Optical camera communication (OCC) is a promising wireless communication technology that exploits the two-dimensional image sensor of digital cameras to capture and decode information sent through LED illumination. The OCC transmitter can include a single LED, an array of LEDs or a multi-pixel digital display.
The company has developed a novel OCC method that facilitates flicker-free communication between RGB-LED emitters and low framerate cameras. At the core of the method is a patented under-sampled color-switch modulation scheme that employs complementary color-pairs as data symbols. Since the pairs are "metameric matches" of the color white, the resultant LEDs illumination is perceived as uniform white to the human eye. The color-based modulation allows higher data-rate per each LED transmitter compared to similar monochromatic methods.
The technology facilitates unidirectional optical communication with electronic devices both indoors and outdoors.
Key features include:
Our OCC technology can be valuable for various applications – particularly in the smartphone space – requiring line-of-sight data transfer at low and medium rates.
