Since the pseudo-interlacing is enabled during this mode, two distinct fields are obtained. For a
stationary object in the field-of-view, this produces two interlaced fields; or full vertical resolution.
Since the two integration periods are 1/60 sec apart, any movement in the field-of-view between
the two integration periods will be seen as inter-field flicker.
Therefore, if shuttering is used to "stop" motion, only one field (or half the normal vertical
resolution) per integration period is usable. If shuttering is used for exposure control and the
field-of-view is static (relative to the 1/60 sec between successive exposures), full vertical
resolution is available.
Both the Genlock and the Asynchronous Reset options have been found to work successfully
with the shutter mode, although the “slowest” shutter speed obtainable with Genlock or
Asunchronous Reset is approximately 600µsec (instead of 1/1000 sec).
