The SuperCCD SR (Super Dynamic Range) offers almost two stops more dynamic range than conventional CCD. Beneath each microlens on the sensor surface (a photosite) are two photodiodes, the primary captures a dark and normal light levels (more sensitive), the secondary captures brighter details (less sensitive). The signals from the two photodiodes are intelligently combined by the camera to deliver an image with extended dynamic range.
Unfortunately, this first SuperCCDSR will only have a 3 megapixel resolution. But this is very promising!
