초록

본 논문에서는 실내 환경에서 색온도 검출이 가능한 이미지센서 모듈을 구현하였다. 이미지센서로 획득한 영상정보 내 색온도 정보는 색차조도계와 정합하여 LUT(Look Up Table)로 제작하였으며, 수광된 RGB값에 따른 색온도 정보가 자동 산출이 가능하도록 알고리즘을 개발하여 MCU(Micro Control Unit)에 반영하였다. 실내에서 이미지센서로 색온도를 측정한 결과 기준값 대비 5.91% 이하의 정확한 결과를 얻을 수 있었으며, 컬러센서를 이용한 색온도 측정 결과 대비 23.5% 이상의 균일도가 우수함을 확인하였다.

In this paper, we implemented an image sensor module possible of detecting color temperature in an indoor environment. The color temperature information in the video information acquired by the image sensor was matched with a color difference illuminometer to produce an LUT. An algorithm was developed so that color temperature information according to the received RGB values can be automatically calculated. As a result of measuring the color temperature with an image sensor indoors, an accurate result of less than 5.91% was obtained compared to the reference value. It was confirmed that the uniformity of 23.5% or more was excellent compared to the color temperature measurement result using a color sensor.
