Abstract
An image pickup apparatus includes an image pickup unit having an optical black area, a control unit which reads a pixel from a selected area in a part of the image pickup unit, and a dark offset correction unit which sets a correction value acquisition area in the optical black area included in the selected areas. When the control unit performs a reading from a first selected area and a reading from a second selected area which at least partially overlaps with the first selected area, the dark offset correction unit sets a first correction value acquisition area set for the optical black area included in the first selected area and a second correction value acquisition area set for the optical black area included in the second selected area such that the first and second correction value acquisition areas at least partially overlap with each other.
