Integral computer scanning system

摘要: A photovoltaic film provided with a computer allows the to be used as scanner well conventional computer. In preferred embodiment is transparent, and applied directly display screen of system. The connected signal processing means internal bus structure hard copy document positioned adjacent film, control routines loaded run on pixel illumination in scanning protocol. Illumination pixels conjunction characteristics at position cause generated by alter voltage. Signals from are processed generate bit pattern scanned image. an alternative part separate sheet applicable connectable expansion card for connection computer, providing system useful existing computers.
