Abstract
An information handling system camera supports plural filters selectively inserted between a lens and an image sensor by plural actuators disposed around the perimeter of the lens and image sensor so that the actuators do not add to the vertical height of the camera. Plural actuators support simultaneous insertion of plural filters that cooperate to offer day, night, distance detection and camera focus distance and zoom levels by refractive manipulation of light passing through a neutral density (transparent) piece of material of an increased thickness.
