摘要 <p>There is provided an image processing method whereby a slope at a first position on an outline of character data in input image data is extracted and phase data at a second position on a background of the character data is also extracted. The second position exists in the normal direction of the slope at the first position and is away from the first position by a predetermined distance. The phase data is based on states of black pixels in a plurality of predetermined directions at a target point. The predetermined distance depends on the size of character data. <IMAGE></p>
