Abstract:
1. An image display device comprising: an image display section for displaying an image in accordance with an input of a chrominance signal; and a chrominance signal converter for converting the chrominance signal to be inputted into the image display section, in accordance with light characteristics of external light incident upon the image display section, the chrominance signal converter including a target display color setting section which uses information regarding the light characteristics of the external light to generate a target display color chrominance signal indicative of a color to display on the image display section for providing an image which agrees with human chromatic adaptation characteristics by referring to tristimulus values of light to which a human vision system adapts as the external light changes; and wherein, from wavelength distribution characteristics of external light and optical wavelength distribution characteristics, chromaticity coordinates values of the three primary colors are determined for external light, and correction is performed on the chrominance signal so that image display is carried out based on the chromaticity coordinates.
