Normal Shutter Mode
At normal shutter mode, consecutive video signals are read with EIA compliant 2:1 interlaced scanning.
With shutter function, rapidly moving objects can be captured clearly.
When adding external sync input, please follow the HD/VD input conditions shown below for 30fps
mode.
Restart-Reset Mode
With adding EXT VD at random timing with over 1VD, data for one screen image is read out. This
function is useful when sensitivity with regular exposure time is not sufficient or when indicating the
locus of moving object. ODD/EVEN field is determined by EXT HD/VD phase.
