US Patent 10362296 Localized depth map generation

Techniques involving localized depth map generation, the techniques including receiving pixel data for a frame captured by an image sensor, the pixel data including at least one light intensity value, corresponding to an amount of light received by the image sensor during a frame period, for each of a plurality of pixels; identifying a subset of the pixels as being associated with a physical object detected based on at least the pixel data; selecting a region of the frame, the region corresponding to at least the subset of the pixels; and selectively generating a localized depth map for the frame period corresponding to the selected region. A portion of the frame outside of the selected region is not associated with a depth map generated for the frame period.
