Claim 21:
22. A method for detecting a peak time interval in a time-of-flight system, the method comprising:
incrementing a first count in response to a first-counter increment command;
decrementing the first count in response to a first-counter decrement command;
detecting a photon by a radiation-sensitive pixel, wherein, in a first state, the first-counter increment command is generated in response to the detecting, and wherein, in a second state, the first-counter decrement command is generated in response to the detecting;
receiving a timing signal that communicates an optical-emission time by an optical emitter;
transmitting a control signal;
setting the time-of-flight system to the first state after a passage of a first-state delay determined in accordance with the first count and measured from the optical-emission time; and
setting the time-of-flight system to the second state after a passage of a second-state delay determined in accordance with the first count and measured from the optical-emission time.
