Abstract
Combining light detection and ranging (LIDAR) with the phase detection auto-focus (PDAF) capabilities of a sensor provides a robust emulation of a document camera on a collaboration endpoint device or system. LIDAR and PDAF can reliably indicate that an object is held close to the camera, PDAF can be used to focus and verify focus, and a snapshot image of the current scene can be sent over a presentation channel.
