Abstract
An apparatus for producing a code word indicative of vertical correlations in color changes between scanned lines of an information bearing document. The apparatus comprises a memory and counter for storing and retrieving the color of picture elements in the prior scanned line from which correlation is determined. The apparatus further comprises a state machine which may produce an intermediate code word from data corresponding to only part of the picture elements being correlated and which remembers the data from other picture elements by moving from state to state.
