    • An image display device of the present invention is provided with a liquid crystal display panel for displaying an image in accordance with an input of a chrominance signal, a sensor for sensing light characteristics of external light, and a chrominance signal converter for converting a chrominance signal to be inputted into an image display section in accordance with an output of the sensor. The chrominance signal converter includes a target display color setting section for setting a color to display as an image agreeable with chromatic adaptation characteristics of human, according to the output of the sensor, and a color reproduction section for reproducing a target color set by the target display color setting section, by using three primary color with chromaticities suitable for the output of the sensor. The target display color setting section converts the chrominance signal into a chrominance signal of the target display color reproduced by the color reproduction section. Provided is an image with color tone, in which no change is sensed by a user, even if external light condition, that is the light characteristics of the external light.
    • 本发明的图像显示装置设置有用于根据色度信号的输入显示图像的液晶显示面板,用于感测外部光的光特性的传感器和用于转换色度信号的色度信号转换器 根据传感器的输出被输入到图像显示部。 色度信号转换器包括目标显示颜色设置部分,用于根据传感器的输出设置显示为与人的色彩适应特性一致的图像的颜色;以及色彩再现部分,用于再现由目标设定的目标色彩 显示颜色设置部分,通过使用适合于传感器输出的色度的三原色。 目标显示颜色设定部分将色度信号转换成由色彩再现部分再现的目标显示颜色的色度信号。 提供了一种具有色调的图像,其中即使外部光条件,即外部光的光特性也不会由用户感测到变化。
