Barcode-reading system
First Claim
1. A barcode-reading system for a mobile device, the mobile device comprising a camera for capturing an image of a barcode in a field of view of the camera, the barcode-reading system comprising:
- a barcode-reading enhancement accessory secured to the mobile device, the barcode-reading enhancement accessory comprising at least one optic system, the at least one optic system comprising;
a dark field illumination system comprising at least one dark field illuminator powered by a battery within the barcode-reading enhancement accessory and directing illumination into the field of view of the camera at an angle greater than 45 degrees from an optical axis of the camera; and
a barcode-reading application stored in a memory of the mobile device and executable by a processor of the mobile device, the barcode-reading application including;
an image capture function for controlling the dark field illuminator through a communication interface between the mobile device and the barcode-reading enhancement accessory and controlling the camera to capture an image of a barcode, the image of the barcode being affected by the at least one optic system;
a decoder function for receiving the image of the barcode and generating decoded data representing data encoded in the barcode; and
a relay function for sending the decoded data to a remote server via a wireless connection established between the mobile device and a network.

Abstract
This patent specification describes a barcode-reading enhancement accessory for a mobile device having a barcode-reading capability. The accessory may include an outer case and an inner carriage. A mobile device is encased in the inner carriage, and the combination of the inner carriage and the mobile device may be accommodated in the outer case. The inner carriage is configured to accommodate a mobile device of a particular size such that a mobile device of a different size may be accommodated in the outer case using a different inner carriage. The accessory may also include an optic system to fold an optical path of a field of illumination of a light source of the mobile device and/or a field of view of a camera of the mobile device.
