This paper describes electronic holography that can record and reconstruct real objects. Images of objects were captured by integral photography (IP) . Object beams were obtained from the captured images by simulating an IP reconstructed optical system. The beam reproduced by IP with a wide viewing zone was divided horizontally into three ranges in the direction of propagation, and each beam was recorded in a separate hologram. In holographic reconstruction, three holograms were displayed in another liquid crystal panel with a pixel pitch of 6.8 μm and 4096 (horizontal) ×2400 (vertical) pixels and illuminated by a He-Ne laser. The horizontal viewing zone was enlarged by combining each reconstructed beam from LC panels, and three-dimensional holographic images of real, moving objects could be seen with both eyes at a distance of 40 cm.
