10.2.4 Reset Continuous (RCT) trigger mode
The RCT mode operates like EPS (edge pre-select) mode with smearless 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 readout is performed. In the CM-140GE/ CB-140GE, this period is
10.71ms which is 350L and in the CM-140GE-UV, it is 20.615ms for the same 350L. 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 “smearless 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.
This mode is available only in LVAL_async mode.
