Claim 8:
9. A tangible, non-transitory, computer-readable medium, comprising computer-readable instructions, configured to cause a processor of a tracking device to perform operations comprising:
receiving a pulse signal from a tracked device, wherein the pulse signal indicates that an image frame to be presented by the tracked device comprises tracking data;
in response to the pulse signal, increasing an amount of power supplied to a camera subsystem;
transmitting a control signal to the camera subsystem to initiate an image capture operation while the image frame is presented by the tracked device;
receiving image data from the camera subsystem generated at least in part by the image capture operation;
identifying a location of the tracking data within the image data based at least in part on a comparison between the image data and a stored indication of the tracking data; and
performing an operation based at least in part on the location of the tracking data within the image data.
