The only true innovation which has been commercialised is the Lytro light-field camera, which so far is a curiosity but very limited for any practical use. Not to say that something revolutionary might be just around the corner, but guessing what it might be is a problem.
The light-field camera is the one that keeps the entire image in varying focal lengths so you can selectively choose the focus in software later, right? Not the single-pixel camera?
