Color conversion

摘要

A conversion parameter computing section (11) computes conversion parameters corresponding to a position included in a partial space with one edge thereof equal to w/2 (where w is a lattice interval). When L*a*b* value for an input color is inputted, an intra-lattice position computing section (15) computes a position in a lattice space identified by a lattice point identifying section (14) using a conversion table (13). An interpolation section (17) outputs CMY values corresponding to L*a*b* value by executing interpolation according to conversion parameters retrieved by a conversion parameter retrieving section (16). <IMAGE>
