Increasing Image Resolution I know of some oscilloscopes (DSA8300) that repeatedly sample at a few hundred kS/s to reconstruct a few GHz signal. I was wondering if this could be extended to 2D signals (photographs). Can I take a series (say 4) of still pictures using a commercial 16MP camera to finally reconstruct a 32MP image? Will doing this remove aliasing I have from each image?

Should such a thing be attempted from a single image it would obviously not work as no new information is being introduced. If all the pictures taken are absolutely identical, will I still be at the same point as having one image? So are variations essential? Is CCD / CMOS noise enough variation for such a thing to work?

Is there a name for such a technique or algorithm? What should I look for?
One word for that technique is superresolution.

Robert Gawron has a blog post here and the Python implementation here.

Usually, this technique relies on each image being slightly offset from the others.  The only gain you'd get from not moving between shots would be to reduce the noise level.
