Do you know of any cameras that use this technology?
It was no exact camera model, but and advertisement for a picture sensor IP (so the company who designed it sells mainly the licenses, to be integrated by the final sensor IC maker; very similar business model as ARM is using for their processors). It was describing the exact pixel structure cross section details and presenting mainly the benefits of that concept (and one of the benefits is the nonexistent color moire; the color accuracy they obviously didn't mention explicitly). The article was written so, it assumes the basic pixel sensor structure as the generic knowledge, used as one of the most common methods. Theirs was then the complete array design and the associated control and sensing electronic (and probably the color correction tables), likely in the form of some sort of "compiler" (you set in the basic parameters, like resolution in each direction and pixel size) and the compiler then generates the complete gds view (so the layout of all the layers in the target fabrication process) and simulation macro models (so you, as the final chip designer are able to verify all the complete IC will likely work well before even ordering the masks for 100+k$).
I would guess the use could be either for some lower cost cameras (I would guess for the mobile phones or so), or some special picture sensors (likely industrial machine vision systems, where the integration with special functionality was needed, hence as well the stressed no need for extra steps).
It was aimed for some TSMC 110nm node; these technologies are used by many IC companies (they design their own chip, but for fabrication use some foundry vendor technology - TSMC is one of the biggest such foundry service vendors)...
And here's fujifilm's filter: http://www.fujifilm.com/products/digital_cameras/x/fujifilm_x_t1/features/page_02.html
It looks like the micro lenses make the image smoother.
This looks more like some "higher end" sensor type, I doubt that would be used in any cost sensitive device like mobile phones or so.
