APPARATUS AND METHOD FOR TRANSCEIVING OPTICAL SIGNAL USING MULTI-SPECTRAL OPTICAL ARRAY SOURCES AND CARMERA

摘要

PURPOSE: A method and device for transmitting/receiving an optical signal by using a multi-wavelength light source array and a camera are provided to perform optical communications by using a terminal or a device, which detects or stores image information by using an image device used as an image sensor, and a multi-wavelength light source array containing multiple light sources. CONSTITUTION: A camera module (110) transmits and receives an optical signal to and from the outside. A control part (120) is connected with the camera module. The camera module includes an image sensor and an optical transmission part. The image sensor photographs an external image. The optical transmission part transmits an optical signal to the outside.
