摘要： An optical scanning device projects an image onto a photoreceptor within a print system. A laser light source generates a plurality of light beam outputs, wherein the light beam outputs are arranged in a two-dimensional parallelogram array within a substantially horizontal axis and a substantially vertical axis that is perpendicular to the horizontal axis. The two-dimensional parallelogram array has an odd number of rows of light beam outputs, wherein each row has an equal even number of light beam outputs. A rotating polygon mirror includes a plurality of deflecting surfaces, each of the deflecting surfaces deflects the light beams emitted from the laser light source. The light beam output array projects a first swath N onto the photoreceptor via the rotating mirror and swaths [N+1, N+2, . . . ] are subsequently placed at a level one-half down the number of light beam outputs of the previous swath. Each swath has the identical number of light emitting outputs as the two-dimensional array.

摘要： As provided herein, there are supplied teachings to systems and methods for resizing a digital uniform rosette halftone image composed of multiple colorant separations, by using uniform rosette halftone tile parameters. One approach entails receiving into a digital imaging system, a digital uniform rosette halftone image and a desired resizing factor for that digital uniform rosette halftone image. Subsequently the system will define uniform rosette cells within the color uniform rosette digital halftone image. From the defined uniform rosette cells, a number of uniform rosette halftone tile seams are determined for manipulation. The orientation of the number of uniform rosette halftone tile seams is dictated by the received desired resizing factor. An energy map of the digital uniform rosette halftone image is determined according to an energy metric derived from the multiple colorant separations. The energy of the number of uniform rosette halftone tile seams within the energy map is determined so as to provide indication of at least one low energy determined uniform rosette halftone tile seam. A resizing of the uniform rosette halftone image by manipulating the at least one low energy determined uniform rosette halftone tile seam is performed so as to obtain a resized uniform rosette halftone image. The resized uniform rosette halftone image may then be printed on a printer.

摘要： The teachings provided herein disclose a method for corner sharpening in the display of a bitmapped digital image. The method includes the steps of selecting a target pixel location within the digital image; observing a set of pixels within a pixel observation window superimposed on the digital image relative to the target pixel location; generating edge-state codes for a plurality of pairs of neighboring vectors of pixels within the pixel observation window; generating corner-identification codes from the plurality of edge-state codes using at least one look-up table so as to thereby identify corner pixels; and, assigning a pixel value in an output image plane in a location corresponding to the target pixel in the input image, such that assigned value extends a corner where indicated by a corner identification code, thereby producing a sharpening effect. The method may be used for improving the print quality of line-art corners and other fine details as found in both font and image data.

摘要： A method for sharpening the corners of digital image data within an anti-aliasing image path so as to overcome corner rounding when displayed or printed. The method comprises stepping a window across the image data and comparing that windowed data to templates or performing Boolean logic and arithmetic operations on the image data. Upon determining a match or a corner detection, pixel values are substituted in the identified pixel locations to achieve a clustering of the substituted pixel values about the corner structure producing a corner-enhanced digital image. Filtering and sampling are then performed according to an anti-alias operation to the corner-enhanced image to produce an anti-aliased corner enhanced image. The data substitution will achieve a localized clustering or “ear” of toner/ink, or in the alternative for inside corners the localized clustered absence of toner/ink. The result of this clustering is a sharpening of the corners so that they display or print as intended by the bitmap.
摘要翻译：一种用于在抗锯齿图像路径内锐化数字图像数据的角的方法，以便在显示或打印时克服角圆。该方法包括跨越图像数据步进窗口，并将该窗口数据与模板进行比较，或对图像数据执行布尔逻辑和算术运算。在确定匹配或拐角检测时，在识别的像素位置中替换像素值，以实现关于角部结构的取代像素值的聚类，从而产生拐角增强数字图像。然后根据对角增强图像的抗混叠操作来执行滤波和采样，以产生抗锯齿角增强图像。数据替代将实现调色剂/墨水的局部聚集或“耳朵”，或者在内部角落中可选择地定位聚集的墨粉/墨水不存在。这种聚类的结果是锐化锐角，使得它们按位图显示或打印。

摘要： Disclosed herein is a method and apparatus for moiré-free enhanced color halftone printing of color image separations for an arbitrary number of colorants. The method and apparatus utilizes a plurality of halftone screens, >4, to produce outputs that are moiré free and form hexagonal periodic rosettes. The relatively large number of screens can be used for enhanced printing applications, such as printing with high-fidelity colorants, light colorants, or special colorants, such as white, metallics and fluorescents. The method and apparatus provide for defining rosette fundamental frequency vectors VR1, VR2 that satisfy a length and sum requirement to meet visual acceptability standards according to |VR1|>fmin, |VR2|>fmin, and |VR1±VR2|>fmin; defining N halftone screens for colorants i=1, N, respectively possessing first and second frequency vectors (Vi1, Vi2), where no two screens possess identical fundamental frequency vector pairs; and selecting fundamental frequency vectors for the N halftone screens according to (Vi1, Vi2)=(mi1VR1+mi2VR2, ni1VR1+ni2VR2) for integer m's and n's, where at least one fundamental frequency vector or its conjugate must also satisfy one of the following: Vik=VR1, Vik=VR2, and |Vik>2 max [|VR1|, |VR2|].
