Abstract
An image processing apparatus includes MTF correction part for converting an input multilevel image signal obtained via raster scanning into an output multilevel image signal through an MTF correction process, a first bi-level rendition part for performing a bi-level rendition process with respect to the output multilevel image signal so that a first bi-level image signal is produced, a second bi-level rendition part for performing a pseudo halftone rendition process with respect to the input multilevel image signal to generate a second bi-level image signal, a discrimination part for detecting whether a target pixel indicated by the input multilevel image signal is located in a halftone region of an original image or in a bi-level region thereof, and an image synthesizing part for outputting the first bi-level image signal to an output device when the target pixel is detected as being located in the bi-level region, and for outputting the second bi-level image signal to the output device when the target pixel is detected as being located in the halftone region.
