Afaik you can also detect images that are present for a millisecond (eg white screen with one black frame at 1000fps).

You can detect very small numbers of photons (sometimes a single photon), your eyes don't care about the frame rate. The question is, can you tell the difference between 120FPS and 240FPS

Still an excellent question! There's this (no proper references) that seems to suggest ppl lose the ability to make meaningful judgements about frame rate (or ~differentiate differences) after around 150fps:

This (150>120) seems to suggest that many people would be able to see (maybe it'd be better to call it "feel" the difference at this point) the difference between 120 and 240fps. but they most likely couldn't tell 150 from 240fps.
