19.4: Color Management Technologies on WideGamut Display Devices with MultiPrimary Colors

Abstract

We propose two color management systems for the cases of 1) RGB input signals to RGB-based display devices and 2) RGB input signals to multi-primary color (MPC) display devices. For RGB to RGB, our algorithm reproduces "memory colors" as expected and also uses the capability of a display device. For RGB to MPC, we solve a problem causing the hue angle difference between input signals and an MPC display. This realizes faithful hue reproduction as expected in an input image in addition to impressively wide-gamut of an MPC system.

Multi‐primary image projector using programmable spectral light source

“…Multiband displays and projectors have been proposed for overcoming the limitations on chromaticity and spectral characteristics of RGB‐based image reproduction systems . For displaying accurate yellow and cyan colors, five primary liquid crystal displays had been developed by adding yellow and cyan primary to RGB primary colors .…”
