Abstract:
1. A method comprising: verifying, through execution of a facial detection module stored in a memory communicatively coupled to a processor, whether an electronic display is illuminated by a light source at an active-mode luminous power level that is higher than a power-saving mode luminous power level thereof; periodically capturing, solely when the electronic display is verified to be at the active-mode luminous power level, a digital image of a face of a user, wherein the digital image does not require user intervention for the periodic capturing thereof; applying, with the processor, an algorithm associated with the facial detection module capable of detecting a digital facial feature of the face of the user based on a marker of the digital image; determining whether the periodically captured digital image comprises the digital facial feature according to the marker; maintaining the electronic display at the active-mode luminous power level when the periodically captured digital image comprises the digital facial feature; resetting, through the processor, a counter to an initial count value whenever the periodically captured digital image is determined to include the digital facial feature; allowing the counter to reach a final value thereof when the periodically captured digital image is determined to not include the digital facial feature; transitioning the electronic display to the power-saving mode luminous power level of the light source when the periodically captured digital image is determined to not include the digital facial feature; and maintaining the electronic display at the power-saving mode luminous power level of the light source when the periodically captured digital image does not include the digital facial feature until the user manually activates the electronic display.
