1. A method to control the consumption of power by a platform that comprises a depth camera, the method comprising: receiving a depth image captured by the depth camera; determining that an object in a capture area represented by the depth image is in motion, based on the depth image; and in response to determining that the object is in motion, increasing an amount of light output by an infrared component from a first nonzero value to a second value and increasing a field of view of the depth camera, the depth camera using light output by the infrared component to determine depth information of the capture area.
