METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING OPTICAL SIGNALS USING MULTI-WAVELENGTH OPTICAL SOURCE ARRAY AND CAMERA

摘要

The present invention relates to an apparatus for communication using optical signals, including: a camera module for transceiving optical signals to/from the outside; a controller functionally connected to the camera module, wherein the camera module includes an image sensor for capturing an external image; and an optical transmitter for transmitting the optical signals to the outside, wherein the controller detects a first area through which the optical signal is received from the image captured by the image sensor, and performs control so as to receive an optical signal for each frame of the captured image from at least one optical source existing in the first area.
