Almost every cellphone in the world has a camera inside, but most of them stink. Samsung has a better idea, shrinking an entire iris-style mechanism into a 2mm-wide micro-shutter that's small enough to fit inside the tiniest cellphones. Instead of just momentarily activating the sensor and scanning the scene like blurry cellphone cameras do, this one snaps open and shut like a real camera.

Samsung's not saying when we might see this tech showing up in cellphones or tinycams, but could this be a sneak preview of another component of the upcoming iPhone? Hoping to see this on board this year's cellphones might be overly optimistic, but it sure would be nice to always have an acceptable camera on board an outlandishly small cellphone.
