    摘要: A system and method for rendering an image file for outputting a copy of an image represented by the image file. In some embodiments, rendering the image includes generating an output file, such as an output bitmap based on a predetermined halftone. In one embodiment, the system comprises an input module, and a processor. The input module obtains a page description of the image to be output. In some instances, the page description includes one or more level masks designed to impart corresponding transparency levels to one or more objects in the page description. The processor (i) detects the one or more level masks in the page description, (ii) determines the one or more corresponding transparency levels of the one or more detected level masks, (iii) obtains one or more custom masks that correspond to the same one or more transparency levels as the one or more detected level masks, wherein the one or more custom masks are designed based on the predetermined halftone, and (iv) replaces the one or more level masks in the page description with the corresponding one or more custom masks.

    摘要: In an input scanning system, as would be present in a digital copier, a “template” of similar visual elements or objects, such as logos and other designs, is detected among a series of scanned images. The common objects form a reference image against which subsequently-recorded input images are compared. If bounding boxes around objects in the input images match those in the reference image, the objects in the bounding boxes are attempted to be matched to those in the reference image. If objects in the input image and reference image match, then the image data from the input image is coded using a pointer to the corresponding object in the reference image.

    摘要: Systems and methods are provided for calibrating image sensors. In some embodiments, a processing module of an image system can automatically perform a self-calibration process after a production unit of an image sensor has been integrated into an end product system. For example, the processing module can calibrate a production unit based on one or more reference pixels of the production unit, where the one or more reference pixels have minimal color filtration. In some embodiments, the processing module may perform local calibrations by correcting specifically for spatial variations in a color filter array (“CFA”). In some embodiments, the processing module can perform global calibrations by correcting for optical density variations in the CFA. In some embodiments, a processing module can determine whether the cause of production variations is related to production variations of a CFA or production variations of an infrared (“IR”) cutoff filter.

    摘要: Stereoscopic imaging devices may include stereoscopic imagers, stereoscopic displays, and processing circuitry. The processing circuitry may be used to collect auto white balance (AWB) statistics for each image captured by the stereoscopic imager. A stereoscopic imager may include two image modules that may be color calibrated relative to each other or relative to a standard calibrator. AWB statistics may be used by the processing circuitry to determine global, local and spatial offset gain adjustments to provide intensity matched stereoscopic images for display. AWB statistics may be combined by the processing circuitry with color correction offsets determined during color calibration to determine color-transformation matrices for displaying color matched stereoscopic images using the stereoscopic display. Gain and color-transformation corrections may be continuously applied during operation of a stereoscopic imaging device to provide intensity-matched, color-matched stereoscopic images in any lighting condition.
