> Thanks, that makes sense. I did remember that sensors have "sub-pixels" that are grouped, and that you can access the sub-pixel to get "4 times" more pixels. It's sort of backwards. You can get access to sub pixels to get '4 times' more data, but pixel binning is actually the other direction -> grouping pixels together. A lot of camera performance is related to photosite size - larger photosites for light to hit, better performance/more sensitivity. The problem is that if you have a camera sensor in a DSLR, you have room for big pixels, but when you have the small sensors in phones you don't have the room for large pixels and giant MP count for marketing. So pixel binning treats groups of pixels like one large pixel to try and improve sensor performance while still maintaining large megapixel counts for marketing. In terms of innovation we haven't heard anything. There are already smartphones with pixel binning on the market. This is apple just saying Us Too unless they've released information on a new unique binning technique I haven't seen.
