This isn't really anything new.
The technique is a very basic one based on an FFT of the image and the FFT of the blur direction. (I learned about it 8 years ago in one of my imaging classes)
Note that this works a LOT better if the blur is in a straight line.
Anyway, it does lose you resolution, but if you can apply it it does gain you a better end-image.
Obviously optical stabilisation is going to be a better idea (no blur to start with), but compared to high-iso this might just make the difference, especially if you are talking about images taking on the edge of handholdability.
If the adjustment is smaller the artifacts that are introduced are a lot smaller.
