1. A mobile device, comprising:

  • an image sensor;

    a processor coupled to the image sensor;

    a memory; and

    software in the memory to be run by the processor, wherein running of the software by the processor configures the mobile device to implement functions, including functions to;

    determine that the mobile device is in a location enabled with light sources that generate modulated visible light signals;

    in response to the determination, initialize parameter settings of the image sensor including locking an exposure setting of the image sensor to optimize the image sensor to receive the modulated visible light signals generated by the light sources;

    capture using the image sensor according to the initialized image sensor parameter settings an image containing a representation of a modulated visible light signal generated by one of the light sources in the location; and

    obtain information from the visible light signal generated by the one light signal by demodulating the representation of the modulated visible light signal contained in the captured image.
