It does if the pulse they are sending out to measure is IR. IIRC the picture image is captured at a different time to the depth. Sunlight and reflective materials were a problem with all the cameras we were looking at. In any case I thought the kinetic camera was using structured light - as it has a projector which projects a pattern on the scene, ir camera to measure it and a normal rgb camera. The ir camera and rgb camera are seperate, so you get the shadow effect you can see in the depth images - time of flight cameras use the same lens so are a little better. cheers, dave
