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.

The new Super CCD HR (high resolution) incorporates a total of 6.63 million pixels into a 1/1.7" chip, performance made possible through new strides in miniaturization.
Fujifilm's Super CCD technology is also billed as allowing consumers to take pictures with less noise, even at the equivalent of higher film speeds, resulting in sharper pictures.

Building upon the characteristics of its critically acclaimed and user-popular FinePix 4900 Zoom predecessor and inheriting functions from the professional level FinePix S1 Pro, the FinePix 6900 Zoom features Fujifilm's second generation 3.3 million-sensor Super CCD that generates a 6-megapixel picture file.
Fujifilm's fourth-generation Super CCD technology is also an ingenious approach to sensor design, which now offers two different solutions: the Super CCD HR (High Resolution) chip incorporates 6.63 million pixels into a 1.0-by-l.7-inch sensor and, due to strides in miniaturization, the chip produces images with up to 12.3 million recording pixels.
Besides improving resolution by increasing the number of recording pixels to more than 12 million, the new Super CCD HR and Super COD SR imaging devices also offer greater dynamic range, avoiding loss of detail in dark areas and wash out in bright ones.
Using Fujifilm's Super CCD technology, the camera back will produce a broad dynamic range with a resolution of 5,408-by-7,648 (41.4 million) recorded pixels.
