Canon Patent Application: IS unit with better control over vignetting

I wasn't necessarily going to post this patent application, however, after seeing this other places, I felt it necessary.

This patent is being described as IBIS, but it's not, the IS unit is solely in the lens as it stands now for Canon cameras.  This patent application describes techniques to reduce vignetting when an IS unit is active in the lens.  As the amount of vignetting that can occur will change as the optical axis moves (IS being active in the lens)

There is no mechanism around the sensor for IBIS, or actually moving the sensor, which would be identifying an IBIS system.

Canon has had patents in the past, which show a varying degree of sensor movement to facilitate different goals, however, as far as we can tell, they haven't yet issued out a patent for pure IBIS yet.
