Re: There's an opt out...?
Are you sure face recognition is that computationally intensive or power sucking? My 3 year old Panasonic Lumix camera has a face recognition feature where you take reference shots of your family members (or anyone else) which are stored in the camera. It can then find them in a group photo and make sure they are in focus/properly exposed when the shot is taken. All processing done within the camera. Even works with pets.
