Image-motion detection using analog VLSI

Motion detection by differentiating the output currents of photosensors arranged in a 2D array is described. Subnanoampere current differentiation is made possible by the use of a novel current-mirror (CM) differentiator that requires only four MOSFETs. The pixel density of the motion-detecting imag...

Zusammenfassung:Motion detection by differentiating the output currents of photosensors arranged in a 2D array is described. Subnanoampere current differentiation is made possible by the use of a novel current-mirror (CM) differentiator that requires only four MOSFETs. The pixel density of the motion-detecting imager is higher than 40 pixels/mm/sup 2/. Experimental results of the CM differentiator are reported.< >
