| 摘要 |
It is presented a method for detecting motion in an interlaced video signal. The method can be used for generating new lines between the lines in a field. First it is calculated a difference signal across an image. This difference signal, which gives the minimum motion region of the location examined, is expanded horizontally using edge information calculated from two successive fields. The edge information may be determined with any known method or with the method presented here. In the post-processing of motion information all one-line-high motion regions are removed and indefinite motion regions are smoothed. <IMAGE>
