1. A method comprising: obtaining input from a plurality of image sensors including at least a first sensor to capture a scene and a second sensor to track objects within the scene; combining the inputs from the plurality of image sensors to form a composite signal that encodes the scene from the first sensor and tracking data from the second sensor in the composite signal; and communicating the composite signal to an image sensor controller to cause the image sensor controller to generate an output image based at least in part upon the composite signal.
