EXPOSURE CONTROL APPARATUS

PROBLEM TO BE SOLVED: To match an integrated intensity with a reference value by performing operation for an amount of one-time exposure correction. SOLUTION: A normalized intensity integrating part 12 calculates, after calculating an integrated intensity S2, that has integrated an intensity S1 for each pixel constituting an image, a normalized integrated intensity S3, by dividing the integrated intensity S2 by a reference value TH; an exposure correction amount calculating part 13 calculates an amount of exposure correction S4 by performing a logarithmic operation on the normalized integrated intensity S3, calculated in the normalized intensity integrating part 12; and an exposure amount calculating part 14 corrects the amount of exposure S5 by using the amount of exposure correction S4 calculated in the exposure correction amount calculating part 13.
