Abstract: New systems and methods are hereby provided that inherently and naturally resolve the challenges of synthesizing coordinated inputs from multiple cameras. For example, a multi-sensor mediator may collect the input data from multiple sensors, and generate a composite signal that encodes the combined data from the different sensors.

A computing device that receives the input from the sensor controller may then generate an output based on the composite signal, which may include processing the composite signal to combine the separate signals from the different sensors, such as to provide a stereo image output, for example. The multi-sensor mediator makes such an output possible by ensuring coordinated input and processing of the input from the multiple sensors, for example.
