Abstract
According to color measuring apparatus and method and a liquid crystal display system S of the present invention, intensity signals obtained by receiving radiant light from a liquid crystal color displayat a first viewing angle and corresponding to at least three mutually different spectral responsivities are converted into information on a plurality of primary color intensities of the liquid crystal color display, and the intensity signals by the first viewing angle are corrected to signal intensities by a second viewing angle. Thus, these color measuring apparatus and method are capable of a more accurate measurement even at a dark gradation. The liquid crystal display system can more accurately calibrate a display surfaceof the liquid crystal color displayeven at a dark gradation.
