Abstract

A color signal processing apparatus and method calculate without errors a control vector that is a driving signal of a multi-primary display (MPD) corresponding to an input color signal in order to reproduce the input color signal on the MPD using at least four primary colors. The color signal processing apparatus includes: an XYZ color signal conversion unit; a parallel processing unit that obtains a polyhedron corresponding to a color gamut of the MPD in the CIE-XYZ color space based on an MPD Forward Model, divides the polyhedron into plural pyramids, and outputs intermediate values for calculating the control vector based on the plural pyramids; a restriction condition checking unit that outputs a valid value satisfying a physical restriction condition out of the calculated intermediate values and outputs an index for a pyramid for which the valid value is calculated; a pattern arrangement unit; and a control vector arrangement unit.
