CCD (Charged Coupled Device): A silicone chip comprised of millions of tiny, square light-gathering diodes called Picture Elements, or pixels, laid out in a checkerboard pattern. This is the "film" of a digital camera. The light data gathered from these tiny pixels needs to be "processed" by the camera's image processor into Recorded Pixels.
Super CCD: A proprietary CCD system, produced by Fujifilm, that utilizes larger, octagonal-shaped, light-gathering diodes called Picture Elements, or pixels, that are laid out in a saw-tooth pattern. Super CCDs can capture more light information than ordinary CCDs; the extra information is used by the camera's image processor to improve color accuracy and ISO Speed.
Super CCD HR (High Resolution): Is capable of nearly doubling the Number of Effective Pixels that are processed and stored as additional detail in the Recorded Pixel file.
Super CCD SR (Sensitivity and Range): Uses a combination of small and large octagonal-shaped pixels to further enhance color accuracy, while improving detail in the areas of shadows and highlights, much like traditional film
