IMAGE-CAPTURING APPARATUS, IMAGE-CAPTURING METHOD, AND PROGRAM

摘要

An image-capturing apparatus includes an image-capturing device having an effective pixel area formed of a plurality of areas having different dark current characteristics and a light-shielded pixel area arranged in the region surrounding the effective pixel area; a storage unit configured to prestore a correlation between dark current differences among the plurality of areas and dark current of the light-shielded pixel area; a detector configured to detect the dark current of the light-shielded pixel area during image capturing; a dark current difference obtaining unit configured to, on the basis of the correlation stored in the storage unit, obtain dark current differences among the plurality of areas during image capturing from the dark current of the light-shielded pixel area; and a correction processor configured to correct a video signal obtained from the effective pixel area on the basis of the dark current differences during the image capturing.
