Abstract
In a period between an operation for acquiring signals for an image via an amplification unit and an operation for acquiring offset signals for correcting the image via the amplification unit, a current supply capability of the amplification unit is made equal to a current supply capability in a period immediately before the image is acquired, thereby the potential state of a signal line when the signals for the image are acquired and the potential state when the offset signals for correcting the image are acquired are matched, and an artifact when the correction is made is reduced.
