20080231748 | De-interlacing system with an adaptive edge threshold and interpolating method thereof - A de-interlacing system with an adaptive edge threshold has a motion factor generator to produce a motion factor of a position in accordance with a previous and a next fields. An adaptive edge threshold generator produces the adaptive edge threshold in accordance with a current, the previous and the next fields. A determinator determines which pixels are used to perform an interpolation on the position. When the motion factor is greater than the adaptive edge threshold, a pixel of the current field is used to perform an interpolation on the position. When the motion factor is smaller than the adaptive edge threshold, a pixel of the previous field and a pixel of the next field are used to perform an interpolation on the position. | 09-25-2008 |
