<p>PROBLEM TO BE SOLVED: To suppress occurence of a diffraction flare to acquire a photographing image.SOLUTION: An imaging device 1 comprises: imaging means 32 for photographing a subject image by an imaging optical system 21, and outputting the photographing image; brightness detection means 38 for detecting brightness of a photographing range of the imaging means 32; determination means 38 for determining whether a bright area is locally present in the photographing range on the basis of a detection result of the brightness detection means 38; aperture value calculation means 38 for, when it is determined by the determination means 38 that the bright area is locally present in the photographing range, calculating a recommendation aperture value; and adjustment means 23 for adjusting an aperture value of the imaging optical system to the recommendation aperture value.</p> |
