Abstract

A camera assembly for depth sensing of a local area. The camera assembly includes a projector, a sensor and a controller. The projector emits, into the local area, a structured light (SL) pattern at multiple phases. The sensor images the local area using multiple augmented pixels. Each augmented pixel has multiple gates and at least some of the gates have a respective local storage location. Each capture phase of the augmented pixel is divided into a respective plurality of time bins associated with a respective subset of the gates. Each local storage location of the subset of gates stores image data during a respective time bin, the image data based on portions of the SL pattern emitted at a respective phase and reflected from the local area. The controller determines depth information for the local area based on the image data stored during at least one capture phase.
