A simplified colour calibration process for a digital web cam to be used for indoor illuminance measurement, enabling automatic, realtime, simultaneous measurement of illuminance of an indoor space at multi-locations based on its video image is proposed. Lab test results on 12 colours yielded 88% accuracy, which can be further improved in future work. � 2015 IEEE.
