7.7. RCT mode
Until the trigger is input, the camera operates continuously and the video signal for the auto-iris
lens is output. 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. When the accumulated signal against
the trigger is read out, FVAL, LVAL and DVAL are output too.
