Abstract
A method for detecting an image edge is provided. Pixel data of neighbor lines of an image are read to generate a first and a second inclined edge areas between two neighbor lines. The incline edge areas are determined by detecting whether a difference of two corresponding pixel data exceeds a preset edge threshold. Then, whether there is an overlapped or nearby portion between the inclined edge areas is determined, so as to find an incline edge.
