Abstract
A image inclination detecting method and an apparatus achieving the method calculate distances between leading edges or between trailing edges of runs (consecutive white or black pixels) that are located on adjacent two scanning lines respectively. From occurrence frequencies of these edge distances, a representative value that may indicate an inclination of the image most clearly is found, and, based on the representative value, the inclination of the image is computed.
