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.
