> In rooms lit by that, you can wave your hand or a thin object back and forth, and if you look carefully, you can perceive a "shutter" effect where you're only seeing the snapshots of its position where the light is on.
Heh, this is how I test these lamps as well. Also my camera has anti-flicker shutter which can detect it to thwart it by syncing the shutter release with flicker itself. It shows a warning when it detects is, as well.

Nice! Which cameras do this? And I wonder, how cheaply could a sensor be made to do this, that shows on the screen "there's flicker at 60Hz / 120Hz / 480Hz", if it didn't also need to be a great camera (e.g. it only captured at 480p)?
Mine is a Sony A7-III, the setting is called Anti-flicker shoot. I believe many modern mirrorless systems have the capability.
However, I wouldn't say "oh that's easy", because A7-III has two realtime DSPs, and one of them is directly responsible for things like real-time focusing, face/object/eye recognition and real time tracking, etc. So, I believe that DSP is handling the flicker detection as well.
...and A7-III is the "entry level" member of its generation. higher end models have more computing power than that.
