Questions about the Fuji chip

    Fuji 602 and other models have a chip that is octagonal and doubles the size
    of the file so that a 3 megapixel camera gives a 6 megapixel image.

    Is this legitimate or partly legitimate?
    Is all or some part of this camera's file size doubling due to interpolation
    or is it partly more physical pixels?
    If it's a bit of one and and bit of the other, what % is just interpolation?

    Thanks

  2. Don't think of it as an increase in resolution. It's not. Not very
    much. Well, there's a *little* increase in resolution. The Fuji S2
    is a 6 megapixel camera, not a 12 megapixel camera. The dpreview.com
    review does seem to show some measurable increase in resolution.

    The benefit is that the pixel well is bigger and fills more of the
    cell. It's more efficient, lower noise, better in those sorts of
    ways.

    Of course, because he's measuring horizontal and vertical resolution.
    If you rotate a sensor 45 degrees, your H/V resolution goes up by 1.4
    and your diagonal resolution down by 1.4. No such thing as a free
    lunch, and all that.
    I haven't seen any real numbers to support the idea that the fill
    factor of the Fuji sensor is better. It might be, but it doesn't
    follow that the Fuji arrangement will make it so.

  4. I read a review in UK's excellent mag Professional Photographer (be
    equally excellent editor and reviewer Steve Hynes), and he concluded
    that the F2 has a better image quality than a normal 6-megapixel chip
    would have. But that it is not equal to a 12 megapixel chip at all.
