Right, the key "artistic" thing is identifying foreground/background, faces, interesting elements etc., and simply try to balance the exposure to create a pleasing end result. I have no idea what this thing does, or even if it uses multiple exposures (or even multiple cameras), but I was simply thinking that facial recognition/focus and automatic toning has been around for ages, it has to do something that requires fast decision (at trigger time) about exposure params.

I couldn't see whether that was done though, it could be done with most of the same effect by simply exposing e.g. +2EV and -2EV and simply deciding afterwards how to blend those images into a HDR given the image content (faces, ...)
