Abstract. The goal of this work is to build video cameras whose spa-
tial and temporal resolutions can be changed post-capture depending on
the scene. Building such cameras is difficult due to two reasons. First,
current video cameras allow the same spatial resolution and frame rate
for the entire captured spatio-temporal volume. Second, both these pa-
rameters are fixed before the scene is captured. We propose different
components of video camera design: a sampling scheme, processing of
captured data and hardware that offer post-capture variable spatial and
temporal resolutions, independently at each image location. Using the
motion information in the captured data, the correct resolution for each
