Exactly. They do it on a frame-by-frame basis -- and
they're running 30 frames per second. It isn't very
useful for a digital SLR where the frame rate is only
a few frames per second.
Say, for example, that the 8MP CCD is ISO100 a
particular scene requires a 1/3 second exposure. In
order to accomplish image remapping, you'd have to
take several sub-1/3 second exposures and then combine
them. And if you could take a sub 1/3 second exposure
and get a usable image out of it, why bother with
anti-shake anyhow?
I'm not sure I'm explaining it very well, but to my
mind this approach doesn't make any sense for a
still-picture camera.
