Abstract
Described are systems and methods to eliminate reflection from a display's incident light that is captured by a camera, such as a webcam. The display includes a polarizer that polarizes light which is reflected by a medium such as glass to the camera. The reflected light includes linearly polarized light. A polarizer is strategically placed in front of the lens set of a camera. Utilizing an orientation perpendicular to the reflected incident light, reflection from the reflective surfaces is eliminated before it enters the lens set of the camera.
