Abstract: What is disclosed is a novel system and method for reducing a size of a memory buffer used by an electronic registration correction system performing an electronic registration correction on a digital image. The present method uses column address segmentation to identify blocks of scanlines within a spatially mapped array of image pixels comprising a digital image. Advantageously, the present system and method reduces scanline buffer memory by a factor of 2n-1, where n is the number of column address segments. Buffering can be performed at almost any upstream location in the image path. The present method is well suited for high resolution imaging equipment where memory is constrained by design, cost, or space limitations.

Abstract: Techniques and systems for controlling resources used by a device's web services applications are disclosed. In one technique, web services applications release their allocated resources and enter a “sleep mode” after being inactive for a specified period of time. In one technique, a device maintains a shared pool of memory resources. The pool contains data structures that web services applications are likely to re-use. Before allocating a new instance of a needed data structure from free memory, a web services application first determines whether the shared pool already contains a currently unused but allocated instance of a data structure of the needed type, and, if the shared pool does, then the web service application uses that instance, overwriting existing data in the instance as needed. Web services applications return such data structures to the shared pool when those web services applications are finished using those data structures.

If it is determined that the rasterization result of the rendering object is cached, an image and a mask are extracted from the cache. The extracted image is rendered on a portion of the extracted mask so that a background image remains on a portion other than the portion of the extracted mask.

Abstract: Motion is introduced into a scanning operation, in addition to the motion that is inherent in any scanning operation. For example, in a flatbed scanner a linear array of scanning devices is positioned across a document in a first or “x” direction and this array is moved across the document in a perpendicular or “y” direction. With embodiments of the present technology a vibratory motion is introduced into the scanning process—not aligned with the basic “y” direction of scan. Such vibratory motion can be controlled in accordance with pre-stored data, or a random process can be employed. In some arrangements, the vibration reduces Moiré patterns. In other arrangements, the vibration causes a hidden pattern to be revealed from the scanned object. A great many other features and arrangements are also detailed.

Abstract: Methods, algorithms, software, apparatuses and systems for processing image data for imaging devices having irregular scan paths (e.g., scan paths that deviate from a conventional horizontal and/or straight line). The irregular scan paths generally correspond to actual locations of a line of output from an image output device (e.g., a printer). The method generally includes steps of selecting one or more of the input pixels, correlating a location of the selected pixel with a location on an irregular scan path, and producing an adjusted pixel based on a value of the selected pixel, the location on the irregular scan path, and/or values of one or more pixels near the selected pixel. The present invention advantageously allows for processing an input image for an output device with an irregular scan path using only enough working memory for a relatively small number of pixel rows even if the irregular scan path traverses a relatively large number of rows in the output image.
