Claim 8:
9. A method of driving a liquid lens having a fluid interface, the method comprising:
obtaining a first gyroscope signal at a first time;
determining a first control signal configured to position the fluid interface of the liquid lens at a first position based at least in part on the first gyroscope signal;
applying the first control signal to the liquid lens to drive the fluid interface towards the first position;
obtaining a second gyroscope signal at a second time;
determining a second control signal configured to position the fluid interface of the liquid lens at a second position based at least in part on the second gyroscope signal; and
applying the second control signal to the liquid lens before the fluid interface has reached the first position to interrupt the motion of the fluid interface towards the first position and to drive the fluid interface towards the second position;
wherein the liquid lens has a response time that is longer than a time between obtaining the first gyroscope signal and obtaining the second gyroscope signal, such that the liquid lens operates as a filter on the gyroscope signals.
