Patent ID: 8289598

Claim:
An image recording method of recording a holographic stereogram, comprising the steps of: disposing an optical deflecting device in proximity to a hologram recording medium when it is exposed with a stripe-shaped elemental hologram; deflecting either an object beam or a reference beam in a long side direction thereof through the optical deflecting device to expose the hologram recording medium; and multiply exposing the same portion of the hologram recording medium, at least two times, with different area portions of the image area of the stripe-shaped elemental hologram, each of the area portions having non-overlapping areas and having smaller areas than the stripe-shaped elemental hologram, at different deflection angles of the optical deflecting device to cause the stripe-shaped elemental hologram recorded on the hologram recording medium to have a plurality of parallaxes in a long side direction of the stripe-shaped elemental hologram.
