S2, like its predecessor the S1, has a proprietary "Super CCD," but the device has increased resolution, with approximately 6 million sensor elements arranged in a honeycomb pattern.

Because the sensors are is arranged along a diagonal rather than a traditional array of rows and columns, each photosite is larger, and gathers more light with improved signal as compared to a traditional arrangement. Also, because of this arrangement the sensor data needs to be interpolated in order to be displayed as a traditional image.
This interpolation process increases the native image resolution to 12 million pixels, but in practice the effective resolution is probably somewhere around what you would expect from a sensor of about 9 million pixels.
The S2 provides the ability to capture images in different modes, including RAW, JPEG and TIFF formats.
