DEVELOPMENT OF GENERIC COLORIMETRY SYSTEM FOR LIGHTING ENVIRONMENT BY USING CCD CAMERA

摘要

It is often measured a luminance distribution of a scene to evaluate an impression of architectural lighting environment. To get a luminance distribution, colorimetric system with CCD camera and fish-eye lens is generally used. Although several colorimetric systems have been developed by several research institute or manufacturer, not all the systems might provide us the photometric accuracy precisely. Therefore it disturbs a generic designer to use a colorimetric system. The purpose of the study is to develop a generic colorimetry system which is composed by commercial digital camera and fish-eye lens and to provide a convenient calibration method for general user.
