Interlace to progressive conversion

摘要

Interlace to progressive conversion methods are used to interpolate the missing lines in an interlaced video signal. The method provided by the present invention selects one of different filter algorithms according to a result of a motion detection process of the interlaced video signal, wherein the different filter algorithms differ from each other in a ratio of spatial and temporal filtering. An advantage is a high quality of the resulting signal in the progressive mode regardless of whether the interlaced video signal shows motion or not. <IMAGE>
