2.6.2.4 Rolling Shutter Internal Triggering (Overlap Mode)
Internal Triggering in Overlap Mode allows the user to perform an exposure and acquire images from the
sensor simultaneously. This is achieved by starting a new exposure for a new frame while the current frame’s
exposure is being read out from the sensor. The cycle time is the same as the exposure time entered by the
user in this scenario.
Short Exposures
When the required exposure time is less than the time it takes to read out a frame (Short Exposures), the cycle
