Abstract

A semi-automatic system for scanning a document includes an image capture device, such as a digital or video camera, which records a sequence of images while a user waves a document in front of the device. The user can present multiple pages of a document to the image capture device, after which the total sequence of images are processed to identify a clear image of each page from the sequence of images. The system further includes image processing techniques to correct for motion blurring, acceleration and perspective errors. The system is capable of processing any size or shape of document without destroying the organization or format of the original.
