Abstract
In accordance with an example embodiment, an apparatus comprises a printed wiring board. The printed wiring board comprising a coil and being coupled to an image sensor. The coil, using the magnetic circuitry, is designed to tilt the printed wiring board and automatic focus optomechanics, the automatic focus optomechanics being attached to the printed wiring board over a gimbal pivot system to operate an optical imaging stabilizing system. A second coil is designed to interact with the magnetic circuitry to move the lens barrel at least one of closer and farther from the image sensor to perform an automatic focus. An apparatus comprises a lens barrel comprising at least four coils. The at least four coils each configured to interact with respective magnet circuitry. The at least four coils and respective magnetic circuitry capable designed to tilt the lens barrel in such a manner as to correct an imbalance.
