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 and iterative determination of energy metrics. 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 screen parameters to define uniform rosette Holladay halftone tiles 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. The energy of the number of uniform rosette halftone tile seams is determined according to an energy metric so as to provide indication of low energy determined uniform rosette halftone tile seams. A resizing of the uniform rosette halftone image by iteratively deleting a number of the 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： Image data is scaled, rotated and/or otherwise manipulated. Diffusive effects of associated interpolation and/or re-sampling are compensated for, or corrected, by applying an adaptive packing form of error diffusion to output data of one or more manipulating transforms. For example, rank order error diffusion is applied to output data of a manipulating transform, thereby restoring compaction to otherwise diffuse halftone structures (e.g., halftone dots, lines, etc), saturated text and/or other small, high contrast image elements.

摘要： Sub-raster registration errors are compensated for through non-redundant overwriting. Data from adjacent rasters is written to a particular output raster so that the adjacent rasters share an influence at a point actually written to by a rendering device, thereby compensating for a sub-raster component of a registration error associated with writing to the particular point. If two writing passes per raster are used and the writing passes have equal influence (e.g., are written with equal power), then writing data from a first raster during a first pass and writing data from a second raster adjacent to the first raster during a second pass compensates for a sub-raster registration error of half a raster spacing. If two writing passes are associated with different influence (e.g., are written with ⅓ and ⅔ power respectively) and/or if additional writing passes are used, then addition sub-raster positions can be compensated for or emulated.

摘要： Image object adjustment is achieved without lookup tables or templates. Cross sections of image objects are modeled. Parameters of the modeled cross-section are adjusted in accord with a desired effect. For example, a width of the modeled cross section is change. The changed cross section model is sampled to determine a new value for a target pixel. For instance, vector windows are applied to a target pixel. If a candidate image object is included in the vector window, a cross section thereof is modeled as a rectangle. A parameter of the model, such as a width, is adjusted. Area sampling of the adjusted model can be used to determine a new value for the target pixel. Accuracy can be increased by blending information associated with a plurality of vector windows.

摘要： Methods and apparatus for antialiasing images that contain one or more image objects such as colored text, line art, and graphical objects, such that the edge pixels of an antialiased image object will exhibit relatively uniform values, and the appearance of the image object is thereby improved. In one embodiment, an improved antialiasing filter is employed to detect at least one region within the received image. Upon detecting a region containing a background image level that adjoins an image object having pixel values in a range other than a range of limit values, the antialiasing filter sets the pixel values of the edge or border pixels of the image object to substantially the same value. Selection among a logical filter operation and an averaging filter operation may be adaptively employed in the antialiasing filter in order to obtain the desired uniformity of pixel values.

摘要： A system and method for printer control and color balance calibration. The system and method address the image quality problems of print engine instability, low quality of color balance and contouring from the calibration. The method includes defining combinations of colorants, such as inks or toners that will be used to print images, defining a desired response for the combinations that are to be used and, in real time, iteratively printing CMY halftone color patches, measuring the printed patches via an in situ sensor and iteratively performing color-balance calibration based on the measurements, accumulating corrections until the measurements are within a predetermined proximity of the desired response. The calibration is performed on the halftones while they are in a high quantization resolution form.

摘要： An imaging apparatus includes an image acquisition section which converts a physical image to a digital image representation using non-ideal optics such as an array lens. This image acquisition results in a digital image representation containing errors or artifacts. A memory in data communication with a processor stores a plurality of compensation parameters selected for use in correcting errors induced by the lens array. The compensation parameters are determined by performing a lens characterization which includes measuring lens performance at a plurality of locations along the lens. After the processor adjusts the image representation, the post-compensated digital image representation may be further processed, stored, transferred, and the like. According to another embodiment of the invention, a non-ideal array lens induces errors in an image representation during a printing or output operation. Similarly, an image processor applies pre-compensation parameters to the desired or ideal image representation in electronic form to compensate for errors which are known to be induced by the lens during the output operation. Accordingly, when the pre-compensated image representation is output using the non-ideal lens, the physical image output appears to have been printed with an ideal lens.
