Abstract
An imaging device according to the present invention has: a photometric circuit that detects a brightness of a photographic subject based on a light flux from the photographic subject that passes through a photographic lens; an exposure calculation circuit that calculates an aperture value and a shutter speed based on the detected brightness of the photographic subject; an imaging element that converts the light flux from the photographic subject received on each photo-electric element to an electric signal and outputs the electric signal, the imaging element having a plurality of the photo-electric elements and a micro-lens in which each of micro-lens elements is arranged facing to each of the photo-electric elements in order to converge the light flux from the photographic subject to a light receiving surface of each of the photo-electric elements; and a correction circuit that corrects the aperture value calculated by the exposure calculation circuit so that a signal level of the electric signal of the light flux does not change among photographic subjects each having a same brightness respectively.
