Angle of incidence of reproducing light with respect to a hologram or a
holographic stereogram is adjusted so that a reproduced image can be
repetitively viewed without requiring the viewer to move his or her
viewpoint. The components of the image reproducing apparatus can be
roughly classified into a power supply unit equipped with a power supply
for generating a driving power and various types of electric circuits, a
light source unit equipped with light emitting diodes and the like, a
supporting unit for supporting the light source unit, and a holographic
stereogram display unit for holding the holographic stereogram and
displaying an image. In this image reproducing apparatus, the light source
unit is swingably or turnably moved repetitively with respect to the
holographic stereogram so that the reproducing light has angle of
incidence changed on the holographic stereogram, thus allowing change of
viewed image.
