Scanner Question: Enhanced dpi vs. Interpolated dpi

Hmm. I believe interpolation and enhanced are just two ways of saying the same thing. They digitally enhance the image quality.
 
From my understanding, interpolated means that you know 2 pixel colors but you don't know the pixel colors in between those 2 known colors.
So to fill the gap, it does not calculate the colors in between, but only predicts does colors and fill in that gap.
Is that correct?

So enhanced means the same thing?
 
They're the same thing. Different companies just using different terminology. There may be slight differences in the implementation, but the result is the same. Stick with optical resolution as a buying criteria.
 
I agree with Pariah, anything other than true optical resolution is just a way to make the resulting file bigger.
 
ok..
It says Canon has 1,200 x 2,400 dpi optical resolution while Epson has 1,200 dpi optical resolution.

So I guess that means Epson has 1,200 x 1,200 dpi?
Hence, Canon is the better choice?

I'm wondering if it's worth $170 for the Canon scanner...
