A specially designed input workstation is required to convert documents or images to machine-readable form for computer processing and storage. At a minimum, the input workstation includes a document scanner, an image processor unit, a video display unit, keyboard, and access to storage. Using a solid-state array or other photo-sensitive components, the document scanner measures the amount of light associated with successively encountered PELs (Picture ELement) and transmits a corresponding electrical signal that is converted to computer compatible digital codes.
