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.

Abstract: A small format factor camera system for mobile devices that provides improved image quality when using accessory lenses. The system may detect an accessory lens attached to the camera, either via sensing technology or by analyzing captured images. The system may analyze image data to determine current alignment (e.g., optical axis alignment, spacing, and/or tilt) of the accessory lens relative to the camera lens, and may shift the camera lens on one or more axes using a mechanical or optical actuator, for example to align the camera lens optical axis with the accessory lens optical axis. The system may also determine optical characteristics of the accessory lens, either via sensing technology or by analyzing captured images, and may apply one or more image processing functions to images captured using the accessory lens according to the determined optical characteristics of the accessory lens.
