abstract: The CMOS image sensor computes
spatially-compressing convolutional transforms directly on the focal
plane, yielding digital output at a rate proportional to the mere
information rate of the video. A bank of column-parallel
DeltaSigma-modulated analog-to-digital converters (ADCs) performs
distributed columnwise focal-plane oversampling of a set of adjacent
pixels and concurrent weighted average quantization. The number of
samples per pixel and switched capacitor sampling sequence order set the
amplitude and sign of the respective pixel coefficient. Outputs of a set
of adjacent ADCs are accumulated to realize a two-dimensional block
matrix transform in parallel for all columns. The 3.1 mm times 1.9 mm
prototype, ViPro, containing a 128times128 active pixel array and a bank
of 128 hybrid algorithmic DeltaSigma-modulated ADCs yields 4 GMACS
(multiply-and-accumulates per second) computational throughput in
real-time discrete cosine transform (DCT) video compression when scaled
to HDTV 1080i resolution
