Generalized Image Acquisition and Analysis
A Reconfigurable Camera Add-On for High Dynamic Range, Multispectral, Polarization, and Light-Field Imaging
We propose a non-permanent add-on that enables plenoptic
imaging with standard cameras which we refer to as
KaleidoCamera. Our design is based on a physical copying
mechanism that multiplies a sensor image into a number of
identical copies that still carry the plenoptic information
of interest. Via different optical filters, we can then
recover the desired information. A minor modification of the
design also allows for aperture subsampling and, hence,
light-field imaging. As the filters in our design are
exchangeable, a reconfiguration for different imaging
purposes is possible. We show in a prototype setup that high
dynamic range, multispectral, polarization, and light-field
imaging can be achieved with our design.

Abstract
After decades of research on digital representations of
material and object appearance, computer graphics has more
recently turned to the problem of creating physical
artifacts with controllable appearance characteristics.
While this work has mostly progressed in two parallel
streams – display technologies as well as novel fabrication
processes – we believe there is a large overlap and the
potential for synergies between these two approaches. In
this report, we summarize research efforts from the worlds
of fabrication display, and categorize the different
approaches into a common taxonomy. We believe that this
report can serve as a basis for systematic exploration of
the design space in future research.
