MEMS-based optical image stabilization

摘要

In one example, a camera is provided that includes: a plurality of MEMS electrostatic comb actuators, each actuator operable to exert a force on at least one lens; and an optical image stabilization (OIS) algorithm module operable to command the plurality of actuators to actuate the at least one lens responsive to motion of the camera.

1. A camera, comprising:
a plurality of integrally formed electrostatic actuators, each actuator configured to exert a force on at least one lens, wherein each actuator comprises a fixed portion, 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; an optical image stabilization (OIS) algorithm module configured to command the plurality of actuators to actuate the at least one lens responsive to motion of the camera; and a driver integrated circuit operable to drive the actuators responsive to the OIS algorithm module's commands.
