Abstract
Color gamut is one of the most important performance indicators of multimedia systems because a wide color gamut enables the reproduction of more real surface colors. The color gamut of multimedia systems depends on the RGB (red-green-blue) primary. There are various RGB primaries, such as ITU-R BT.709, ITU-R BT.2020, sRGB, Adobe RGB, and DCI-P3. ITU-R BT.709 and sRGB have a very small color gamut, while ITU-R BT.2020 has an extremely wide one. Adobe RGB and DCI-P3 have RGB primaries with the characteristics of color printers and digital cinema projectors, respectively. Also, some of these RGB primaries are not compatible with each other. Thus, the contents of a system should be converted for use in other systems. This paper proposes an RGB primary for use in various multimedia systems. In the proposed method, sRGB, Adobe RGB, and DCI-P3 - the most frequently used RGB primaries - are unified. In this paper, the color gamut efficiency and human visual preference of the proposed RGB primary are checked. The proposed RGB primary is expected to be utilized as an international-standard RGB primary for multimedia systems.
