Interpolated means artificially created resolution. You don't actually
get more detail.
Imagine an image formed from the following bitmap:
***

Take that as being the actual resolution of a device. Now, double
everything up.

You get a bigger, but chunky picture. Interpolating is increasing the
picture size, but not as a simple doubling up. It's making assumptions
about what would be in between the original picture. It'd space apart
the original data, and fill in the dots between (as a simplistic
approach). So you'd get a much more triangular-looking object than my
second example (less steps).
Depending on how good the interpolation is, it will look better than
simply magnifying the picture, but not as good as a picture that
actually was higher resolution.
