Abstract
In accordance with some embodiments of the present invention, de-interlacing may be accomplished by using an edge gradient to select a best interpolation direction for several adjacent pixels between two lines of interlaced video. The interpolation of the intermediate line is performed using the best direction. Then the pixels in the line above and below are analyzed to determine whether the interpolated pixel value should actually be used in view of the possible presence of artifacts.
