Earlier this week, Aptina invited me out to their San Jose office to take a look at their new Clarity+ CFA (Color Filter Array) technology and 13 MP AR1331CP CMOS image sensor which includes it. Clarity+ is Aptina's new 2x2 RC,CB CFA which includes two clear pixels where the traditional Bayer array places green pixels. Others have tried (and failed) with clear pixel filter arrays in the past, Aptina believes it has the clear pixels in the right place with their new filter and the right opportunity with industry state and availability of powerful ISPs. Aptina claims it can realize a 3-4 dB improvement in SNR with Clarity+ over Bayer, while keeping the same sharpness, avoiding color artifacts that plagued other clear pixel filters...
