Dynamic resolution time of flight depth sensing

A non-transitory computer-readable storage medium comprising stored instructions, the instructions when executed by a processor of a depth camera assembly (DCA), causing the DCA to:

• illuminate a first region of a local area;
• select a first subset of a plurality of light sensors, the first subset of the plurality of light sensors configured to detect light from the first region of the local area and light sensors not in the first subset are inactive;
• detect light from a first portion of the first region of the local area using the first subset of the plurality of light sensors;
• determine depth information for the first region based in part on the detected light from the first portion of the first region;
• selecting a second subset of the plurality of light sensors, the second subset of the plurality of light sensors configured to detect light from the first region and light sensors not in the second subset are inactive,
• detecting light from a second portion of the first region of the local area using the second subset of the plurality of light sensors, wherein the determination of the depth information for the first region based in part on the detected light from the first portion of the first region is also based in part on the detected light from the second portion of the first region.

A depth camera assembly (DCA) comprising:

• a projector configured to dynamically illuminate one or more regions of a local area;
• a sensor configured to detect light from the illuminated one or more regions of the local area using one or more subsets of a plurality of light sensors;
• and
• a controller configured to:
• instruct the projector to illuminate a first region of the local area,
• determine a first subset of the one or more subsets of the plurality of light sensors,
• instruct the sensor to use the first subset of the plurality of light sensors to detect light, wherein the first subset of the plurality of light sensors captures light from a first portion of the first region of the local area,
• determine depth information for the first region based in part on the detected light from the first portion of the first region;
• select a second subset of the plurality of light sensors, the second subset of the plurality of light sensors configured to detect light from the first region and light sensors not in the second subset are inactive;
• instruct the sensor to detect light from a second portion of the first region of the local area using the second subset of the plurality of light sensors;
• and
• wherein the determination of the depth information for the first region based in part on the detected light from the first portion of the first region is also based in part on the detected light from the second portion of the first region.
