Abstract

A mobile device includes a camera, a user interface system, and a processor communicatively coupled to the camera and the user interface system. The user interface system includes a visual display. The processor is configured for (i) capturing an image including a code symbol, (ii) displaying the image on the visual display, (iii) determining whether the code symbol in the image is readable by the processor, and (iv) displaying on the visual display a positive indicator overlaying the code symbol in the image when the processor determines that the code symbol in the image is readable by the processor. The processor is further configured for reading the code symbol in the image in response to a selection input received from the user interface system.

Claims

1. A mobile device, comprising:

a camera;

a user interface system comprising a visual display; and

a processor communicatively coupled to the camera and the user interface system, the processor being configured for;

capturing from the camera an image depicting a code symbol;

displaying the image on the visual display;

determining whether the code symbol in the image is readable by the processor; and

displaying on the visual display a positive indicator overlaying the code symbol in the image when the processor determines that the code symbol in the image is readable by the processor.

2. The mobile device of claim 1, wherein the processor is configured for:

reading the code symbol in the image in response to a selection input received from the user interface system.

3. The mobile device of claim 2, wherein the visual display comprises a touchscreen and the selection input is initiated by a user'"'"'s tactile command selection of the code symbol in the image appearing on the touchscreen.

4. The mobile device of claim 3, wherein the tactile command comprises touching the code symbol on the display screen with the user'"'"'s finger.

5. The mobile device of claim 3, wherein the tactile command comprises touching the code symbol on the display screen with a stylus.

6. The mobile device of claim 3, wherein the tactile command comprises pointing at the code symbol on the display screen.

7. The mobile device of claim 3, wherein the tactile command comprises looking at the code symbol on the display screen for a predetermined period of time.

8. The mobile device of claim 1, wherein the code symbol comprises a barcode symbol.

9. The mobile device of claim 1, wherein the positive indicator comprises a circle.

10. The mobile device of claim 1, wherein the positive indicator comprises a line drawn substantially along the perimeter of said code symbol.

11. The mobile device of claim 1, wherein the positive indicator comprises a color highlight of the code symbol.

12. The mobile device of claim 1, wherein the processor is configured for displaying on the visual display a negative indicator overlaying the code symbol in the image when the processor determines that the code symbol in the image is not readable by the processor.

13. A method of reading a code symbol with a mobile device, comprising:

providing a mobile device having a camera, a user interface system having a visual display, and a processor communicatively coupled to the camera and the user interface system;

capturing with the camera an image including a code symbol;

displaying the image on the visual display;

determining with the processor whether the code symbol is readable by the processor;

displaying on the visual display a positive indicator overlaying the code symbol when the processor determines that the code symbol is readable by the processor.

14. The method of claim 13, comprising:

reading the code symbol with the processor in response to a selection input from the user interface system.

15. The method of claim 14, wherein the visual display comprises a touchscreen and the selection input is initiated by a user'"'"'s tactile command selecting the code symbol in the image appearing on the touchscreen.

16. The method of claim 13, comprising:

displaying on the visual display a negative indicator overlaying the code symbol when the processor determines that the code symbol is not readable by the processor.

17. The method of claim 13, wherein the code symbol comprises a barcode symbol.

18. The method of claim 13, wherein the positive indicator comprises a circle.

19. The method of claim 13, wherein the positive indicator comprises a line drawn substantially along the perimeter of the code symbol.

20. The method of claim 13, wherein the positive indicator comprises a color highlight of the code symbol.
