ABSTRACT:
A method for displaying a color image under various illuminants is provided. In the color image displaying method, the chromaticity of an illuminant existing in a space in which a predetermined display device is located and the luminance ratio of a white paper on the display under the illuminant with respect to a luminance of the display device are measured. A shift ratio of a visual white of the display device using the chromaticity and the luminance ratio is determined. A new visual white of the display device in which the influence of the illuminant is removed using the shift ratio is obtained. A white of a displayed color image on the display device is shifted to the new visual white. Therefore, a visually consistent color image can be reproduced on the color display device under any illuminant.
