Abstract
Various embodiments disclosed herein include optical aberration control for a camera system. Such a camera system may implement optical aberration control, e.g., by combining one or more variable focus devices with one or more actuators (e.g., a voice coil motor actuator) for moving a lens stack of the camera system to provide autofocus (AF) and/or optical image stabilization (OIS) functionality. A variable focus device may have variable optical power to achieve AF, OIS, and/or introduce optical aberrations such as spherical aberration. In some implementations, the variable focus device may be driven to introduce optical aberrations, and the actuator for moving the lens stack may be driven to compensate for the optical power from the variable focus device.
