1. A mobile device, comprising:

  • a rolling shutter camera;

    a processor coupled to the rolling shutter camera;

    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;

    set an image capture configuration for the rolling shutter camera, wherein the image capture configuration of the rolling shutter camera optimizes image capture for digital pulse recognition demodulation;

    adjust parameters of a demodulation function, wherein the demodulation function calculates image frequency content based on detected stripe width;

    capture an image using the rolling shutter camera according to the image capture configuration; and

    process the captured image using the adjusted demodulation function to obtain information from light based communication.
