Abstract
A barcode reading enhancement system includes an attachment for a mobile device, such as a smartphone, tablet, or a hybrid combination thereof, with a camera. The attachment may include an optics system that cooperates with the mobile device camera to facilitate the capture of decodable barcodes. The optics system may increase the camera's depth of field, increase ratio of focal length to entrance pupil diameter, and/or decrease the angular size of the field of view of the camera. The system includes a mobile barcode reading application for setting a camera lens of the camera to one of a plurality of predetermined focus positions or enabling autofocus of the camera within a limited range of focus positions less than a full range of focus positions of the camera. The application may cause the camera to capture an image of a barcode and decode the image of the barcode.
