Abstract:
1. A color gamut boundary information generating device comprising: at least one processor; at least one memory, the at least one memory storing instructions that when executed cause the at least one processor to perform as: a mapping unit that maps boundary points existing at a plurality of 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, each boundary point being mapped by: a triangulating unit that performs triangulation on the inside of a convex hull including a plurality of points in the two-dimensional region obtained by the mapping unit, thereby generating triangulation information, which is a result of the triangulation; and a generating unit that generates color gamut boundary information on the basis of the triangulation information generated by the triangulating unit, the color gamut boundary information being information that specifies a three-dimensional shape in the color space, the three-dimensional shape having a boundary including the boundary points.
