Not an expert, but I think part of what you’re describing is an illusion. Our brains do a lot of work to trick us into thinking we see everything that we expect to be in our FOV. Blind spots demonstrate this. For me, when I turn my head, my apparent FOV rotates, while when I move my eyes, it does not. However, when my eyes are looking far right, I can no longer actually detect motion in the far left of my FOV. even though that part of the scene still feels like it’s visible, it isn’t. Anyway, I think the technology equivalent is just called stabilization. Again, our brains are really good at tricking us into not noticing it happening. But if you could view the “raw feed” from the optic nerves, it wouldn’t look anywhere near as clean as your description suggests.
