摘要：
The present invention discloses a system for processing data from scanned documents. The output from a scanner serves as input to a digital filter referred to as an event driven interface. The event driven interface is user-configured with bit patterns to identify and filter out user-designated information from a scanned document. Since only the designated information is extracted from the document, and not extraneous matter of the document, the subsequent storage of only the designated information saves computer memory. Furthermore, the designated information can be transmitted over a data communications network. Such a transmission will occupy less bandwidth than if the entire document was transmitted.
