ICP DAS USA IM-100 - Manual (Page 12)

1.4.6 Shutter (Exposure)
The camera exposure time is related with shutter speed or camera frame
rate. MAVIS IM-30/IM-100 allowed to set shutter speed range from 20us to
81900us.
While user set the exposure time (shutter speed) longer then frame
acquisition speed then camera frame rate will be reduced.
For example: if user set the frame rate in 30fps but set the shutter speed in
36000us.
Maximum exposure time (Shutter speed) = 1s / frame rate
36000us = 1s / frame rate
Camera real frame rate = 27 frames per second
