How does image stabilizing work?

So I understand the mirror inside the DSLR can slightly shake, how does image stabilizer through video correct the problem?

I think if shifts the lense left.right/up/down based on the image movement.

If I were going to attempt to write the software I would create a buffer along the edges of the image like a picture frame, and crop the image. I would compare each frame to the one before it and look for closely matching pixels and try to line up the two frames by shifting them up/down/left/right in the opposite direction of the motion. This may be a completely wrong approach, and I suspect that modern software is a lot more sophisticated than this.
