10.4. Timed-Pre-dump mode (so-called RCT) (JAI Custom)
Until the trigger is input, the camera operates continuously . At this moment, the
video signal, FVAL and LVAL are output but DVAL is not output. When the trigger is
input, the fast dump is activated to read out the electronic charge very quickly,
after which the accumulation and the readout are performed. This fast dump period
is 24.672ms. When the accumulated signal against the trigger is read out, FVAL ,
LVAL and DVAL are output too.
