Abstract: A scanner (10;30) is presented that may include a prism shaped, symmetric scanner that can be rotated to enable paper to be fed from the top or the bottom of the scanner. The scanner of the present invention may also include a button (40) to control the direction of the motor so that the user can select to feed paper from either the top for automatic document feed operations or the bottom for single sheet feed operations. These and other advantages are accomplished in a desktop scanner that leverages the desktop real estate, while at the same time provides the scanner flexibility of an automatic document feed scanner.

Abstract: An electrophotographic printer includes a photoreceptor on a drum or belt, a laser beam that is reciprocally scanned thereacross, a beam detect signal circuit for generating a beam detect signal and an asynchronous clock oscillator for generating clock pulses. The printer also includes circuitry for generating a plurality of clock signals that are phase synchronized with the beam detect signal. The circuitry includes a tapped delay line (10) for receiving the asynchronous clock pulses, each tap outputting a delayed clock pulse train. A register/selector (12,14,20,22) circuit is coupled to the taps and is responsive to a transition of the beam detect signal for determining a tap which outputs a 0 DEG phase clock transition that is closely proximate to the beam detect signal. Phase delay logic (42) provides signals indicative of which taps of the delay line circuit (10) manifest clock pulse trains that are closest in time to leading and lagging edges of a 0 DEG phase clock pulse, respectively. The phase delay logic circuit (42) further determines taps of the delay line circuit (10) that are intermediate the aforesaid taps and which of those taps should be utilized to provide delayed clock signals of a fractional phase. Signals from the selected taps are thereafter switched to output circuits.

Abstract: Image sharpening is performed by applying variable contrast stretching to pixels of interest in a digital image. For each pixel of interest, the amount of contrast stretching is a function of minimum and maximum intensity values in a local pixel neighborhood.
