□
This is the mode to start exposure with external input trigger signals, and set the exposure time with pulse width of
the trigger signals.
□
Trigger operation is CLK Sync, and V-sync Restart system.
The delay time (Exposure Time Delay
①
) from
detecting trigger edge in the camera to actually starting exposure is
approx. 0.05μs. The delay time (Exposure Time Delay
②
) from
detecting trigger edge in the camera to end
exposure is approx. 14.26μs.
□
Pulse width min. 0.74μs to approx. 2 frames. Functionally, there is no upper limitation, but noises such as dark
noises shadings may be noticeable at long time exposure.
□
There is an exposure time period for approx. 14.26μs at the edge right after exposure output.
