I doubt that you'll find any good angular sensors that respond that
quickly in the price range needed for digital cameras.

I think that it MAY be possible to do some after-the-fact  motion
compensation on a single frame.  You treat each pixel as integrator
which sums the light input over the exposure time.  If you have some
knowledge of the image motion on the focal plane during the exposure,
you have a better handle at undoing the motion blur.

Don't forget that the displacement at the pixel plane is a function of
the focal length of the lens.  You would need to know both angle and
direction of motion as well as the focal length to compute image
displacement in pixels.

About as possible as turning .hex files back into C source, or
hamburgers back into cows.  A video frame made with an unsteadily held
camera that shows any artefacts caused by this is completely munged
up.  Un-munging just doesn't work.

You need a lot of extra knowledge about what's in the picture for any
kind of motion blur reduction to actually work.  It may well end being
so much much additional information you could just _paint_ the picture
from scratch ;-)

Re: Idea exploration - Image stabilization by means of software.
Mark u r right. There is no sensor that can respond as fast as 1us.
However, image stabilization only becomes useful when the shuttle
speed is slower than 1/50 I guess. In this 1/50second, one can
divide the sampling interval of the angular sensor to be 1/500, i.e.
2ms, is this still difficult?
