Barcode reading system for a mobile device with a barcode reading enhancement accessory and barcode reading application
First Claim
1. A barcode reading system fora mobile device, the mobile device comprising a camera having a field of view to a back side of the mobile device, a white light source for projecting a field of illumination towards the back side of the mobile device, a memory and a processor, and the barcode reading system comprising:
- a barcode reading enhancement accessory secured to the mobile device, the barcode reading enhancement accessory comprising an optic system, the optic system comprising;
a reflective surface for folding the field of view of the camera towards a target area positioned at a top side of the mobile device;
a reflective surface for folding the field of illumination of the white light source towards the target area; and
a target-generating structure configured to narrow the field of illumination of the white light source along a first direction such that the field of illumination of the white light source in the first direction has a divergence angle that is approximately the same as a divergence angle of the field of view of the camera in the first direction; and
a barcode reading application stored in the memory and executable by the processor, the barcode reading application including;
an image capture function for controlling the white light source and the camera to capture an image of a barcode in the target area;
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
Described herein is a barcode-reading system for a mobile device that may include an optic system with a reflective surface for folding a field of view of a camera of the mobile device towards a target area positioned at a top side of the mobile device, a reflective surface for folding a field of illumination of a white light source of the mobile device towards the target area, and a target-generating mechanism for narrowing the field of illumination of the white light source along a first direction such that the field of illumination of the white light source has a divergence angle in the first direction that is approximately the same as a divergence angle of the field of view of the camera in the first direction.

8. A method of reading a barcode utilizing a mobile device, the mobile device comprising a camera having a field of view to a back side of the mobile device, a white light source for projecting a field of illumination towards the back side of the mobile device, a memory and a processor, and the method comprising:
-
directing an operating system of the mobile device to obtain a barcode reading application from a remote application server and to install the barcode reading application in the memory for execution by the processor; securing a barcode reading enhancement accessory to the mobile device, the barcode reading enhancement accessory comprising an optic system, the optic system comprising; a reflective surface for folding the field of view of the camera towards a target area positioned at a top side of the mobile device and a reflective surface for folding the field of illumination of the white light source towards the target area; and a target-generating structure configured to narrow the field of illumination of the white light source along a first direction such that the field of illumination of the white light source has a divergence angle in the first direction that is approximately the same as a divergence angle of the field of view of the camera in the first direction; and executing the barcode reading application by the processor, execution of the barcode reading application comprising; execution of an image capture function to control the white light source and the camera to capture an image of the barcode in the target area; execution of a decoder function to generate decoded data representing data encoded in the barcode; and execution of a relay function to send the decoded data to a server via a wireless connection established between the mobile device and a network. - View Dependent Claims (9, 10, 11, 12, 13, 14)
