Abstract
An image pickup apparatus which is capable of accurately compensating for noise even when images are continuously taken at varying exposures. First and second image signals corresponding to the first and second exposures are output. The first and second image signals are subjected to a noise compensation process and then synthesized together to obtain a composite image signal. Data obtained in the first and second image signals when the noise compensation process was carried out on the first and second image signal is inherited, and a noise compensation process on the next first and second signals is carried out based on the data.
