Patent ID: 8405744

Claim:
An image-capturing apparatus comprising: 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 a region surrounding the effective pixel area; a storage unit configured to prestore a correlation between a dark current difference between each pair of adjacent 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 obtain, from the dark current of the light-shielded pixel area detected during the image capturing, dark current differences between each pair of adjacent areas during image capturing on the basis of the correlation stored in the storage unit; and a correction processor configured to correct a video signal obtained from the effective pixel area on the basis of the obtained dark current differences between each pair of adjacent areas during the image capturing.
