Physically based camera motion compensation
Implementations generally provide physically based camera motion compensation. In some implementations, a method includes detecting vibrations at an image sensor of a camera. The method further includes determining a vibration signal from the vibrations, wherein the vibration signal includes one or more of a horizontal component and a vertical component. The method further includes sending the vibration signal to one or more actuators, wherein the actuators dampen the vibrations.
