Device-Independent Imaging System for High-Fidelity Colors
This device-independent imaging system consists of a camera, which can accurately capture colors, and a display device, which can faithfully reproduce colors. To accurately capture colors, a camera with three sensors and three filters like conventional digital cameras was enhanced with color-spec***m sensitivities to satisfy the Luther-Ives condition. As a result, the camera captures colors with very high accuracy (for example, delta E = 0.27 in CIE L*a*b* for MacBeth Color Checker). The display component is a multi-primary color (MPC) display that employs more than three primaries (RGB + Yellow and Cyan in this case) to reproduce a wider color gamut with higher efficiency than conventional RGB-based displays. It can reproduce 99% of the existing material colors, most of which are located out of the color gamut of conventional display devices and cannot be reproduced correctly. The camera outputs signals in device-independent format (for example, XYZ), and the display prototype accurately reproduce those colors. The whole procedure, from capturing to reproducing images, works in real time.
