Abstract
We have developed integral three-dimensional (3D) television using an
ultra high definition imaging system. The system uses a device having 7680
pixels in the horizontal direction and 4320 pixels in the vertical direction
for each of the red, green, and blue channels. A lens array comprising 400
lenses is configured in the horizontal direction and one comprising 250
lenses is configured in the vertical direction. The system is designed to
ensure a maximum spatial frequency of 11.3 cycles/degree and a viewing angle
of 24 degrees when the display is observed from three times the display
height. The setup described here has simultaneously maintained the balance
between the maximum spatial frequency and the viewing angle by shortening
the focal length of the elemental lens while narrowing the pitch of the
elemental lens. We have confirmed the generation of 3D images with an
appearance that varies in a natural manner according to the position of the
observer.
