Claim One:
1. A method of creating a depth map of a scene, comprising: at a computing device having one or more processors, and memory storing one or more programs configured for execution by the one or more processors: for each of a plurality of distinct subsets of IR illuminators of a camera system, receiving a captured IR image of a first scene taken by a 2-dimensional array of image sensors of the camera system while the respective subset of IR illuminators are emitting IR light and the IR illuminators not in the respective subset are not emitting IR light, wherein the image sensors are partitioned into a plurality of pixels; and for each pixel of the plurality of pixels: using the captured IR images to form a respective vector of light intensity at the respective pixel; and estimating a depth in the first scene at the respective pixel by looking up the respective vector in a respective pre-generated lookup table.
