Abstract:
An imaging device provided with a read circuit in which a light-shielding region is formed in a part of an image region where a plurality of optical/electrical conversion devices is two-dimensionally arrayed in the row and column directions and which converts a optically detected signal outputted from each of the optical/electrical conversion devices for each of the column into a digital signal, comprises a storage device for storing the outputted digital signal outputted in relation with the optical/electrical conversion device in the light-shielding region and a difference calculation device for calculating a difference between the outputted digital signal in relation with the optical/electrical conversion device in a light-receiving region except the light-shielding region and a value stored in the storage device.
