ABSTRACT:
A bilevel original is read in the form of multi-gradation image data stored as 3 by 3 pixels in a latch circuit. An ROM stores data of bilevel image patterns higher in resolution than the multi-gradation image data. The stored data are related to every combination of gradation values of a central pixel in 3 by 3 image regions and data patterns of peripheral pixels thereof. The image data stored in the latch circuit are supplied as an address input to the ROM, which in turn outputs corresponding high-resolution bilevel image pattern data.
