Pulse Width Trigger Shutter Mode
This is a mode to start exposure by inputting trigger signals, and to set its exposure time with trigger pulse width.
・
Set "TriggerSelectorAndActivation" to "FrameStartLevelHigh" or "FrameStartLevelLow".
・
Trigger cycle needs to be longer than FVAL period (
≒
1/framerate).
・
Trigger operation is CLK sync H-V sync reset.
・
The minimum trigger width is 30µs.
・
Functionally, there is no upper limitation for pulse width. However, at long exposure, some noises, lines, pixel-wise
FPN, and shading might be noticeable.
