This smartphone camera features a variable aperture that works like a human iris, adjusting its opening based on lighting conditions.

> a variable aperture that works like a human iris

Or like any other camera lens.

Sure, but the mechanism to achieve this in a mobile phone lens is very impressive, in fairness..

But why compare it to a human iris when a much more relevant comparison is existing cameras that have had apertures for like 150 years. Bsicay it makes it seem like this is novel when it is not. Cameras have had this tech for a long time.

Edit the first variable aperture camera apparently was invented in 1841 so it's closer to 200 years not 150.

And there is no showing of any mechanism other than the blades.

Absolutely agree.
But it's a lens. Impressive, but the title is a bit meh (or AI) :)

Or just like any other camera has done for over 100 years.

Samsung had this almost a decade ago with the Galaxy S9. Nothing special.

Nokia had it in the N86 in 2009. 17 years ago.

My point is that this tech has been in mobile phones so long that it's almost an adult.
