    摘要: A mechanism for providing edge enhancement or attenuation in a vector error diffusion process includes warping a marking decision color space as a function of at least one pixel value of a target pixel. The warping changes the membership of sets of error modified pixel values associated particular sets of marking. The warping is controlled by a function of pixel values of a target pixel from an input image. Therefore, the warping is constant for uniform portions of the image. Since pixel values change at edges or where colors change, a mechanism is provided for the presence of edges to influence the vector error diffusion process. Selection of the function by which the marking decision color space is warped provides a means for controlling the aggressiveness of the edge enhancement or attenuation. Equivalent processing includes warping or adjusting error modified pixel values according to corresponding functions.

    摘要: Engine response curves (RCs) can be used for streak compensation for printed documents. A feedback control paradigm can be included to effect RC compensation. Singular Value Decomposition (SVD) can be used to represent each RC in the collection of spatial RC data as a linear combination of basis vectors. RCs are approximated by selecting the first few basis vectors, the approximation aiding in noise rejection and reducing computation in the controller by reducing dimensionality of the RC data from gray levels to the number of SVD bases selected. An optimal subset of RCs is selectable from the set of approximated RCs by clustering the SVD weights, the clustered SVD weights producing TRCs that span all engine response RCs generated by a printer. Compensation RCs are constructible using reduced number of bases and clustered SVD weights.

    摘要: As set forth herein, computer-implemented methods and systems facilitate halftoning using a parametrically controlled spot function based on triangle tessellation, which in turn facilitates dot growth control of periodic halftone using an irregular seed structure. The spot function determines the shape of the halftone dot used to reproduce a given pixel. The spot function is well suited for growing halftone dots arrayed on a non-regular grid and can also be used for grids with regular order. The spot function includes adjustable parameters for controlling its sharpness and slope.

    摘要: A method of achieving process-direction sub-raster magnification adjustment using non-redundant overwriting. The raster imager provides overwriting while the image path provides non-redundant data for each pass according to the desired magnification adjustment. The same laser power level can be used for the multiple writes, or optionally, it may be varied to further improve spatial resolution of the adjustment.

    摘要: Images that include halftone structures are sharpened. A copy of received halftone image data is blurred, thereby reducing a detectability of edges of the halftone structures. Edges remaining in the blurred image data are detected. An edge enhancement image is generated based on the detected edges. The original received halftone image data is combined with the edge enhancement image, thereby generating sharpness enhanced image data having halftone structures. The sharpness enhanced image data having halftone structures can be rendered through a halftone screen that is compatible with a halftone screen that was used to generate the originally received image data. Alternatively, the sharpness enhanced image data having halftone structures is rendered according to error diffusion techniques, such as, rank order error diffusion in order to achieve or maintain dot or halftone structure compaction.
