ABSTRACT:
A holographic stereogram which includes a plurality of element holograms and which reproduces a stereoscopic image by irradiation of coherent light, wherein each element hologram is loaded with a modulation value (pattern) corresponding to the stereoscopic image, the modulation value being a one-dimensional or two-dimensional transform coefficient obtained by one-dimensional or two-dimensional sine transform or discrete sine transform of the distribution of the intensity of diffraction light expressing the stereoscopic image, enabling simplification of the drive system of the display device displaying the stereoscopic image and reproduction of the original stereoscopic image much more faithfully.
