APPRATUS AND METHOD OF NOISE RELIEVING USING NOISE TOLERANT OPTICAL DETECTION IN COMS IMAGE SENSOR BASED VISIBLE LIGHT COMMUNICATION

摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a noise mitigation technique using a noise-tolerant light reception technique in a CMOS image sensor based visible light communication method, and a noise mitigation device according to an aspect of the present invention includes a calculation unit for calculating a noise average value A background removal unit for removing the background of the signal value based on the calculated average value, and a normalization processing unit for processing normalization of the signal value from which the background is removed.
