Barcode-reading enhancement system for a computing device that comprises a camera and an illumination system
First Claim
1. A barcode reading enhancement system for a mobile device, the mobile device being selected from the group consisting of smartphones, tablets, and combinations thereof, the mobile device comprising a processor, a display screen, memory, an illumination torch, and a camera comprising a camera lens and an image sensor, the barcode reading enhancement system comprising:
- an optic system aligning with the camera lens to define a barcode reading lens system, the barcode reading lens system being defined by a combination of the camera lens and the optic system, the barcode reading lens system providing a system field of view which is different from a camera field of view of the camera lens; and
an illumination optic system aligning with the illumination torch of the mobile device to define an exposure illumination system, wherein the illumination optic system comprises an illumination lens that is positioned within a torch illumination field of the illumination torch, and wherein the illumination lens modifies the torch illumination field such that the exposure illumination system emits a system illumination field with a system angular size that is different from a torch angular size of the torch illumination field emitted by the illumination torch;
wherein the system field of view and the system illumination field substantially overlap;
wherein the optic system is housed in a first chamber of an attachment securable to an external surface of the mobile device; and
wherein the illumination optic system is housed in a second chamber of the attachment, the second chamber being optically isolated from the first chamber to prevent illumination from the illumination torch from entering the camera without first reflecting from an object within the system field of view.

Abstract
A barcode reading enhancement system for a mobile device may include an optic system aligning with a camera lens of the mobile device to define a barcode reading lens system. The barcode reading lens system may be defined by a combination of the camera lens and the optic system. The barcode reading lens system may provide a system field of view that is different from a camera field of view of the camera lens. The barcode reading enhancement system may also include an illumination optic system aligning with an illumination torch of the mobile device to define an exposure illumination system. The exposure illumination system may emit a system illumination field with a system angular size that is different from a torch angular size of a torch illumination field emitted by the illumination torch. The system field of view and the system illumination field may substantially overlap.

7. A barcode reading enhancement system for a mobile device, the mobile device being selected from the group consisting of smartphones, tablets, and combinations thereof, the mobile device comprising a processor, a display screen, an illumination torch, a camera, and memory, the camera comprising a camera lens positioned parallel to a back surface of the mobile device and having a camera field of view extending orthogonally from the back surface, the back surface being opposite the display screen on a face surface of the mobile device, the barcode reading enhancement system comprising:
-
an optic system aligning with the camera lens to define a barcode reading lens system, the barcode reading lens system being defined by a combination of the camera lens and the optic system, the barcode reading lens system providing a system field of view which is different in both angular size and optical pathway direction from the camera field of view; and an illumination optic system aligning with the illumination torch of the mobile device to define an exposure illumination system, wherein the illumination optic system comprises an illumination lens that is positioned within a torch illumination field of the illumination torch, and wherein the illumination lens modifies the torch illumination field such that the exposure illumination system emits a system illumination field with a system angular size that is different from a torch angular size of the torch illumination field emitted by the illumination torch; wherein the system illumination field is directed into the system field of view; wherein the optic system is housed in a first chamber of an attachment securable to an external surface of the mobile device; and wherein the illumination optic system is housed in a second chamber of the attachment, the second chamber being optically isolated from the first chamber to prevent illumination from the illumination torch from entering the camera without first reflecting from an object within the system field of view. - View Dependent Claims (8, 9, 10, 11, 12)
