<p>An error diffusion process is described herein which adds an error value to an input grey image value to produce a modified input grey image value before comparing the modified input grey image value with a predetermined threshold value. A rendering value and error is generated based on the comparison. An error equal to the modified input grey value is generated when the modified input grey value is less than the predetermined threshold value, and an error equal to the modified input grey value minus a black reference value is generated when the modified input grey value is equal to or greater than the predetermined threshold value. This error value is further compensation for pixel growth when the output of the previously processed pixel is not equal to the output of the presently processed pixel. <IMAGE></p> |
