Abstract
Official abstract text for this publication.
An image pickup apparatus outputs a picked-up image signal based on a difference between an electric charge signal and a noise signal generated by a photoelectric converter. The apparatus has a generating unit that generates a difference image that is based on a difference between a first image picked up under a first image pickup condition and a second image picked up under a second image pickup condition in which an exposure amount of the photoelectric converter is smaller than the exposure amount of the photo electric converter in the first image pickup condition, a detector that detects a black spot area on the basis of the difference image generated by the generating unit, and a voltage controller that controls a clip voltage that is set to limit a voltage of the noise signal, on the basis of the detected black spot area.
