Color display system with accurate conversion between the RGB and XYZ colorimetric systems

摘要

A processing system capable of executing a precise conversion between RGB colorimetric system and XYZ colorimetric system in a display device and a display apparatus having such function are provided. Fig.4 is a block structure diagram illustrating a color display system for a display device according to the present invention. A correction device 1 in Fig.4 sets display parameters in such a manner that distortion error, which is caused by nonlinearity inherent in the display device or the like, is minimized, thereby correcting the XYZ to RGB conversion. A display device 2 displays, with the minimized distortion, an image signal of RGB colorimetric system outputted from the correction device 1. This correction processing allows any types of display apparatuses to achieve color specification of reproduced images with the minimized distortion.
