Abstract: The present invention provides a method and apparatus for de-interlacing video data by using a horizontal motion vector of a horizontal motion between fields. The horizontal motion regarding a target pixel of a frame is compensated if the horizontal motion vector is found to be substantially not null according to the pixels residing in the fields determined by the horizontal motion vector. This results in an upgraded quality of image after the de-interlacing process.

One of the proposed de-interlacing methods includes edge detection of a target region corresponding to a target position. When the target region is assumed to include an edge that is considered stationary, and if the target position is on a stationary side of the edge, then a pixel value for the target position is generated by inter-field interpolation.

Abstract: The present invention provides a video detecting device including a first pixel detector, a second pixel detector, and a determining unit. The first pixel detector compares the intensity of a target pixel of a target scan line in a first field with the intensity of first comparing pixels of scan lines corresponding to the target scan line in a second field to generate a first detection value corresponding to the target pixel. The second pixel detector compares the intensity of a reference pixel of a nearby scan line in the second field with the intensity of second comparing pixels of scan lines corresponding to the nearby scan line in the first field to generate a second detection value corresponding to the reference pixel. According to the first and second detection values, the determining unit generates a diagnostic value which helps determine sawtooth occurrences in video frames.
