ABSTRACT:
A method of effective processing of image information with a limited memory capacity, by dividing elementary picture elements representing image information into unit pixels each containing at least two elementary pictire elements, counting the number of picture elements of a determined density level in each unit pixel and generating a density signal corresponding to the number of thus counted elementary picture elements.
