Patent ID: 8381984

Claim:
A system for use in reading a bar code symbol disposed on a document; a terminal having an image sensor array comprising a plurality of pixels, the terminal having a lens assembly for use in focusing an image onto the two dimensional image sensor array, and a hand held housing incorporating the image sensor array, wherein the terminal is operative for capture of a frame of image data responsively to an initiation of a trigger signal by an operator, the frame of image data having a representation of the document, and further having a representation of the bar code symbol; a memory; pre-stored information respecting one or more document types stored in the memory, each document type having an associated bar code symbol, the pre-stored information including information respecting a bar code symbol position within a document of a known document type; wherein the system is operative for locating a document feature representation within the representation of the document, the document feature representation corresponding to a document feature other than the bar code symbol; wherein the system is further operative for determining a document type based on the document feature representation; wherein the system is further operative for utilizing the location of the document feature representation determined by the system and the pre-stored information corresponding to the document type to determine the location of a bar code symbol representation in the frame, the bar code symbol representation corresponding to the bar code symbol; and wherein the system is further operative to utilize image data of the determined location of the bar code symbol representation for attempting to decode the bar code symbol.
