PROBLEM TO BE SOLVED: To allow for exact calculation of the light intensity change characteristics of light from a photometric target.SOLUTION: A calculation method of light intensity change characteristics has photometric means, and calculation means for calculating the light intensity change characteristics of light from a photometric target, on the basis of the results of photometry from the photometric means. The photometric means performs photometry a plurality of times at a predetermined period, the calculation means calculates a first evaluation value by determining a plurality of differences of the results of photometry where the interval of photometry becomes a first interval, out of the plurality of results of photometry obtained from the photometric means by performing photometry a plurality of times, while changing the set of the results of photometry, calculates a second evaluation value by determining a plurality of differences of the results of photometry where the interval of photometry becomes a second interval different from the first interval, while changing the set of the results of photometry, and then calculates light intensity change characteristics on the basis of the first evaluation value and second evaluation value. |
