ABSTRACT:
Serial data processing equipment useful for product inspection in a factory automation system stores. Data concerning the number of picture elements above a threshold value which should be detected in each of sequentially divided visual fields or window areas of the product being inspected as viewed by a one-dimensional imaging element, or line scanner, is stored in memory. Data concerning the number of picture elements actually detected in each of the window areas is compared with the stored data and the comparison is stored in memory for use in deciding whether the product inspected is good or bad.
