Abstract: The depth of one or more objects within a scene may be determined utilizing system that includes a single light source, a reflector (e.g., an ellipsoidal reflector), a shutter mechanism associated with the light source, and a camera. More particularly, the light source may output light that is directed towards the scene (a first set of light beams) and towards the reflector (a second set of light beams) utilizing the shutter mechanism. The reflector may reflect the second set of light beams towards the scene. The camera may then capture a first image that corresponds to the first set of light beams and a second image that corresponds to the second set of light beams. The depth of a particular one of the objects within the scene may be determined based at least in part on the first image and the second image.

Abstract: A device includes a projection and camera system to create an augmented reality environment in which images are projected onto a scene and user movement within the scene is captured. The projection and camera system have a camera to image scattered light from the environment and determine depth of objects in the environment. The system also has a projector to project the images onto the scene. The projection images and captured environment images share a common optical path through the same lens. The system includes an image noise cancelation system to cancel, remove, or otherwise reduce unwanted image noise caused by internal reflection of the projection images from the environment images.
