Paper Abstract

An imaging system has been demonstrated which captures a 3D scene with six parallax images using only one stationary CCD. The parallax effect is achieved either by imaging through a pinhole which is translated in front of the CCD or by imaging through a solid-state ferroelectric shutter which simulates a translatable pinhole. A single set of six compatible images is referred to as a single autostereoscopic image; the images so captured are presented on an autostereoscopic display. An autostereoscopic display system provides the perception of depth by presenting several images on the display over a range of viewing angles. When viewed at the correct distance from the display, a different image is perceived by each eye. With suitable images, this results in the illusion of depth without using stereoscopic eyewear. Improvements in the imaging/display rate and miniaturization of the camera assembly will produce a system compatible with use in laparoscopic surgery.
