Abstract
Methods and apparatus for flexible illumination that improve the performance and robustness of an imaging system are described. Multiple different lighting configurations for the imaging system are pre-generated. Each lighting configuration may specify one or more aspects of lighting. A lookup table may be generated via which each pose is associated with a respective lighting configuration. A user may put on, hold, or otherwise use the device. A process may be initiated in which different lighting configurations may be selected by the controller to capture images of the user's eye, periorbital region, or face at different poses and in different conditions for use by a biometric authentication or gaze tracking process.
