Abstract:
A camera assembly for determining depth information for a local area includes a light source assembly, a camera assembly, and a controller. The light source assembly projects pulses of light into the local area. The camera assembly images a portion of the local area illuminated with the pulses. The camera assembly includes augmented pixels, each augmented pixel having a plurality of gates and at least some of the gates have a respective local storage location. An exposure interval of each augmented pixel is divided into intervals associated with the gates, and each local storage location stores image data during a respective interval. The controller reads out, after the exposure interval of each augmented pixel, the image data stored in the respective local storage locations of each augmented pixel to generate image data frames. The controller determines depth information for the local area based in part on the image data frames.
