Overlap

Configure this setting with TRG-OVLP. In trigger mode
or various modes that use an arbitrary shutter, horizontal
noise may occur on the screen if an electronic shutter
pulse SUB exists in the horizontal transferring period of
the CCD. If TRG-OVLP=1 is set, SUB is automatically
adjusted so that it occurs in the horizontal transferring
blanking period, thus enabling you to prevent the
inclusion of noise. In such a case, there is no change to
the exposure time even if there is a delay in the exposure
timing when in the trigger edge detection mode, but the
exposure time may increase slightly when in the trigger
width detection mode.

The width of the external trigger is set to 40 ms, and the period to 70 ms. At that time, the SUB resulting
from the next trigger exists in the image transferring period resulting from the previous trigger. The existence
of SUB within the horizontal transferring period results in the inclusion of noise. If SUB exists in the
horizontal blanking period, no noise occurs.
