Barcode-reading system
First Claim
1. A barcode-reading system for a mobile device, the mobile device comprising a camera configured to capture an image of a barcode in a field of view of the camera, a white light source configured to project a field of illumination into the field of view of the camera, a memory, and a processor, the barcode-reading system comprising:
- a barcode-reading enhancement accessory secured to the mobile device, the barcode-reading enhancement accessory comprising an optic system that is positioned within the field of illumination of the white light source, the optic system comprising a dark field illumination system that directs illumination from the white light source into the field of view of the camera at a non-zero angle relative to an optical axis of the camera; and
a barcode-reading application stored in the memory of the mobile device and executable by the processor of the mobile device.

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.

20. A barcode-reading enhancement accessory for a mobile device, the mobile device comprising a camera and a white light source, the barcode-reading enhancement accessory comprising:
-
a dark field illumination system configured to direct illumination from the white light source into a field of view of the camera at a non-zero angle relative to an optical axis of the camera; at least one light pipe within the dark field illumination system, the at least one light pipe being configured to direct the illumination from the white light source to a periphery of the field of view of the camera; and at least one prism optic that redirects the illumination from the white light source into the field of view of the camera at the non-zero angle relative to the optical axis of the camera.
