1. A method of displaying a participant during a video conference against a blurred or otherwise unclear background, comprising: using an imaging device including an optic, an image sensor and a processor; determining different distances of two or more objects in a scene being captured in video, including performing an auto-focus sweep of the scene; generating a depth map of the scene based on the auto-focus sweep; identifying at least one of the objects as a foreground object or a background object, or one or more of each, based on the determining of the different distances; and blurring or otherwise rendering unclear at least one background object or one or more portions of the scene other than the at least one foreground object, or combinations thereof, also based on the determining of distances.
