Can Face ID feature still work in outdoor environment, specially under sunlight?

I think we can all be fairly confident that a key feature in Apple's flagship new phone will work in sunlight, yes.

I'm not sure if the weather in California really provides enough sunlight for sufficient testing...

There's sunlight in California? Good gravy I need to get out more.

I asked this question because as I know, some devices that use similar technology with IR emitter and IR camera don't work in sunlight. They're Microsoft Kinect, Intel Realsense, Leapmotion... That happens because sunlight is a bigger IR source that overlap on IR light from IR Emitter, then makes the IR camera cannot get the correct dot images.

Before the iPhone implemented it, every fingerprint scanner I used either took forever or was miserably unreliable. I was skeptical iPhone's scanner could do a good job. It proved me wrong.

Similarly, every facial recognition technology I have used has either taken forever or was miserably unreliable. This time I'm not betting against Apple.

It's a reasonable question -- the relative brightness of the sun vs the phone's IR emitter. (Not deserving of a downvote, imo)

It would be cool if the article addressed questions like this.
