Abstract
Systems and methods are described that facilitate compensating for slow scan direction displacement (e.g., skew and/or bow) defects in a raster line using slow-scan electronic registration. Input image data is buffered at low-resolution (e.g., 600 spi or the like). Displacement compensation is performed as the low-resolution contone image data is converted to high-resolution (e.g., 2400 spi or the like), and a displaced (e.g., staggered) halftoning threshold array is indexed to account for detected displacement. Displacement compensation is again performed during conversion of the high-resolution contone image data to high-resolution binary image data that is used to generate an output image.
