A portable raster input scanner for electronically reading a document image and storing the resultant video information with or without audio comment on magnetic tape, such as a video cassette, may be desirable. For this purpose, a vidicon may be contemplated as the scanner since devices of this type can generally be made highly portable, have modest illumination requirements (equal or close to typical offie levels), are silent in operation and draw relatively small amounts of electrical power (typically, 100 watts). Furthermore, vidicon technology has been conveniently interfaced with low-cost video tape recording hardware for some years. It appears that the only factor precluding the use of vidicons from document raster scanning applications is the vidicon's limited resolution.
