摘要:
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.
