Abstract
A scanning system includes a scanner accessory which is operationally supported by a wider-purpose wireless handheld communications device. The communications device may be a personal digital assistant (PDA), a cellular phone, a combined PDA/cellular phone, or a similar device that enables wireless communications. The scanner accessory is adapted for freehand scanning and includes an image sensor, at least one navigator, and data transfer circuitry that is compatible with exchanging information with the communications device, including outgoing captured image information and incoming scan control information for controlling scanning operations by the scan accessory. Simultaneous with capturing image information by the image sensor, the navigator tracks the position of the image sensor relative to a document being scanned, so that the image information can be 'position-tagged' to form an electronic image for display at the communications device. Alternatively, the scanning capability can be integrated into the wireless handheld communications device.
