    Abstract: An apparatus for determining a background level of an image to be scanned. The apparatus builds a series of histograms of the image each corresponding to a line of the image, analyzes each of the histograms, and averages the results of the analysis, to continually update a background level during the scan of the image. The apparatus may be implemented with a simple architecture capable of operating at high speed.

    Abstract: A platen cover for an imaging device such as a copier or scanner includes a substrate and at least of portion of the surface of the substrate is coated with a fluorescent coating. Preferably, the substrate has a dark or black color. The dark color of the substrate substantially reduces or eliminates show through of an image on the backside of an original document when the platen cover is not exposed to a light source for imaging. At the same time, when holes or uneven borders are present in the original document, the fluorescent coating fluoresces upon exposure to the light source at these regions of the original document, making these portions appear white in the replicated image and thereby substantially reducing or eliminating the unsightly appearance of these portions as black portions in the replicated image.

    Abstract: The present invention is a method and apparatus to minimize and prevent blooming problems in color image systems. Particular applicability is found where an image on image system is employed. The invention is inserted into the colorant driving signal path of the system. The invention places an averaging circuit in the path of one or more colorant driving signal streams. The averaging circuit produces an average value signal representative of a small area of its respective colorant. A modulator or other signal varying device responsive to the average value signal is placed in the path of yet another but separate colorant driving signal stream. In this manner the separate colorant driving signal is modulated or varied in response to the average neighboring value of a different color thus minimizing and preventing image blooming.

    Abstract: Apparatus for removing residual charged particles from a charge retentive surface characterized by a particle removal roller and a detoning roller, the former of which is adapted to remove the residual particles from the charge retentive surface and the latter of which removes the particles transferred to the particle removal roller. The detoning roller comprises an array of conductive electrodes extending about the circumference thereof such that when a multi-phase power source is applied thereto a travelling electrostatic wave is generated which causes charged particles having a predetermined diameter and charge to be moved axially of the detoning roller towards one end thereof. The particles so moved represent toner devoid of paper debris. Thus they are suitable for reuse.

    Abstract: A method for determining local defocus distance in a scanned image of a non-planar original object is provided comprising scanning at least a portion of the non-planar original object to produce first scanned image data at a first focal plane and scanning same the at least a portion of the non-planar original object to produce at least second scanned image data at a second focal plane. The first scanned image data is different from the second scanned image data wherein a distance between the first focal plane and the second focal plane is a predetermined quantity. The method further comprises estimating an out-of-focus distance of the object from the first and the second scanned image data.
