I don't know about writing but reading and processing a 552x91 image (10K file) took .4 seconds real time (.3 user). 552x91 is the approximate size of the rectangle of the goals. We haven't been able to measure the camera write time accurately, but I've been told it's less than 750 ms. Obviously for ball tracking that's not quick enough but as you say detecting hot mode is easily done.
Just curious, how are communicating back to the cRio/LabView?
