<p>In an electron multiplying imaging device 1 including a solid-state image pickup device 10 having an image section 101a and an OPB section 101b, an image acquisition section 24a acquires a multiplied image at a predetermined electron multiplication factor set in advance, and a luminance calculation section 24b calculates a luminance average value and a luminance variance average value corresponding to the image section 101a in the multiplied image acquired by the luminance calculation section 24b, and calculates a luminance average value and a luminance variance average value of pixels corresponding to the OPB section 101b in the multiplied image. Then, by using the calculated luminance average value and luminance variance average value, a conversion factor calculation section 24c calculates a conversion factor of the multiplied image, and by using this conversion factor and a conversion factor at a reference electron multiplication factor, a multiplication factor calculation section 24d calculates an electron multiplication factor of the multiplied image.</p> |
