Patent ID: 8564694

Claim:
An image pickup device, comprising: a charge coupled device having an image pickup area and a storage area; a control unit for vertical-transferring signals of a predetermined line number that have no pixel signal from a vertical transfer register of the storage area and vertical-transferring more lines than the number of lines of a vertical transfer register of the image pickup area by the predetermined line number to the vertical transfer register of the storage area during a vertical blanking period; an image signal obtaining unit for obtaining image signals outputted from predetermined pixels of the charge coupled device as a first image signal; an obtaining unit for obtaining the signals of the predetermined line number that have no pixel signal of the storage area as a second image signal; and a correction unit for subtracting a value corresponding to the second image signal obtained by the obtaining unit from the first image signal obtained by the image signal obtaining unit, wherein the control unit typically vertical-transfers the signals of the predetermined line number that have no pixel signal, and wherein after typically vertical-transferring the signals of the predetermined line number that have no pixel signal, the control unit vertical transfers more lines than the number of lines of a vertical transfer register of the image pickup area by the predetermined line number to the vertical transfer register of the storage area.
