System and method for operating a web camera with automated anti-reflection adjustable polarizer

A method of executing computer-readable program code of an automated polarizer control system for a webcam comprising:

• executing the computer-readable program code of the automated polarizer control system, via a webcam microcontroller, to detect a user's face in images captured by a webcam camera and to detect a face angle from face landmarks of the user's face in the images;
• executing the computer-readable program code of the automated polarizer control system to determine from the face angle if reflection is occurring from the user's face based on a current rotation angle of a rotatable polarizer in a gear polarizer ring of an adjustable, automated polarizer device having the rotatable polarizer disposed in front of an aperture of the webcam camera and based on the face angle detected;
• and
• executing the computer-readable program code of the automated polarizer control system to generate a command to adjust a rotation of the rotatable polarizer with a stepper motor of the adjustable, automated polarizer device operatively coupled to the gear polarizer ring when the detected face angle of the user's face is determined to generate a reflection in the images captured by the webcam camera to reduce the reflection in the images.

A webcam operatively coupled to an information handling system comprising:

• a webcam microcontroller, a memory device, and a webcam camera to capture images of a user's face;
• an adjustable, automated polarizer device having a stepper motor and a rotatable polarizer in a gear polarizer ring arranged in front of an aperture for the webcam camera;
• the gear polarizer ring operatively coupled to the stepper motor via a drive gear set having a clutch and plural gears;
• the gear polarizer ring includes teeth and a stopper shelf around a portion of a circumference of the gear polarizer ring where the teeth are operatively coupled to the drive gear set to rotate a polarizer rotation orientation of the rotatable polarizer with respect to the aperture of the webcam camera and the stopper shelf engages an exterior holder ring having a rotation stop to trigger a clutch reset of the angle of the gear polarizer ring;
• and
• the webcam microcontroller to execute computer-readable program code of an automated polarizer control system to adjust the rotation of the polarizer rotation orientation of the rotatable polarizer with the stepper motor to mitigate reflection in the images captured by the webcam camera.
