640 pixel count

I'm relatively new to thermal scopes I've owned one for about a year. My question is I have read that when you magnify a 640 core once it roughly becomes the same as a 320 core. A 640 core has roughly 306,000 pixels at 2× if it's cut in half that is roughly 156,000 pixels, a 320 core has roughly 76,000 pixels. I'm lost in this somehow seems the 640 at 2× should be much better than a 320 core at native resolution. Have I missed something?

A 640x480 1x scope at 2 times magnification will have the exact same resolution as at 320x240 scope that is the 2 power in its native resolution.


The problem is that you are thinking in one dimension instead of two. A 2 by 2 square is four times as large as a 1 by 1 square so A320 resolution scope is one quarter of the resolution of a 640 resolution scope

OK thanks.. now that makes sense, I wasn't thinking in those terms. I admit I was confused.
