Abstract
An edge direction determination method for a pixel of a display picture. The display picture has a corresponding edge map. The pixel has corresponding pixel direction pairs. First, in step (a), it is judged whether the pixel is an edge pixel according to the edge map. Next, in step (b), it is judged whether the pixel has a right-inclined edge direction or a left-inclined edge direction when the pixel is the edge pixel. Then, in step (c), the edge direction of the pixel is determined according to specific pixel direction pairs corresponding to the same inclined edge direction if a judged result in step (b) is affirmative. Finally, in step (d), if the judged result in step (b) is negative, it is judged whether the pixel has a horizontal edge direction or a vertical edge direction.
