    Abstract: A scanner frame (20) comprises a vertical track (22) which is slidably attached at one end thereof to a horizontal track (24). The horizontal track is attached to a drawing board (28) or any other suitable flat surface. An optical imaging device (36) (i.e., an optical scanner) is slidably attached to the vertical track. A marker strip (37) comprising a series of bars (38) of uniform pitch are disposed on a surface of the horizontal track along the length thereof. These bars are detected by a sensor assembly (40) disposed on the vertical track. Another marker strip (41) comprising a series of bars (42) of uniform pitch are disposed on a surface of the vertical track along the length thereof. These bars are detected by a sensor assembly (44) disposed on the scanner.

    Abstract: A multiple camera automatic digitizer includes a plurality of spaced video cameras (19) mounted within a housing (3) under a transparent digitizing surface (51). Multiplexing circuitry (37) multiplexes video signals from a selected video camera into a video amplifier (51), the output of which is converted to a digital number representing the darkness of the point of the document most recently scanned by a presently selected one of the video cameras. In accordance with the invention, the automatic digitizer includes a microprocessor (111), system controls that allows selection of various ones of the video cameras to achieve digitizing of corresponding areas of a large document, and computes skew correction factors for each camera as the basis of digitizing of a plurality of permanent alignment marks (P) on a bottom surface of a cover (11) for the digitizing surface. The skew correction factors are used to skew correct the camera data produced by the corresponding camera. The skew corrected lateral offset of each camera is computed by the microprocessor on the basis of the digitized coordinates of the alignment points and is used to automatically compute skew corrected, offset corrected document coordinates for all of the video cameras.

    Abstract: An image processing apparatus for correcting a dislocation of image, pixels being arranged in a first and second directions perpendicular to each other, including: a section which breaks down a correction amount of the image of each pixel in the second direction into a first shift amount with a unit of a prescribed block, a second shift amount with a unit of the pixel, and a third shift amount less than the pixel size; a minimal shift section which shifts the image data by the third shift amount; a pixel unit shift section which shifts the image data by the second shift amount; and a block unit shift section which shifts the image data by the first shift amount, during compression and storage processing of the image data in the block unit, and executing arrangement of the image data after reading-out and expanding the compressed image data.
