Abstract

A system and method or operating a webcam with 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 polarizer in a gear polarizer ring operatively coupled by a drive gear and arranged in front of an aperture for the webcam camera where the polarizer in the gear polarizer ring is rotatable to adjust a polarizer rotation orientation to reduce reflection in the images captured by the webcam camera, and the webcam microcontroller to execute computer-readable program code of an automated polarizer control system to adjust the rotation of the polarizer with the stepper motor based on a detected head angle of the user's face in the images captured by the webcam camera to reduce reflection in the images.
