Abstract:
An AD conversion unit AD-converts a first analog signal output from a clamping unit and generated based on a signal generated at a first photoelectric conversion unit. Then, while the first analog signal is clamped at a reference level, signals generated based on the signals generated at the first and second photoelectric conversion units are applied to the clamping unit, whereby the AD conversion unit AD-converts a second analog signal output from the clamping unit.
