Abstract
A method of encoding information from a scanned original, for example in the production of halftone pictures by producing a video signal indicative of the original information, comparing it with a screen dot pattern to produce a series of signals which may have weighted values for separate sub areas within the screen dot area to form values representing the information for each of the original sub areas and combining the weighted values according to a predetermined function so that an encoded signal is produced indicative of the modulated distribution of the information of the sub areas of the pattern.
