ABSTRACT:
A method and circuit for segmentation of characters from a serially-read character sequence scans the character sequence in a column-by-column format and intermediately stores portions or cut-outs of the scanned characters in the form of an image pattern matrix associated with each portion. The image patterns are thus offset by one column with respect to one another. For each image pattern, a coefficient memory stores several coefficients associated to the specific image pattern which are read out and summed to form a margin value which is associated with the average column of the individual image pattern matrix. A maximum value which occurs in the series of continuously formed margin values signifies a separating point for the associated column.
