An imaging apparatus includes a photometric lens for forming a secondary image of object light that has been transmitted through a lens unit and had a primary image formed by the lens unit, a photometric sensor for outputting a signal of the object light that has had the secondary image formed, and a PN liquid crystal panel located in the vicinity of a primary imaging plane. The imaging apparatus generates an image obtained by subjecting an output signal of the photometric sensor to reforming processing on the basis of an output signal of the photometric sensor when the PN liquid crystal panel serves as an object. Thus, the imaging apparatus can suppress a deterioration in the image that could be caused by various factors including a manufacturing error, a change over time, a change in temperature, and a change in humidity.
