ABSTRACT:
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.sup.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.sup.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.sup.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.sup.N reference colors.
