摘要：
This invention presented a universal de-interlacing method and system by the motion detection, the motion adaptive interpolation, the directional edge interpolation, the 3:2 pull-downed detection and the 3:2 Pull-Downed recovery. Four-field motion detection can detect the motion area and the still area. By cooperating with the motion adaptive interpolation and the directional edge interpolation the picture possesses the very clear quality, high contrast, and high resolution. The 3:2 pull-downed detection and the 3:2 Pull-Downed recovery can detect the 3:2 Pull-Downed movie sequence and recover the interlaced fields into a progressive frames universally without too much overhead of computational power.
摘要（中）：
本发明通过运动检测，运动自适应插值，方向边缘插值，3：2下拉检测和3：2下拉恢复提出了一种通用的去隔行方法和系统。 四场运动检测可以检测运动区域和静止区域。 通过配合运动自适应插值和方向边缘插值，图像具有非常清晰的质量，高对比度和高分辨率。 3：2下拉检测和3：2下拉恢复可以检测3：2下拉电影序列，并将交错字段恢复为逐行帧，而无需太多的计算能力开销。
