Outline of Final Research Achievements

The LED-lighting market is still expanding, with the increasing number of new-coming manufacturers. For the performance evaluation of LED lightings, various expensive measurement devices and software products are used, such as an illuminometer and simulation software. However, purchasing all such products is difficult for newcomers. In this study, an environment for measuring the illuminance has been devised, using a digital camera, such as the cell-phone camera which has been indispensable in everyday life. It has been revealed that the illuminance value can be predicted by using a histogram of an image taken with a digital camera.
