Abstract
A sensor assembly for determining one or more features of a local area is presented herein. The sensor assembly includes a plurality of stacked sensor layers. A first sensor layer of the plurality of stacked sensor layers located on top of the sensor assembly includes an array of pixels. The top sensor layer can be configured to capture one or more images of light reflected from one or more objects in the local area. The sensor assembly further includes one or more sensor layers located beneath the top sensor layer. The one or more sensor layers can be configured to process data related to the captured one or more images. A plurality of sensor assemblies can be integrated into an artificial reality system, e.g., a head-mounted display.

An apparatus comprising:
- an array of pixel cells configured to capture one or more first images;
- and
- a processing circuit configured to:
- extract features of one or more objects from the one or more first images;
- and
- enable a subset of the array of pixel cells based on the features to capture one or more second images of the one or more objects.
A mobile device comprising:
- an sensor assembly comprising:
- an array of pixel cells configured to capture one or more first images;
