Abstract
Real-time evaluation of high quality preview images of a document prior to capturing a final image of the document on a mobile device is disclosed. In one aspect, an image capture device is activated on the mobile device. A plurality of preview images of the document is then captured, each of which has a lower image quality than a final image to be captured by the image capture device. Next, for each of the plurality of preview images, the system measures a parameter associated with the image capturing, and related to the ability to accurately extract text and other content from a captured preview image of the document. Next, the system selects a preview image among a subset of the captured preview images that passes the image quality measurement. When a predetermined condition is met, the system chooses the selected preview image as a final captured image of the document.
