  • Light-based communication using camera frame-rate based light modulation
    Patent number: 10542221
    Abstract: A method of Light-based Communication (LCom) using camera frame-rate based light modulation is provided. The method includes receiving light having modulated light properties that vary at a first frequency from a LCom-enabled luminaire by an image capture device using a global shutter image capture process, comparing light properties received at the image capture device over sequential image capture instances, and determining, from the compared light properties, data encoded by the modulated light.
