PC Stats review of the FinePix F402, Fujifilm’s stylish new 2.1 megapixel digital camera. The F402 has Fujifilm’s latest SuperCCD sensor, which supposedly translates images into 4 million effective pixels:
The technology behind Fujifilms’ Super CCD revolves around how the CCD sensor is constructed, and how the octagonal photodiodes themselves are oriented in a honeycomb pattern. The octagonal shape is more efficient at capturing light, and thus produces a stronger electrical charge in the pixels, yielding higher sensitivity. The honeycomb structure is significant in that the spaces between the photodiodes are smaller than with other technologies. With less space between the sensors, there is improved resolution, and hence better image representation. That is why we see a doubling up of actual pixels to “effective pixels” in the marketing spec sheets. Effective pixels are representative of a standard CCD sensor with about twice as many actual pixels for the most part.
The F402 is tiny too, just 3″ x 2.7″ x 0.9″, and weighs only 145 grams.
