Abstract
A method of operating a bar code scanning system adapted for assembling information bearing indicia (IBI) information from partial scans of IBI data which may comprise some undecodable characters, the method comprising the steps of: converting light reflected from a target into output signals representative thereof utilizing an image sensor; illuminating the target utilizing an illumination source; directing light from the target to the image sensor array utilizing receive optics; determining if information contained in IBI within the target derived from the output signals is not decodable; transmitting an image of the IBI to a host processor if the IBI is not decoded.
