Patent ID: 8411941

Claim:
A color processing apparatus for making interpolation computations of output signals for N≧3, an integer)-dimensional vector signals which represent an image using a lookup table and an N-dimensional tetrahedron interpolation or hypertetrahedron interpolation, comprising: a divider, configured to divide N components included in the N-dimensional vector signals into upper bit signals and lower bit signals; a plurality of memories which divisionally store output signals corresponding to vertices of unit solids or unit hypersolids which configure the lookup table in eight-vertex units; a memory controller, configured to control the plurality of memories to obtain output signals of vertices of the unit solid or the unit hypersolid corresponding to a combination of the upper bit signals of the N components; and a computing section, configured to make the interpolation computations of the output signals for the N-dimensional vector signals based on the obtained output signals and the lower bit signals of the N components.
