Super CCD

A type of CCD sensor from Fujifilm that is used in its digital cameras. Super CCD uses a honeycomb structure of octagon-shaped light sensors (photodiodes) at 45 degree angles rather than 90 degrees. Introduced in 2000 with its FinePix camera line, the diagonal design accommodates larger photodiodes that are closer together than the traditional row-column arrangement. In addition, the sensors more closely resemble nature and human vision. In 2003, Fujifilm introduced the following enhancements.

Super CCD HR (High Resolution)
After the Super CCD captures the image, Fuji's signal processing doubles the number of pixels for output, creating new pixels based on the colors from surrounding pixels.

Super CCD SR (Super Dynamic Range)
Mimicking the sensitivity and greater tonal range of analog color film, Super CCD SR uses a large and small photodiode for each color pixel (photosite). The large S-pixel is sensitive to normal and dark details, while the smaller R-pixel is less sensitive and used to capture bright details. The output of both sensors is mixed by the camera. In its second generation, the R-pixel is relocated in order to make the S-pixel larger.
