System and method for document processing
First Claim
1. A system for processing a document 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,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 a form barcode on the document,wherein the system is further operative to identify a coordinate system on an image plane from information stored in the form barcode, wherein the system is yet further operative to identify relative to the form barcode and in the coordinate system the position of a content field located on the document,wherein processing of the frame of image data on a first document having the form barcode disposed thereon is faster than processing of the frame of image data on a second document without the form barcode;
- wherein the system is operative to identify at least one corner of the form barcode; and
wherein the coordinate system is located relative to the identified corner.

Abstract
Embodiments of the present invention are directed to document processing, and more particularly to systems and methods that can utilize relative positions between the content of the document and a decodable indicia affixed to the document. In one embodiment, indicia reading terminals are provided that include an imaging module for capturing a frame of image data of a document. The document can include one or more decodable indicia such as a form barcode and various content fields, which delineate particular content of the document. The form barcode can include information respecting the form design and form design data. This information can be used to process the content of the document such as by providing coordinates or similar location and positioning metrics for use in processing the content of the document. In one example, the frame of image data is analyzed to identify the form barcode, from which the relative location of the content fields can be discerned without extensive processing of the frame of image data.

8. A system for automatedly handling documents, 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 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 a form barcode on the document, wherein the system is operative to form an image plan on which is located a grid respecting a coordinate system, wherein the grid has grid points established from at least one corner of the form barcode, wherein the system is further operative to identify on the grid a content field with coordinates in the coordinate system that correspond to information encoded in the form barcode, and wherein processing of the frame of image data on a first document having the form barcode disposed thereon is faster than processing of the frame of image data on a second document without the form barcode.

9. A method of processing a document comprising:
-
capturing a frame of image data corresponding to the document; processing the frame of image data to locate a form barcode affixed to the document; establishing a coordinate system on an image plane respecting the captured image data; locating relative to the form barcode and on the coordinate system a content field on the document; and locating at least one corner of the form barcode; wherein processing of the frame of image data on a first document having the form barcode disposed thereon is faster than processing of the frame of image data on a second document without the form barcode; and wherein the coordinate system is established relative to the at least one corner. - View Dependent Claims (10, 11, 12, 13, 16, 17, 18)
