Abstract
A color image edge enhancement method having the following steps: First, perform the halftone processing of a color image to produce a halftone image. Next, compare the dotting pattern of an edge pixel to be enhanced and the pixels in its perimeter in the halftone image with the contents of an edge enhancement table. Thus, search and obtain the dotting table and a corresponding dotting command having the most matching pattern. Then, divide the halftone image into the images of four color planes of cyan, magenta, yellow, and black colors respectively. Subsequently, compare the pattern of the edge pixel and the pixels in its perimeter in the respective color planes with the pattern in the dotting table to determine the color plane having the most matching pattern. Finally, execute the searched doting command to dot and enhance the edge pixel.
