Abstract
Various embodiments disclosed herein include devices, systems, and methods for spatially controlling illumination provided by a flash module. The flash module includes a flash controller that controls light emitters of an emitter array according to an illumination profile. The illumination profile is selected to reduce a relative brightness to a target region of the flash module's field of illumination. The target region is associated with a portion of a target object identified in the field of illumination. In some instances, the target region corresponds to a portion of a user's eye that is positioned within the field of illumination. In other instances, the flash module is incorporated into a device, and the target region corresponds to a reflected image of a portion of the device that is positioned within the field of illumination.
