Abstract

The aim of this work was to quantify how well the colours of natural scenes are reproduced by CRT and TFT-LCD display devices. Data sets of forty hyperspectral images of natural scenes were used. Each scene was represented as a distribution of points in CIELAB colour space and compared with the gamuts of common CRT and TFT-LCD display devices. The number of pixels out of gamut and the corresponding colour differences obtained after clipping all the pixels out of gamut to the closest displayable colour were computed in each case. For close or distant natural scenes of both rural and urban environments, only a small fraction of pixels, about 5%, were out of gamut for the CRT devices. For the TFT-LCD devices, however, this value increased to about 23%. The colours of natural scenes seem well matched to the chromatic properties of current CRT display devices.
