Abstract

In some embodiments, provided are methods and reading devices with image capture capabilities for efficiently capturing multiple images.

Claims

1. An apparatus, comprising:

a reading device with logic configured to cause the reading device to;

monitor an image area for an image;

determine whether the image is different from a previous image in the image area; and

cause the image to be captured based at least in part on a result of determination whether the image is different from the previous image.

2. The apparatus of claim 1, wherein the logic is configured to cause the reading device to determine whether the image is different through determination of whether the image has sufficiently different content from the previous image.

3. The apparatus of claim 2, wherein determination of whether the image has sufficiently different content from the previous image comprises determination of whether the image has a page number that is in a proper sequence relative to the previous image.

4. The apparatus of claim 3, wherein determination of whether the image has sufficiently different content from the previous image further comprises determination, in response to a user override, that the image has sufficiently different content regardless of whether the page number is in a proper sequence.

5. An apparatus, comprising:

a reading device with logic configured to cause the reading device to;

monitor an image area for an image;

determine if the image is ready to be captured; and

cause the image to be captured based at least in part on a result of a determination of whether appropriate motion has occurred above the image area.

6. The apparatus of claim 5, in which the appropriate motion comprises a user'"'"'s hand gesture.

7. The apparatus of claim 5, wherein the logic is further configured to cause the reading device to wait a period of time from the determination that appropriate motion has occurred until capturing the image.

8. The apparatus of claim 7, in which the period of time is set by the user.

9. The apparatus of claim 7, in which the period of time is determined by the reader device.

10. A method, comprising:

monitoring, by a reading device, an image area for an image;

determining, by the reading device, whether the image is different from a previous image in the image area; and

causing, by the reading device, the image to be captured based at least in part on a result of determination whether the image is different from the previous image.

11. The method of claim 10, in which determining if the image is different from the previous image comprises determining whether the image has sufficiently different content from the previous image.

12. The method of claim 11, in which determining if the image has sufficiently different content comprises determining whether the image has a page number that is in a proper sequence relative to the previous image.

13. The method of claim 12, wherein determining whether the image has sufficiently different content from the previous image further comprises determining, in response to a user override, that the image has sufficiently different content regardless of whether the page number is not in a proper sequence.

14. A method, comprising:

monitoring, by a reading device, an image area for an image;

determining, by the reading device, whether the image is different from a previous image in the image area; and

causing, by the reading device, the image to be captured based at least in part on a result of determination of whether appropriate motion has occurred above the image area.

15. The method of claim 14, in which the appropriate motion comprises a user'"'"'s hand gesture.

16. The method of claim 14, further comprising waiting, by the reading device, a period of time from the determination that appropriate motion has occurred until capturing the image.

17. The method of claim 16, in which the period of time is set by the user.

18. The method of claim 16, in which the period of time is determined by the reader device.
