Abstract
A solid-state imaging device includes M pixel units to and a correction unit. The pixel unit includes a main amplifier, a capacitive element, a first switch, a second switch, a photodiode, a feedback capacitive element, and an initialization switch. The correction unit includes a null amplifier, a capacitive element, a first switch, and a second switch. An effective offset voltage of the main amplifier is small.
