Video camera with automatic subject tracking

It is very difficult to take handheld videos without shake. Especially when you are video-graphing pelagic birds, it is almost impossible to find the right balance to compensate the movement of the camera, movement of the boat, movement of subject due to waves and the movement of the bird! So what would be an ideal camera to film such things?

Such a video (can also be still) should have:

- ability to recognize and lock targets in a frame (say bird detection software :-)

- ability to move and rotate the lens in such a way that the subject is always in the center - so irrespective of camera position, the lens will always position in such a way that the subject is in center. This is something similar to the image stabilization, but with additional lens movement possible for the objective lens so that that is always at the right position. This can be achieved by detachable lens unit which is independently movable or multiple lens groups.

- ability to predict missing frames (in case of extreme movements of camera where even the lens movement is not sufficient to keep the subject in center)

So when will I get such a camera???
