Video camera is on a tripod, zooms in, scans the scene...
Software then 'adds' all the footage together and
produces an ultra high quality image. A bit like a long
exposure this technique would not work for anything but
static shots (Even trees moving would confuse it) But,
then again you could
ignore people + cars - producing
people-free city scapes.
As an extention - using a video camera pointing at a Flat
mirror (which then moves around) you could use one
camera to take high-res images of the scene from 4
angles (+/-). If you're subtle with the mirrors, and had
sufficient camera quality these could be taken
symaltaniously. This would work well for a time-lapse
where you only have to buy one camera but get 4 films
out of it.
[edit 1]
responce to link "sounds a bit like this'"- my idea is the
opposite! but that's interesting. Summary: trading a
camera's high-resolution for low quality high-speed
video. I'd note that high-speed video requires a lot of
light, and in that case, you've got a number of options.
One is to just use 40 very cheap web-cams and stich the
footage together. (cant find link)
[edti2] sorry, its not fixed. The tripod is (ideally)
computer controlled - but even panning by hand should
work. It's better if the thing is ON a tripod - so the
perspective does not shift TOO much, and the more
sophisticated the tripod the easier the software is to
write. Not fixed though, sorry.
[edit 2] also, it might be able to get higher resolution
than even the zoom of the lens + the camera resolution
by deducing finer details through blur + moving the
camera a little. Using clever software which i'm sure
exists... Else it's worth half-baking.

more data =/= higher resolution, it simply means a large blurry file. Yes image processing can composite multiple frames in a video, to build a higher detail image by inference, but in a steady shot it would be worthless. |

Hmm, I do believe this might work. [+] |

Is that not precisely what [nicholaswhitworth] proposes? |
|

//but in a steady shot it would be worthless// |

It's not a steady shot though, is it? As the lens zooms in, each pixel of the imaging device will be scanning along a line from its starting point, towards the centre of the image. |
