New Olympus patent describes a technique to reduce distortion with the on sensor stabilization

I found a patent that describes a way to use Olympus on sensor stabilization to correct for Distortions. Olympus writes:

According to the present invention, there can be provided a camera system and a camera body, which can execute, by a simple method, distortion correction with high precision, taking into account a shape variation of distortion on an image plane due to decentering of a vibration reduction optical system.

I read it multiple times and I cannot figure out well how this works. Hope more technical skilled readers can illuminate when reading the patent: freepatentsonline.com/10186021.pdf
