H04N1/4057 - CPC Classification

Classification description:

Scanning, transmission or reproduction of documents or the like, e.g. facsimile transmission; Details thereof; Picture signal circuits; Halftoning, i.e. converting the picture signal of a continuous-tone original into a corresponding signal showing only two levels producing a clustered dots or a size modulated halftone pattern the pattern being a mixture of differently sized sub-patterns, e.g. spots having only a few different diameters
