Abstract
A picture is scrolled on a display 5 to be measured, and the scrolling moving picture is pursuit-captured by a color camera 3 so as to obtain a pursuit-captured moving picture image. A moving picture response curve using received light intensity data obtained based upon the pursuit-captured moving picture image is converted into a color moving picture response curve using emission intensity of display elements of the display 5 to be measured. The coloration of an edge part of the pursuit-captured moving picture image is decomposed into the respective color components, by which objective quantitative evaluations of color shifting can be made.
