Abstract: A method for enhancing the print quality of halftone images makes use of error diffusion to perform halftone image processing to a document. After an RGB image is obtained by scanning the document, a high-pass filter is used to detect the edge characteristics and edge directions of the RGB image. Next, during the error diffusion process, a condition quantizer is used to separately process pixels both with and without edge characteristics based on the edge characteristics, gray scale values, and accumulated errors of input pixels. Pixels without edge characteristics can thus have a smoother distribution by means of error diffusion, and the pixels with edge characteristics can have a concentrated distribution, thereby the edge of the text in the document can be sharpened.
