Trigger Delay - GigE VA Series User Manual

VA GigE series
8.3.3.2 Double Exposure
When the Double Exposure mode is selected, two frames can be acquired in rapid succession using a single
trigger signal. The exposure time for the first frame begins according to the current camera settings when the
trigger signal is applied to the camera. Once the exposure for the first frame is complete, the camera reads out
the sensor data. At this point, the exposure time for the second frame begins. Then, the camera reads out the
sensor data for the second frame after reading out the sensor data for the previous frame.
In the Double Exposure mode, the exposure time for the second frame equals to the readout time of the first
frame. There is a just few microseconds (or dozen of microseconds) between the point where the exposure time
for the first frame ends and the point where the exposure time for the second frame begins. This is because the
camera cannot react to the exposure start trigger signal while reading out the sensor data for the first frame. At
this point, the camera outputs a strobe out signal reflected the exposure time for the first frame.

Trigger Delay

The Trigger Delay feature specifies a delay (in microseconds) that will be applied between the receipt of a trigger
signal (software or external) and when the trigger will become effective.
The Trigger Delay can be specified in the range from 0 to 10,000,000 ㎲ (equivalent to 10 s).
The Trigger Delay will not operate if the Trigger Mode parameter is set to Off.
