Abstract
An information handling system camera captures visual images of light directed by a lens towards an image sensor. The camera has an active illumination privacy shutter that disables the image sensor from capturing visual images by introducing illumination between the lens and image sensor, such as with a red light emitting diode that is seen as a red dot at the lens when viewed from in front of the camera. In one embodiment, the illumination is directed towards a light diffuser, such as a sheet of acrylic, that extends between the lens and image sensor when the camera is commanded to a privacy mode.
