Abstract: Disclosed herein is a method for detecting thin lines in image data. The method is performed by a processor to process contone image data. The processing includes thresholding a window of pixels established in the contone domain to generate a binary window of image data, and then determining characteristics associated with on pixels or runs of the binary data. The characteristics (start and end locations, length of on runs) are then thresholded. The processing in the contone and binary domain are used to determine if a thin line exists in the window of image data. The disclosed method produces better quality output images and reduces the addition of false lines in an image.

Abstract: A voltage detection circuit can include a status sensing network and a comparing network. The status sensing network can simultaneously detect a cell voltage for each battery cell of a plurality of battery cells. The comparing network can simultaneously compare the detected cell voltages with a predetermined voltage threshold by comparing the maximum of the cell voltages with a first (high-voltage) threshold, and by comparing the minimum of the cell voltages with a second (low-voltage) threshold. The comparing network can also generate an indication signal when a cell voltage does not satisfy the respective voltage threshold.

Abstract: A method for improving image quality of edge pixels, when separating an image signal into a set of image planes is provided. The method includes searching for a minimum value and a maximum value within at least one predefined neighborhood pixel window centered on a current pixel in the image signal; and conditionally switching the edge pixels to either the minimum value or the maximum value in the foreground and background planes respectively, or to a value of a specified characteristic of the current pixel, based on predetermined criteria. One such predetermined criteria for this conditional switching of the edge pixels comprises comparing the minimum or maximum luminance values in the predefined neighborhood window of the current pixel and their corresponding chrominance values to some predetermined thresholds which are characteristic of the image for the foreground and background planes, respectively.

Abstract: What is disclosed is a novel system and method for background suppression in the image path. In one example embodiment, an image is scanned and RGB color values generated for each pixel. Each of the pixels is converted into a Lab color space to obtain luminance and chrominance values. A background luminance and a luminance variation are determined for the scanned image. For each pixel, a determination is made whether that pixel is a white pixel or a non-white pixel based. If the pixel is a white pixel, an adjustment chrominance value for that pixel is determined. The value of the chrominance adjustment is modulated as a function of a difference between the white pixel's luminance and the background luminance. The modulated chrominance adjustment is applied to the white pixel. Adjusted and non-adjusted pixels are stored in a memory. A printer controller converts the pixels to an output space.

Abstract: An input scanner, such as used in a digital copier, accepts original documents on sheets of any number of possible sizes within a single job. The video output of the scanner is applied to an algorithm to determine the length, along a process direction, of useful image data on each sheet. From such a determination, a size of output copy sheets can be automatically selected, or the image can be automatically changed in size in subsequent processing. A prescan of the original documents is not required.

Abstract: A method and system for rotation-dependent halftone rendering. An image input is received from a scanning system or other source, the received image being either a contone image or an error-diffused mage. If a following right-angle image rotation is to be performed, the image is clustered by a clustering method which yields reduced file sizes with respect to the rotated orientation of the image. If no following right-angle image rotation will be performed, the binary image is clustered by an alternate clustering method which yields reduced file sizes with respect to the non-rotated image. The selective clustering includes dividing the image into a tessellation of cells and then concatenating like bits in each cell in a preferred direction for the rotated or non-rotated image. The clustered image is then rotated if necessary, and compressed.
