Abstract
An electronic device includes a time-of-flight sensor configured to sense a distance between the electronic device and at least one object proximate the electronic device. Processing circuitry is coupled to the time-of-flight sensor and controls access to the electronic device based on the sensed distance. The electronic device may include a digital camera that the processing circuitry controls to perform facial or iris recognition utilizing the sensed distance from the time-of-flight sensor.
