摘要： Different distances of two or more objects in a scene being captured in a video conference are determined based on applying a face model to a detected face within a digitally-acquired image. At least one portion of the scene other than the face is identified as comprising a background object that is a different distance from the video camera component than the face. The technique involves blurring or otherwise rendering unclear the background object.

摘要： Different distances of two or more objects in a scene being captured in a video conference are determined by determining a sharpest of two or more color channels and calculating distances based on the determining of the sharpest of the two or more color channels. At least one of the objects is identified as a foreground object or a background object, or one or more of each, based on the determining of the different distances. The technique involves 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.

摘要： Different distances of two or more objects in a scene being captured in a video conference are determined using an auto-focus sweep of the scene. A depth map of the scene is generated based on the auto-focus sweep. At least one of the objects is identified as a foreground object or a background object, or one or more of each, based on the determining of the different distances. The technique involves 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.

摘要： Different distances of two or more objects in a scene being captured in a video conference are determined based on applying a face model to a detected face within a digitally-acquired image. At least one portion of the scene other than the face is identified as comprising a background object that is a different distance from the video camera component than the face. The technique involves blurring or otherwise rendering unclear the background object.
