Abstract: In a method for engraving printing cylinders for rotogravure in an electronic engraving machine, at least two engraving lanes with predetermined lane widths lying side-by-side in an axial direction of the printing cylinder are engraved with a respectively allocated engraving element. Before the engraving, an axial reference position is predetermined for each engraving element, the axial spacings thereof relative to one another corresponding to the predetermined lane widths of the engraving lanes. The engraving elements are roughly positioned to their reference positions. Subsequently, the axial spacing errors between the reference positions and the actual position of the engraving element the rough positions are measured. During engraving, the engraving elements are moved along the printing cylinder with the faulty spacings relative to one another caused by their rough positioning. The spacing errors are compensated by a shifted engraving of the engraving lanes on the printing cylinder such that the engraving lanes exhibit the predetermined lane widths despite the incorrect spacings of the engraving elements relative to one another.

Abstract: A method of reconstructing an image captured as a stream of image data, for example as input received from a linear sensor in unconstrained scanning, comprises reconstructing the image in the form of a plurality of tiles. Each tile comprises a pixel grid of predetermined dimension representing a specific spatial region of the image. The tiles tessellate a rectilinear image space. Tiles can be created when required and compressed when no longer active, thus minimizing memory requirements. Devices utilizing this method are provided. The method is especially appropriate for use in an unconstrained hand scanner, but can also be applied to panoramic capture with a digital camera.

Abstract: A light scanning device deflects a plurality of light beams by a deflecting means performs divided scanning on a single scanning line on a photoconductor with the plurality of deflected light beams. When the scanning line is scanned, a detecting means detects a light beam passing through a predetermined position in front of a position where the light beam first strikes an image forming range on the photoconductor. An oscillating means oscillates a specified number of clocks in a time interval from when the light beam is detected by the detecting means until it is detected thereby again. An adjusting means makes adjustments so as to irradiate a plurality of light beams based on clocks oscillated by the oscillating means. In a time interval after the light beam is detected by the detecting means until it is detected thereby again, a plurality of light beams are irradiated based on the specified number of clocks. Therefore, even if unevenness occurs in the deflecting speed of the deflecting means, dots can be formed at the same intervals in scanning a plurality of scanning lines. Thus, it is possible to prevent discontinuous joints occurring in each of the images formed with a plurality of light beams.

By applying a matrix in consideration of a dot direction which may be broken by the interpolation processing at the time of the screen processing, conversion in which a way of locating the half dot maintains relation of vertical inversion in a subscanning direction is carried out, and less-than-one-pixel-basis correction is carried out.

Abstract: A printer not optically correcting bends and inclinations of scanning lines needs to execute such control as to electrically correct them. However, a conventional correction method has a problem that this correction causes an image defect such as an image streak or an uneven concentration in a specific area. A correction method of the present invention, when an input image has only one color, executes only correction by a second correction component which corrects distortions in a main scanning direction without executing correction by a first correction component which corrects bends and inclinations in a sub-scanning direction, and when an input image has two or more colors, executes both of correction by the first correction component and correction by the second correction component. This control can reduce the frequency of occurrence of an image defect.

Abstract: Image distortion is corrected in a color printer wherein print units for a plurality of colors are aligned to form a color image by superposing images formed by the print units. A quantity of image distortion is detected, and correction data of main scan address and subscan address are calculated and stored according to the detected image distortion for each main scan address. When input color image data are corrected, printing position is corrected in combination of address change with density interpolation. When the correction data exceeds the maximum correction range, the correction data are replaced by the maximum in the correction range for distortion correction. Further, in the image data correction, after the image data are converted to data having a smaller number of gradation levels, the data are delayed according to the serial arrangement of the print units. Then, the delayed data are converted again for printing.
