1. A system for use in decoding a decodable indicia on a document, 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; and

    a memory in communication with the indicia reading terminal, the memory having a zone for storing a data table comprising at least one record;

    wherein the system is operative in a mode in which the system, 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 the records in the 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, andwherein the first document and the second document have the same document characteristic.
