Abstract
A circuit for adjusting the sensitivity of a sensor which is used typically in document handling equipment is disclosed. A special application of the circuit relates to using a plurality of the sensors in a height-determining operation which is used in conjunction with an imaging device, which scans or images the front, for example, of a document. The height of the particular document being scanned by the imaging device is used to 'scan' only as far as the height of the document so as to eliminate meaningless data from the image of the document.
