Abstract:
1. A stabilizer for an optical device that forms part of an electronic device; comprising: a platform wherein the optical device is mounted on the platform; a gimbal mount that retains the platform so that the platform is pivotal about a first axis and the gimbal mount being further pivotal about a second axis so that the optical device is pivotal about both the first and second axes, and wherein the second axis is offset from a center line of the camera module; a first actuator that is controlled to manage movement of the optical device about the first axis; a second actuator that is controlled to manage movement of the optical device about the second axis; a gyro sensor mounted with respect to the platform and wherein the gyro sensor outputs signals indicative of movement of the optical device about the first and second axes: and a controller that controls the first and second actuators in accordance with the output signals of the gyro sensor and the controller controls the first and second actuators to minimize change in the output signals from the gyro sensor; wherein the stabilizer does not include a position sensor to provide input to a controller indicative of relative position of any of the camera module, the platform or the gimbal mount.
