Backlit display detection and radio signature recognition
First Claim
1. A method of capturing an image of a barcode from a backlit display device, the method comprising:
- monitoring and measuring proximal radio signals with a barcode scanner;
detecting, with the barcode scanner, radio interference produced by a backlit display device;
interpreting a signal pattern of the detected radio interference, and correlating the pattern to one or more technical characteristics of the backlit display device;
using the determined technical characteristics of the backlit display device for automatically selecting one or more scanning settings on the barcode scanner;
detecting a displayed image of a barcode on the backlit display device, with the barcode scanner; and
capturing the detected displayed image with a capturing system disposed within the barcode scanner.

Abstract
A method of capturing an image of a barcode from a backlit display device includes monitoring radio signals proximal to a device operable for scanning barcodes, with at least one coil, wire, and/or antenna disposed within the device operable for scanning barcodes; detecting radio interference caused by a backlit display device proximal to the device operable for scanning barcodes; interpreting a pattern of the radio interference to determine one or more technical characteristics of the backlit display device; using the determined technical characteristics of the backlit display device for automatically adjusting scanning settings of the device operable for scanning barcodes; and capturing an image of a barcode displayed on the backlit display device.

5. A method of communicating information displayed on a mobile device, the method comprising:
-
determining, with an interfacing device having a code-reading terminal, a type of a mobile device based on emitted radio signals; adjusting one or more scanning parameters to preselected values based on the determined type of the mobile device; and capturing an image of a computer-readable code displayed on the mobile device placed in front of the code-reading terminal of the interfacing device. - View Dependent Claims (6, 7, 8, 9, 10)

11. A method of scanning a barcode from a digital device, the method comprising:
-
monitoring radio signals proximal to a device operable for scanning barcodes, with at least one coil, wire, and/or antenna disposed within the device operable for scanning barcodes; detecting radio interference produced by a digital device proximal to the device operable for scanning barcodes; coupling and amplifying the detected radio interference signals with the at least one coil, wire, and/or antenna; adjusting one or more scanning parameters based on a pattern of the detected radio interference; and capturing an image of a barcode displayed on the digital device. - View Dependent Claims (12, 13, 14, 15)
