Abstract
A lens actuator is calibrated by inputting a signal to the actuator to cause the actuator to move a lens from a first location to a second location, sensing a focus error signal generated in response to the movement of the lens, determining a distance moved by the lens in going from the first location to the second location from a predetermined characteristic of the focus error signal, and determining a gain of the actuator from the input signal and the distance moved.
