ROI frame rates
Values were calculated for rolling shutter (RS) mode as defined in Specified values
on page 51. To reach the maximum frame rate available for this setup, the
bandwidth for image traffic is 450 MBps.
In GRS mode, the values for maximum frame rate reached in RS mode apply to all
resolutions. In triggered mode, the values for maximum frame rate reached in free
run mode are cut in half.
