<p><P>PROBLEM TO BE SOLVED: To restore each illumination condition of a plurality of lighting system installed in a photographing studio to an original optimum illumination condition even in the case where luminous energy or the like of the lighting system is changed due to temporal change after the illumination condition is once set in the optimum condition. <P>SOLUTION: A reference object 20 is installed at a standing position of the photographing studio, and is photographed by a digital camera 40 by illuminating it with lighting systems 11-13 of which the illumination conditions are so adjusted as to optimize illumination to the reference object 20. Color data of a plurality of reference points P1-P3 on the reference object are acquired from color image data obtained by the photographing to store them. Thereafter, color data of the reference points P1-P3 on the reference object are acquired at an arbitrary time as the above; a difference amount between the stored color data and them is calculated to calculate the variation of the illumination condition of each of the lighting systems 11-13 based on the difference amount; and the illumination condition of each of the lighting systems 11-13 is adjusted based on the calculated variation. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
