abstract: Several recent studies in compressive video
sensing have realized scene capture beyond the fundamental trade-off
limit between spatial resolution and temporal resolution using random
space-time sampling. However, most of these studies showed results for
higher frame rate video that were produced by simulation experiments or
using an optically simulated random sampling camera, because there are
currently no commercially available image sensors with random exposure
or sampling capabilities. We fabricated a prototype complementary metal
oxide semiconductor (CMOS) image sensor with quasi pixel-wise exposure
timing that can realize nonuniform space-time sampling. The prototype
sensor can reset exposures independently by columns and fix these amount
of exposure by rows for each 8×8 pixel block. This CMOS sensor is not
fully controllable via the pixels, and has line-dependent controls, but
it offers flexibility when compared with regular CMOS or charge-coupled
device sensors with global or rolling shutters. We propose a method to
realize pseudo-random sampling for high-speed video acquisition that
uses the flexibility of the CMOS sensor. We reconstruct the high-speed
video sequence from the images produced by pseudo-random sampling using
an over-complete dictionary. The proposed method also removes the
rolling shutter effect from the reconstructed video.
