FWIW... I bet you could power the camera, get a still frame at 60fps, shut it down, and not see the led come on. It would be 1/60, 16ms plus or minus the amount of overhead needed, plus autofocus and exposure correction might make it impractical, but it’s definitely not a bulletproof fix.

Apple could simply make the camera take 1 second to activate.

Slow spool up embedded devices... we’re moving backwards :)

If Google Calendar thinks it’s OK to set a 500ms animation on opacity for event edit dialog - then it doesn’t seem like a 1 sec spooling for a webcam is too much :)

How much would you bet?

[SlowRobotAhead]

Considering I have a device here that has an I2C camera and in firmware I can turn it on and off at right around 25ms, I’d consider betting quite a bit.

Instead of being snarky, how about you explain why this isn’t possible. Even if it was 100ms almost no one would catch that.

I’m not being snarky, and we’re not talking about some random device you have. We’re talking about the camera on a Mac. The bet is that you can’t turn it on and off so fast as to be un-noticeable because there is a noticeable delay between that light turning on and getting an image from that camera. So I’ll gladly take the other side of that bet.
