摘要: A method and apparatus for capturing storing a decodable representation of 1D or 2D bar code symbol using hand-held reader having only image sensor. succession digital representations are produced as the is moved asynchronously across to be read. These examined, substantially in real time, and, if symbol, decoded immediately. If not these examined presence one variety different types finder patterns when has been identified, with reference that pattern.
