Signature capture using electro-optical scanning |
摘要 |
Two-dimensional information such as a written signature can be captured and subsequently reconstructed by using an electro-optical scanner. A multi-row preamble code and a multi-row postamble code flank the signature, and each code has a row identifier for identifying which row is being scanned by a scan line emitted by the scanner, as well as start/stop data for identifying when each scan line traverses the boundaries of a space containing the signature.
