on the other hand a de interlacing method which requires less than three fields of pixels with known values for approximating values of missing pixels would translate to a significant savings of resources required for de interlacing a method requiring input information from two instead of three fields of pixels with known values would require measurably less data processing resources including hardware software memory and calculation time moreover since an de interlacing processed by a three field vt filter will first arrange the required fields in proper order before processing echoes that forms unwanted false profiles outlining the moving objects are generally at the back of the moving object but for an de interlacing processed by a two field vt filter echoes can only be seen either in front or at the back of the moving object so that the echoes of the two field vt de interlacing is considered easier to be detected while comparing to that of the e three field vt de interlacing it is noted that the vertical temporal filer used in the present invention is a two filed vertical temporal filter comprising a spatial low pass filter of two tap design and a temporal high pass filter please refer to fig3 which illustrates a two filed vertical temporal filter comprising a spatial low pass filter of two tap design and a temporal high pass filter according to the present invention in fig3 it appear that the order of the two.
