2. A camera, comprising:
-
a plurality of electrostatic actuators configured to move at least one lens to implement image stabilization; a fixed portion on which the plurality of electrostatic actuators are supported to surround the at least one lens, wherein each of the plurality of electrostatic actuators comprises a movable portion configured to move, relative to the fixed portion, between a first position, in which the actuator is operable, and a second position, in which the actuator is non-operable; and a latch configured to latch the movable portion in the first position. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9, 10, 11, 12)

13. An actuator, comprising:
-
a plurality of electrostatic actuators configured to move at least one lens to implement image stabilization, wherein each actuator is configured to tangentially actuate the at least one lens in response to a motion of the actuator; a fixed portion on which the plurality of electrostatic actuators are supported to surround the at least one lens, wherein each of the plurality of electrostatic actuators comprises a movable portion configured to move, relative to the fixed portion, between a first position, in which the actuator is operable, and a second position, in which the actuator is non-operable; and a latch configured to latch the movable portion in the first position. - View Dependent Claims (14, 15, 16, 17)

18. A system, comprising:
-
a lens; a stage holding the lens within a curved aperture; three integrally formed tangential actuators symmetrically disposed about the stage in a fixed portion, each tangential actuator operable to displace the stage in a direction tangential to a curve defined by the curved aperture, wherein each tangential actuator comprises a movable portion configured to move, relative to the fixed portion, between a first position, in which the tangential actuator is operable, and a second position, in which the tangential actuator is not operable; and a latch configured to latch the movable portion in the first position. - View Dependent Claims (19, 20, 21)
