DEVELOPMENT OF GENERIC COLORIMETRY SYSTEM FOR EVALUATION OF LIGHTING ENVIRONMENT

摘要

To develop the lighting design method based on the comfort of the visual environment, it is necessary to have a luminance and chromaticity distribution measurement tool which is versatile and easy to construct the system. Therefore, it was developed a measurement system for luminance and chromaticity distribution of field of view using arbitrary digital camera. In this paper, it was examined the algorithm to convert digital camera images into the CIE XYZ tristimulus values and confirmed the photometric accuracy of their converted values.
