The Nikon website, in listing the specifications of the Nikon D800, says that it has 36.3 million effective pixels and 36.8 million total pixels.

It also says the image area is 7360 X 4912 which comes to 36,152,320 pixels or about 36.2 million pixels.

Can anyone explain the discrepancy? Perhaps there are extra pixels which contribute to the image but are not actually in the image area?
