Abstract:
Systems and methods of optically stabilizing an image. A lens obtains optical image information corresponding to an image. An image sensor converts the optical image information into electrical image information. A rotation signal related to rotational movement of a camera unit is generated using a first motion sensor that provides a signal related to rotation when the camera unit is rotated. A translation signal related to translational movement of the camera unit is generated using a second motion sensor that provides a signal related to translation when the camera unit undergoes translational movement. The translation signal is modified using the rotation signal to generate a corrected translation signal that compensates for lens movement which is different from second motion sensor movement. The corrected translation signal controls an actuator that adjusts a lens position with respect to the image sensor, based on rotation and translation experienced by the camera unit.
