Is this just a gimmick?

If you understand what the interpolated pixel feature does can you explain
it? maybe with reference to the following questions.

Is there any real use for this feature on a digital camera? Will it improve
prints? If so can software on a computer do just as good a job?

Found myself this page which explained a lot.

So yes I guess but very limited.

If printing large enough

Yes and better, more appropriate for use.

Feels like bad form to reply to my own post, feel free to join in.

YES---marketing hype. Fuji is the current worst offender

NO

maybe--see below

Up-sampling (interpolation)--in the camera or the computer---is uesful
to removed the jaggies and maybe to smooth out some noise and other
artifacts. It can never add to the inherent resoltuion of the
image---even if you are using Fuji super CCD diagonal pixels.

More control if you just take basic pix at full camera resolution and
then do the processing in the computer.

Everybody talks to themselves sometimes

You may want to check out Genuine Frcatals from http://www.lizardtech.com/solutions/gf/ - it
can produce larger printable versions of your images without tremendous loss of quality - of
course you will need Photoshop or Photoshop Elements to use the plug in and get the
bennifits - they also have a starter edition which appears good value ... Zol.

In the case of the Fuji cameras, the higher output resolution is
necessary to *retain* the resolution captured by the camera. A 3 MP
Fuji camera writing a 3 MP output image provides less total information
than other 3 MP cameras. A 3 MP Fuji camera writing a 6 MP image
provides the same total information as other 3 MP cameras, and more
horizontal/vertical resolution.

Whether the increase in horizontal/vertical resolution is useful is a
subject for debate, but the interpolation used in the camera is
*necessary* to retain that information while rotating the sampling grid.
It is not empty magnification like "digital zoom" on other cameras.

Very well put, Dave!
