Abstract
Most imaging sensors have a limited dynamic range
and hence can satisfactorily respond to only a part of il-
lumination levels present in a scene. This is particularly
disadvantageous for omnidirectional and panoramic
cameras since larger elds of view have larger bright-
ness ranges. We propose a simple modi cation to exist-
ing high resolution omnidirectional/panoramic cameras
in which the process of increasing the dynamic range
is coupled with the process of increasing the eld of
view. This is achieved by placing a graded transparency
(mask) in front of the sensor which allows every scene
point to be imaged under multiple exposure settings as
