A method in an electronic device includes determining, with one or more processors, an operating condition of the electronic device influencing one or more magnetic fields measured by a voice coil motor sensor of the electronic device. The method includes obtaining, by the one or more processors from a memory of the electronic device, an expected voice coil motor sensor measurement that is a function of the operating condition. Thereafter, the method includes causing, by the one or more processors, a voice coil motor driver to modify a voice coil motor drive signal until the voice coil motor sensor detects the expected voice coil motor sensor measurement, thereby compensating for effects of the operating condition affecting the voice coil motor.

An electronic device includes a gimbal driver and a digital camera. The digital camera includes suspension member(s) attached to a base. The digital camera includes a camera module supported by the suspension member(s). The camera module includes: (i) a lens that focuses an image; and (ii) a sensor attached to the lens and that detects the focused image. Shape memory alloy (SMA) actuator(s) are attached between the base and the camera module. The gimbal driver generates actuating signal(s) in response to movement of the base to stabilize the image. An electrical interconnect directs the actuating signal(s) from the gimbal driver to the SMA actuator(s) to rotate the camera module.

In aspects of automated polarizer filter positioning, a device includes a polarizer integrated with the device and auto-positioned to filter lighting of a camera scene. The device includes a camera device to capture a digital image of the camera scene using the polarizer at a rotation angle of the polarizer. The device implements an imaging manager to determine an orientation of the device relative to a position of the sun. The imaging manager can also determine the lighting of the camera scene as viewable with the camera device, and position the polarizer at the rotation angle based on the orientation of the device and the lighting of the camera scene to filter the lighting. The imaging manager can then initiate the camera device to capture the digital image of the camera scene with an imager of the camera device at the rotation angle of the polarizer.
