摘要

PROBLEM TO BE SOLVED: To provide a device for determining presence or absence of direct light which is maintained readily and is able to accurately determine the presence or the absence of the direct light.SOLUTION: The device includes imaging means 2, 3 and 4, which pick up a sky image of the whole sky for each prescribed time interval; a luminance distribution calculating means 5 which calculates the brightness distribution of the sky image; a solar position calculating means 5, which calculates a solar position on the luminance distribution; and a determining means 5, which determines the presence or absence of the direct light on the basis of the luminance distribution.
