Abstract
Most imaging sensors have limited dynamic range
and hence are sensitive to only a part of the illumi-
nation range present in a natural scene. The dynamic
range can be improved by acquiring multiple images of
the same scene under di erent exposure settings and
then combining them. In this paper, we describe a cam-
era design for simultaneously acquiring multiple images
of the same scene under di erent exposure settings. The
cross-section of the incoming beam from a scene point
is partitioned into as many parts as the desired degree
of split. This is done by splitting the aperture into mul-
tiple parts and directing the light exiting from each in
