Abstract
A color reproduction system includes a color conversion unit for displaying a color image on a multi-primary-color display. The color conversion unit includes a maximum brightness signal calculating unit for calculating signals corresponding to three color reproduction area corners as the corners of a plane that constitute a color reproduction area surface of the display. The three color reproduction area corners surround the vectors of input tristimulus values. The maximum brightness signal calculating unit also calculates a weighting factor obtained when the input tristimulus values are expressed as a linear sum of the tristimulus values of the color reproduction area corner vectors. The color conversion unit further includes a color image signal calculating unit for calculating a color image signal used to display the input tristimulus values, on the basis of the signals corresponding to the color reproduction area corners and the weighting factor. The color reproduction system can realize colorimetrically accurate reproduction, provide continuity between XYZ data and signal values, and use the color reproduction area to the maximum extent.
