The up image is the captured interleaved frame (HD1080i50,upper field first)from QUAD HDMI Recorder card,it seems the interleaved frame is stored as two seperated field images,so I try to copy the upper field image to line1,line3,line5,...,and copy lower field image to line2,line4,line6,...,to combine it as field-interleaved image,but the combined image is wrong,it looks like field is not in the correct line; I also try to copy upper field to line2,line4,line6,lower field to line1,line3,line5,but I failed too; So how to combine the field-seperated image to field-interleaved image?
