Document decoding system and method for improved decoding performance of indicia reading terminal

A system for reading a bar code symbol disposed on a substrate, said system comprising:

• an indicia reading terminal comprising a two dimensional image sensor array comprising a plurality of pixels extending along an image plane, an optical assembly for use in focusing imaging light rays onto the plurality of pixels of said two dimensional image sensor array, and a housing encapsulating the two dimensional image sensor array and the optical assembly;
• an external server in communication with the indicia reading terminal, the external server external to the indicia reading terminal,
• wherein the system is operative in a mode in which the terminal, in response to an operator initiated command, captures a frame of image data and processes the frame of image data for attempting to decode the decodable indicia,
• wherein the system in the mode is operative to populate records in a data table with information respecting one or more characteristics of the document,
• wherein the characteristics of the document comprise positional location data of the decodable indicia relative to a document field within a frame of image data,
• wherein the system in the mode is operatively responsive to the records to reduce a decode time that defines the difference in a first decode time for a first document and a second decode time for a second document, and
• wherein the first document and the second document have the same document characteristic.

A method for improving processing time of document image data captured with an indicia reading terminal, the document image data corresponding to a document with a decodable indicia, said method comprising:

• receiving an operator initiated command for capturing a frame of image data and processing the frame of image data for attempting to decode the decodable indicia;
• defining a document field within the frame of image data;
• accessing a data table comprising at least one recording having information respecting a characteristic of the document so imaged;
• and
• attempting to decode the decodable indicia,
• wherein the characteristic of the document comprises at least positional location data of the decodable indicia relative to the document field,
• wherein the records reduce a decode time that defines the difference in a first decode time for a first document and a second decode time for a second document, and
• wherein the first document and the second document have the same document characteristic.
