Why does the world bounce around when viewed through a camera while walking but stay steady when just using my eyes?

If I hold a camera and walk, when I view it later it makes me nauseous. Running with a camera is even worse (obviously). How do our eyes filter out the bouncing? Do they somehow stay steady while our heads bounce or does the brain somehow filter it to make everything appear much more stable?

The vestibular system corrects for motion and smooths it out.

You can "bypass" this by closing one eye, then taking your finger and repeatedly (but gently!) pushing your other eyeball to the side. You will see the world move around as you push, because your vestibular system isn't aware of the force that's causing your eyeball to move.
