Analysis of resolution limitation of integral photography

H Hoshino, F Okano, H Isono, I Yuyama - JOSA A, 1998 - opg.optica.org
The resolution limitation of integral photography (IP) is analyzed. Estimating the resolution
of IP measured at the viewpoint, we derive the optimum width of the aperture or lens. It is …

Gradient-index lens-array method based on real-time integral photography for three-dimensional images

J Arai, F Okano, H Hoshino, I Yuyama - Applied optics, 1998 - opg.optica.org
Because a three-dimensional (3-D) autostereoscopic image can be seen from a desired
viewpoint without the aid of special viewing glasses, integral photography (IP) is an ideal way to …

Time-alternating method based on single-sideband holography with half-zone-plate processing for the enlargement of viewing zones

T Mishina, F Okano, I Yuyama - Applied Optics, 1999 - opg.optica.org
The single-sideband method of holography, as is well known, cuts off beams that come from
conjugate images for holograms produced in the Fraunhofer region and from objects with …

An experimental stereoscopic television system equipped with high-definition television (HDTV)
facilities has been developed for basic study of future broadcasting services. A short …

A study on resolution and aliasing for multi-viewpoint image acquisition

H Hoshino, F Okano, I Yuyama - IEEE Transactions on Circuits …, 2000 - ieeexplore.ieee.org
We equate multi-viewpoint image acquisition with object sampling from different viewpoints,
and calculate the resolution of multi-viewpoint camera systems. Aliasing, which occurs with …
