Abstract

An analog technique for image processing that provides 2-dimensional edge detection is described. The algorithm implemented is the Sobel operator using a 3 × 3 array of picture elements. The implementation is unique in that a fully integrated circuit approach is employed which has the potential of being integrated directly into either an optical or infrared sensor. The n channel charge-coupled device (c.c.d.) technology used results in a processor area of less than 0.06 cm2, and can provide an increase in processing speeds of several orders of magnitude over general-purpose machines. Typical results from this processor are given and are compared with computer simulation.
