Abstract :
A parallel signal processing technique using MOS current-mode analog circuits for three-dimensional smart image sensors is proposed. The designed signal processing circuits for contour extraction require 79 transistors for each pixel. Prototype CMOS integrated circuits have been designed and the typical operation has been simulated by the SPICE program. The CMOS current-mode analog circuits are particularly suitable for the implementation of specific kinds of image processing such as linear special filtering.<>
