Fig.29 Pulse width
8.7. RCT (Reset Continuous Trigger) mode
RCT mode can use ALC control to ensure that the proper exposure is set when the trigger pulse is
input. In the following drawing, the steps to achieve this combination are explained.
The exposure control is the same as in continuous mode.
When the trigger signal is input, the charge that has already been accumulated during the
current exposure period is read out very quickly and a new exposure period starts. The
exposure continues as in continuous mode.
All video level data from every exposure is transferred to ALC control.
The video output sent to the GigE interface is only the signal after the trigger is input.
