1. A color reproduction system comprising:
- color conversion means for converting spectral data into display signals; and
color image display means for performing display on the basis of the display signals, wherein the color conversion means converts spectral data into display signals such that a display spectrum relating to display by the color image display means is approximated to the spectral data within the gamut of the display spectrum realizable by the color image display means.

Abstract
In a color reproduction system, under constraint conditions where colorimetric values of a subject spectrum, calculated by a colorimetric-value calculation unit (21), match colorimetric values of a display spectrum of a six-primary-color display (3), a signal calculation unit (22) calculates display signals such that squared errors between the subject spectrum and the display spectrum are minimized within the gamut of the remaining degree of freedom by using Lagrange'"'"'s method of undetermined coefficients or the reduced gradient method.
