You can calculate the reset runtime using this formula:
Reset Runtime = tRow x (ROI Height -1)
You can calculate the total readout time using this formula:
Total Readout Time = [ tRow x (ROI Height) ] + C

µs
You can calculate the total runtime using this formula:
Total Runtime = Exposure Time Parameter S Total Readout Time
The cameras, except the acA1920-25, acA2500-14, acA3800-14, and acA4600-10 cameras, can
provide an exposure active output signal that will go high when the exposure time for line one
begins and will go low when the exposure time for line one ends.
If the camera is operating with the rolling shutter in ERS mode and you are using the camera to
capture images of moving objects, the use of flash lighting is most strongly recommended. The
camera supplies a flash window output signal to facilitate the use of flash lighting.
