Text document capture with jittered digital camera
Abstract:
A digital imaging device such as a digital camera is used to obtain multiple digital images of all of a text document segment. The text document segment could be the entire text document so that each digital image would be of the entire text document. The multiple images are obtained while lateral jittering is imparted between the digital imaging device and the text document. The lateral jittering may be in a pair of transverse (e.g., perpendicular) directions. An enhanced resolution representation of the text document is formed from the multiple laterally displaced images and de-blurred as a multi-frame reconstruction.
