Abstract
A facsimile image coding method in which a pattern appearing only once in the input image is encoded by the conventional facsimile coding method which sequentially scans the input image as a graphic element thereon for encoding, and a pattern appearing twice or more is encoded by encoding the positional coorinates and the identification code added at the time of registration in the pattern library as in the case of the pattern matching method. As a result of the above operations of the present invention, a high compression ratio, not only for a printed document but also for handwritten and graphic documents, is obtained.
