Abstract
A system and method are disclosed for determining a depth map using TOF with low power consumption. In order to disambiguate, or de-alias, the returned distance(s) for a given phase shift, the system may emit n different frequencies of light over n successive image frames. After n frames of data are collected, the distances may be correlated by a variety of methodologies to determine a single distance to the object as measured over n image frames. As one frequency may be emitted per image frame, the depth map may be developed while consuming low power.
