Photons are the "signal". Each photon carries information, and is therefore a signal. A camera sensor records those signals on a sensor that integrates photons/unit area over time. A photographic sensor is just one way to measure the signal.

An intriguing view. May I ask what information a photon carries?

That it is there, and its energy.
