Abstract
An apparatus is described that includes an integrated two-dimensional image capture and three-dimensional time-of-flight depth capture system. The three-dimensional time-of-flight depth capture system includes an illuminator to generate light. The illuminator includes arrays of light sources. Each of the arrays is dedicated to a particular different partition within a partitioned field of view of the illuminator.

(canceled)
A depth camera comprising:
- an illuminator having a field of view and comprising a plurality of arrays of light sources, wherein each array of light sources is associated with a respective sub-region of the field of view;
- an optical element comprising (i) a planar, source surface that faces the illuminator, (ii) a planar, emission surface that is obverse to the source surface, and (iii) a plurality of arrays of micro-lenses positioned on the source surface, wherein each micro-lens is aligned with a respective light source, and wherein each micro-lens collects light emitted by its aligned light source and causes the light to be less divergent internal to the optical element, and wherein the optical element directs light emitted from the light sources of each array to a respective sub-region of the field of view that is associated with the array;
- and
- an image sensor configured to receive light that is (i) emitted by the illuminator, and (ii) reflected by an object of interest.
