Claim Text:
1. A method of calibrating an optical device comprising a sensor and a plurality of movable lenses, wherein the sensor detects a position of at least one of the movable lenses, the method comprising: receiving a first signal from the sensor, wherein the first signal corresponds to a first position of the at least one of the movable lenses, wherein at the first position, the optical device at a minimum magnification setting; receiving a single input actuation so as to move simultaneously the plurality of movable lenses based on the single input actuation; receiving a second signal from the sensor, wherein the second signal corresponds to a second position of the at least one of the movable lenses, wherein at the second position, the optical device is at a maximum magnification setting; mapping a first point on a predefined magnification curve to the first signal; and scaling the predefined magnification curve such that a second point on the scaled predefined magnification curve is mapped to the second signal.
