Light field imaging and display have attracted a great attention in the field of 3D image acquisition,
processing, and display. To develop a light field acquisition and display system is a great challenge
because the acquisition/display devices require tens or hundreds of higher numbers of ‘pixels’ than
conventional 2D imaging and display devices. In this paper, we point out that computational
photography and display technologies can be a solution for the problem. By combining the conventional
2D acquisition/display devices and associated computation, we can reduce the number of pixels for
acquisition/display of the light field. We first introduce ray space concept and address light field
acquisition/display as sampling and reconstruction of ray space data. Then we show how such
compressive acquisition and compressive display can be realized in terms of ray space data acquisition
and display.
