A digital image correlation chip was developed as part of an electronic module library for real- time industrial machine vision applications. A core algorithm of the authors' systems is binary edge image correlation. The other electronic modules described in this paper include a monochrome edge detector and color edge detector. These modules were combined in a variety of ways for different applications. High efficiency, in terms of processing speed and hardware size, of the vision systems was confirmed in laboratory prototypes.
