6.3.4 Reset Continuous (RCT) trigger mode
The RCT mode operates like EPS(edge preselect)mode with smear less function. An external
trigger pulse will immediately stop the video read out, reset and restart the exposure, then
operate as normal mode until the next trigger. After the trigger pulse is input, a fast dump
read out is performed. In the CM-141MCL/ CB-141MCL, this period is 6.65ms which is 211L.
The exposure time is determined by the pre-set shutter speed. If no further trigger pulses
are applied, the camera will continue in normal mode and the video signal is not output.
The fast dump read out has the same effect as “smear less read out”. Smear over highlight
areas is reduced for the trigger frame. The reset continuous trigger mode makes it possible
to use triggering in conjunction with a lens with video controlled iris.
