METHOD OF DETECTING DATA TO BE TRANSMITTED IN VISIBLE LIGHT USING SENSOR OF STANDARD CAMERA Russian patent published in 2015 - IPC H05B37/02 H03M5/12 

FIELD: electricity.

SUBSTANCE: invention is referred to the sphere of lighting systems and optical receivers, and more specifically to the detection of data introduced into a light flux (output) of lighting systems. The invention suggests a system for the method detecting the first repeated sequence out of N symbols included into the first code, at that the first code is introduced into the light flux of the first light source of the lighting system, wherein the sequence contains at least N frames, and each frame out of at least N different frames is received with the total time of exposure containing one or more instants of the exposure, at that in each frame out of N different frames one or more instants of the exposure are in different time positions in regard to the first repeated sequence out of N symbols. The system contains a chamber to receive sequences of scene images through certain structures of an open/close state of the gate and a processing module to process the received sequence of images and to detect the repeated sequence out of N symbols.

EFFECT: development of the system for detecting data introduced into the light flux with high-frequency invisible modulation using standard commercial cameras in mobile telephones or web-cameras.
