Abstract
An image processing method and an apparatus capable of employing the method, which smooth notches on outlines and output an image of high quality having smooth outlines. First, edges to be smoothed are determined, then numbers of consecutive black dots in the horizontal and vertical directions are counted from originating points in the determined edge. Further, dots for correcting an original image are calculated based on the counted numbers of consecutive black dots. Thereby it is possible to perform the high speed smoothing correction efficiently, facilitating production of a high quality printing apparatus for a reasonable price.
