First field: Binning line 1+2, 3+4, ...
Second field: Binning line 2+3, 4+5, ...
• The first field and the second field have two different lines binned (ver-
tical binning).
• The temporal vertical resolution is about 70% of progressive scan.
• One complete image is read out during one field. Therefore an electronic
shutter is possible.
