High-fidelity color image reproduction is one of the key issues invisual telecommunication systems, for electronic commerce,telemedicine, digital museum and so on. All colorimetric standards ofdisplay systems are up to the present day trichromatic. But, from theshape of a horseshoe-area of all existing colors in the CIE xychromaticity diagram it follows that with three real reproductivelights, the stated area in the CIE xy chromaticity diagram cannot beoverlaid. The expansion of the color gamut of a display device ispossible in a few ways. In this paper, the way of increasing the numberof primaries is studied. The fourth cyan primary is added to threeconventional ones to enlarge the color gamut of reproduction towardscyans and yellow-oranges. The original method of color management forthis new display unit is introduced. In addition, the color gamut ofthe designed additive-based display is successfully compared with thecolor gamut of a modern subtractive-based system. A display with morethan three primary colors is called a multiprimary color display. Thevery advantageous property of such display is the possibility todisplay metameric colors. |
