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.
Claims17
An image reproducing method for reproducing an image from a holographic stereogram of an edge-lit system, comprising:
- arranging a holographic stereogram on a curved surface of a light-introducing block;
- directing a reproducing illuminating light beam on the holographic stereogram via the light-introducing block;
- and
- reproducing an image with a diffracted light beam that is produced when the reproducing illuminating light beam is transmitted through the holographic stereogram.
An image reproducing apparatus for reproducing an image from a holographic stereogram of an edge-lit system, comprising:
- a light-introducing block having a curved surface on which a holographic stereogram is arranged;
- wherein a reproducing illuminating light beam is illuminated via said light-introducing block to the holographic stereogram arranged on said curved surface of said light-introducing block so that an image is reproduced by the reproducing illuminating light beam being transmitted through and diffracted by the holographic stereogram.
