Reset Continuous Trigger Mode; Piv Mode - JAI CV-M2CL Operation Manual

6.1.3. Reset continuous trigger mode

The RCT mode makes it possible to use a lens with video controlled iris for intelligent traffic
surveillance applications. TR=2. The camera is running continuously, and the iris is controlled
from the iris video output. When a trigger pulse is applied, the scanning is reset and restarted,
the previous signal is dumped with a fast dump read out, and the new triggered exposure is
started. This fast dump read out has the same effect as "smearless read out". Smear over
highlighted areas are reduced for the triggered frame.

6.1.4. PIV mode

The Particle Image Velocimetry (PIV) mode (TR=5) can be used in applications where 2 images
should be taken with a very short time interval. It can only be used with strobe flash or lasers as
the only illumination. The first accumulation time is 4 µsec. The second is as long as the time for
a full frame.
