Color management of reflective-type LCDs in terms of adaptation the human visual system to light-source variations

摘要

We have investigated the color management, in terms of the color adoption property of the human visual system, of a reflective-type TFT-LCD(R-LCD). Since the R-LCD depends on ambient light as the light source, it is expected that the colorimetric color on the R-LCD must be changed if the source for the ambient light is changed. However, due to the adaptation property of the human visual system, the eye does not perceive colorimetrically corrected colors as the same color even for an R-LCD. In this research, first, we conducted a subjective experiment to obtain the RGB code value that is required in order to display a corresponding color on the R-LCD under varying ambient-light conditions.
