摘要 |
<p>An N-dimensional correction space is constructed with weighting coefficients xi and eta that are used for determining reflection coefficients for an N-order target color, where the weighting coefficients xi and eta specify the lengths of the sides constituting the N-dimensional correction space, and where 2<N> reference colors are located at the corners of the N-dimensional correction space. The N-dimensional correction space is divided by N pieces of (N-1)-dimensional spaces that run through the target color, into 2<N> partial N-order correction spaces. The reflection coefficient for the target color is determined by multiplying a reference reflection coefficient with respect to each of the 2<N> reference colors by the volume of a partial N-dimensional correction space that is located at a diagonal position against a coordinate point of each reference color and summing up the results of multiplication for the 2<N> reference colors. <IMAGE></p> |
