Reducing edge artifacts on a digital printer |
摘要 |
An arrangment is disclosed for reducing edge artifacts produced when printing a digital image on a digital printer, which printer is capable of producing multiple output levels, said digital image being represented as a rectangular array of pixels. In this arrangement, the following steps are accomplished by: computing difference signals between a center pixel value and pixel values of a set of one or more neighboring pixels; determining a pixel correction value responsive to the computed difference signals; and computing a new center pixel value by modifying the center pixel value using the pixel correction value.
