Systems and Methods for Efficiently Capturing High-Quality Scans of Multi-Page Documents with Hand-Held Devices
First Claim
1. A method of capturing a sequence of images of a multi-page printed document, performed by a handheld device with one or more processors, memory, and a digital image sensor, the method comprising:
- monitoring preview images of a first printed page of the multi-page printed document, the preview images generated by the digital image sensor;
without user indication of when to capture an image, capturing a still image of the first printed page when a first quality metric of the preview images exceeds a first quality threshold;
repeating the monitoring and capturing of additional pages of the multi-page printed document until receiving indication from the user that capturing images is complete; and
in response to receiving indication from the user that capturing images is complete;
concatenating the captured still images into a single digital document; and
storing the single digital document.

Abstract
Capturing a sequence of images of a multi-page printed document is performed by a handheld device, such as a Smartphone. The device has one or more processors, memory, and a digital image sensor. The device monitors preview images of a first printed page of the multi-page printed document, where the preview images are generated by the digital image sensor. Without user indication of when to capture an image, the device captures a still image of the first printed page when a first quality metric of the preview images exceeds a first quality threshold. The device repeats the monitoring and capturing of additional pages until receiving indication from the user that capturing images is complete. In response to receiving indication from the user that capturing images is complete, the device concatenates the captured still images into a single digital document and stores the single digital document.

16. A system for capturing a sequence of images of a multi-page printed document, comprising:
-
one or more processors; memory; and one or more programs stored in the memory, the one or more programs comprising instructions for; monitoring preview images of a first printed page of the multi-page printed document, the preview images generated by the digital image sensor; capturing a still image of the first printed page when a first quality metric of the preview images exceeds a first quality threshold, executed without user indication of when to capture the still image; repeating the monitoring and capturing of additional pages of the multi-page printed document until receiving indication from the user that capturing images is complete; and responding to receiving indication from the user that capturing images is complete, including instructions for; concatenating the captured still images into a single digital document; and storing the single digital document.

17. A computer readable storage medium storing one or more programs configured for execution by a computer, the one or more programs comprising instructions for:
-
monitoring preview images of a first printed page of the multi-page printed document, the preview images generated by the digital image sensor; capturing a still image of the first printed page when a first quality metric of the preview images exceeds a first quality threshold, executed without user indication of when to capture the still image; repeating the monitoring and capturing of additional pages of the multi-page printed document until receiving indication from the user that capturing images is complete; and responding to receiving indication from the user that capturing images is complete, including instructions for; concatenating the captured still images into a single digital document; and storing the single digital document.
