Patent ID: 6952291

Claim:
An imaging device, comprising: 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, the photographic lens being exchangeable and outputting information regarding the photographic lens; an exposure calculation circuit that calculates an aperture value and a shutter speed based on said detected brightness of the photographic subject; an imaging element that converts the light flux from the photographic subject into an electric signal and outputs the electric signal, the amount of light flux received from the photographic subject being controlled by said aperture value and said shutter speed, said imaging element being separate from said photometric circuit and having a plurality of photo-electric elements and a micro-lens with a plurality of corresponding micro-lens elements, said micro-lens elements facing said photo-electric elements to converge the light flux from the photographic subject to a light receiving surface of each of said photo-electric elements, wherein the electric signal output by said imaging element represents a captured image of the photographic subject; a correction circuit that obtains the information regarding the photographic lens from the photographic lens and corrects a change in sensitivity of the imaging element based upon the information regarding the photographic lens; and a correction pattern memory that stores a plurality of correction patterns to correct a change in sensitivity of said imaging element, said correction patterns respectively corresponding to a plurality of said micro-lenses that have different characteristics respectively, wherein: said correction circuit reads out said correction pattern corresponding to said micro-lens of said imaging element from said correction pattern memory, and corrects a change in sensitivity of said imaging element based upon said read out correction pattern and the information regarding the photographic lens.
