摘要： A method and apparatus for processing a digital image to reduce moiré artifacts while preserving or improving detailed features. Pixels may be categorized as halftone and/or detail pixels and filtered accordingly. A pixel may be categorized as halftone if intensity values over a first window laid over that pixel vary by less than a first predetermined threshold. A descreen filter may be applied to halftone pixels. The remaining pixels that are not categorized as halftone pixels are analyzed as potential text elements. A PTE may be categorized as a detail pixel if intensity values over a second window laid over that pixel vary by more than a second predetermined threshold. The second window may be smaller than the first window. A sharpening filter may be applied to detail pixels.

摘要： Method for shading an optical sensing element of an optical sensor. Reference values are sequentially obtained of the output signal of the sensing element while relatively moving the optical sensor including the sensing element over a shading reference target. An edge detection filter is applied to each of the reference values obtained in step a) in determining if each of the reference values is or is not from an optical defect on the shading calibration strip. An average is calculated of the reference values obtained while excluding each of the reference values determined to be from any optical defect in calculating the average. The output signal of the sensing element is calibrated to the shading reference target using at least the calculated average.

摘要： A method of selective dithering for enhancing the printability of an image, including receiving input pixels of an original input image and identifying the pixel classification of the input pixels, where the pixel classification characterizes each of the plurality of pixels based, at least in part, on their respective gray values. Thereafter, a dither input is added to at least some of the input pixels to generate a filtered and dithered image, where the strength of the dither input applied to generate the filtered and dithered image is based on the pixel classification. Full dither may be applied for smooth pixels, and little or no dither may be applied for edge pixels.

摘要： One method for determining a gray background value of a scanned document having left, right, top and bottom edges includes obtaining a scanned image of a horizontal strip which includes at least one portion of the document and which includes at least one non-document area, and includes creating a histogram of pixel values, of the horizontal strip, inside the document edges while excluding from the histogram pixel values, of the horizontal strip, located outside the document edges. Another method for determining a gray background value includes obtaining a scanned image of a vertical strip. One method for determining skew of a scanned document includes obtaining a scanned image, which includes a leading document edge, using vertically-displaced successive horizontal scan lines, includes determining points of the leading edge, and includes fitting a line to the points. Another method for determining a skew uses horizontally-displaced successive vertical scan lines.

摘要： The input pixels in an image to be halftoned using error diffusion are dithered using a first type of passband dither. A second type of passband dither may also be added to a thresholding matrix used in halftoning. This second type of passband dither may be the same as the first type of passband dither. In such case, the second type of passband dither is a scaled multiple of the first type of passband dither. The halftoning process may be implemented in an application specific integrated circuit.
