ABSTRACT:
An image reproducing method and apparatus whereby an image with a wide angle of visibility can be reproduced from a holographic stereogram in a manner less susceptible to blurring. For reproducing an image from a holographic stereogram 80 of an edge lit system, a holographic stereogram 80 is arranged on a lateral side of a cylindrically-shaped light-introducing block 81 and a reproducing illuminating light beam 82 is illuminated on the holographic stereogram 80 via the light-introducing block 81. A reproduced image 85 is produced by a diffracted light beam obtained on diffraction of the reproducing illuminating light beam 82 transmitted through the holographic stereogram 80.
