iPad Camera Big Yellow Rectangle Okay I am not talking about the little yellow square of focus, I think this is a different thing.

I was watching some online video and taking photos with my iPad when I notice a huge yellow rectangle, I would like to know what is it, does anyone knows?

It appears very fast (like 1-2 seconds) and then it goes away. I had the change to take a fast printscreen to show you, here is the image:



I notice that it was appearing when there was some movement on that part of the screen, is this live tracking movement? :o

What feature is that? and what does it do? It auto focus on that zone?
Is this something that is only available at the stock camere app I guess right?

EDIT: Also I tried to disable the Live function, that upper right first button and the yellow rectangle still shows! weird, it's okay for me, I would just like to understand what is it, thanks!

Thank you!
That's the face recognition at work.

Yellow rectangles are drawn around any detected faces to inform you that the facial colour/exposure/etc optimisations are in operation. The rectangle doesn't guarantee focus since there could be multiple faces detected. It's a feature of the stock camera app.
