Abstract:
Each pixel of a plurality of pixels captures a portion of outgoing light illuminating a local area reflected from the one or more objects in the local area. A flag is generated via a flag determination logic circuit coupled to each pixel of the plurality of pixels. The flag indicates whether the reflected light was captured within a threshold amount of time from a current time. A time to digital converter is enabled via a flag determination logic circuit. The time to digital converter is associated with each pixel of the plurality of pixels to generate a digital representation of time when each pixel of the plurality of pixels captured the reflected light. Depth information is determined for the one or more objects in the local area based in part on the generated flag and the digital representation of time.
