1. An electronic device comprising:
- a housing;
a finger biometric sensor carried by said housing;
a plurality of spaced apart first infrared (IR) emitters carried by the housing and configured to emit IR illumination toward a user;
at least one IR proximity sensor carried by said housing and comprising at least one second IR emitter configured to emit IR illumination toward the user, and an IR sensor configured to sense reflected IR illumination from the user;
a camera carried by said housing and configured to capture an image of the user'"'"'s face based upon the reflected IR illumination from the plurality of first IR emitters and the at least one second IR emitter; and
a controller configured toapply facial recognition to the captured image of the user'"'"'s face based upon the reflected IR illumination,perform at least one authentication function based upon the applied facial recognition, successively enable each of the plurality of first IR emitters,apply gesture recognition based on the reflected IR illumination reflected by the user'"'"'s hand when each of the plurality of first IR emitters is enabled, andperform at least one further authentication function based upon the finger biometric sensor.

Abstract
An electronic device may include a housing and at least one infrared (IR) proximity sensor carried by the housing. The at least one IR proximity sensor may include an IR emitter configured to emit IR illumination toward a user, and an IR sensor configured to sense reflected IR illumination from the user. The electronic device may also include a camera carried by the housing and configured to capture an image of the user'"'"'s face based upon the reflected IR illumination. The electronic device may further include a controller configured to apply facial recognition to the captured image of the user'"'"'s face based upon the reflected IR illumination.
