Abstract
An optical state modulation method is provided. The method comprises steps of periodically modulating luminance of a visible light in temporal domain so as to generate an optical state variation on a recorded image that is obtained by image-capturing of a displayed image, the visible light being superposed on an original display image to produce the displayed image, the optical state variation being independent of an original display image and generating no hampering effect when the displayed image is directly watched.
