In an implementation, the system may include an endoscope having an image sensor, an emitter, and a control circuit. The control circuit controls a frequency of the emitter in response to signals that correspond to the frequency of the emitter.

Signal transitions are encoded within output data from the image sensor and correspond with defined states.
