Abstract

A system and method for obtaining selected image information from a digital image and providing that selected image information for selective handling. In one aspect, the present invention automatically locates and segments an item identifier from an image caught by a digital camera and provides image information related to the item identifier for processing. Alternatively, a user can designate what areas of an image comprise the item identifier of interest for further viewing or processing.

Claims

1. A method for handling an image of an image subject at a digital image capture camera device comprising the steps of:

capturing an image comprising image information and at least one randomly located item identifier embodying information about the image subject of the image information;

automatically analyzing the image to locate the at least one item identifier in a randomly located area of interest of the captured image based on the contents of the area of interest; and

selectively processing said at least one item identifier.

2. The method of claim 1 wherein said locating further comprises extracting at least one item identifier from said image.

3. The method of claim 1 wherein said at least one item identifier comprises barcode information.

4. The method of claim 3 wherein said selective processing comprises decoding said barcode information.

5. The method of claim 3 wherein said locating further comprises determining the dominant orientation of said barcode information.

6. The method of claim 3 wherein said locating further comprises extracting edges from said image to locate said barcode information.

7. The method of claim 1 further comprising segmenting said item identifier from said image.

8. The method of claim 7 wherein said segmenting comprises segmenting said item identifier from said image.

9. The method of claim 7 further comprising discarding nonsegmented information from said image.

10. The method of claim 2 wherein said selective processing comprises transmitting said item identifier to a remote location.

11. The method of claim 1 wherein said selective processing comprises determining the coordinates of said item identifier.

12. The method of claim 11 wherein said selective processing further comprises transmitting said coordinates to a remote location.

13. The method of claim 2 wherein said selective processing comprises selectively compressing said at least one item identifier.

14. The method of claim 13 further comprising transmitting said selectively compressed at least one item identifier.

15. The method of claim 1 wherein said selective processing comprises creating metadata about said at least one item identifier.

16. The method of claim 15 wherein said selective processing further comprises associating said metadata with said at least one item identifier.

17. The method of claim 16 wherein said selective processing further comprises transmitting at least one of said metadata and said at least one item identifier to a remote location.

18. A system for handling a digital image of an image subject comprising:

an image capture camera device for capturing a digital image, said digital image comprising image information and at least one randomly located item identifier embodying information about the image subject of the image information; and

a processing Component comprising;

an item identifier locating component for automatically analyzing the image to determine the location of said at least one item identifier in a randomly located area of interest of the captured image based on the contents of the area of interest; and

at least one item identifier processing component for determining at least one of a plurality of processes for selectively processing said at least one item identifier.

19. The system of claim 18 wherein said at least one item identifier processing component comprises a transmitter for transmitting said at least one item identifier to a remote location.

20. The system of claim 18 wherein said at least one item identifier processing component comprises compression means for compressing said at least one item identifier for transmission.

21. The system of claim 18 wherein said at least one item identifier processing component comprises a metadata creating component for creating metadata for said at least one item identifier.

22. A digital camera for handling a digital image of an image subject comprising:

an image capture device for capturing a digital image of an image subject, said digital image comprising image information and at least one randomly located item identifier embodying information about the image subject of the image information; and

a processing component comprising;

an item identifier locating component for automatically analyzing the image to determine the location of said at least one item identifier in a randomly located area of interest of the captured image based on the contents of the area of interest; and

at least one item identifier processing component for selectively processing said at least one item identifier.
