Abstract: An array of integrated photosensitive devices is used to lift an image of a printed character or symbol from a document or other surface, process the image to allow for background conditions of the document and referencing it against a desired threshold to produce a black/white video output, in serial form, representative of the image sensed by the array. Charge transfer devices are used extensively throughout on a single integrated circuit to provide a complete image processing video device on a single integrated circuit chip.
