Abstract
A high-speed analog VLSI image acquisition and pre-
processing system has been designed and fabricated in a 0.35
m
standard CMOS process. The chip features a massively parallel
architecture enabling the computation of programmable low-level
image processing in each pixel. Extraction of spatial gradients and
convolutions such as Sobel or Laplacian filters are implemented
on the circuit. For this purpose, each 35
m
35
m pixel in-
cludes a photodiode, an amplifier, two storage capacitors, and an
