Methods and apparatus for identifying candidate barcode fields
First Claim
1. A method for decoding a desired barcode affixed to an item having a plurality of barcodes provided thereon, said method comprising the steps of:
- acquiring, via a barcode imager, an image of the item within a field of view of said barcode imager;
analyzing said acquired image to determine a set of potential barcode fields;
determining, using a predetermined criterion, a candidate barcode field from among said set of potential barcode fields;
displaying a modified image derived from said acquired image, wherein said candidate barcode field is identified within said modified image; and
allowing a user to initiate a decode session when said candidate barcode field includes the desired barcode.

Abstract
A system is provided for selecting a particular barcode on an item that includes multiple barcodes. The system (1) acquires, via a barcode imager, an image of the item within the field of view of the barcode imager, (2) analyzes the acquired image to determine a set of potential barcode fields, (3) determines, using a predetermined criterion (e.g., distance from center of imaged area, type of bar code, etc.), a candidate barcode field from among the set of potential barcode fields, (4) displays a modified image derived from the acquired image, wherein the candidate barcode field is identified within the modified image, and (5) allows the user to initiate a decode session when the candidate barcode field includes the desired barcode. The acquired may be modified to highlight the candidate barcode field in any number of ways, including, for example, superimposing an artificial reticule around the candidate field, superimposing an artificial scan line over the field, altering the contrast of the field, and/or altering the brightness of the field.

8. A barcode imaging system comprising:
-
a barcode imager configured to acquire an image of an item within a field of view of said barcode imager and to allow a user to initiate a decode session; a processor communicatively coupled to the barcode imager, said processor configured to;
analyze said acquired image to determine a set of potential barcode fields;determine, using a predetermined criterion, a candidate barcode field from among said set of potential barcode fields; and a display communicatively coupled to said processor, said display configured to display a modified image derived from said acquired image, wherein said candidate barcode field is identified within said modified image. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)
