  • Patent number: 7987241
    Abstract: What is disclosed is a system and method for automatically registering and de-registering custom EIP service application solutions across a fleet of multi-function document reproduction devices in peer-aware network. As described herein, through an implementation of the present method, custom EIP service solutions installed on one computer platform can be automatically replicated and shared across a fleet of multi-function devices without requiring manual registration of the newly deployed service with each device. Registration makes the service user-selectable directly from the device's UI. Further, when a service goes off-line or otherwise becomes available, the service is automatically de-registered with devices whereon the service has been registered. A single instance of an application service can be rapidly replicated without manual intervention. The present system is scalable from a few nodes to many nodes as additional resources are brought online.

  • Patent number: 7978371
    Abstract: What is disclosed is a system and method for improving vector halftoning in ink-jet printers capable of dot-on-dot printing. In one embodiment, n input Ci/Mi/Yi channel and a colorant Ki are received. If any of the Ci/Mi/Yi is greater than 100?Ki then that channel is clipped to 100?Ki. Next, a minimum total coverage area of a secondary color RGB dot required to achieve a remaining CMY coverage area is determined. If the minimum total coverage area is non-zero, then the following steps are performed. Each of a primary output Co/Mo/Yo is determined. Each of the primary outputs is then scaled by a ratio of the remaining primary color area over the total remaining toner coverage. The results are sorted and secondary color RoBoGo outputs are determined from the sorted results.

  • Patent number: 7953288
    Abstract: What is disclosed is a novel system and method for edge transition detection when improve print quality when rendering via high-addressable vector error diffusion in an image processing environment. In order to detect an “ideal” edge and compensate for the adverse effects described in the background hereof, local pixels are detected and local gradient values are calculated and compared against an adjustable threshold to determine the interpolation method needed for that particular pixel. A nearest neighbor interpolation is performed when a local gradient exceeds a predetermined threshold. For example, if the difference between two successive pixels is greater than “200”, nearest-neighbor interpolation is used to calculate the intermediate sub-pixel level(s). Otherwise linear interpolation is used. Dynamically switching between these two interpolation schemes significantly improves the integrity and sharpness of the edges.

  • Patent number: 7952764
    Abstract: What is provided are a novel system, method, and computer program product for hierarchical (telescopic) color error diffusion which effectively controls the dot distribution for both primary and secondary dot formation which covers the class of error diffusion that follow telescopic dot firing constraint principles. In one example embodiment, an input CMYK ink coverage is received. The input CMYK ink coverage is transformed into a CMYKRGB domain using a CMYK to CMYKRGB conversion. A weighted error value can be added to each color component of the CMYKRGB domain. The color components of the CMYKRGB domain are hierarchically grouped into a plurality of subgroups based on relative dot visibility. More visible subgroups are half-toned earlier to achieve maximum uniform dot distribution. Dots of specific color channels within subgroups are fired based on thresholding and a set of decision rules provided herein.

  • Patent number: 7933044
    Abstract: Disclosed herein is a Moiré-free color halftone configuration for clustered dots. Unlike conventional methods, the disclosed method produces periodic hexagon rosettes of identical shapes. These exemplary hexagon rosettes have three fundamental spatial frequencies exactly equal to half of the fundamental frequency of the three halftone screens. The resultant halftone outputs are truly Moiré free, as all the fundamentals and harmonic frequencies are multiples of and thus higher in frequency than the rosette fundamental frequency. The halftone outputs resulting from the employment of the exemplary rosette design methodology provided herein, are also robust to the typical misregistration among color separations commonly found in color systems.

  • Patent number: 7916350
    Abstract: What is disclosed is a novel system and method for minimizing visual artifacts, such as ROS skew and laserbeam bow, in a brick-layer halftone structure. The present method involves determining a line pattern from ROS skew and laserbeam bow profiles which traverses through successive halftone cells displacing pixels along scanlines in the process direction. The amount of displacement is varied as a function of the cross-process location as determined by the line pattern. Pixels along scanlines are shifted in a direction defined by the error profiles. In each halftone cell within which the line pattern traverses, extra pixels (empty pixel spaces created in the halftone cell by the shifting operation) are filled with lost pixels (pixels bumped from the halftone cell during the shifting operation) such that overall density of the halftone cell is maintained. The lost pixels are buffered such that lost pixels are preserved.

  • Patent number: 7916349
    Abstract: What is disclosed is a system and method for diffusing pixel error in a halftoning process in a color management system. The present method divides a modified CMYK input into a real and imaginary portions. The real portion is the coverage achieved by a physically realizable positive dot. The imaginary portion comprises a an imaginary negative dot and an imaginary excess dot. Each of these dots are processed separately, on a per-pixel basis, in a novel CMYK to CMYKKpRGB conversion discussed in detail herein. Hierarchical thresholding is preformed on the conversion output to produce a high-quality halftone result. A cumulative pixel error sum is derived therefrom and combined with the input CMYK coverages of a next pixel. All pixels are processed. The halftone output generated hereby has the pixel error compensated. Other embodiments are provided.

  • Patent number: 7907305
    Abstract: What is provided herein is a novel system and method for estimating the amount of color in a document. In one embodiment, a binary CMYK input image is received. Each of the CMYK plane is received at an offset from the previous plane, i.e., the 4 planes are not received simultaneously. Each plane is divided into M×N tiles. Pixel values of all four planes are examined separately and the number of on-pixels is counted for each plane. The number of on-pixel counts for each tile are aggregated for each plane. Total on-pixel counts are used to estimate the total number of white, black, color, and gray pixel counts. The total counts for all planes are used to estimate the amount of color. A document is determined to be color if the amount of color exceeds a predetermined threshold. A color billing strategy is determined based on the estimated color amount.

  • Patent number: 7903285
    Abstract: What is provided are a novel system, method, and computer program product for estimating the amount of color in a document to be printed, with the capability to handle composite black. A color billing strategy can be dynamically determined based on the amount of color in the document. In one embodiment, a contone CMYK image is examined and the level of color is estimated based on information extracted from the four planes simultaneously. More specifically, it examines the pixel values from all the four planes to calculate the number of white, black, color, and gray or neutral pixel counts. Input CMYK values can be pre-adjusted via a look-up table to take into account neutral balance characteristics. The difference among the adjusted color values is compared against a threshold that is input level dependent. Color is further subdivided into fuzzy colors to handle highlights and neutral areas.
