METHOD FOR ENCODING ELECTRIC SIGNALS OBTAINED DURING SCANNING OF A GRAPHIC PATTERN HAVING A MIXED CONTENT OF TEXT AND PICTURES

摘要

A method and circuit arrangement for encoding electric signals are provided for the scanning of a graphic pattern having a mixed content of text and pictures, In a first analysis the boundaries of a region are determined, The scanning signals are then subjected to a second analysis to determine the region content. The results of the region analyses are evaluated for determining a code and an accuracy statement. On the basis of the evaluation of all code statements and accuracy statements, one of at least two predetermined codes is selected for encoding the region.
