Operation of IS in Canon S1

Archived from groups: alt.comp.periphs.dcameras (More info?)

Was it here once a discussion about how IS works, comparing to Minolta's,
which moves whole chip? well, i found out, how it works. It actually moves
one of the lenses according to shakes, so it's definitely NOT software
solution (and with it image degradation) like some of the people think!

Anyway, you read by yourself at this link:

    Intersting, so surley this would slow down operation as mini-gyroscopes have
    to work, this, and auto-focus would, I imagine, make shutter lag quite long.

    I see no difference with IS or without IS, so i guess it doesn't really
    slows down camera. I think that those gyroscopes are working independently
    and camera doesn't even knows they are there. The diffenence would be if
    this stabilization would be software solution...
    I think that Minolta has movable CCD sensor for this purpose , which i think
    can be less durable, since wires must vibrate along with sensor, which is
    not the case if only lens is moving.
