16. Focal-Plane Algorithmically-Multiplying CMOS Computational Image Sensor

Abstract—The CMOS image sensor computes two-dimensional
convolution of video frames with a programmable digital kernel
of up to 8 8 pixels in parallel directly on the focal plane. Three
operations, a temporal difference, a multiplication and an accumulation
are performed for each pixel readout. A dual-memory pixel
stores two video frames. Selective pixel output sampling controlled
by binary kernel coefficients implements binary-analog multiplication.
Cross-pixel column-parallel bit-level accumulation and frame
differencing are implemented by switched-capacitor integrators.
Binary-weighted summation and concurrent quantization is performed
by a bank of column-parallel multiplying analog-to-digital
converters (MADCs). Asimple digital adder performs row-wise accumulation
during ADC readout. A 128 128 active pixel array
integrated with a bank of 128 MADCs was fabricated in a 0.35 m
standard CMOS technology. The 4.4 mm 2.9 mm prototype
is experimentally validated in discrete wavelet transform (DWT)
video compression and frame differencing.
Index Terms—Block-matrix image transform, CMOS image
sensor, focal-plane image processing, multiplying algorithmic
ADC.
