A depth imager such as a time of flight camera or a structured light camera is configured to capture a first frame of a scene using illumination of a first type, to define a first area associated with an object of interest in the first frame, to identify a second area to be adaptively illuminated based on expected movement of the object of interest, to capture a second frame of the scene with adaptive illumination of the second area using illumination of a second type different than the first type, possibly with variation in at least one of output light amplitude and frequency, and to attempt to detect the object of interest in the second frame. The illumination of the first type may comprise substantially uniform illumination over a designated field of view, and the illumination of the second type may comprise illumination of substantially only the second area. |
