It is not surprising that  a huge amount of money has been invested in sensors for mobile phone cameras. My research indicates that Sony has spent about two billion dollars in R & D to develop the Exmor RS series of HDR sensors. The way they work is quite logical. Where conventional Bayer sensors are comprised of a single layer of pixels, the Exmor RS sensors are comprised of three layers. Each layer is sensitive to a different level of brightness. So the camera basically captures and combines three bracketed images during a single exposure. This HDR capture also works for HD video capture. Exmor RS also incorporates back illuminated sensor technology which moves the wiring behind the photo-diode for increased sensitivity.

The new Sony Experia Z uses a 1/3 inch 13 megapixel version of this sensor. By the end of this year we may very likely a much larger 20 megapixel Sony Exmor Sensor in the “Sony Honami” smart phone. It seems to me that if this sensor is scaled up, we may find a future variation in a professional DSLR. I would love to be able to avoid motion artifacts in my HDR images using this technology!
