Abstract:
1. A scanning device with a positioning sensor, which connected to a computer device, said scanning device comprising: a casing; a linear contact image sensor (CIS), having a signal output; a system processor controls said CIS by a timing signal; a first optical coordinate sensor displacement processor for estimating a first coordinate increment of a real-time displacement of said scanning device; a second optical coordinate sensor and displacement processor for estimating a second coordinate increment of the real-time displacement of said scanning device; an A/D circuit configured to receive the signal output of said CIS, the A/D circuit further configured to output digital image data; a data buffer for storing the first and second coordinate increments and digital image data outputted by the A/D circuit; and wherein said system processor is further configured to packets said first and second displacement coordinate increments stored in said data buffer and the digital image scanning data outputted through said A/D circuit by said linear contact image sensor (CIS), as original scanning data with positioning information, said system processor further configured to transfer the original scanning data with positioning information to the computer device.
