Abstract
An imaging apparatus includes a clamp level is multiplied by a first feedback gain, and correct a signal of a part of photoelectric conversion portions of a unit pixel in an opening region based on a result of multiplication in which an error amount between a signal of a part of a photoelectric conversion portions of the unit pixel in a light-shielded region and a clamp level is multiplied by a second feedback gain, and thus the signal of the unit pixel can be corrected precisely.
