In this paper we assess the quality of colorimetric calibration of HDR images captured using
the multi-exposure technique. Three cameras were used to take HDR photographs of 4 …

ABSTRACT High Dynamic Range Imaging (HDRI) is an increasingly popular technique for
studying the lighting environment through luminance maps. However, a thorough calibration …

The principle and calculation process of getting the luminance distributed matrix by single
point spectral irradiances scanning method were discussed. The luminance distributed …

This paper reports the results of measurements performed in a test room to test how digital
camera can be used as luminance meter and thus to investigate the lighting control scheme …

Abstract High Dynamic Range Imaging (HDRI) techniques for luminance measurement is
gaining importance in recent years. This paper presents the application of the HDRI system …

A method of calibration of imaging luminance measuring devices has been studied. By the
device-independent color space transformation, the color image by digital camera could be …

抄録 LED lighting technology has been advancing quite rapidly. The luminance distribution
in LED floodlights is assumed to differ from that of high-intensity discharge (HID) floodlights …
