1. A method for camera focus adjustment, the method comprising:
at a computing system, receiving a depth image of a surrounding environment captured by a depth camera of the computing system, the depth image including a plurality of depth pixels, and the plurality of depth pixels each encoding depth values corresponding to distances between the depth camera and objects in the surrounding environment;
identifying one or more depth pixels of the plurality of depth pixels as a region-of-interest (ROI); and
adjusting a focus of an environmental imaging camera of the computing system based at least in part on the depth values of the one or more depth pixels.
