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. ## Claims ### Claim 1 A system comprising: one or more processors; and logic encoded in one or more non-transitory computer-readable storage media for execution by the one or more processors and when executed operable to cause the one or more processors to perform operations comprising: detecting vibrations at an image sensor of a camera; determining a vibration signal from the vibrations, wherein the vibration signal includes one or more of a horizontal component and a vertical component; adjusting a phase angle of the vibration signal based on a lag between when the vibrations were detected and when one or more actuators are placed in motion; and sending the vibration signal to the one or more actuators, wherein the actuators dampen the vibrations. ### Claim 2 (depends on 1) The system of claim 1, wherein the vibration signal is within a predetermined frequency range of vibration sensors that detect the vibrations. ### Claim 3 (depends on 1) The system of claim 1, wherein the vibrations are high-frequency vibrations having a frequency that is above a predetermined frequency threshold. ### Claim 4 (depends on 1) The system of claim 1, wherein a reaction time of vibration sensors that detect the vibrations is a known value. ### Claim 5 (depends on 1) The system of claim 1, wherein the logic when executed is further operable to cause the one or more processors to perform operations comprising inverting the vibration signal. ### Claim 6 (depends on 1) The system of claim 1, wherein the logic when executed is further operable to cause the one or more processors to perform operations comprising phase shifting the vibration signal. ### Claim 7 A non-transitory computer-readable storage medium with program instructions stored thereon, the program instructions when executed by one or more processors are operable to cause the one or more processors to perform operations comprising: detecting vibrations at an image sensor of a camera; determining a vibration signal from the vibrations, wherein the vibration signal includes one or more of a horizontal component and a vertical component; adjusting a phase angle of the vibration signal based on a lag between when the vibrations were detected and when one or more actuators are placed in motion; and sending the vibration signal to the one or more actuators, wherein the actuators dampen the vibrations. ### Claim 8 (depends on 7) The computer-readable storage medium of claim 7, wherein the vibration signal is within a predetermined frequency range of vibration sensors that detect the vibrations. ### Claim 9 (depends on 7) The computer-readable storage medium of claim 7, wherein the vibrations are high-frequency vibrations having a frequency that is above a predetermined frequency threshold. ### Claim 10 (depends on 7) The computer-readable storage medium of claim 7, wherein a reaction time of vibration sensors that detect the vibrations is a known value. ### Claim 11 (depends on 7) The computer-readable storage medium of claim 7, wherein the instructions when executed are further operable to cause the one or more processors to perform operations comprising inverting the vibration signal. ### Claim 12 (depends on 7) The computer-readable storage medium of claim 7, wherein the instructions when executed are further operable to cause the one or more processors to perform operations comprising phase shifting the vibration signal. ### Claim 13 A computer-implemented method comprising: detecting vibrations at an image sensor of a camera; determining a vibration signal from the vibrations, wherein the vibration signal includes one or more of a horizontal component and a vertical component; adjusting a phase angle of the vibration signal based on a lag between when the vibrations were detected and when one or more actuators are placed in motion; and sending the vibration signal to the one or more actuators, wherein the actuators dampen the vibrations. ### Claim 14 (depends on 13) The method of claim 13, wherein the vibration signal is within a predetermined frequency range of vibration sensors that detect the vibrations. ### Claim 15 (depends on 13) The method of claim 13, wherein the vibrations are high-frequency vibrations having a frequency that is above a predetermined frequency threshold. ### Claim 16 (depends on 13) The method of claim 13, wherein a reaction time of vibration sensors that detect the vibrations is a known value. ### Claim 17 (depends on 13) The method of claim 13, further comprising inverting the vibration signal. ### Claim 18 (depends on 13) The method of claim 13, further comprising phase shifting the vibration signal.
