained by converting the designated color using the color conversion profile into a second color and converting the second color using the device-independent color space. The correcting section corrects the first colorimetric values based on the difference information. The profile generating section generates the color conversion profile again based on the corrected first colorimetric values.

The correcting section corrects the first calorimetric values based on the difference information. The profile generating section generates the color conversion profile again based on the corrected first colorimetric values.
